Dear Ms. George:
Re: Trans Mountain Pipeline ULC (“Trans Mountain”) Trans Mountain Expansion Project - Certificate OC-65 Condition 26: Burnaby Mountain Tunnel Option Revised Response to Information Request No. 20.2 (“IR No. 20.2”) CER File OF-Fac-Oil-T260-2013-03 61
In response to the CER’s IR No. 20 [C04160] with respect to its prior submissions concerning Condition 26 (Burnaby Mountain Tunnel Option), Trans Mountain filed a submission on February 7, 2020 [C04607].
Upon further review, Trans Mountain became aware that there were inconsistencies in Trans Mountain’s IR No. 20.2 response concerning a previously filed document, namely the Lower Mainland Project-Specific Safety Plan (PSSP) that was filed on June 23, 2017 [A84570]. Trans Mountain realized that its IR 20.2 response referenced a revised and updated version of the PSSP that had not been submitted to the CER. On March 6, 2020, Trans Mountain filed this revised PSSP [C05072].
Having made some minor revisions to its prior response to address the inconsistencies noted above, Trans Mountain resubmits its response to IR No. 20.2, with changes shown in blackline.
Suite 2700, 300 – 5 Avenue SW Calgary, Alberta, T2P 5J2 CANADA
Should you have any questions or wish to discuss this matter further, please contact the the undersigned at [email protected] or (403) 514-6400.

Preamble:
Reference i) requires, among other things, Trans Mountain to file with the Commission, for approval, the Burnaby Mountain tunnel (Tunnel) confined space entry procedures.
In Reference ii) Trans Mountain stated that although the Tunnel is not considered a confined space under the Canada Occupational Health and Safety Regulation (COHSR), Part XI regulations, the specific safety requirements of the COHSR regulations will be followed on the Project. The reference further stated that Trans Mountain considers the Tunnel to be an ‘underground working’, under Worksafe BC Underground Workings.
Page 1 of 4 Trans Mountain Pipeline ULC (Trans Mountain) Information Request No. 20 – Condition 26 Burnaby Mountain Tunnel option – design, construction, and operation
In References ii) and iii) Trans Mountain provided additional information to support Trans Mountain’s interpretation of these regulations.
The Commission notes that the requirements of Condition 26 are not tied to any particular regulation and that Condition 26 stands independent of any regulations. The Commission further notes that Trans Mountain to date has not filed a Tunnel confined space entry procedure, as required by Condition 26. Instead, in Reference iv), Trans Mountain provided the Tunnel Entry Procedures which is not adequate to meet the requirements of the Condition.
Reference v) indicates that once the boring and lining is completed, workers will enter the tunnel to carry out construction work such as installation of pipe supports, welding and coating activities. The Tunnel Entry procedure that Trans Mountain filed deals with a person’s initial entry into and exit from the tunnel and does not discuss entering the tunnel when these activities are undertaken, as some of these activities inside the Tunnel have the potential for the generation of harmful airborne contaminants that may need to be considered when entering the Tunnel. Nor does the procedure address potential complications in delivering first aid, evacuation, rescue or other emergency response services as a result of the internal configurations of the Tunnel.
The Commission requires Trans Mountain to file a Tunnel confined space entry procedure, and expects the procedure to be a comprehensive and stand-alone document which includes the necessary information for a person to enter and conduct work safely in the Tunnel environment.
Request:
Provide a Tunnel confined space entry procedure which includes, but is not limited to, the following:
• Roles and responsibilities of personnel (e.g., Owner, Prime Contractor, Sub Contractors, Emergency service workers, etc.); • Training requirements; • Hazard Assessment and Identification process(es); • Permit Requirements (e.g., confined space); • Safety requirements - operational procedures which describe the hazards and define the rules and conditions under which persons will be permitted to enter to confined spaces; and • References to Emergency and rescue procedures.

Trans Mountain Expansion Project Tunnel Entry Procedures
Tunnel Entry Procedures
1. SCOPE
1.1 To ensure the safety of persons either working in or visiting the tunnel, strict procedures are to be implemented. These cover procedures for the initial entry into the tunnel, location of safety equipment, exit procedures and the actions to be taken in the event of an emergency evacuation.
This procedure is not only intended for the regular workforce and visitors but is to be used for all persons who may at some stage enter the tunnel. Occasional visitors will only be allowed into the tunnel when accompanied by an experienced person, however the visitor will still need to be aware of all the hazards associated with the tunnel environment. This procedure is to form part of an orientation for all first-time visitors.
2. DEFINITIONS
2.1 Entry Procedure - Bullet point list to be posted at the tunnel entrance, indicating the steps to be taken on entry and exit into the works.
2.2 Notice board - Board located at the entrance of the tunnel, housing tag boards, mailbox for contraband, tunnel location plans and notice board for posting safety information.
2.3 Tag Board - Series of numbered hooks to hang brass tags, indicating number of persons currently within the tunnels. One tally board will be provided for each tunnel.
2.4 Contraband - Any materials not permitted into the tunnel, such as Tobacco, matches and cigarette lighters.
2.5 Muster Point - Location for all persons to congregate in the event of an emergency. Location detailed on access drawings.
2.6 Visitor Orientation - Checklist of specific instructions to be given to visitors to the Tunnel. Visitors will be accompanied at all times, therefore only a short orientation will be required.
2.7 Owner – Trans Mountain Pipeline ULC with the role and responsibility of oversight of this plan.
2.8 Segment Manager – KLTP manager for the Burnaby Mountain Tunnel with roles and responsibilities that include monitoring Subcontractor for adherence to the Project and Site Specific Plans, and that all operations have detailed execution plans, and ensure that supervisors understand and enforce safe work procedures, and lead all accident (and near miss) investigations involving people or equipment.
2.9 Project Manager – Subcontractor manager and may include any person nominated by the Project Manager to act on his behalf, by default will be the most Senior member of Subcontractor’s staff currently on the Site. The Project Manager’s duties and responsibilities are defined in Section 1.5 – Subcontractors of the KLTP Lower Mainland Project Specific Safety Plan (TMEP Document #01-13283-GG-0000- HS-HSE-0001 Revision 3)
Page 1 of 4 Trans Mountain Expansion Project Tunnel Entry Procedures
2.10 Experienced Person - Person trained in tunnel orientation and self-rescue procedure and has previous tunnel experience.
2.11 Indoctrination – A Project Safety Orientation as defined by Section 1.6 – Training of the KLTP Lower Mainland Project Specific Safety Plan (TMEP Document #01-13283- GG-0000-HS-HSE-0001 Revision 3)
3. PROCEDURES
3.1 A. Tunnel Entry.
3.1.1 Prior to any person (visitor or employee) going below ground, they must first complete two orientations. The first orientation process is the project wide Indoctrination and generally includes 3 sections; 1) the KLTP safety, environment, cultural awareness and security specific expectations 2) the Trans Mountain safety, environment, cultural awareness, and the security expectation and the overall Trans Mountain Canada safety videos and 3) a review of the Trans Mountain Code of Conduct. Secondly, all employees will receive a tunnel specific orientation detailing specific hazards relating to the tunnelling works prepared in accordance with Section 2.16 – Field Level Hazard Assessment KLTP Lower Mainland Project Specific Safety Plan (TMEP Document #01-13283- GG-0000-HS-HSE-0001 Revision 3). For persons required to work in the tunnel, full Indoctrination will be required as defined by the KLTP Lower Mainland Project Specific Safety Plan, however others may require access from time to time on a visiting only basis. A tunnel visitor orientation is to be used for these persons that will identify the hazards associated with the particular visit only.
3.1.2 Any person, entering site must report to the site offices before proceeding onto site. This will be to receive site orientation training and be allocated the relevant brass tags. Visitors will be required to sign the site logbook, and a release from liability statement.
3.1.3 Prior to any entry into the tunnel, the ventilation system must be working. In the event of a prolonged absence of ventilation from the tunnel, the fans must be run for a period of 15 minutes prior to entry.
3.1.4 Once ventilation has been established, checks must be carried out for dangerous gases. This will be done by reviewing the real time data from the TBM, or by means of a gas monitor inside the tunnel for a period of 5 minutes prior to entry. The handheld gas monitor is required post TBM operations.
3.1.5 For welding and coating operations, a bulkhead will be installed at the Westridge Terminal and the fan settings adjusted to supply the minimum required air movement from Westridge to Burnaby. This will maintain the fumes from welding and coating flowing towards Burnaby and away from the work.
3.1.6 Materials – The only known hazardous material that may be used in the tunnel could be gasses in cylinders (e.g. propane) for torching (if needed during TBM operations) and pre- heating of the weld joints. If combustible gases are required for torching, it will only be taken in the tunnel in small quantities and taken in just for the work and then removed out of the tunnel. Propane tanks for pre-heating weld joints will be removed from the tunnel during non-work hours or when empty, and shall be stored downwind of the hot work. Hazardous materials must be handled in accordance with Section 6.8 – Workplace
Page 2 of 4 Trans Mountain Expansion Project Tunnel Entry Procedures
Hazardous Materials Information System of the KLTP Lower Mainland Project Specific Safety Plan (TMEP Document #01-13283-GG-0000-HS-HSE-0001 Revision 3)
3.1.7 Confined Spaces – Confined Spaces shall be handled in accordance with Section 7.9 – Confined Space of the KLTP Lower Mainland Project Specific Safety Plan (TMEP Document #01-13283-GG-0000-HS-HSE-0001 Revision 3)
3.1.4 On entry to the tunnel, the following procedures apply:
3.1.4.1 Look for name on printed sheet on tag board. Move your tag from the ‘out’ nail and place onto the ‘in’ nail. Your second tag should be retained on your person. In the event of your name not being present, you will be issued with 2 visitor tags. Place one tag onto the ‘in” nail and retain the second.
3.1.4.2 Check that ventilation is running, and gas monitoring is in place. It is the duty of the Shift Engineer to carry out the gas monitoring below ground at the start of the shift. A record of the days check will be maintained in the site office. If in any doubt do not enter.
3.1.4.3 Entry into the tunnel will be generally by foot. Once the tunnel is excavated to a longer distance a custom-built man car will be used to enter/exit the tunnel.
3.1.4.4 Walking through the tunnel involves walking along the centre of the tunnel, special curved ties are provided, which allow a clear walkway through the tunnel.
3.1.4.5 Checks are to be made before entry as to the location of the train. Persons should not enter the tunnel whilst the train is still outside of the tunnel. Wait in the portal until the train has left for the tunnel face. No entry is to be made into the tunnel without clearance from this operative.
3.1.4.6 For riding on the locomotive, passenger seats have been provided on each locomotive. No more than one passenger per seat is allowed to travel on the locomotive and all persons must be seated. No persons are to talk to the driver whilst the locomotive is in motion.
3.1.4.7 When walking in the tunnel always be aware of the train’s location. Should the train start to exit while walking into the tunnel, be prepared to stop and face the train and make your way to a step up. Step ups, consisting of an elevated platform at the side to the tunnel are provided at approximately 50-100m intervals. The train is able to pass while a person is standing on the step ups. Within the tunnel machine access is provided along the walkway on the side of the machine, access can be made beneath the gantries, however this area is not a designated walkway should only be used for trained personnel required to be in there.
3.1.4.8 On arrival at the place of work (Tunnel Boring Machine, Welding or Coating Joint), the train will come to a stop adjacent to the rear of the work area. Do not exit until the driver has given the say so.
3.1.4.9 Once at the place of work, ensure you are aware of self-rescue set, fire extinguisher and first aid kit locations. Report any damage or deficiencies.
Page 3 of 4 Trans Mountain Expansion Project Tunnel Entry Procedures
3.1.4.10 When leaving the TBM gantries, the belt man is to be informed. For the pipe installation operation, inform the Foreman.
3.1.4.11 On leaving the tunnel you must remove your brass from the brass board. Failure to do so could result in rescue teams deployed to searching for a person who has left the tunnel.
3.1.4.12 Visitors are to return to the office to return self-rescue sets, and to sign out.
A condensed entry procedures checklist, together with a list of site rules will be posted in the brass shed and on other notice boards. Tunnel safety systems, entry procedures and other information will be continuously updated as required.

Project management will establish and participate in the JHSC activities and McNally’s QHSE department will facilitate the activities of the JHSC committee.
2.2 DETAILED EXECUTION PLAN
Proper work planning ensures our projects are built safely, on budget and on schedule. Detailed Execution Plans (work plans) are required to ensure site crews are organized and ready to begin work. A high-level work plan will be developed under the supervision of the Project Engineer in collaboration with the superintendents and foremen, and will be submitted to KLTP for comments. At field level, task specific work plans will be created by the Field Engineer / superintendent that will be completing the work.
All work plans must be reviewed and approved by the Construction Manager, Superintendent, Quality Manager, Environmental designate and Safety Manager.
It is the foreman's responsibility to ensure the proper execution and communication of the work plan with his/her crew. The foreman is responsible for ensuring that the crew understands the expectations of their work performance and execute tasks to the approved plan without major deviations.
If a situation arises where an operation requires a major deviation and can not be executed as written, the operation must be shut down and the foreman will immediately inform the superintendent. Work plan must be revised, documented and reviewed prior to commencement of the work.
It is imperative that the concept and use of detailed execution plans also be instilled into our Subcontractors executing work in the field. The Construction Manager and supervisor will ensure that detailed execution plans are developed and approved for the subcontracted scope of work to be executed on the project.
The Detailed Execution Plan will include, as a minimum, the following:
• Step by step instructions of the work
• Access/Egress Plan (if needed)
• Hazard & Mitigation Matrix
• Material Staging/Handling Plan (if required)

A hard copy of the report will be kept in the supervisor’s onsite trailer for the duration of the project to be available for inspection by an officer, project management or any personnel on the project. The underground record will be retained for 5 years after completion of the project.
2.10 SAFETY STAND DOWNS
When an emergency, urgent systemic problem or a near miss has been identified, the affected group will be required to have a safety stand down. The scope of the safety stand down is to identify and educate the affected personnel on what happened and an appropriate update on the investigation being conducted. The Project Manager and/or Safety Manager is to assess the personnel to identify whether critical stress debriefing is required.
A safety stand down may also take place if safety performance is below expectations. This may give management an opportunity to re-set safety expectations for the project. In the case of an urgent systemic problem arising, a safety stand down will be used to bring the problem forward to all the affected employees and to develop an action plan, with the input of the employees, in order to solve the problem and prevent reoccurrence.
The project manager or management that is higher on the Contractor Organization Chart has the authority to initiate a Safety Stand Down. Typically, the decision to have a stand down will be discussed by the Sponsor and the Project Manager in conjunction with a KLTP and/or Trans Mountain representative.
2.11 SUBCONTRACTOR SAFETY PROGRAM
All subcontractors will receive and review this safety plan, along with KLPT’s safety plan, and develop a suitable Health and Safety Plan for their work that will meet or exceed the requirements herein. Each subcontractor will:
1. Submit a copy of the Tables of Contents for their Safety, Health and Environment policies and procedures manuals for review and may be required to submit their full safety plan.
2. Submit documentation (in the form of a risk reduction plan) describing how their company addresses and complies with Contractor's safety policy, values, philosophy and Safety Management System guiding principles and core functions.
3. Subcontractors adhere to program requirements in sections 1-2.
Share their WCB rates for the past three years and provide a COR Letter. List all issued and upheld citations or fines issued to them from local, provincial and federal government agencies in the previous three years. If none have been issued, they will be asked to state that this is the case.
The Subcontractor’s Health and Safety Plans must be approved by McNally’s site Safety Manager prior to them starting any work on site. The program must include a Job Hazard Analysis identifying the process and controls that will used to eliminate or control all hazards directly associated with their work.
Any subcontractor whose work activity requires Regulatory Authority approval shall submit their plans and procedures in accordance to WorkSafeBC OH&S Regulations to the McNally Site Safety Manager. Submittals to Regulatory Authority will be completed by Trans Mountain. Any subcontractor who fails to meet pre- qualifications and or provide a Pre-Job Hazard Assessment or JHA is subject to disciplinary actions by McNally.
All Subcontractors are required to go through the Contractor safety orientation training which includes the
Project Specific Safety Plan Rev. 0 March 2018 Page 28 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Trans Mountain orientation videos.
All incidents, including near misses and occurrences involving personal injury or property damage, must be immediately reported to McNally and investigated by the Subcontractor in collaboration with McNally and KLTP. McNally expects the root causes of incidents to be determined and actions to be taken to prevent future similar incidents. McNally reserves the right to request copies of Subcontractor incident reports, investigation findings and to conduct further investigation and analysis as warranted. Root cause investigations are required for all recordable injuries and high-potential near misses at a minimum. Further root cause investigations may be requested by the Contractor management or Subcontractor supervisors.
2.12 RISK ASSESSMENT & CONTROL
As part of the project start-up process, the Site Safety Manager in conjunction with site staff identifies the project hazards, conducts a risk assessment and identifies controls using the Hazard Identification, Risk Assessment & Controls (HIRAC) tool. For each activity, a risk rating is assigned and the necessary operational controls are required to prevent or minimize the risk identified.
Hazards are assessed and ranked using a Risk Assessment Matrix. The Matrix helps to identify the risk potential severity and probability of that hazard so the required level of control to manage the risk to a level as low as possible can be determined, see Figure 2 below.
Figure 2: Risk Assessment Matrix
Refer to Appendix A for the project specific risk assessment.
Project Specific Safety Plan Rev. 0 March 2018 Page 29 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Hazard Elimination and Hierarchy of Control
When a hazard cannot be eliminated, the hierarchy of controls is to be implemented, listed in the preferred order:
A number of these options may be considered and applied individually, or in combination, to ensure that exposure to hazards is reduced to an acceptable level. If a hazard cannot be eliminated or mitigated effectively, all personnel involved shall be informed of the hazard and be given the necessary precautions to avoid any incidents.
2.13 WORKPLACE HAZARD ASSESSMENTS AND JOB HAZARD ANALYSIS
Tasks that expose workers to personal risk are subject to special planning. For these tasks, management, the Joint Health & Safety Committee, Health & Safety Representative, and affected workers, as applicable, may complete a job hazard analysis. The analysis and precautions to control or reduce the hazard must be communicated to workers prior to performing the tasks, and during safety meetings and worker orientation sessions.
McNally will utilize three forms of Job Hazard Analysis (JHA) to aid in the recognition and control of workplace hazards. All three hazard assessments assist in recognizing hazards of various degrees and at different points in the construction phase. McNally will adopt these forms for the Burnaby Mountain Tunnel.
HAZARD IDENTIFICATION, RISK ANALYSIS & CONTROL (HIRAC)
A Hazard Identification, Risk Analysis and Control Analysis is conducted prior to project start up to identify work activities being contemplated for potential health and safety hazards.
The completion of this hazard assessment includes input and review by members of management, supervisors, on site Safety Manager, JHSC and the safety department.
JOB HAZARD ANALYSIS (JHA)
1. Evaluate and identify hazards or potential causes of accidents in operation or steps in an operation,
Project Specific Safety Plan Rev. 0 March 2018 Page 30 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
2. Develop solutions to eliminate or control these hazards,
3. Incorporate the solutions and controls developed into the operation work plan,
4. Communicate the hazards and planned controls to the project team and workforce, and
5. Document and incorporate changes to the planned controls and hazards identified as the work progresses.
A JHA will be developed for major operations. A preliminary list is as follows and will be updated as the work progresses:
• Site setup ➢ Clearing site ➢ Site utility installation ➢ Utility Relocation ➢ Jobsite trailer installation ➢ Fencing ➢ Site electrical installation • Instrumentation installation • Portal installation (third party HIRAC) ➢ Secant pile installation ➢ Excavation ➢ Shotcrete and soil nail installation • Tunnelling ➢ Unloading and assembly of TBM ➢ Launch frame installation ➢ Tunnel entry procedures ➢ TBM launch ➢ TBM mining and precast installation ➢ TBM maintenance ➢ TBM head maintenance / confined space ➢ Hyperbaric / compressed air interventions ➢ TBM retrieval and demobilization • Steel Carrier Pipe installation ➢ Unloading, handling and positioning ➢ Welding ➢ Coating repairs ➢ Pipe fit-up ➢ Hyperbaric, Welding and Coating Testing • Tunnel backfilling • Portal backfilling • Final Site Restoration
PRE-TASK ANAYSIS AND RISK REVIEW
An industry recognized best practice that is both practical and supportive requiring all hazards to be identified to a worker. It supplements formal hazard assessment and job planning strategy by providing a “here and now” assessment of the work place.
Project Specific Safety Plan Rev. 0 March 2018 Page 31 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Pre-task talks are designed to communicate all hazards and will be carried out at the start of each task, when the conditions or scope of work has changed and when a worker has been added or removed from the task for any reason. This process requires participation of the front line supervisor/foreman and the work crew. It assists in the identification of hazards or potential hazards related to a task and will be referenced in accident or incident investigations, hazard control development and task control planning situations.
The front line supervisor/foreman will lead the pre-task process. It is their responsibility to plan the work, ensure all hazards are identified and that proper equipment, processes and personnel are in place to perform the task safely and efficiently.
Workers are responsible and accountable for participating in this process on an active and ongoing basis. They are expected to discuss hazards and controls with the front line supervisor/foreman to ensure that the work can be done safely. The worker is responsible to advise the immediate supervision of a change of work that would facilitate a new pre-task assessment. They will acknowledge their participation in the process by initialing the pre-task attendance sheet.
2.14 INCIDENT REPORTING AND INVESTIGATIONS
The accident/incident investigation system is a resource used by our management and safety professionals to address loss events (accidents and incidents) which result in or have the potential to result in personal injury, ill health, property damage, environmental impact, interruption of normal activities or an emergency.
Any loss shall be investigated promptly and thoroughly. This system requires that workers report all loss events, as outlined in their orientation, for investigation to their supervisor immediately. The following are examples of loss that require immediate attention:
• Injuries (non-disabling and disabling)
• Occupational illness
• Fatalities
• Fires and explosions
• Property damage
• Environmental harm
• Third party complaints
• Near misses
Upon the occurrence of an incident, the employee(s) involved must immediately inform their supervisor of any applicable critical injuries, lost time, medical aids, first aid, environmental impacts, or property damage. The supervisory personnel shall complete the Incident Notification Form (QSHE-F-01-a) and submit to the QHSE department, and KLTP within 24 hours of the occurrence (verbal notification within 2-8 hours, see SSERP for reporting times). As well, an Incident Investigation Form (QHSE-F-01-b) relating to the incident needs to be submitted to the QHSE department, and KLTP within 7 days, at which time the QHSE department shall review and record the Incident Investigation Form into the QHSE Database. The QHSE department along with the Supervisory Personnel shall determine if further investigation is required. If required, a Corrective Action Request (CAR) report shall be generated. See Incident Reporting and Investigation (QHSE-PRO-70) for
Project Specific Safety Plan Rev. 0 March 2018 Page 32 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
McNally reporting and investigation details.
As well, all accidents/incidents, modified work, medical air and loss time injuries shall have the appropriate report completed and forwarded to KLTP.
Accident Investigation Teams shall include the involved worker, any witnesses and the foreman involved, as a minimum. Additional members may include but are not limited to, Sr. Management, H&S Representative, McNally Senior H&S personnel, JHSC, KLTP safety representative and a Trans Mountain safety representative. All incidents shall be investigated as per McNally’s Accident/Incident Investigation standard in the corporate H&S program. McNally Accident Investigation Team will also assist KLTP and Trans Mountain with any accident investigation involved with their work if required.
All subcontractors will conform to the same standard of reporting and investigation and shall insure that corrective actions are implemented in a timely manner.
Near Miss Reporting
The Near Miss form will be used to report near misses and capture the following information:
• Date (of the near miss incident)
• Time
• Location
• Description of near miss
• Action taken at the time
Once the near miss report is filled in, it is forwarded to either the H&S Advisor or to the appropriate foreman, who will forward it to the H&S Advisor. Once the H&S Department has the near miss report the appropriate level of investigation and corrective and preventative actions shall be established.
2.15 COMMUNICATION
Safety Bulletin Boards are an excellent communication standard for communicating major accident/incident announcements, legislative bulletins, safety audits, WorkSafeBC posters (mandatory), NEB Notices or information, operating experience, hazard alerts and other important communications. The Project shall maintain safety bulletin board(s) in the Sites Offices, First Aid Trailer and conspicuous location(s) where all workers have regular access to the Safety Boards.
If an incident occurs, project manager will inform KLTP within 30min via a face to face communication or a phone call if necessary. For hazard identifications and safety related information sharing; this will occur in daily pre-task instruction meetings, weekly safety meetings or informally through face to face communication between McNally and KLTP personnel.
External communications procedure will depend on the nature of the safety concern. McNally will adhere to the following:
• McNally will not have any Press releases • Communications with family members - The project manager, together with the Human
Project Specific Safety Plan Rev. 0 March 2018 Page 33 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Resource Manager, will make arrangements with the RCMP to jointly notify the closest family relative in the event of critical injury or fatality to an employee working at Westridge or Burnaby Terminal. • McNally and its employees will not have any contact with media members and will direct the media to the [email protected] website for further information as it becomes released. Media contact cards will be given out, see section below.

Failure to provide consent may result in disciplinary actions, up to and including discharge.
Project Specific Safety Plan Rev. 0 March 2018 Page 36 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
An employee may report to work while using prescription or non-prescription drugs providing they are taking the drugs as prescribed by their doctor or according to the manufacturer, and the drugs do not adversely affect their ability to work safely and the employee informs their immediate supervisor of the side effects associated with the drugs they are taking.
The McNally Drug and Alcohol policy shall be enforced on this tunnel project to ensure that all workers and staff are fit for duty. The policy includes:
• Based on the safety sensitive nature of our work, and the company’s obligation to provide a safe workplace, it is McNally’s expectation that all Employees come to work fit for duty.
• McNally will not tolerate anyone attending work under the influence of illicit drugs or alcohol.
• McNally Employees should not consume alcohol, illicit drugs or prescribed drugs that may affect fitness for duty during their shifts, including lunch and rest breaks.
• Any Employee suspected of being unfit for work as a result from the use of alcohol, illicit or prescription drugs will be subject to McNally’s Drug and Alcohol Testing Procedure, HR-PRO-04.
• At McNally sponsored social events where alcoholic beverages are made available, the company expects employees to consume responsibly and to not become impaired.
• Where an employee has been prescribed drugs, the employee must notify their supervisor. If there is concern relating to fitness for duty, an investigation will be conducted.
• Employees with concerns relating to use of substances are to seek assistance and notify their Supervisor or Human Resources immediately. An Employee with an alcohol or drug dependency problem may be entitled to accommodation based on disability under the Human Rights Code.
As well, McNally will comply with the intent of KLTP’s Drug and Alcohol Policy.
Application of the Drug and Alcohol Program
Supervisors will receive basic training in their supervisory training on how to detect signs that a worker is not fit for duty.

Project Specific Safety Plan Rev. 0 March 2018 Page 37 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
keep this information in confidential personnel files separate. These records and information may be disclosed to:
• Applicants and employees or any other third party designated in writing by the employee.
• A substance abuse professional, physician or other health care provider responsible for determining:
o An employee's successful participation in or completion of, any and all evaluations, counseling, employee's ability to safely perform his or her job.
o The treatment and/or rehabilitation program(s).
Supervisors are on a need-to-know basis, where relevant to McNally’s defense in a grievance, arbitration, administrative proceeding, lawsuit or other legal proceeding, or as required or otherwise permitted by law.
3.4 NEW AND YOUNG WORKERS
McNally will adhere to KLTP’s Short Service Worker Program. All workers who are new to the Contractor work site will be given a green sticker to wear on their hard hat. These workers will wear the green sticker on their hard hat for 30 days, at which time they will perform the 30-Day Follow-Up. Upon successful completion of the follow-up, they will switch to a black sticker which signifies that they have graduated the short service worker program. This 30-day period is intended to give the worker mentoring time to learn the safety policies and procedures of the project.
The following are additional guidelines in implementing the Short Service Worker Program:
• Workers will be notified of tasks that they are not authorized to perform (e.g. operate certain types of equipment) and environments that a short service worker is not authorized to work within (e.g. working alone).
• The short service worker program will be incorporated to focuses on improving the knowledge and skills of the new worker, ensuring that they are properly trained for any assigned tasks.
Superintendents must ensure that new workers are enrolled in the projects short service worker program and remain enrolled until they complete the 30-day follow up and:
• Are competent in the basic skills required to do safe work
• Understand and are committed to our safety culture
Supervisors must ensure that short service workers:
• Are assigned work they are competent in
• Are paired with experienced workers
All workers must:
Provide instruction, coaching and additional safety precautions for short service workers, to ensure their safety.
Project Specific Safety Plan Rev. 0 March 2018 Page 38 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Not request a short service worker to do new tasks they are not trained for or competent in
• During the short service worker process it may be identified that a worker can graduate to the black sticker earlier and it may also be identified that a worker needs more mentoring before they graduate to the black sticker.
30-day follow-up
The segment construction manager or designate will meet with the new craft workers to re-emphasize the safety program and solicit information from them on how they feel about the safety of the workplace. At this point a 30 day follow up will be administered. Successful completion of this follow up will qualify the employee for the black sticker.
Safety Education Programs
Contractor will establish and implement safety education programs designed to stimulate and maintain the interest and active participation of all personnel involved with the project. These programs will include:
1. Safety meetings and safety communications
2. Use of incident trends and causal analysis to preclude reoccurrence of similar incidents
3. Use of proper work procedures, personal protective equipment, and mechanical guards
Safety instruction will include:
• Hazard Recognition Training (within first 60 days of work)
• Factors of Risk Tolerance (within first 60 days of work)
• Job hazard analysis (Refresher done with 30-day follow up)
• Fall protection (As required by workers position)
• Confined space entry (As required by workers position)
All superintendents who supervise employees that need confined space, fall protection or elevated work platform training also must have these trainings completed. If directing work without these courses completed, a CSA must visit their specific operations daily until the superintendent has the courses, and receive a briefing about these activities from the CSA. A superintendent is not permitted to direct work in these categories for more than a month without the required trainings.
3.5 MEDICAL CARE
McNally will ensure that employees have access to first aid supplies in case of illness or injury. McNally will maintain the required first aid materials at both the Westridge Portal and Burnaby Portal sites in accordance with the British Columbia OH&S legislation.
First aid will only be administered by a trained and authorized first aider. A list of qualified first aiders as well as their certificates will be maintained and located as described in the Site Specific Emergency Response Plan (SSERP).
Project Specific Safety Plan Rev. 0 March 2018 Page 39 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
First aid treatments will be documented by the safety manager. Notification and reports will be provided to McNally’s QHSE department, KLTP, KMC, Trans Mountain and local authorities as described in the SSERP.
An adequately supplied First Aid station will be maintained at both the Westridge and Burnaby Portals. A dedicated first aid trailer will be located on the Westridge Portal Site and will include all first aid equipment and supplies including but not limited to; first Aid Kits, stretchers, fire extinguishers, first aid logs/record and mine rescue equipment. The Burnaby Portal area will be equipped with the same medical supplies excluding mine rescue equipment and located in the supervisor’s trailer. Medical supplies will be:
• kept clean and dry • checked on a regular basis for expiry dates and updated as needed • maintained in quantity for the number of people on site
Any company personnel issued a McNally Construction truck must keep one small first aid box in their truck with the supplies replenished/replaced as required.
During peak construction times on the project KLTP will have a full-time nurse employed which will be available for use by McNally.
In case of an employee experiencing illness or injury requiring outside treatment, a safety staff member will always escort the employee to outside medical attention, and will maintain contact with the project safety manager as to the status of the injured or ill employee. For non-occupational first aid, the ill or injured employee can be escorted by an employee of their choice. In minor non-occupational cases the injured or ill worker can seek medical attention on their own after clearing it with the safety manager.
The location and contact numbers for local hospitals and preferred medical clinics will be posted at both sites. Please refer to the SSERP for more information on medical care and emergency information.
3.6 SAFE DRIVING
The following guidelines apply to the general use of all company vehicles, whether leased or purchased.
Authorized personnel will operate company fleet vehicles only. Personnel driving project vehicles are required to conduct themselves with the highest degree of courtesy and professionalism, both in their operation of the vehicles and in any dealings, they have with the public.

Project Specific Safety Plan Rev. 0 March 2018 Page 41 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Cell phone or camera usage in the terminal and tank farm areas will require a permit from KMC operations or an intrinsically safe phone or camera must be used.
Crafts working underground are not permitted to use cell phone unless emergency occurs. When using the cell phone underground, make sure to stay in a safe place, for example, lean on the fence or structures that are away from moving equipment.
There will be no use of cell phones while operating a company vehicle including hands free devices within the project limits.
Texting while driving is strictly prohibited. Drivers must pull over, turn on the vehicle's four-way flashers, and exercise caution. Staff employees with company-supplied phones must also refrain from using them while walking around the work site.
Cell phones are not permitted to be used while operating equipment.
Failure to abide by this policy will result in disciplinary action, which could involve loss of driving privileges, up to and including termination.
3.8 SMOKING IN THE WORKPLACE
Smoking/vaping is prohibited in all indoor areas of a workplace. These areas include the underground tunnel, site office trailers, lunchrooms, washrooms, tool- cribs, warehouses, vehicle maintenance areas, operations buildings, vehicles and equipment.
Smoking/vaping will not be permitted indoors or in areas within 3 metres of a building door way or otherwise enclosed area. When working within Brownfield, smoking/vaping will also not be permitted in Kinder Morgan’s restricted area.

Matches or uncovered and trigger-type lighters are not allowed.
Anyone found in contravention of this policy may be subject to disciplinary action up to termination.
3.9 DISCIPLINARY ACTION PLAN
McNally believes in a corrective and progressive disciplinary program. The goal of this program is to provide supervision with a tool to educate workers in areas where inappropriate, repeated, willful or inexcusable contraventions of safety policies, practices and business ethics have taken place.
The steps of Corrective Disciplinary Action will be as follows:
• When disciplinary action is required the immediate Supervisors will consult with either the Human Resources Manager for behavioural contravention or the QHSE Manager for safety or Environmental offences and claim disputes, in order to ensure consistency and fairness in the corrective disciplinary process. Prior disciplinary record shall be verified with the Human Resources Manager before finalizing corrective disciplinary action.
• The Supervisor, Human Resources Manager and/or QHSE Manager will determine the corrective
Project Specific Safety Plan Rev. 0 March 2018 Page 42 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
disciplinary action depending on the severity, and/or previous discipline records. Some actions are considered serious enough to warrant severe disciplinary action up to and including termination for cause for a first offense. The corrective disciplinary action can be taken depending on the circumstances and the mutual decision of the Supervisor, Human Resource Manager and/or QHSE Manager.
• All disciplinary actions are to be recorded on a Corrective Disciplinary Action Form
Examples of health and safety violations where any employee will be disciplined or subject to discharge could be:
• Violation of health and safety rules, policies, or procedures
• Violation of zero tolerance policies
• Stealing or wilful destruction of company property
• Violence, harassment, horseplay or disorderly conduct on company property
• Coming to work under the influence of drugs or alcohol or bringing these items to work
3.10 WORKING ALONE
Prior to working alone or in isolation, the worker must identify the surrounding hazards and eliminate the hazards or when it is not reasonably practicable to do so, then to reduce the risk from the hazard.
No workers are permitted to work underground (including the tunnel) alone for any reason.
Certain site activities prohibit personnel from working alone due to the nature of the hazards and emergency response. (i.e. confined space)
Workers who will be working alone shall be given a means of communication (i.e. radio) to contact supervision when required. Contact intervals shall be no less than once every two hours.
In the event of a "failed check in", meaning that contact has not been made, the supervisor or designate shall immediately attempt to contact the worker by radio, then in person. If the person cannot be found, notify Management for potential notification of security, safety stand down for a mass search and or summoning the police department if required.
3.11 FATIGUE MANAGEMENT
Fatigue is a state of being tired. It can be caused by long hours of work, long hours of physical or mental activity, inadequate rest, excessive stress and combinations of these factors. The signs, symptoms and affect fatigue has on workers varies from one person to the next, however, fatigue may affect the individual worker’s ability to perform mental and physical tasks.
Fatigue Management System (FMS)
The purpose of the FMS is to ensure that management, supervisors, and workers understand what fatigue is, how to recognize it, and how to proactively deal with is in the workplace. An effective FMS will include awareness of and response to fatigue issues in the workplace.
Project Specific Safety Plan Rev. 0 March 2018 Page 43 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
It is the policy of McNally that it will train to the best of its ability, all management and supervisory personnel to recognize and respond to the signs and symptoms that might impair the worker’s performance due to fatigue. The supervisor will be responsible to make changes to work requirements if fatigue impairment signs are evident. All concerns should be communicated to management and changes documented, reviewed and followed-up. It is the responsibility of all workers to conduct themselves at work and in their lifestyle in such a manner that they present themselves each day for work in a fit and unimpaired/unfatigued condition.
Roles and Responsibilities
Management
• To ensure the FMS is implemented throughout the company
• Provide the necessary information about fatigue
• Provide instruction and training
• Communicate employer expectations
• Monitor the effects of extended work hours
• Support employees who are experiencing concerns with fatigue
• Assist and advise line supervisors
• Investigate and problems and/or concerns
• Inspect the workplace and review FMS with employees
• Review the FMS
Supervisors

• Be aware of the possible risks associated with extended hours and/or consecutive days of work
• Give workers as much notice as possible if extended hours are anticipated
• Observe and record how individuals respond to extend hours
• Recognize symptoms of fatigue
• Get feedback from individual crew members and the crew as a whole
Project Specific Safety Plan Rev. 0 March 2018 Page 44 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Take prompt action if a risk develops
• Relay information to and from management & employees
• Report any FMS problems, concerns and/or issues
Employees/Crafts
• Actively participate in FMS awareness
• Recognize symptoms of fatigue
• Promptly report any fatigue-related concerns
• Report any individual medical or personal situations which may influence fatigue

3.12 LIGHTNING ACTION PLAN
Overview
This guideline, will decrease the risk of an incident due to lightning. This Lightning Action Plan/Protocol is in place to notify and evacuate workers, on towers, tanks and in large open areas, to a safe location when they are at risk from a lightning threat. We are responsible to ensure our workers, at risk to the lightning threat, are aware of their Lightning Action Plan/Protocol.
Safe work locations must be identified as part of the plan, along with a means to notify workers and route them to those locations. An "All Clear" signal must be identified and should be considerably different than the "Warning" signals.
If Thunder is heard… The Lightning is…
5 seconds after a flash 1 mile away
10 seconds after a flash 2 miles away
15 seconds after a flash 3 miles away
20 seconds after a flash 4 miles away
25 seconds after a flash 5 miles away
Project Specific Safety Plan Rev. 0 March 2018 Page 45 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
30 seconds after a flash 6 miles away
35 seconds after a flash 7 miles away
40 seconds after a flash 8 miles away
40/30 Guideline
When there is 40 seconds or less (8 miles) from "flash to bang", then you are too close to the storm and need to implement the Response to Severe Lightning Storms plan immediately, located in the SSERP. Thunder takes 5 seconds to travel one (1) mile after the flash. The average length of a lightning bolt is 8 miles and the maximum distance you can hear thunder is as short as two (2) miles and seldom exceeds twelve (12) miles.
Wait at least 30 minutes after the last "flash to bang" before leaving the sheltered area.
3.13 EMERGENCY RESPONSE PROGRAM
An overall Site Specific Emergency Response Plan (SSERP) has been developed and will be posted in occupied trailers, the Site Safety Bulletin Board, and brass shack at a minimum.
This plan includes elements such as first aid station locations, emergency contacts, emergency medical locations, evacuation procedures, site warning systems (Alarms/Horns), and site specific emergency responses. Additional emergency plans may be required throughout the project (such as specific confined space plans) which will be developed and added to the SSERP.
3.14 EARLY & SAFE RETURN TO WORK PROGRAM
McNally will make every reasonable effort to rehabilitate and maintain the injured Worker’s income by providing an alternate comparable job, or suitable employment. An injured employee will be offered light duty work according to his/her abilities until the employee is completely capable to perform his/her original duties.
3.14.1 PROGRAM PRINCIPLES
• Effective management of a worker’s rehabilitation through a knowledgeable cooperative approach.
• Ensure that a worker receives prompt, effective, timely access to services required to enhance and facilitate their rehabilitation.
• Employees must be continually reminded of our back to work program. If they have an injury we will arrange for light duty work using their doctor’s guidelines.
• Each Supervisor will be responsible for accommodating the employee who is unable to perform his/her regular duties.
• Where a Supervisor is unable to provide suitable work, an attempt will be made to place the employee within some other division of the Company. (Contact the Safety Coordinator)
Project Specific Safety Plan Rev. 0 March 2018 Page 46 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
3.14.2 FUNCTIONAL ABILITIES FORM
As part of the workplace return to work Policy and Program, the “Functional Abilities Form” will be used along with a cover letter from the company. Employees must be instructed of the “Early and Safe Return to Work” policy during Employee Orientation. These forms must be kept readily available at all workplaces. Employees must be aware of these forms and the need to have them completed should they seek medical attention for a work-related injury.
3.14.3 MCNALLY CONSTRUCTION ‘INJURED AT WORK’ POSTER
Management at McNally Construction has created an “Injured at Work” poster. This poster was created to give an extra reminder of our “Early and Safe Return to Work” policy. It is expected that these posters will be posted around the workplace in several prominent locations. These forms can be obtained from the Safety Coordinator at Head Office. A few copies will be included in the Supervisors – “Job Set Up Kit” as well.
3.14.4 ABSENCES WHILE ON LIGHT DUTY WORK
Injury Related Absences
Employees performing light duty tasks will be excused from work for Doctor’s appointments related to the injury. Employees will be paid full wages for the time missed due to these Doctor’s appointments. It is expected that Employees will inform the Supervisor in advance of such appointments.
Non-injury Related Absences
Once the injured Worker has accepted light duty work, it is their responsibility to attend work as outlined in the light duty agreement. Should the Employee be sick or require to be absent for a reason that is non-injury related they must notify their immediate Supervisor. Whatever rules were utilized for absences prior to the Worker’s injury will be applicable for absences while on light duty work unless other arrangements have been made. Head Office will need a letter from the employee indicating that their absence was NOT injury related.
Should an employee sign a “Light Duty Agreement” indicating that he/she agrees to the terms of the offer and then misses three (3) days of work without notifying the Supervisor and following the above procedure; McNally Construction will consider these absences as notification that the Employee has quit our employment. A Record of Employment will be completed indicating the employee has quit.
4 GENERAL SAFE PRACTICES AND PROCEDURES
4.1 BOOM TRUCK
The importance of safe operation cannot be over emphasized. Carelessness and neglect on the part of Operators, job Supervisors and Planners, rigging Personnel and job site Personnel can result in their death or injury and costly damage to the boom truck or property.
Only qualified personnel shall operate the Boom Truck; those who are licensed for both truck and crane.
Hazard Precautionary Measure
Project Specific Safety Plan Rev. 0 March 2018 Page 47 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Overhead wires/Electrocution Maintain safe distance when working near overhead wires
Employees getting under or in the way of a lifted Stay clear of boom and load during operation. load Never walk underneath a suspended load.
Loadline coming loose Keep at least 3 wraps/rotations of loadline on the drum at all times.
Injury due to riding on crane loadline or hook This is not allowed at any time – never ride on hook, load or any device attached to loadline.
Tipover To avoid tipover, all outriggers must be properly extended on a solid, level surface
Truck tipover with load Always know your operational radius and the actual weight of the load being lifted.
Monitor weather and never utilize boom in extreme winds and weather.
Procedure
The operator must not operate the boom truck when he is physically or mentally unfit.
The operator is responsible for all operations under his direct control. When there is doubt as to the safety of an operation, the operator has the authority to stop the operation and refuse to continue until the unsafe condition has been corrected (i.e. hydro wires, insufficient light, bad weather).
Before starting the engine or engaging the power takeoff, the operator is to make sure that:
1. All daily inspection and maintenance has been performed.
2. All controls are in the off position
3. All personnel are in the clear.
The operator must not start crane movement unless a designated signal person is within his range of vision. The operator will obey an emergency stop signal at all times, no matter who gives it.
The operator is to perform the following operations before leaving the control station or the boom truck for any reason:
Project Specific Safety Plan Rev. 0 March 2018 Page 48 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Land any load.
• Lower the boom onto the boom rest if possible, otherwise, securely fasten the boom from movement by the wind or other outside forces.
• Move all controls to the off position.
• Park boom truck.
• Apply the truck parking brakes and chock the tires.
• Stop engine.
• Lock door of truck cab.
4.2 BULLDOZERS
Refer to the Occupational Health and Safety Act, Construction Regulations; sections 101(2) (3), 102, 103
Never attempt to operate a bulldozer unless you are fully qualified and authorized to do so.
Complete a circle-check around the machine.
Do not attempt to start or operate the machine from any position other than the seat provided.
To leave a bulldozer unattended:
1. Find a level, safe parking space (position bulldozer at right angles to a slope if you must park on a grade)
2. Lower attachments to ground
3. Place transmission controls in neutral and engage the transmission control lock
4. Set parking brake
5. Shut down engine (never leave machines unattended with the engine running)
Never let anyone ride on the machine
Operate at speeds slow enough to ensure complete control, at all times
4.3 CLEANING SOLVENTS AND FLAMMABLES
Cleaning solvents are used in the day-to-day construction work to clean tools and equipment. Special care must be taken to protect the worker from hazards that may be created from the use of these liquids. Wherever possible, solvents should be non-flammable and non-toxic.
The foreman must be aware of all solvents/flammables that are used on the job, and be sure that all workers who use these materials have been instructed in their proper use and the hazards they pose.
Project Specific Safety Plan Rev. 0 March 2018 Page 49 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Procedure
The following instructions or rules apply when solvents/flammables are used:
1. Use non-flammable solvents for general cleaning.
2. When flammable liquids are used, make sure that no hot work is permitted in the area.
3. Store flammables and solvents in dedicated storage areas.
4. Check toxic hazard of all solvents before use. (MSDS)
5. Provide adequate ventilation where all solvents and flammables are being used.
6. Use goggles or face shields to protect the face and eyes from splashes or sprays.
7. Use appropriate gloves to protect the hands.
8. Wear protective clothing to prevent contamination of workers' clothes.
9. When breathing hazards exist, use the appropriate respiratory protection.
10. Never leave solvents in open containers. Return them to closed storage containers.
11. Ensure that proper containers are used for transportation, storage and field use of solvents/flammables.
12. Where solvents are controlled products, ensure all employees using or in the vicinity of use or storage are trained and certified in WHMIS and that all WHMIS requirements are met.
4.4 COMPRESSED GAS
Always use care in handling all compressed gas cylinders. They must not be dropped, jarred or exposed to temperature extremes and should always have their contents properly identified.
The maximum capacity of compressed gas cylinders used underground must not exceed 10 kg (22 lbs.) and containers must meet the requirements of the Transportation of Dangerous Goods Act, 1992 (Canada).
Cylinders must have the valve cap or valve protection device in place at all times, except when in actual use or connected to a welding set. Cylinders are never to be rolled or lifted by the valve or valve cap. A suitable cradle is to be used for transporting.
Compressed gas cylinders, whether full or empty, are to be stored and transported in an upright position and secured so they cannot fall or be upset. They must be stored separate from fuel-gas cylinders or combustible materials (especially oil or grease) a minimum distance of 20 feet or by a 5-foot high non-combustible barrier. In addition, these cylinders must not be placed within 5 feet of an electrical outlet or where they might become accidentally a part of an electric circuit.
Never force connections that do not fit. Never tamper with the safety relief devices of cylinder valves.
Before the regulator is removed from a cylinder, the valve needs to be closed and all pressure released from
Project Specific Safety Plan Rev. 0 March 2018 Page 50 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
the regulator. Never use a leaking cylinder. Take the leaking cylinder outdoors and store away from any ignition source, notify the supervisor and deal with the situation immediately.
The recessed top of cylinders is not a resting place for tools.
A training course must be taken before working with propane.
Fire extinguishers must be provided at each storage area.
Oxygen
Oil, grease or similar materials can not be allowed to come in contact with any valve, fitting, regulator or gauge of oxygen cylinders. Also, oxygen shall never be used as a substitute for compressed air.
When an oxygen cylinder is in use, the valve should be opened fully in order to prevent leakage around the valve stem.
Acetylene
Acetylene cylinders are to be properly secured and always used, transported or stored in a vertical position. Cylinders shall be protected from sparks, flames and contact with energized electrical equipment.
An acetylene cylinder valve shall not be opened more than one and one-half turns of the spindle and preferably no more than three-fourths of a turn.
Employees shall not use acetylene in a free state at pressures higher than 15 psi.
All gas bottles must be stored outdoors.
Fire Extinguisher must be provided at each storage area.
4.5 CONFINED SPACE
A Confined Space, as defined by COHSR Part IX, is an enclosed or partially enclosed space that
(a) is not designed or intended for human occupancy except for the purpose of performing work,
(b) has restricted means of access and egress, and
(c) may become hazardous to any person entering it owing to
(i) its design, construction, location or atmosphere,
(ii) the materials or substances in it, or
(iii) any other conditions relating to it;
Confined spaces usually have:
o poor ventilation,
o the possibility of an oxygen deficient atmosphere, or
Project Specific Safety Plan Rev. 0 March 2018 Page 51 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
o the possibility of an airborne hazardous substance., or
o limited access and egress
Confined spaces within the tunnel or portal work may include, but are not limited to, if entry is required inside the TBM cutter head chamber (refer to section 5.2.12 for entry procedures), if entry is required to clean or unclog the cement and bentonite silos, and if entry is required inside the pipe.
The Burnaby Mountain Tunnel, Westridge Portal and Burnaby Portal will not be considered as confined spaces. As per the Canada Occupational Heath and Safety Regulations, Part XI, all three conditions above must be met to be classified as a confined space. The underground tunnel is designed and constructed with recognized codes and standards that contain provisions to make the space suitable for workers to occupy continuously, such as provisions for structural adequacy, entry and exit, ventilation and lighting. The codes, standards and requirements to ensure the health and safety of workers are contained under the Canada Occupational Health and Safety Regulations and WorkSafeBC Part 22, Underground Workings. The safety systems and procedures as described in the above regulations for tunnel construction in British Columbia are as stringent as confined space requirements.
In addition, the tunnel portals are not considered a confined space as they do not have restricted means of access or egress. At both Westridge Marine and Burnaby Terminal portals, the portal areas will be cut into Burnaby Mountain. At both portals, the ground elevation is the same elevation as the access road. Crews will be driven to site via the access road and enter the portal through a gated entrance. As the tunnel is at the same elevation as the portal, there is no special means required to access or egress the portal or the tunnel. The boundary between the portals and the Tunnel (classified as Underground Working) is the immediate entrance to the tunnel, or tunnel eye.
It is both the Supervisor and the Employee’s responsibility to ensure that safe working conditions for confined space entry are maintained. However, always assume that a hazard exists. It is the responsibility of any worker who must work in or around a confined space to follow this procedure and be aware of the associated hazards.
Entry into a confined space shall be avoided if possible, and astringently prepared for if necessary. Only employees properly trained in the hazards associated with confined space work shall be allowed to enter a confined space. Before entering a confined space, a confined space entry permit shall be obtained from the Constructor and posted.
4.5.1 HAZARDS IN CONFINED SPACE
Hazard Assessments must be conducted by a qualified person. Qualifications that are acceptable as adequate training and experience include: certified industrial hygienist, registered occupational hygienist, certified safety professional, Canadian registered safety professional, or professional engineer.
Hazards in a confined space can be broken down into two types; physical and atmospheric
Atmospheric hazards
Atmospheric hazards encountered in a confined space can include the following:
• Oxygen deficiency or enrichment
• Flammable liquids or gases
Project Specific Safety Plan Rev. 0 March 2018 Page 52 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Contaminants (dusts/fumes/toxic vapours and gases) that could pose an immediate threat to life, or interfere with a person’s ability to escape unaided from the space
Physical hazards
Physical hazards encountered in a confined space result from the nature and construction of the space. A space that is not normally occupied or is used for temporary access should be considered a confined space (when potential atmospheric hazards are also present)
Potential physical hazards in a confined space are:
• Limited access and egress
• Temperature extremes
• Electricity (including static)
• Moving parts or machinery
• Slips and falls within the space
• Hazardous chemicals
• Noise
Before any work is allowed in a confined space, it must be made safe for entry for the duration of the work. All existing and potential hazards must be evaluated and controlled. The standard confined space entry plan (for each specific space) must be reviewed by all affected personnel. And, the confined space entry permit is to be completed to the satisfaction of the Entry Supervisor; by a competent person.
Smoking is not permitted in any confined space at any time.
Examples of Confined Space Common Hazards
TBM excavation chamber Limited means of access and egress, poor lighting
Vessel Welding process may displace Oxygen and Create CO
Confined Areas Co-emitting internal combustion engines operating
(vaults, caissons, trenches) Nearby (CO heavier than air and could leak into the pit)
Utility Maintenance Holes Accumulation of toxic and/or combustible fumes from ducts entering the chamber.
Project Specific Safety Plan Rev. 0 March 2018 Page 53 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.5.2 RECOGNIZING A CONFINED SPACE
All spaces that have the potential to be considered a confined space must undergo an assessment (refer to Form “Recognizing Confined Spaces”). Most, if not all, of the confined spaces have undergone this assessment. Those spaces that have been assessed as confined spaces have had a specific entry plan created based on their characteristics and the type of work to be performed in them.
Each Confined Space Entry Plan is specific to the type of space and its location. For example, a confined space labelled as HAMI-CB-001-X, tells us that the space in question is catch basin number 1, located in Hamilton yard and is an Exclusive Confined Space (see below). Should an entry into that space be required the Confined Space Entry Plan for HAMI-CB-001 will be reviewed and the appropriate hazards controlled prior to entry. The Entry Plan will also detail the requirements for communicating intended work to other crews, rescue procedures and the equipment required to affect a rescue. Details for preparing for an entry to a specific confined space can be found in each spaces specific Confined Space Entry Plan.
4.5.3 TYPES OF CONFINED SPACES
There are two types of confined spaces that we will come into contact with, during the course of our work; Exclusive and Dependant confined spaces.
Exclusive
An Exclusive Confined Space is one that is;
• Partially or fully enclosed
• Is not designed or constructed for continuous human occupancy, and
• In which an atmospheric hazard may occur because of its construction, location or contents
These spaces must always be considered a confined space, no matter what type of work is done in them, because the hazards are inherent to the space at all times. These spaces are always to be considered confined spaces and the required procedures followed for their entry. For example, a ballast tank always has the potential to produce an oxygen deficient atmosphere, and will always be considered a confined space.
Methods for controlling the hazards found in Exclusive Confined Spaces are found in that space’s specific Entry Plan.
Dependant
A Dependant Confined Space is one that is;
• Partially or fully enclosed
• Is not designed or constructed for continuous human occupancy, and
• In which an atmospheric hazard may occur because of the work that is done in it
Sometimes it is the nature of our work that makes a space confined. For example, a storage compartment (not constructed for continuous occupancy) may not normally present a possibility for an atmospheric hazard to arise and is therefore not considered to be a confined space (under normal working conditions). However,
Project Specific Safety Plan Rev. 0 March 2018 Page 54 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
should maintenance require that the interior of that space be painted or welded, it would be considered a Confined Space because the possibility for an atmospheric hazard to arise is created, based on the activities within the space. If welding is required within that storage compartment the possibility for an oxygen depleted atmosphere arises, and the precautions set out in the space’s specific Entry Plan are to be employed.
Should hot work be performed within a space that is not designed for continuous occupancy, that space must always be considered confined.
What if the possibility for an atmospheric hazard can be eliminated?
If measures are implemented to completely eliminate the possibility that any atmospheric hazards may occur in a space, then the space is not considered to be a Confined Space. However, the elimination of the hazards must be complete and certain. For example, mechanical ventilation is a method to control the possibility of an atmospheric hazard; should the fan break down or experience a failure the possibility of an atmospheric hazard increases and is not controlled. Eliminating the possibility of a hazard is different from controlling the hazard.
Also, even if a space is not defined as a confined space, every precaution reasonable must be taken to protect workers entering the space.
4.5.4 CONFINED SPACE ENTRY PERMITS
Confined space entries must be planned and prepared for. A Confined Space Entry Permit must be completed in full for all confined space work prior to entry. The Supervisor must keep a copy at the workplace and send one copy to the Safety Coordinator.
Permits must be obtained separately for each specific job, location, person and time. Permits must not be carried from one shift to the next. A copy of the permit is to be signed off by the Authorized Entrant, Authorized Attendant and Entry Supervisor prior to entry and posted at the entrance point to the confined space.
The Confined Space Entry Permit is a valuable tool to assess the potential hazards in each confined space. It provides for a thorough review of the standard Confined Space Entry Plan, a method to ensure that all potential hazards are controlled and a further review of each party’s responsibilities while the work is being completed.
Confined Space Entry Permits are available in the Site Office, Head Office and in the Supervisor’s Job Start Up Kit. These permits must be kept on file for a period of two (2) years.
4.5.5 ATMOSPHERIC TESTING
Prior to entering a confined space, all levels of the confined space must be tested for the presence of flammable or toxic gases and vapours, oxygen deficient atmospheres, carbon monoxide and for any other hazards and the results of that testing recorded on the Confined Space Entry Permit.
If flammable or toxic gases or vapours are detected or if an oxygen deficiency is found, forced ventilation shall be used to maintain oxygen at a safe level and to prevent a hazardous concentration of flammable or toxic gases and vapours by using a fan or compressed air.
The person doing the testing must be trained. Testing must be done prior to entry, and continuously during hot work while the worker is inside the space. No entry to the confined space is to be made when:
Project Specific Safety Plan Rev. 0 March 2018 Page 55 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Explosive readings are above zero
• Oxygen readings are less than 19.5% or more than 23%
• Toxic vapours or fumes above the safe threshold limit values are present
Electric welding, gas welding, cutting or any other hot work shall not be performed on the interior, exterior or near the openings of any confined space which may contain flammable or explosive gases or vapours until the space has been properly purged. See also procedure for Gas Testing.
4.5.6 VENTILATION
The confined space must be ventilated with fresh air prior to entry. Confined spaces are to be ventilated either by natural or mechanical means but the effectiveness of natural ventilation is often unreliable. After the confined space has been cleaned, purged and ventilated, the atmosphere shall be re-tested of oxygen level, combustibility and toxicity. If the test still shows positive for any hazard, further cleaning, purging and ventilation may be required.
4.5.7 PERSONAL PROTECTIVE EQUIPMENT
Those working inside a confined space must wear appropriate personal protective equipment. This equipment varies with the work to be performed and the type of atmosphere present. The equipment may include an approved respiratory protection device, protective clothing, approved chemical goggles, hard hats, gloves and safety boots.
Where the atmosphere of a confined space cannot be guaranteed because oxygen readings are less than 19.5 % toxic gases, or vapour fumes are present, a self-contained breathing apparatus shall be worn during the complete duration of entry.
The approved self-contained breathing apparatus are:
• Self-contained Scott Air Pak – Pressure/Demand – 30-minute duration with alarm at 4 minutes of air remaining.
• Supplied air (High-pressure) – Pressure/Demand – approximately 6-hour duration with one person on 300 CF cylinder set at 750 PSI at the regulator.
Cylinders of oxygen or other gases shall not be taken into confined spaces; this does not apply to breathing equipment.
Protective clothing and respiratory equipment shall not be used as substitutes of proper cleaning and job preparation.
Employees working in sewers should launder coveralls frequently. Rubberized cotton gloves provide good hand protection. In wet places, boots and rubber overshoes protect against dampness and infection.
4.5.8 EMERGENCY AND RESCUE
Before any person enters a confined space, there must be an Authorized Attendant outside the confined space. This Authorized Attendant must be trained in both confined space and artificial respiration. A lifeline and harness assembly must always physically connect the Authorized Attendant to the person inside and
Project Specific Safety Plan Rev. 0 March 2018 Page 56 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
methods of effective communication are to be ensured and noted on the Confined Space Entry Permit.
The free end of the lifeline attached to the harness should be secured outside the enclosed space. The lifeline should be under the control of the Authorized Attendant who will keep the person inside under observation at all times.
A portable emergency alarm should be within reach of the person attending the lifeline. If the inside worker fails to answer the Authorized Attendant or seems to be behaving strangely, or if the alarm sounds on the monitor in the space, the Authorized Attendant must shout loudly to the inside worker to get out. If there is no response, the Authorized Attendant should begin pulling the person out by the harness.
If for some reason, the person in the confined space is in trouble and is not attached to a harness, or is attached to a harness but is stuck, the Authorized Attendant must not go in to rescue. Whatever overcame the person in trouble is just as likely to overcome the person going in. The Authorized Attendant must summon help by using the portable alarm or by yelling for assistance. Rescue training is absolutely necessary.
A rescue team consisting generally of at least two persons – an Observer and a Rescuer, accomplishes emergency rescues from confined spaces. The Observer is equipped with a means of summoning assistance and remains stationed near the entrance of the confined space. The Rescuer, equipped with suitable protective equipment, goes into the space to recover the casualty. The rescue team must be capable of bringing out, any worker affected and may therefore require block and tackle, safety harness, stretcher and rope. Refer to the SSERP for more information on confined space rescue.
4.5.9 HORIZONTAL ENTRIES
Horizontal confined space entries must be considered entirely different from vertical entries. In that, the physical hazard of limited access and egress is reduced and the use of standardized rescue/retrieval equipment (i.e., tripod and winch system) is not appropriate. When the opportunity for a horizontal entry presents itself; a procedure will be developed and adopted specific for that space in concert with the Corporate Health and Safety Department, Site Management personnel and Joint Health and Safety Committees.
4.5.10 TRAINING AND SUPERVISION
McNally Construction will ensure that the workforce has been trained and made aware of the following:
• Potential health hazards of working in confined spaces
• Proper procedures and precautions required for entry
• Pre-entry procedures such as lockouts, blanking of supply lines and atmospheric testing and review of the specific Confined Space Entry Plan
• Use, maintenance and limitations of protective equipment
• Proper rescue and emergency procedures
Contractors and subcontractors must ensure that McNally Construction is notified prior to confined space entry and the person in charge of the work operation must ensure that the necessary protective clothing, equipment and devices are available and that the workers are properly trained in both their use and care.
Project Specific Safety Plan Rev. 0 March 2018 Page 57 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.5.11 CONFINED SPACE OPENINGS
When covers are removed from confined spaces, a railing, temporary cover or other temporary barrier or tripod shall guard the opening. Safe access to the confined space shall be maintained at all times. If possible, all cords, hoses, leads, etc. shall be routed through an entrance other than the employee access into the confined space.
Before employees are allowed to enter a confined space, all electrical and mechanical energy sources that could affect the employees working in the space shall be physically rendered inoperative, locked out and tagged. If required, the space shall be drained, vented and cleaned.
4.5.12 RESPONSIBILITIES
Authorized Attendant
The “Authorized Attendant” is the individual designated to stay outside of the confined space to assist the individual in the confined space area. This person should also be a valid/certified First Aider. A system for signalling should be established in case of emergency.
The responsibilities of the “Authorized Attendant” include the following:
1. To maintain verbal communication with the confined space worker at all times.
2. To ensure a means of emergency signal is available, and mechanical ventilation is supplied to the confined space as required. Also, to ensure that a fire extinguisher, mechanical ventilation, emergency stretcher and SCBA are available if required for rescue.
3. Ensure that a means of retrieval is available for the confined space worker, in the event of an emergency.
4. Obtain and post at the entrance to the confined space the Confined Space Entry Permit from the Entry Supervisor, or have it available for inspection. Return permits to the Entry Supervisor at end of shift.
5. Secure free end of lifeline outside confined space in the event of an emergency to aid removal of injured confined space worker.
Authorized Entrant
1. The “Authorized Entrant” is the worker going into the confined space and has the following responsibilities:
2. Wear full body harness with lifeline when wearing a respirator to rescue a person.
3. Wear other personal protective clothing and/or equipment required.
4. If a compressed gas is required in the confined space:
• The bottles are to be mounted outside the space.
• A leak test must be conducted on the equipment, torch and hoses, prior to entering.
Project Specific Safety Plan Rev. 0 March 2018 Page 58 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
5. When work is completed, request the Authorized Attendant to close the cylinder valves, bleed hoses and torches at the gauges, if possible, and remove the equipment.
6. Ensure your equipment/tools are in good working condition prior to entry (e.g. good insulation on welding electrodes and grounding on tools and equipment).
7. Ensure a Confined Space Entry Permit is posted or available for inspection and that you have signed this permit.
Entry Supervisor
The following are the responsibilities for the Supervisor watching over the confined space entry:
1. Has the obligation to assess the potential danger involved in an operation and provide the suitable protective equipment to his area members. If guidance is required, please contact the Safety Department.
2. Ensure this procedure is complied with and provide his/her workers with the appropriate training (review of the Confined Space Entry Plan, prior to entry).
3. All workers working in the confined space shall be educated in this procedure.
4.5.13 ATTACHING CABLE CLIPS AND CLAMPING
1. Wire the thimble to the rope at the desired point, then bend the rope around the thimble and secure temporarily by wiring the rope members together.
2. First attach the clip farthest from the thimble and tighten (be sure the base of the saddle rests upon the live end of the rope and the "U" bolts on the short end.) All clips must be attached in this manner.
3. The clip nearest the thimble goes on next. Do not tighten yet. If one or more additional clips are to be attached, place them at an equal distance apart between the clips already attached.
4. Before tightening, place some stress on the rope to take up the slack and equalize the tension on both sides of the clip. (Do not apply too much stress or the clip attached in step 1 will not hold). Tighten all clips.

4.6 ELECTRICAL/MECHANICAL HAZARDS AND LOCK-OUT PROCEDURES
The purpose of this procedure is to establish the requirements for the isolation of electrical and mechanical energy sources. Isolation shall be used to ensure the health and safety of workers where the unexpected start up or release of stored, or residual, energy could cause injury
4.6.1 HAZARDS (ELECTRICAL/MECHANICAL)
• Electrical Safety Standards – All electrical installations and equipment used will meet the guidelines set out by local electrical and safety legislation.
• Temporary panel boards must be securely mounted, protected from weather and water, accessible to workers and kept clear of obstructions. All temporary panels to have labels showing voltage and breaker designations.
• Use only fuses or breakers of the recommended amperage.
• Follow approved procedures for tagging and lockout.
• Do not use extension or tool cords that are defective or have been improperly repaired.
• Do not wire plugs into outlets as disconnecting will take too long in an emergency.
• Protect cords from traffic.
• Protect bulbs with cages.
• Always use a ground fault circuit interrupter (GFCI) with any portable electric tool operated outdoors or in wet locations.
• Any shock or tingle, no matter how slight, means that the tool or equipment should be checked and repaired if necessary.
Project Specific Safety Plan Rev. 0 March 2018 Page 63 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Locate all underground and overhead services before starting work. Determine voltage of electrical utilities.
• With backhoes, cranes and similar equipment near power lines, use a signaller to warn the operator when any part of the equipment or load approaches the minimum allowable distances.
• Refer to Table 1 below for minimum safe working distances vs. voltage ratings.
Voltage Rating of Minimum Distance
Power Line
750 to 150,000 volts 3 metres (10’) 150,001 to 250,000 volts 4.5 metres (15’) Over 250,000 volts 6 metres (20’) Table 1: Minimum distance requirements for Voltage Ratings
• Before moving ladders, rolling scaffolds or elevating work platforms, always check for overhead wires. Death and injury can be caused by electrical contact with access equipment.
• Unbroken electrical contact; if you don’t know the voltage, treat it as high.
• In some electrical accidents the injured or unconscious person remains in contact with the live wire or equipment. Rescue should only be attempted after power has been turned off.
• In some cases of low voltage, when power cannot be turned off, break contact if possible. Use a dry board, rubber hose or dry polypropylene rope to move either the injured person or the wire.
• Warning: Even with dry wood or rubber, touching the injured person can be dangerous. Give first aid only after the injured person is free of contact.
• Never put water on fires in live electrical equipment or wiring. Water is a conductor and increases the risk of flash, arc and electrocution.
• An electrical fire in a confined space can rapidly deplete oxygen and may release toxic fumes. If possible, switch off power. Avoid inhaling fumes and vacate the area at once. If necessary, breathe through a damp cloth and stay close to the floor.
• Use a Class C fire extinguisher; intended for electrical fires, this type employs a non-conductive extinguishing agent. An ABC fire extinguisher may also be used on an electrical fire. Report fires immediately.
• Wiring or equipment involved in a fire must not be used until a supervisor approves it.
4.6.2 PROCEDURE
• The Supervisor involved in the electrical/mechanical work, determines where the isolation of electrical/mechanical source is required and is to notify all other supervisory personnel working in the vicinity of the systems requiring electrical or mechanical isolation to test to engage the subject equipment to confirm the isolation.
Project Specific Safety Plan Rev. 0 March 2018 Page 64 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• The Supervisor will tag and lockout the disconnect device with a scissor-type device (if required), to allow for the multiple installation of locks for other trades.
• The supervisory personnel of all trades working on the isolated electrical/mechanical system will ensure that each of their workers install locks and tags for their protection. If the same work continues into the next shift the incoming crew is to follow the same procedure after the first crew has removed their locks.
• Locks used for isolation will be individually keyed and numbered and are not be used for any other purpose. All locks and disconnects must have a “DANGER – DO NOT ENERGIZE OR OPERATE” tag securely attached.
Lockout procedures for mobile equipment including trucks are as follows:
• Mobile equipment should be parked on a firm level surface, if possible.
• All hydraulic attachments, such as blades and buckets, will either be placed on the ground, or properly braced against falling. Operator will set brakes, shut off engine and exit the cab taking the ignition key (if so equipped).
• Ignition key will be given to the Mechanic. The Mechanic will shut off the master switch.
• The Mechanic will place a lockout tag on an applicable part of the mobile equipment (i.e. the door handle or steering wheel).
• The mobile equipment will only be started either after the Mechanic has performed the work or under the direct supervision of the Mechanic.
• After the work has been finished the Mechanic will remove the lockout.
4.7 ELEVATING WORK PLATFORMS (EWP’S)
Only Competent, trained workers are permitted to use elevated work platforms. These platforms will be equipped with proper guardrails.
The platforms are to be used to raise workers and light tools only, not materials beyond its rated capacity. Workers on the platform must be protected from falling, at all times using fall arrest protection attached to designated anchor point on the platform.
The work platform must be equipped with an emergency stop button located on the work platform.
The operator’s manual must be available, at all times and no worker is permitted to use planks and/or ladders (step or otherwise) on the platform at any time. The elevating platform is to be designed, constructed, erected, maintained, inspected and monitored according to CSA standards.
When an elevating mechanism fails, a person on the work platform is to be removed prior to the platform being lowered.
Where the operator of the platform is not the person being raised on the platform there must be an effective and direct means of communication between the two.
Project Specific Safety Plan Rev. 0 March 2018 Page 65 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.8 EQUIPMENT AND VEHICLES – GENERAL PROCEDURES
Safe operating instructions are to be posted in or near the equipment where applicable and the operators manual are to be in the equipment where applicable.
Machine guards are to be installed and utilized, without exception; where they are required or in the best interest of the worker. Where a machine guard has been installed employees are not allowed to tamper with the guard or remove it. Tampering or removing the guard without permission from management may result in immediate termination of employment.
4.8.1 GETTING ON AND OFF HEAVY EQUIPMENT
1. Clean mud off boots before climbing onto the machine.
2. Use the machines side grab rails and steps.
3. Face the machine and step onto the first step.
4. Maintain three-point contact at all times. Two hands and one foot or two feet and one hand.
5. Climb into the operator's cab.
6. Before getting off the machine, make sure the machine is dogged out and further movement is prevented. Shut off machine if necessary.
7. Step out of the operator's cab, onto the ladder and while facing the machine, descend using the three- point method.
4.8.2 MAINTENANCE
Equipment will have regular maintenance completed by competent individuals. For trucks and equipment circle checks are to be completed by the operator prior to use to ensure that they are in good working condition. Any problems/concerns with the way a piece of equipment is running or operating are to be reported immediately to the shop foremen, mechanic or supervisor.
4.8.3 PREPARING EQUIPMENT FOR TRANSPORT
Whether in whole or in part, it will always be necessary for us to transport equipment using a float. During the operation of loading and unloading the equipment it is imperative to be cautious and continually aware of your surroundings.
• Ensure that all rigging hardware is appropriate for the task
• Establish a safe work area for the operation
• Implement traffic control procedures (if applicable) according to local guidelines
Project Specific Safety Plan Rev. 0 March 2018 Page 66 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.8.4 TAGGING – DEFECTIVE EQUIPMENT
When a piece of equipment is found to be defective it must be properly taken out of service. The operator will complete a “Repair Work Order” form and remove the key from the equipment. The steering wheel or main gear shift must be tagged using an “Out of Order” tag. The out of order tag must be secured using a plastic twist tie (The kind that can only be removed by cutting it off). The tag can only be removed by the mechanic after signing off on the work order that the equipment is back in proper working condition.
4.8.5 MACHINE GUARDING
Any moving part of a machine presents the hazard of personal injury; being caught in machinery is usually serious and can be fatal. Machine guarding eliminates or controls this danger.
Machinery with exposed moving parts must be guarded and the following procedures should be followed:
1. Confine long hair to prevent entanglement in rotating machine parts.
2. Do not wear loose clothing or dangling jewellery.
3. Always use the machine guards provided and know how they work.
4. Check guards regularly and report defects appropriately.
5. Be sure that all guards and safety devices are in place and properly adjusted and that all personnel are clear of the machine before turning the machine on.
6. Manual cleaning, oiling, repairing or adjusting of guards can only be done after Lock-Out Tag-Out procedures have been followed.
7. Never bypass, or make inoperative, any safety device or control on a piece of machinery. Doing so may result in immediate termination of employment.
4.9 EXCAVATION AND TRENCHING SAFETY
All excavation and trenching work must be in full compliance with jurisdictional regulations and shall be barricaded with the appropriate barrier tape and other protective devices as required.
When entering an excavation that may be considered a hazardous environment by Site Safety Representatives, proper personal protective equipment must be worn. No hazardous materials are to be stored in the trench.
Procedure
Excavations 1.2 metres or deeper or less than 1.2 metres in unstable soil shall be properly sloped (1m vertical to 1m horizontal), braced, or shored to prevent cave-ins as per jurisdictional regulations.
The trench must have a ladder for access into the excavation that extends 1m or more above the surface with no more than 7.5 metres of travel in any direction. All work described must be done in accordance with written instructions of a professional engineer if support structures are used or required as per WorkSafeBC OHS Regulation Part 20.
Project Specific Safety Plan Rev. 0 March 2018 Page 67 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
All excavated and available material shall be retained 1 metre or further from the edge of the excavation. The trench must be kept reasonably free from water.
Where a trench cage/box is to be used, McNally Construction will ensure that it is engineer certified and used as prescribed.
4.10 FALL PROTECTION AND GUARDRAILS
Fall arrest systems are required when a worker may fall:
1. More than 6 feet (1.8m);
2. More than 1.2 metres, into a work path (for a wheel barrow or similar equipment;
3. Into open machinery;
4. Into water or another liquid;
5. Into or onto a hazardous substance or object; and/or
6. Through an opening on a work surface
Where a fall from a height of less than 1.8m involves a risk of injury greater than the risk of injury from the impact on a flat surface a guardrail system shall be installed to protect a worker from these hazards. However, if it is not reasonably possible to install a guardrail system, a worker shall be protected by using a fall arrest system.
A fall arrest system must:
• Be adequately secured to an anchor point that is capable of withstanding a load of 17.8 kN
• Include a shock absorbing lanyard attached to the anchor point or lifeline, where practical above the shoulder of the user that complies with CSA standards. Lanyards must be 16 millimetres (5/8”) diameter nylon or equivalent. Lanyards shall be attached to the D-ring on the harness by locking snap hook, a spliced loop and thimble, or a D-clip attached to a spliced loop and thimble
• Prevent a free fall greater than 1.2m
• Include a full body harness that is attached to a lanyard, adjusted to the size of the user and complies with CSA standards
All lifelines must be 16 millimetres (5/8”) diameter polypropylene or equivalent and used by only one worker at a time. Lifelines must be free from any danger of chafing and free of cuts, abrasions and other defects. Lifelines must be knotted at the end, cable-clipped or otherwise provided with a positive stop, to prevent the lanyard or hitch from running off the lifeline. To attach the lanyard of a safety belt or safety harness to a lifeline, use a mechanical rope grab that meets CSA Standard Z259.2. Lifelines clipped, or otherwise provided with a positive stop to keep the hitch from running off the end of the lifeline.
If a worker falls they are not to grab the hitch lanyard or lifeline, in order to work properly the hitch must come under a load. All fall arrest equipment subjected to impacts caused by a free fall or by testing shall be removed from service.
Project Specific Safety Plan Rev. 0 March 2018 Page 68 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Prior to each use, employees shall visually inspect all fall arrest equipment for cuts, cracks, tears, abrasions, undue stretching, overall deterioration, mildew, operational defects, heat damage, acid or any other corrosion. Equipment showing any defect shall be withdrawn from service and clearly marked as damaged and removed from site. Fall arrest equipment is to be stored in a cool, dry place not subjected to direct sunlight and it is not to be used for any other purpose than Fall Arrest.
Employees must not use the fall arrest equipment until they have been properly trained. Foremen shall ensure fall protection is available and used as required for all employees under their responsibility.
Proper guardrails shall be installed on open sides of all open areas where the fall distance exceeds 2.4 metres. Guardrails will conform to Provincial Regulations. Basic wood or wire rope guardrails will have a top rail, mid- rail and toe-board secured to vertical posts or supports. All holes in the floor will be covered regardless of the depth of the hole.
A fall arrest system that has arrested a fall shall be immediately removed from service, inspected by a competent person and if not returned to original specifications it must be immediately removed from site.
4.10.1 FITTING A BODY HARNESS
A poorly fitting harness may cause unnecessary injury, even when used correctly. Follow manufacturer’s fitting instructions.
Fitting
1. Undo buckles, hold harness by front and rear D-rings to ensure straps are untwisted.
2. Pass head through straps between D-rings positioning smaller frontal D-ring on the chest and allowing straps to drape behind the body. Ask fellow worker to check length of upper straps for correct D-ring positions (see D-ring adjustment procedure).
3. Standing erect, reach to back of thighs to locate ends of sub pelvic straps. Sub pelvic strap will not be the same colour as chest strap. Pull straps from both sides so webbing is snug under the buttocks. Sub pelvic strap buckles should just reach chest strap buckles. To adjust, move orange plastic strap keepers away from quick connect buckles. Connect chest strap to sub pelvic strap by threading quick connect bar through chest strap buckle. Repeat on other side.
4. Holding buckle, feed webbing to required length adjustment. Pull excess webbing snugly through keepers. Reach between legs and locate one leg strap. Pass leg strap around front of thigh and through adjuster buckle on front of hip as before.
5. Adjust buckles to a snug fit; do not over tighten. Slide plastic keepers against quick connect buckles or feed grommeted webbing through keeper loops.
D-Ring Adjustment Procedure
Rear dorsal D-Ring should be located between the shoulder blades. Frontal D-Ring should be located below the sternum. For most fittings the D-Rings should not require adjustment.
• Holding plastic D-Ring plate with one hand pull D-Ring
• Push three bar slider against plastic D-Ring plate
Project Specific Safety Plan Rev. 0 March 2018 Page 69 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Holding D-Ring against plate, pull looped webbing on both sides through slots
• Repeat procedure if more adjustment is required
Once your harness has been adjusted according to the fitting instructions, have someone familiar with fitting procedure check adjustment of harness as outlined below. A loose or poorly fitting harness is unsafe.
Harness Adjustment Check
• Check harness adjustment by looking at and touching all harness components. Check correct location of frontal and dorsal D-Rings.
• Leg strap ends must be secured. Slide secondary plastic keepers towards end of strap and secure leg strap webbing on grommeted harness. Loose ends are dangerous. If necessary, tuck loose ends behind webbing.
• Plastic strap keepers must be placed firmly against quick connect buckles. Check webbing is flat against the body, particularly in the leg loops. Hanging in harness with twisted leg loops can compromise circulation. Check correct location of sub pelvic strap.
Do NOT alter or adapt any portion of the harness in any way. Tampering with a harness could result in unnecessary injury or death.
Maintenance and Storage
A harness must be stored, maintained and inspected properly. Failure to do so could result in harness failure.
To clean, wipe with a wet sponge. Use a mild soap if necessary. Do not use chemicals or detergents. Rinse off soap with clear water and hang to dry. Do not dry with heat.
Harnesses should be hung up by the rear Dorsal D-Ring, or placed loosely in a container. Store in a clean, dry area free from excessive hear, sunlight, harmful fumes, corrosive agents or rodents.
Harnesses can be marked for identification with marker pens only on extreme end of webbing straps.
Any repairs to your harness must be carried out by an approved servicing agent.
Following any fall incident (even a light one) the harness must be inspected by a qualified safety officer/engineer, who will decide if the harness is safe for further use or if it should be repaired or destroyed.
4.11 FIRE PROTECTION REQUIREMENTS
Be aware of the specific requirements and work area hazards that exist in your work area. Know the location, and be familiar with the use, of all safety equipment including personal protective equipment, fire extinguishers, first-aid kits and eyewash stations.
All staff should be familiar with all routes of exit from all buildings. Each jobsite will have an evacuation plan in place with a defined muster area. Each jobsite will appoint a competent person whose responsibility is to ensure that all office and shop staff are evacuated to the muster station and accounted for once a fire is discovered. As the situation dictates a designated person will contact the appropriate authorities and give them the pertinent information; location and severity of fire, information regarding injured or trapped staff,
Project Specific Safety Plan Rev. 0 March 2018 Page 70 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
etc.
Do not attempt to fight the fire unless it is minor and easily confined using a fire extinguisher. Do not return to the building until notified to do so by a member of the Fire Department.
4.11.1 USE OF FIRE EXTINGUISHERS
Good housekeeping is essential in the prevention of fires. Fires can start anywhere and at any time. It is important to know which fire extinguisher to use and how to use it.
Always keep fire extinguishers visible and easy to get at. Fire extinguishers, have to be properly maintained, to do the job. Where temperature is a factor, ensure that care is taken in selecting the right extinguisher.
Types of Fires
Class A:
• These fires consist of wood, paper, rags, rubbish and other ordinary combustible materials
• Recommended Extinguishers
• Water from a hose, pump type water can, or pressurized extinguisher, and soda acid extinguishers
• Fighting the Fire: Soak the fire completely - even the smoking embers
Class B:
• Flammable liquids, oil and grease
• Recommended Extinguishers
• ABC units, dry chemical, foam and carbon dioxide extinguishers
• Fighting the Fire: Start at the base of the fire and use a swinging motion from the left to right, always keeping the fire in front of you
Class C:
• Electrical equipment
Recommended Extinguishers
• Carbon dioxide and dry chemical (ABC units) extinguishers
• Fighting the Fire: Use short bursts on the fire. When the electrical current is shut off on a Class C fire, it can become a Class A fire if the materials around the electrical fire are ignited
4.12 FORKLIFT
When operating a forklift, you must be trained. Training must be updated every two years, at a minimum. Be aware of the specific precautions and work area hazards that exist.
Project Specific Safety Plan Rev. 0 March 2018 Page 71 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Required personal protective equipment:
• Hard hat
• Safety boots
• Safety glasses - as applicable
• Hearing protection - where noise levels exceed 85 dBbA
Check the condition of the forklift prior to use. If there is a problem have it repaired or replaced, tag the unit out of service so no one else uses it.
Prior to beginning the lift, the operator must ensure good working order of the unit. This will include an inspection of brakes, tires, cylinders, lights, fluid levels, hoses, etc.
Do not lift more weight than the equipment manufacturers’ suggested weight rating.
In the event that the Operator does not have a clear line of sight, one employee will be designated as Signal Person to assist the Operator. The Signal Person will use basic, mutually agreed upon hand signals to assist the Operator and stand in such a position so that a clear view of the Operator and the process to be performed is maintained.
There are two methods of lifting that may be employed.
1. Load positioned on the forklift forks
• Ensure that load is securely positioned. If necessary secure the load using either chain, rope or cable slings
• Tip the forks back to more securely "cradle" the load while travelling
2. Load involving lifting apparatus attached to the forklift forks
• Position forks directly over the load so that the lifting direction is straight up, as opposed to lifting in a slanted direction. In the case of pulling, or towing, the cable will be in a slated position
• Attach load utilizing the appropriate method i.e. slings into eye hooks, spreader bars, lifting rings, lift pins into dowel holes, etc
• Begin the lift and movement of the product
• Lift the load only high enough to complete the task
• Movement of the load will be done slowly
• Ensure that a clear pathway exists in the event that the load is dropped or begins to swing during the operation. This applies, firstly, to all individuals present, and, secondly, to associated property
• Upon completion of the move, the load will be lowered onto a stable surface
Project Specific Safety Plan Rev. 0 March 2018 Page 72 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Loads lowered onto a truck will be secured prior to leaving the site
4.13 FRONT END LOADERS
Never attempt to operate a loader unless you are fully qualified and authorized to do so.
Complete a circle-check around the machine.
Do not attempt to start or operate the machine from any position other than the seat provided.
To leave the loader unattended, follow the above procedures for bulldozers.
4.14 FUEL HANDLING PROCEDURES
Fuel handling must be performed with extreme care and caution; the fuels we use on site are hazardous materials and have the potential to seriously injure or cause extensive damage if they are handled negligently.
Spills, fire, explosion and inhalation of gas fumes can be mitigated, if not entirely avoided, by careful adherence to the following procedures.
It is the primary responsibility of the Supervisor to see that all fuel handling and dispensing is done in a safe and proper manner, in accordance with this procedure.
4.14.1 ENVIRONMENTAL PROTECTION PROCEDURES
The following procedures are intended to prevent a loss or escape of product and, in the event of a spill, to minimize the impact on the environment.
Delivery of Fuel to the site:
Approved tank vehicles or mobile refuelling tanks shall be used to deliver fuel. Tank vehicles are to be operated only by a competent person. Delivery can be directly into equipment or into storage tanks.
Dispensing of Fuel:
Someone must be present for all dispensing or transfer of fuel for the entire duration. The attendant is to be aware of proper fuel handling procedures. Transfer and dispensing of fuel is to be done utilizing pumping equipment, an approved hose and top-fill nozzle.
Absorbent pads are to be placed around the fuel inlet prior to dispensing as required. Ensure that a site- appropriate spill containment kit is readily available.
Unreeling of the fuel transfer hose and nozzle is to be done with the nozzle in the upright position.
The nozzle is to be kept clear of the ground when it is returned to the reel or storage position.
Verify that the fuel fill hose and the fill pipe of the tank vehicle are properly connected to the mobile refuelling tank or the equipment being filled and the fill valves are open.
Transfer of fuel is to be stopped prior to overflowing leaving room for expansion.
Project Specific Safety Plan Rev. 0 March 2018 Page 73 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Operation of moving equipment in the area of a fuelling operation is to be temporarily suspended.
Welding and/or burning operations within 3 metres will be stopped while fuelling is in progress.
Maintain regular inspections of fuel systems and their components for leakage, deterioration or damage, in accordance with applicable regulations.
4.14.2 SPILLS
Preventative measures are the best means of avoiding accidental release of petroleum products to the environment. In the event of an accidental release, the following will occur:
Appropriate spill response equipment is to be available for all phases of the project. The Spill response equipment that is available on site must include:
• On sites where storage facilities exist, a commercially available kit recommended for a 40 gallon spill.
• For sites where fuel is dispensed only (no storage facility) a commercially available kit recommended for a 10 gallon spill.
• Where the site is within 30 metres of a waterway, the kit is to include absorbent boom supplies.
Cleanup action will follow the Hazardous Materials (Spill Procedures); outlined in “Emergency Procedures” section of this policy and program.
All spills or suspected spills of petroleum products and other hazardous materials, on land or into the water, regardless of size, will be reported immediately to the Supervisor. The Supervisor will report the spill immediately to the Project Manager or Designate, who shall ensure notification of the appropriate Authorities.
4.14.3 POSTING OF PROCEDURE
Procedures for fuel handling and instructions for spills are to be posted or available on site.
4.14.4 STORAGE OF FUEL ON SITE
Where the circumstances require, fuel may be stored in an approved double walled mobile fueling tank. Storage of double walled mobile fuelling tanks when not in use is to be within an area where there is no potential for the tank to be damaged by vehicles.
The storage area is to be located away from drainage channels.
All tank vehicles and mobile refuelling tanks are to be properly labelled in accordance with the Transportation of Dangerous Goods regulations.
Approved fire extinguishers (Minimum rating of 4A, 60-B, or C) will be located near the fuel storage areas.
Smoking will not be permitted in the area of this storage facility. “No Smoking” signs are to be posted and maintained in good condition.
Smoking will not be permitted during any fuelling operation.
Project Specific Safety Plan Rev. 0 March 2018 Page 74 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
No “hot work” is to take place within 3 metres of a storage zone.
In cases where fuel is being stored on site a copy of these procedures is to be posted or available on-site and the instructions are to be relayed to employees in a “Tool Box Talk” session.
The maximum capacity of compressed gas cylinders used underground must not exceed 10 kg (22 lbs.) and containers must meet the requirements of the Transportation of Dangerous Goods Act, 1992 (Canada).
4.15 GAS TESTING
Gas detection instruments are potential life-saving devices and should be recognized as such. To ensure that this valuable piece of equipment is functioning properly a “bump test” should be completed either at the start of each day (if used continually each day) or prior to use (if only used occasionally). These instruments will be calibrated on a monthly basis to ensure that the sensors are at acceptable functional levels (calibration results to be included in the Underground Record).
McNally Construction currently uses MSA Gas Detection Monitors. These gas monitors provide real time continuous testing during use. Employees are to be properly trained on the use of each unit during project orientation.
4.15.1 USE OF GAS TESTERS
Four steps to a successful Gas Detection Program:
• Turn on instrument and check battery level
• Zero the instrument (see procedure below)
• “Bump Test” the instrument (see procedure below)
• Clear the Peaks (see procedure below)
Zeroing the Instrument
To zero the unit, do the following:
• Turn instrument on by Holding the “Mode” button until the word “RELEASE” appears on the screen
• The unit will count itself down and then stop at the “Realtime display” should have at least 3 numbers reading on the display in various corners.
• Press the “Mode” button 2 times
• The machine will say “Zero” and press “E” to start – Press the “E” button and unit will zero
• Wait and it will return to the “Realtime display”
Bump Test
The “Bump Test” or Functional Test is defined as a brief exposure of the monitor to a known concentration of gas(es) for the purpose of verifying sensor and alarm operation. It is not intended to be a measure of the
Project Specific Safety Plan Rev. 0 March 2018 Page 75 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
accuracy of the instrument.
If the instrument fails the bump test, it should have a full calibration done prior to use.
How to complete a bump test
A bump test is completed as follows:
• Turn the instrument on and warm-up.
• Apply test gas.
• Allow sensors to respond to the test gas.
• Verify proper alarm function (i.e./ lights and audible alarm)
• Remove gas and allow the monitor to clear.
Clearing the Peaks
Clearing the peaks is similar to zeroing the instrument
• Once instrument is on and at the “Realtime Display” press the “Mode” button 4 times.

Calibration
McNally Construction has purchased a docking station for calibrating instruments. Instruments must be returned to head office once per month to be docked and calibrated. If this is not feasible for a jobsite, alternate arrangements will be made to ensure the instruments are calibrated on a monthly basis.
Repairs
When a gas tester is not working properly it must be returned to Head Office. The only person allowed to do any repairs or even open the instrument is the Health and Safety Coordinator, a certified Health and Safety Technician.
4.16 GRINDING
Severe injury may occur if proper protective equipment is not used and properly maintained.
1. Check the tool rest for the correct distance from the abrasive wheel, maximum 1/8" or 3 mm.
2. Replace the grindstone when adjustment of the rest cannot provide 1/8" or 3 mm clearance.
3. If the wheel has been abused and ground to an angle or grooved, reface the wheel with the appropriate surfacing tool.
Project Specific Safety Plan Rev. 0 March 2018 Page 76 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4. Protect your eyes with goggles or a face shield at all times when grinding.
5. Each time a grinding wheel is mounted, the maximum approved speed stamped on the wheel bladder should be checked against the shaft rotation speed of the machine to ensure the safe peripheral speed is not exceeded. A grinding wheel must not be operated at peripheral speed exceeding the manufacturer's recommendation.
6. The flanges supporting the grinding wheel should be a maximum of 1/3 the diameter of the wheel, and must fit the shaft rotating speed according to the manufacturer's recommendation.
7. Bench grinders are designed for peripheral grinding. Do not grind on the side of the wheel.
8. Do not stand directly in front of grinding wheel when it is first started.
4.17 HAND AND POWER TOOLS (GENERAL PROCEDURES) 4.17.1 DEFECTIVE TOOLS

Anyone at McNally Construction, who handles, offers for transport or transports dangerous goods must be trained and certified in the applicable sections of the regulations, or else be under the direct supervision of someone who is. Dangerous occurrences shall be reported and the trained and competent person must take action to prevent further damage.
Project Specific Safety Plan Rev. 0 March 2018 Page 82 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.19.2 WHMIS
Workplace Hazardous Materials Information Systems (WHMIS) is a material labelling system that addresses the worker’s “Right to know”.
WHMIS is a national system designed to protect the health and safety of working Canadians by providing information about the hazardous materials they may come into contact with on the job.
Every McNally employee in Canada will receive WHMIS training. It will be the responsibility of the company to ensure that each worker has job specific WHMIS training.
The company shall make available hazard information on controlled products received from suppliers concerning the use, storage and handling of these products and inform workers at “Tool Box Talks”.
4.19.3 WHIMIS TRAINING
McNally will ensure that workers have received WHMIS training as soon as possible which will include:
• Education in the content, purpose and significance of information on labels and Material Safety Data Sheets (MSDS).
• Education in the use of types of identification.
• Training in the procedures for the safe storage, handling, use and disposal of controlled products.
• Training in emergency procedures involving controlled products.
The Joint Health and Safety Committee or the Health and Safety Representative may be consulted during the development, implementation and review of the job specific WHMIS training program. The company will ensure, that this WHMIS training program provides the Worker with the necessary knowledge to apply the information as needed; as is reasonably practical.
4.19.4 LOCATION OF WHMIS INFORMATION
The location of the WHMIS book containing the Material Safety Data Sheets will be in the First Aid room when there is such a room on site or close by the primary First Aid Box at each location.
4.19.5 WHMIS RESPONSIBILITIES
The Company
Responsibilities for the company will include:
• All controlled products in containers have supplier labels.
• Workplace labels are provided.
• Material Safety Data Sheet (MSDS) are readily available in the workplace.
• A current MSDS is obtained on or before the date of the first shipment of every controlled product.
Project Specific Safety Plan Rev. 0 March 2018 Page 83 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Each MSDS is current, within 3 years.
The Worker
Responsibilities for the Worker will include:
• Learn the information on controlled products which the Employer is required to provide.
• Inform the Employer when information about a controlled product is not adequate to ensure the Worker's health and safety.
*Both the Company and Workers are responsible to work together to ensure that no product that requires a Material Safety Data Sheet is permitted on the site unless the MSDS is readily available.
4.20 HEARING CONSERVATION
Hearing loss, while not fatal, can be damaging. Noise levels need to be monitored and the guidelines followed to ensure hearing protection.
Outlined below are the exposure limit guidelines without hearing protection. Controls will be implemented in the JHA for every task to reduce the exposure of excessive levels. Hearing protection required when noise levels are 85 decibels or greater.
Sound Level - in Decibels Duration – per 24h day (dBA)
90 8
92 6
95 4
97 3
100 2
102 1.5
105 1
110 0.5
Project Specific Safety Plan Rev. 0 March 2018 Page 84 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
115 0.25 or less
Over 115 No exposure
Please note; dBA and dBC noise scales are different. Low frequency noise is denoted by dBA. While dBC refers to high frequency noise, which has the potential to be more damaging because we may not be able to hear the noise and recognize the hazard.
To choose the appropriate hearing protection, in high frequency noise, subtract 7 NRR units from the capability of your chosen hearing protection. For example, if ear muffs are good for 25 NRR in low frequency (dBA) noise; those same ear muffs are effective for only 18 NRR in high frequency (dBC) noise.
Hearing protection must be chosen appropriately for the task being completed.
4.21 HOT WORK
Employees shall obtain authorizations from their Supervisor before welding, cutting or grinding; in a tunnel or confined space. Welding will only take place in atmospheres containing less than 20% of the LEL of gases or vapours. However, if explosive gases are detected at levels exceeding 10% of the LEL, a qualified person (Underground Supervisor) must first determine that welding can be performed safely, otherwise the hazard must be reduced to 10% or below of the LELs.
4.21.1 HOT WORK PERMIT
Prior to doing any Hot Work a Hot Work Permit must be completed.
4.21.2 GENERAL PROCEDURES
Work involving welding, cutting and burning can increase the fire and breathing hazard on any job, and the following should be considered prior to the start of work:
1. Always ensure that adequate ventilation is supplied.
2. Where other workers may also be exposed to the hazards created by welding, cutting and burning, they must be alerted to the hazards or protected from them by using "screens".
3. Never start work without proper authorization.
4. A fire extinguisher must always be located near any welding, cutting or burning operation.
5. Before starting, check work area for combustible material and possible flammable vapours.
6. A welder should never work alone on site.
7. Check cables and hoses to protect them from slag or sparks.
8. Never weld or cut lines, drums, tanks, etc. that have been in service without making sure that all precautions have been carried out and permits obtained.
Project Specific Safety Plan Rev. 0 March 2018 Page 85 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
9. Never enter, weld or cut in a confined space without following confined space procedures.
10. When working overhead, use fire resistant materials (blankets, tarps) to control or contain slag and sparks.
11. Cutting and welding must not be performed where sparks and cutting slag will fall on gas cylinders (move all cylinders away to one side).
12. Open all cylinder valves slowly. The wrench used for opening the cylinder valves should always be kept on the valve spindle when the cylinder is in use.
4.21.3 PORTABLE ARC WELDERS
Portable arc welders are a piece of equipment that has to be treated like a vehicle and cannot be operated indoors.
• Be sure the machine is firmly attached to the transporting unit.
• Check all fluid levels, water, oil and gas to be sure they are at acceptable levels for operation.
• When fuelling, DO NOT "top off' the gas tank. Gasoline expands as the outside temperature rises, this may result in seepage and an ensuing fire.
• Do not fuel the machine while it is running.
• Do a “walk around” to check for damage and leaks. Be sure the radiator and gas caps are in proper working order and securely attached. Any repairs should be done by qualified mechanics or technicians.
• Make sure all cables are wound securely when transporting and the side covers are kept closed to protect the machine from any damage from external objects and outside weather, as well as to protect the operator and others from the moving parts of the machine.
4.21.4 TORCHES
No welding or cutting shall be done in any area where there may be flammable materials, explosive gases or vapour without a permit to work in place.
Cutting and welding torches are made of soft metal. Never drag the torch by the hose. Keep torch tips clean of grease, oil and slag. Clogged torch tips should be cleaned with suitable cleaning wires, drills or other devices designed for the purpose.
Store equipment in a safe place, preferably in a box made for torch parts, hoses and regulators.
Always use proper fitting wrenches when making connections. Do not use vice grips or pipe wrenches.
For safety, install a reverse flow check valve to prevent dangerous flashbacks.
Do not locate cylinders where they can become part of an electrical circuit. Do not strike electrodes against a cylinder to strike an arc. All portable welding equipment must be properly grounded.
Project Specific Safety Plan Rev. 0 March 2018 Page 86 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.22 INDOOR AIR QUALITY
We are committed to providing a safe and healthy work environment for our employees. In keeping with this commitment, we recognize the importance of examining air quality when necessary.
Local exhaust ventilation will meet the appropriate standards.

All employees are expected to participate in the process whenever requested and wear the appropriate PPE as required.
4.23 LADDERS 4.23.1 PORTABLE LADDERS
Before using any ladder, make sure that it is in good condition and is the right ladder for the job to be done.
1. A single section ladder shall not exceed thirty feet in length.
2. An extension ladder shall not exceed sixty feet in length.
3. A ladder shall not be used when it has a broken or loose member or other fault.
4. A ladder shall have rungs evenly spaced at not more than twelve inches on centres.
5. A ladder shall have side rails not less than sixteen inches apart.
6. Ladders shall not be spliced together to provide long sections.
7. The minimum overlap on an extension ladder should be one (1) metre unless the manufacturer specifies the overlap.
8. Don’t overreach while on a ladder. It is easier and safer to climb down and move the ladder over a few feet to a new position. Always face the ladder when using it. Grip it firmly and use the three point contact method when moving up or down.
9. Ladders shall not be placed in front of doors opening toward the ladder unless the door is blocked open.
10. Ladders shall not be used in any horizontal position such as a platform, runway or scaffold.
4.23.2 STEP LADDERS
As with all ladders, make sure that the stepladder is in good condition, and is the right ladder for the job to be done.
• Stepladders are to be used only on clean and even surfaces and no work is to be done from the top two steps of a stepladder, counting the top platform as a rung.
• When in the open position ready for use, the incline of the front step section shall be one (1) horizontal
Project Specific Safety Plan Rev. 0 March 2018 Page 87 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
to six (6) vertical.
• The stepladder is only to be used in the fully opened position with the spreader bars locked.
• Tops of stepladders are not to be used as a support for scaffolds.
• Only CSA Standard ladders will be used.
4.24 MANUAL LIFTING
An Employee shall either obtain assistance in lifting heavy objects or use power equipment. Back belts or back braces shall be used as required.
Employees shall not attempt to lift beyond 60lbs per single lift. Caution shall be taken when lifting or pulling in an awkward position. Employees should avoid twisting or excessive bending when lifting or setting down loads. When moving a load horizontally, employees should push the load rather than pull it.
When performing a task that requires repetitive lifting, the load should be positioned to limit bending and twisting. The use of lift tables, pallets and mechanical devices should be considered.
When using such tools as screwdrivers and wrenches, employees should avoid using their wrist in a bent (flexed), extended or twisted position for long periods of time. Employees should maintain their wrists in a neutral (straight) position.
When gripping, grasping or lifting an object such as a pipe or board, the whole hand and all the fingers should be used. Gripping, grasping and lifting with just the thumb and index finger should be avoided.
When handling hazardous material proper personal protective equipment must be worn.
When two or more people are carrying a heavy object that is to be lowered or dropped, there shall be a prearranged signal for releasing the loads and if possible, everyone should face the direction in which the object is being carried.
The right way to lift is easiest and safest.
• Size up the load. If you think you need help, get it.
• Crouch or squat with the feet close to the object to be lifted,
• Secure good footing,
• Take a firm grip,
• Bend at the knees,
• Keep the back vertical and
• Lift by bending at the knees and using the leg and thigh muscles.
• Keep your balance and do not twist or turn as you lift.
Project Specific Safety Plan Rev. 0 March 2018 Page 88 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• To put the object down again, do not bend from the waist. Keep your back straight and bend your knees, keeping the object close to your body until it is placed in a secure position.
4.25 OFFICE ERGONOMICS
Repetitive Strain Injuries (RSI) have the potential to be disabling and require surgery to be resolved.
An example of an RSI would be carpal tunnel syndrome; which can develop from using computer keyboards, vibrations from power tools, repetitive gripping of hand tools, etc. The aim of ergonomics is to design equipment and work practices to reduce these kinds of injuries.
Ergonomic aspects will be considered when purchasing new equipment and designing work practices.
4.26 OVERHEAD WIRES
Extreme caution must be used when working around overhead wires.
Safety Precautions for working around Overhead Power Lines (with equipment)
• Locate and identify all overhead power lines, determine voltage before construction begins
• Where possible, have lines moved, insulated, or de-energized, contact the Local Utility company for this.
• When working near energized lines legible cautionary signs must be posted in visual range of operator. An additional sign must be posted at the operator’s station.
• Operator must be given written site specific instruction when working near overhead wires. The written instructions must be discussed with the operator and signed off on by both the operator and the supervisor giving the explanation. A copy of these instructions must be filed on site.
• For sites where there are overhead wires present a tool box talk addressing the issue will be completed with all on-site staff.
• Use a Signaller whenever a backhoe, crane or similar device is closer than one boom length to a live power line of 750 volts or more. (Signaller must be a competent worker. Signaller must receive instruction on directing operator while working close to overhead wires.)
• The Signaller must warn the operator when any part of the machine or its load approaches the minimum distance allowed in the construction regulation.
• Refer to Table 1 in section 4.6 for minimum safe working distances vs voltage ratings.
• Never use aluminum or metal-reinforced ladders near overhead lines or live electrical equipment or wiring. Even contact with a wooden ladder can be fatal under wet conditions.
• Never store material or equipment under overhead power lines if current is more than 750 volts and cranes or similar lifting devices will be involved.
• Where material or equipment must be stored under power lines, hang warning flags so that personnel will not use hoisting and lifting equipment
Project Specific Safety Plan Rev. 0 March 2018 Page 89 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Remember that overhead lines can be struck not only by booms and ladders but also by long pieces of material being lifted by hand, such as pipe.
• Be aware of wind swaying power lines into contact with equipment, hoist lines, or loads and be aware of wind blowing hoist lines or loads into contact with power lines.
• For Procedures on what to do should equipment make contact with Overhead wires see the Emergency Procedures section in this Policy and Program.
4.27 PROPANE
Since propane is heavier than air and invisible, it is a special concern when it is used on the job-site.
All installations and use of this material on the job-site must comply with the Government Legislation set out for its safe use.
Propane is non-toxic but can displace air leading to dizziness, weakness and death. There must be adequate ventilation when working with propane. Propane will flow into ditches and settle close to the ground. Propane vapour is 1.5 times heavier than air. Propane liquid is about half the weight of water. Propane will only burn at certain pressures. Combustion will not occur when there is too much or not enough fuel. When working around propane open flames and cigarettes are NOT allowed.
4.27.1 PROPANE CYLINDER STORAGE AND HANDLING
1. Storage of cylinders is to be outdoors away from entrances and confined spaces or in an approved storage area/cylinder room. Storage areas should be on firm, even ground.
2. Propane storage areas must be identified with proper signage which must include “Propane”, “No Smoking” or “No source of Ignition within 3 meters”.
3. Propane is not to be stored with oxidizing agents, oxygen and chloride cylinders. (As per MSDS)
4. Cylinders must be stored upright/vertically and secured to avoid tipping over. While in use propane bottles are to be securely held in an upright position.
5. Ensure that all valves are tightly closed when being stored or transported.
6. When moving a cylinder, move carefully, do not throw cylinders. Do not drag, roll or drop cylinders as this could cause damage.
7. When lifting cylinders follow proper lifting, carrying and mounting procedures as the cylinders are heavy when full and lifting techniques are to be used to avoid back injuries.
8. Carry only 1 cylinder at a time regardless of whether they are full or empty.
9. When transporting cylinders ensure they are properly secured and that they are transported upright/vertically. Do not transport in the cab of truck or on passenger seat. If cylinder must be transported in a vehicle ensure that it is upright, secure and the vehicle is well ventilated.
10. Never lift a cylinder by using the valve guard or the valve. A proper carrier constructed for the purpose of lifting propane and compressed gas cylinders is the only acceptable means of lifting propane tanks
Project Specific Safety Plan Rev. 0 March 2018 Page 90 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
via crane etc. Crane hooks shall be equipped with a “safety latch".
11. Tank valves and regulators are to be removed from the tank prior to any movement of the tank.
12. All trucks, cranes or equipment used to handle propane tanks must be equipped with a fire extinguisher appropriate for the size and type of tank being handled.
13. Except in an emergency, any movement or repositioning of tanks shall be performed by a competent worker.
14. Tanks are not to be heated to increase flow.
15. Tanks are not to be hooked up and used without proper regulators.
4.27.2 PROPANE HEATERS AND TORCHES
Propane must only be used in a well ventilated area and no closer than 3 meters from any source of ignition, when using propane equipment a fire extinguisher must be kept nearby.
Propane heaters are only allowed to be located in an area of a building that is under construction, where there are only construction personnel in the area. The heater must be kept away from combustible materials and set on level, solid ground.
Procedure for Connection of Heater Hose to Cylinder
• Wear gloves and eye protection
• Use regulator
• Place heater at least 15ft from the cylinder
• Face heater away from the cylinder
• Connect regulator to the cylinder
• Tighten left
• Turn the propane on slowly
• If propane flow can be heard for more than a few seconds, turn off the propane and check all connections and valves
• Test connection with soap solution
• If a leak is present turn off propane and retighten
• Turn on propane and test again
• If leak cannot be stopped by a moderate tightening effort, do not use the equipment,

4.27.3 PROPANE TRAINING
All employees handling propane for equipment operations must be fully trained in the safe handling and use of: propane bottles, hoses, regulators and the implements being powered by propane. Employees are to be instructed in the proper use, inspection and maintenance of propane equipment.
4.28 SCAFFOLDS 4.28.1 WOOD SCAFFOLDS
The construction of wood scaffold is closely regulated by legislation. The following Safe Work Practices are minimum guidelines to allay hazards and potential for injury:
1. Construction, alteration, design and removal of any wood scaffold is to be done by competent workers.
Project Specific Safety Plan Rev. 0 March 2018 Page 92 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
2. The material used to construct these scaffolds should be sound, close grained and finished on all four sides.
3. The scaffold must be capable of supporting 4 times the load that might be imposed on it.
4. All component parts should be tight together and properly fixed to each other.
5. Proper perimeter railing must be set in place: Top rail -intermediate rail -toe board.
6. Scaffold work platforms shall be at least 500 millimetres wide for light duty and 1 meter wide for heavy-duty scaffolds.
7. When used as a scaffold work platform, planks shall be secured from movement by cleats or by being wired in place.
8. Safe access and egress is to be provided to all work platforms by the use of ladders.
9. Scaffold work platforms shall not span more than 3.1 metres on light duty scaffolds or 2.3 metres on heavy-duty scaffolds.
4.28.2 METAL SCAFFOLDS
These are various types of metal scaffolds and they all have a right and wrong way to be erected.
The misuse of scaffolding is the cause of numerous serious injuries. Every worker who designs or constructs a scaffold should be competent and know what the manufacturer's specifications are for that type of scaffold.
The scaffold type that will be best suited for the job and capable of withstanding the loads to be imposed on it must be determined before the job begins.
Ensure that:
1. The scaffold you intend to use is the correct one for the job;
2. The location in which the scaffold is to be constructed is level or is capable of presenting secure footing by use of mudsills or some other device;
3. The scaffold will be erected by a competent worker;
4. Legislative and manufacturer's requirements have been complied with;
5. Safe access and egress to both the scaffold and the general work area has been provided;
6. Levelling adjustment screws have not been over extended;
7. Tower scaffolds have outriggers or are guyed and have all component parts secured in place (i.e. cross braces, pins, lateral braces);
8. Scaffold work platforms have perimeter guardrail
• Horizontal rail - 0.92 metres to 1.07 metres above the platform;
Project Specific Safety Plan Rev. 0 March 2018 Page 93 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Intermediate rail - Horizontal rail midway between scaffold platform and top rail;
• Toe board -Horizontal member at platform level no less than 140 mm in height above the platform level;
9. Scaffold planks are of number one grade materials with maximum spans of 3.1 metres on light duty and 2.3 metres on heavy duty with a maximum projection beyond the ledger of no more than 300 mm
4.29 STEEL BEAMS (MOVING NOT HOISTING)
Because of the many varied sizes, weights and site conditions, it is very important that each operation be observed for its own obvious hazards.
• Discuss the proposed work with all employees who will be involved.
• If there are any other workers in the immediate area, advise them of your work
• Determine the size, length and weight of the beams to be moved
• Check that your slings, chains and hooks are of adequate size and in good condition
• Check the beams for any obvious projections that may cause a problem
• Check the area for debris, electrical wires, buried cable, vehicles, etc.
• Designate one person to be the Signalman for the machine Operator
• The Signalman is to make sure that all others are "out of harm’s way" before signalling the machine Operator to proceed
• The machine Operator will pull the beams at a slow speed
• Always keep observers well away from the work area
4.30 TRAFFIC CONTROL
Traffic control may be required on the construction access roads at the Westridge and Burnaby Portals. Possible scenarios include, but are not limited to:
- Tunnel segment or steel pipe delivery trucks need to maneuver or backup to enter the site, fully or partially obstructing the access road
- Cement tankers may need to park on the access road while filling up the grout plant silos, fully or partially obstructing the access road
Qualified personnel must perform all traffic control. Requirements for traffic control are to conform to jurisdictional legislative requirements.
Signallers and Flagmen must be used. Signallers/Flagmen must be properly trained and receive adequate oral and written instructions. A copy of these instructions must be kept on site (see Form – “Traffic Control Training”). Signallers/Flagmen must wear an approved safety vest at all times.
Project Specific Safety Plan Rev. 0 March 2018 Page 94 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Dump trucks are to have an audible back up alarm.
4.30.1 PERSONAL PROTECTIVE EQUIPMENT REQUIRED
• Hard hat and safety boots
• Approved safety vest
• Eye protection: goggles for windy sites, safety sunglasses for sunny conditions
4.30.2 FOR TRAFFIC CONTROL AT NIGHT
• Wear a hard hat with reflective tape
• Use a flashlight with a red cone attachment as well as the STOP-SLOW sign and carry spare batteries
• Place flashing amber lights ahead of your post
• Stand in a lighted area under temporary or existing street lighting, or illuminated by lights of a parked vehicle (make sure that you stand fully in the light without creating a silhouette)
4.30.3 TRAFFIC CONTROL PERSON PLACEMENT
Stand the correct distance from the work area. Refer to the ‘Traffic Control Person’ Table below:
Posted Speed 60 km/h or less, one lane or 70 km/h or greater, one lane or reduced to one lane in each reduced to one lane in each direction direction
Traffic Volume Low High Low High
Distance of TCP from work zone 10-15 m 20-30 m 30-40 m 40-50 m
4.30.4 GENERAL GUIDELINES TO FOLLOW
• Stand the correct distance from the work area. Correct distance is pre-determined by the project supervisor using traffic control regulations/guidelines
• Do not stand on the travelled portion of a roadway and always face oncoming traffic
• Be alert at all times. Be aware of construction traffic around you and oncoming traffic on the roadway
• Stand alone. Do not allow a group to gather around you
• Stand at your post. Sitting is hazardous because your visibility is reduced and the ability of a motorist
Project Specific Safety Plan Rev. 0 March 2018 Page 95 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
to see you is reduced
• Adjust distances to suit road, weather and speed conditions
• Traffic must have room to react to your directions to stop (a vehicle can take at least twice the stopping distance on wet and icy roads)
• Stand where you can see and be seen by approaching traffic for at least 150 metres (500 feet)
• Avoid the danger of being backed over or hit by your own equipment
• Stay alert, keep your eyes on approaching traffic, and make your hand signals crisp and positive
• Coordinate your effort with nearby traffic signals to avoid unnecessary delays, tie-ups and confusion
• Do not use flags to control traffic
• Arrange with the supervisor for meal, coffee and toilet breaks
One consideration in selecting where the Traffic Control Person is positioned is to maintain a colour contrast between the Traffic Control Person and the background. The Traffic Control Person must be clearly visible to approaching motorists at all times.
Hills and curves call for three Traffic Control People or some other means of communication. The job of the Traffic Control Person in the middle is to relay signals between the other two.
Once you have been assigned a traffic control position by your Supervisor, look over the area for methods of escape - a place to get to in order to avoid being injured by a vehicle heading you way, if for some reason the driver has disregarded your signals. If this should happen, protect yourself by moving out of the path of the vehicle and then warn the crew.
4.30.5 HOW TO SIGNAL
Use the STOP-SLOW sign and your arms to direct traffic.
Hold your sign firmly in full view of the oncoming traffic.
Be sure to give the motorist plenty of warning. Do not show the STOP sign when the motorist is too close. The average stopping distance for a vehicle travelling at 50 kilometres per hour (30 miles per hour) is 45 metres (150 feet). Higher speeds will require even more stopping distance.
When showing the SLOW sign, avoid bringing the traffic to a complete halt. When motorists have slowed down, signal them to keep moving slowly.
When showing the STOP sign, use firm had signals and indicate where you want traffic to stop. When the first vehicle stops, step into the centre of the road so the second vehicle can see you.
Before moving traffic from a stopped position, make sure the opposing traffic has stopped and that the last opposing vehicle has passed your post. Then turn your sign and step back to the shoulder of the road.
Stay alert, keep your eyes on approaching traffic, and make your hand signals crisp and positive. Coordinate
Project Specific Safety Plan Rev. 0 March 2018 Page 96 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
your efforts with nearby traffic signals to avoid unnecessary delays, tie-ups and confusion. Do not use flags to control traffic.
In some situations, two-way traffic may be allowed through the work zone at reduced speed, with a traffic control person assigned to each direction. Since motorists can be confused or misled by seeing the STOP side of the sign used in the opposite lane, the signs must be modified. The STOP side must be covered to conceal its distinctive shape and command. This should prevent drivers from stopping unexpectedly.
4.30.6 COMMUNICATION
Do not be distracted by talking to fellow workers or passing pedestrians. If you must talk to motorists, stay at your post and keep the conversation brief.
When using two-way radios to communicate with another Traffic Control Person, take the following precautions:
• Establish clear voice signals for each situation and stick to them
• Be crisp and positive in your speech. If you do not understand the message as to have it repeated
• Test the units before starting your shift and carry spare batteries
• Avoid unnecessary chitchat
• Do not use two-way radios in blasting zones
When two Traffic Control Persons are working together they should always be able to see each other in order to coordinate the STOP-SLOW sign. Signals between two Traffic Control Persons should be understood (i.e. if a traffic control person changes the sign from stop to slow or vice versa he/she must inform the other Traffic Control Person by signalling with the sign in an up and down or sideways motion. This will ensure that the Traffic Control Persons coordinate their activities accordingly. Two-way radios are the best method for proper communication.
When two Traffic Control Persons are not in sight of each other; a third Traffic Control Person should be stationed who can keep both in view.
4.30.7 ENCOUNTERING PROBLEMS
Remember you have an important job to do but you are not a law enforcement officer.
• Report motorists who are endangering the safety of the public or construction workers to your Supervisor.
• Keep a pad and pencil and write down violators' licence numbers.
• Ask the Supervisor for assistance from police in difficult or unusual traffic situations.
• Never restrain a motorist forcibly or take out your anger on any vehicle.
• You should always be alert to the needs of emergency vehicles. Ambulances, Police and Fire vehicles have priority over all other traffic.
Project Specific Safety Plan Rev. 0 March 2018 Page 97 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.30.8 PREPARING FOR EACH JOB
Before starting work, make sure that you know the following:
• The type of construction you will be involved with - paving, installing pipe, grading, etc.
• The type of equipment to be used, such as scrapers, trucks, compactors, graders etc.
• How the equipment will be operating (i.e. crossing the road, moving along the shoulder, in culverts etc)
• Whether you will have to protect workers setting up components of the traffic control system such as signs, delineators, cones and barriers
• Any special conditions of the contract governing road use
• How public traffic will flow (i.e./ along a two-lane highway, around curves or hills, by detour, on a road narrowed to a single lane)
• Before starting each day ensure that the STOP-SLOW sign is clean, undamaged and meets height and size requirements
• Place the "Traffic Control Person Ahead" sign at an appropriate distance to afford motorists adequate warning
• Remove or cover all traffic control signs at quitting time or when traffic control is temporarily suspended
• Arrange with the Supervisor for meal, coffee and toilet breaks
4.30.9 BACKING UP VEHICLES/EQUIPMENT
All vehicles must have the aid of a “Back-Up Person” or “Signal Person” at all times when backing up. Drivers and operators must always obey the signaller or spotter. Workers are to stay out of the path of vehicles and equipment; to avoid entering the vehicles blind spots and reduce or prevent the hazard of being struck by equipment or vehicles.
To effectively back up vehicles:
• Designate a Signal Person for backing vehicles
• Signal Person must be trained in Traffic Control and wear appropriate PPE (traffic vest, hard hat, safety boots, etc)
• Signal Person should always stand where he can see and be seen by the driver or operator
• Signal Person should always be aware of his surroundings and people who could potentially be in the path of the vehicle
Project Specific Safety Plan Rev. 0 March 2018 Page 98 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.31 CONCRETE FORMWORK INSTALLATION
Potential Hazards
• Feet slipping on curved surface when cleaning or placing concrete blocks for invert of forms.
• Pinched fingers and feet when installing section of forms.
• Oil spraying into eyes when oiling forms.
• Workers may be struck by the traveller, when moving forms.
• Chips of steel from bolts and nuts when using air gun to tighten bolts.
Procedure
• In the initial set up of forms, invert section will be set up in bottom of shaft and braced
• Traveller will be installed next, to move invert sections into tunnel
• After all of the invert has been set and braced, sided top section will be installed
• Invert section installed in shaft will be moved to front of forms
• Top and side doors on forms will be opened; top and side bracing will be installed.
• Bulk heads will be installed at end of forms and braced
• Form vibrator and slick line will be installed as required
• After first pour, side form and invert form will be stripped.
• Invert form and one side and roof panel are moved to front of forms for placing
• Concrete blocks or spuds are used to set invert forms.
4.32 WELDING AND CUTTING 4.32.1 HOT WORK PERMIT
Prior to doing any Hot Work a Permit to Work must be completed.
4.32.2 WELDING AND CUTTING GENERAL PROCEDURES
Work involving welding, cutting and burning can increase the risk of fire and breathing hazards on any job; the following should be considered prior to the start of work.
• Always ensure that adequate ventilation is supplied
• Where other workers may also be exposed to the hazards created by welding, cutting and burning,
Project Specific Safety Plan Rev. 0 March 2018 Page 99 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
they must be alerted to the hazards or protected from them by using "screens"
• Never start work without proper authorization
• A fire extinguisher must always be located near any welding, cutting or burning operation
• Check work area for combustible material and possible flammable vapours before starting
• A welder should never work alone on site
• Check cables and hoses to protect them from slag or sparks
• Never weld or cut lines, drums, tanks, etc. that have been in service without making sure that all precautions have been carried out and permits obtained
• Never enter, weld or cut in a confined space without following confined space procedures
• When working overhead, use fire resistant materials (blankets, tarps) to control or contain slag and sparks
• Cutting and welding must not be performed where sparks and cutting slag will fall on gas cylinders (move all cylinders away to one side)
• Open all cylinder valves slowly. The wrench used for opening the cylinder valves should always be kept on the valve spindle when the cylinder is in use.
4.32.3 PORTABLE ARC WELDERS
Portable arc welders are a piece of equipment that has to be treated like a vehicle and cannot be operated indoors.
• Be sure the machine is firmly attached to the transporting unit
• Check all fluid levels, water, oil and gas to be sure they are at acceptable levels for operation
• When fuelling, DO NOT "top off' the gas tank. Gasoline expands as the outside temperature rises, this may result in seepage and an ensuing fire
• Do not fuel the machine while it is running
• Do a “walk around” to check for damage and leaks. Be sure the radiator and gas caps are in proper working order and securely attached. Any repairs should be done by qualified mechanics or technicians
• Make sure all cables are wound securely when transporting and the side covers are kept closed to protect the machine from any damage from external objects and outside weather, as well as to protect the operator and others from the moving parts of the machine
Project Specific Safety Plan Rev. 0 March 2018 Page 100 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.32.4 TORCHES
No welding or cutting shall be done in any area where there may be flammable materials, explosive gases or vapour without permit to work in place.
Cutting and welding torches are made of soft metal. Never drag the torch by the hose. Keep torch tips clear of grease, oil and slag. Clogged torch tips should be cleaned with suitable cleaning wires, drills or other devices designed for such purpose.
Store equipment in a safe place, preferably in a box made for torch parts, hoses and regulators.
Always use proper fitting wrenches when making connections. Do not use vice grips or pipe wrenches.
For safety, install a reverse flow check valve to prevent dangerous flashbacks.
Do not locate cylinders where they can become part of an electrical circuit. Do not strike electrodes against a cylinder to strike an arc. All portable welding equipment must be properly grounded
A fire extinguisher must be in close proximity when welding and cutting.
4.33 WORKING ALONE
An employee is considered to be working alone at a work site in circumstances when assistance is not readily available in the event of an injury, illness or emergency.
Ideally, no worker should be working anywhere alone for any reason. This should be avoided if at all possible. Working alone is not allowed in the tunnel or confined spaces for any reason. When a person must enter the tunnel or a confined space, then the proper procedures found in this Safety Program must be complied with.
When there is no alternative and a worker is going to be working alone on a jobsite, the Supervisor and the Employee must set up a means of communication and establish how frequently they will communicate. At a minimum the Supervisor must communicate with the Employee once per hour. On jobsites where workers from other companies are present but no other McNally Construction workers are present this is not considered to be working alone. Under these circumstances the supervisor must still check in with the employee 2 to 3 times during the day.
4.34 HEAT EXHAUSTION
Symptoms of heat exhaustion include:
• Pale, clammy skin • Rapid/weak pulse • Complaints of weakness, headaches and nausea • Sometimes cramps in abdomen or limbs.
When heat exhaustion occurs, you should:
• Move victim to a cool place, but protect from chill, • Have victim lie down with head level with or lower than the body • Give victim salt water to drink (one teaspoon of salt to one litre of water) if conscious • CALL A DOCTOR.
Project Specific Safety Plan Rev. 0 March 2018 Page 101 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.35 HYPOTHERMIA
Hypothermia is the onset of an abnormally low body temperature caused by prolonged exposure to cold conditions; it can be fatal particularly because the victim is rarely aware of what it happening until it is too late. Symptoms of hypothermia include:
• Change in appearance or behaviour • Uncontrollable shivering or unusual calmness • Stiff muscles in the neck arms and legs • Very slow shallow breathing with slurred speech • Slow irregular heartbeat, weak pulse and low blood pressure • Poor coordination and balance • Cold skin, particularly on the stomach, lower back and extremities
Hypothermia is a serious and complicated condition requiring immediate medical care. When hypothermia occurs you should:
• Prevent further body heat loss by wrapping the victim in towels, blankets, sleeping bags or clothing, endure victim’s head and neck are well covered. • Allow the victim to warm slowly by containing his body heat with wraps • Do not give hot drinks, food, alcohol or drugs.
4.36 SKIN IRRITANTS AND RASHES
Due to the diversity of materials used (solvents, acids, alkalines, resins, etc.) it is quite possible for skin irritation to occur. The following precautions could help to limit these irritations:
• Use gloves and protective clothing to avoid skin contact where possible • Wash frequently with soap and water, personal hygiene is very important • Clean equipment on a regular basis • Have a change of clothes to change into after work, prior to going home • Report all cases of skin irritations and rashes immediately to your supervisor
5 CONSTRUCTION STANDARDS - OPERATION SPECIFIC SAFE PRACTICES AND PROCEDURES
Overview
Sections 1-4 above are applicable to all areas of work, and describe the safety management approach and common safety program elements that are shared between all work segments.
This section of the safety plan serves as a project specific safe work practices and procedures for the construction activities at the for the Westridge Marine Terminal, Burnaby Terminal, and tunnel. Work at the Westridge and Burnaby portals includes secant pile installation, shotcrete application, soil installation, dewatering and general excavation. Working in the tunnel includes tunnel construction using an Earth Pressure Balance TBM and installation of a precast concrete segmental liner, installation of three steel delivery lines and backfill using cellular concrete.
Project Specific Safety Plan Rev. 0 March 2018 Page 102 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
5.1 PORTAL CONSTRUCTION (WESTRIDGE AND BURNABY TERMINALS 5.1.1 SECANT PILE INSTALLATION
Secant pile installation will be subcontracted to a specialized subcontractor. Their safe work plans, risk analysis and execution plans will be submitted and reviewed by McNally to ensure that they comply with project safety requirements.
5.1.2 EXCAVATION; SHOTCRETE AND SOIL NAILS Portal excavation, shotcrete and soil nail installation will be subcontracted to a specialized subcontractor. Their safe work plans, risk analysis and execution plans will be submitted and reviewed by McNally to ensure that they comply with project safety requirements. When excavation commences, a survey or soil test will be conducted to determine if significant levels of ionizing radiation are present at the underground working.
5.2 TUNNEL CONSTRUCTION 5.2.1 TUNNEL ENTRY / EXIT PROCEDURE
SCOPE
To ensure the safety of persons either working in or visiting the tunnel, strict procedures are to be implemented. These cover procedures for the initial entry into the tunnel, and exit procedures.
This procedure is not only intended for the regular workforce and visitors, but is to be used for all persons who may at some stage enter the tunnel. Occasional visitors will only be allowed into the tunnel when accompanied by an experienced person, however the visitor will still need to be aware of all the hazards associated with the tunnel environment. This procedure is to form part of an orientation for all first-time visitors.
PROCEDURES
• Any person, entering site must report to the site offices before proceeding onto site. Signs will be posted at the portal entrance to direct all visitors to report to the site office. Site orientation training will be provided by an experience and qualified person prior to anyone going on site. Prior to any person going below ground, specific instructions must be given detailing specific hazards relating to the tunnelling works. For persons required to work in the tunnel, full orientation training will be required, however others may require access from time to time on a visiting only basis. A visitor orientation is to be used for these persons that will identify the hazards associated with their particular visit only. An orientation checklist must be signed at the end of the orientation.
• If the visitor or worker will be going into the tunnel, they will be provided with 2 brass tags with a unique number. That number is recorded along with their name in the log book in the brass shack.
• Prior to entering the tunnel, all personnel must enter the brass shack where they will transfer their designated “Brass Tag” from the surface board “out” to the underground board “in” located at the portal entrance to the tunnel. Your second tag should be retained on your person. A log book is kept inside the brass shack with everyone’s brass tag number and the corresponding name.
• Prior to entry into the tunnel, verification that the ventilation system is working is required. In the event of prolonged absence of ventilation from the tunnel, the fans must be run for a period of 15 minutes prior to entry.
Project Specific Safety Plan Rev. 0 March 2018 Page 103 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Once ventilation has been established, checks must be carried out for dangerous gases. This will be done by reviewing the real time data from the TBM, or by means of a gas monitor inside the tunnel prior to entry.
• It is the duty of the Shift Engineer to carry out the gas monitoring below ground at the start of the shift. An underground record is filled out each day that workers go into the tunnel and includes items such as gas monitoring levels and ventilation checks. A hard copy of the underground record must be maintained in the site office at all times. Tunnel crews will carry a gas monitor into the tunnel to be kept at the working face of the tunnel at the start of each shift, thus it is not necessary for visitors to carry gas monitors.
• Entry into the tunnel will be generally by foot. Once the tunnel is excavated to a longer distance a custom built man car will be used to enter/exit the tunnel, however, visitors or workers may require entry by foot
• The deck man (at the portal entrance) and the locomotive operator have two way communication by radio. No one is permitted to enter the tunnel until they are granted clearance by the deck man, who checks with the locomotive operator to ensure it is safe to enter. If entering by foot, a radio must be carried at all times. If entering/exiting by mancar, the locomotive driver can safely drive the crew or visitors in and out.
• Walking through the tunnel involves walking along the centre of the tunnel, special curved ties are provided, which allow a clear walkway through the tunnel.
• Step ups are installed at intermediate distances throughout the tunnel (every 50-100m). A step up is an elevated platform at the side of the tunnel, that can be stood on to allow a locomotive and train to safely pass.
• When walking in the tunnel always be aware of the train’s location. Should the train start to exit while walking into the tunnel, be prepared to stop and face the train and make your way to a step up. Within the TBM trailing gantries, access is provided along the walkway on the side of the machine, access can be made beneath the gantries, however this area is not a designated walkway should only be used for trained personnel required to be in there.
• For riding on the locomotive, passenger seats have been provided on each locomotive. No more than one passenger per seat is permitted on the locomotive and all persons must be seated. No persons are to talk to the driver whilst the locomotive is in motion.
• On arrival at the face, the train will come to a stop adjacent to the rear of the machine. Do not exit until the driver has given the say so.
• Once at the place of work, ensure you are aware of the self-rescue set, fire extinguisher and first aid kit locations. Report any damage or deficiencies.
• Upon leaving the tunnel, the same procedure is followed where clearance must be given by the belt man (at the back of the TBM gantry) who will check with the locomotive operator and deck man to ensure it safe to exit.
• Once you have exited the tunnel, your brass tag must be moved from the underground “in” board to the surface “out” board. Failure to do so could result in rescue teams deployed to searching for a
Project Specific Safety Plan Rev. 0 March 2018 Page 104 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
person who has left the tunnel. Visitor tags will be removed from the brass board and returned to the site office along with self-rescue sets and to sign out.
A condensed entry procedure checklist, together with a list of site rules will be posted in the brass shack and on other notice boards. Tunnel safety systems, entry procedures and other information will be continuously updated as required.
5.2.2 EMPLOYEE IDENTIFICATION AND BRASS TAG
A Brass Board will be placed near the entrance of the tunnel. It is the responsibility of the deck man to ensure that everyone is out of the tunnel by verifying on the brass board. When no one is working in the tunnel the entrance will be deemed closed, although not physically closed (i.e. Over weekends). The deck man must check the brass board at the end of the last work shift of the week to make sure that all personnel is out of the tunnel.
Once the tunnel has passed through the Burnaby Portal, and access can be made from both ends of the tunnel, there will be a ‘Brass Board’ placed at each end of the tunnel. All personnel must check in/out at the same brass board and cannot go from one portal to the other. This will be verified by the deck man (or shift engineer if there is no deck man) who will check the brass board at the end of each shift and last work shift of the week.
5.2.3 AIR QUALITY AND VENTILATION IN TUNNEL
Fresh air shall be supplied to all underground work areas in sufficient quantities to prevent dangerous or harmful accumulation of dusts, fumes, mists vapors or gases. A summary of ventilation plan is list below:
• A full ventilation plan will be submitted to the WorkSafeBC board in full compliance with Part 22 Underground Workings Requirements.
• The ventilation system consists of a portal fan, ventilation ducts, auxiliary fan to deliver fresh air to the work face of the tunnel.
• The portal fan can be adjusted to deliver sufficient air for the de-duster if it is needed.
• A reversing fan will also be equipped on one of the gantry. This fan will only be used in case of fire to draw the smoke outside of the tunnel.
• In the event of a temporary malfunction of the ventilation system, all contaminant producing work must stop immediately, and all engines must be shut down until ventilation is restored.
• A portable air monitor must be brought in by the first crew entering the tunnel and must remain in the tunnel until the end of the shift.
• Air is continuously monitored at each individual station of the TBM and the potential gas levels are data logged as part of the TBM data logging information.
• Air quality, ventilation speed, other requirements of the Underground Record are tested for and documented on in the Underground record each shift.
• Please refer to the Ventilation Plan for more details.
Project Specific Safety Plan Rev. 0 March 2018 Page 105 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
5.2.4 LIGHTING
Lighting inside of the tunnel is set up as per WorkSafeBC Part 22 Underground Workings Requirement:
Where the use of artificial light is required, it shall be maintained while workers are entering or leaving the area.
Areas requiring the continuous use of artificial light shall be inspected regularly and defective lamps replaced.
Temporary lights shall be equipped with guards to prevent accidental contact with the bulb.
Crafts working inside the tunnel must equip with cap lamps as part of the PPE.
Approved explosion proof electrical lighting shall be the only means used for artificial illumination in areas where flammable liquids, vapors, fumes, dust or gases may be present.
Lighting will be maintained by a back-up generator in the event of a power failure. Cap lamps are mandatory underground PPE that can also be used to safely exit the tunnel in the event of a power failure / loss of lighting.
5.2.5 COMMUNICATIONS
A telephone system or an equivalent powered communication system shall be installed between the tunnel heading and portal, and first-aid station.
Powered communication systems shall be independent of the tunnel power supply and shall be installed so that failure or disruption of any one station will not disrupt the operation of any other station.
Communication systems shall be tested at the beginning of each shift and at shorter intervals when necessary to ensure reliability.
No employee will work alone unless in voice communication distance of another employee or provided with an appropriate powered communication system for obtaining instructions and emergency assistance.
5.2.6 HAZARDOUS MATERIALS
All workers must have proof of WHMIS training.
All subcontractors will supply the McNally with all up to date Material Safety Data Sheets on products that are to be used on site before delivery.
All product containers must bear the appropriate labels as per WHMIS requirements.
Any storage area for flammable products shall be reviewed by McNally and will be in accordance with the applicable legislation.
5.2.7 DANGEROUS GASES
LEL’s are combustible gases such as methane, carbon monoxide, and hydrogen. The goal is to ensure that concentrations of flammable contaminants in the tunnel atmosphere do not exceed 10% of the Lower Explosive Limit (LEL) - minimum explosive concentration, however, work can proceed up to 20% of the LELs.
Project Specific Safety Plan Rev. 0 March 2018 Page 106 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
The tunnel is evacuated if levels exceed 20% as described in the 5.2.9 gas monitoring alarms.
Ensure that oxygen content of air is not less than 19.5% and no greater than 23%. Normal ambient levels of oxygen in air is 20.9%
5.2.8 HYGIENE LEVELS
GASEOUS AGENT TWAEV STEV
Carbon Monoxide (CO) 25 ppm 100 ppm
Hydrogen Sulphide (H2S) 10 ppm 15 ppm
TWAEV - “Time-Weighted Average Exposure Value” (exposure normally over an 8-hour work day)
STEV – Short Term Exposure Value (maximum exposure over a 15-minute period)
5.2.9 GAS MONITOR ALARM SETTINGS
GASEOUS AGENT Low High
Oxygen (O2) 19.5 % 23 %
Carbon Monoxide (CO) 25 ppm 50 ppm
Hydrogen Sulphide (H2S) 10 ppm 15 ppm
LEL 10 % by volume 20 % by volume
Air quality testing is to be conducted soon as personnel goes underground with gas monitors described in section 4.15 to check if any limit stipulated above is exceeded. The monitors real time continuous testing the entire shift. Increase the frequency of checking and if necessary increase ventilation to reduce the concentration. The TBM is also equipped with air monitoring sensors in the shield (near the face of the excavation) and at the screw discharge (when the soil is first exposed to the ambient air of the tunnel). These monitors are hardwired into the software architecture that controls all the functions on the TBM.
The physical response to alarm levels would be as follows using methane (an explosive LEL gas) as an example. If concentrations exceed 10% of the lower explosive limit (LEL) ventilation will be increased to reduce the concentration with a corresponding frequency of checking. Additionally, if methane concentrations reach 10% of the Lower Explosive Limit (LEL) audible and visual alarms on the TBM are triggered. This gives the underground supervisor time to implement additional controls, such as increasing the tunnel ventilation to purge the methane or stop excavation. If methane concentrations reach 20% of the LEL, the software shuts off the power to the TBM except for the intrinsically safe electrical circuits. Also, a mechanical fault of the
Project Specific Safety Plan Rev. 0 March 2018 Page 107 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
methane detector, such as a malfunction, triggers the same response to isolate the power to the TBM.
If the concentration reaches 20%, all work will be stopped, equipment turned off and the tunnel will be evacuated immediately. The ventilation system located outside the tunnel and ducting inwards will be increased to reduce the concentration below 20% prior to anyone re-entering the tunnel.
5.2.10 COMPRESSED AIR WORK
Compressed air work or hyperbaric intervention may be required in the project. The general procedure of entering / exiting the pressurized work face. A full compresses air plan and hazard assessment will be completed in conjunction with the speciality diving contractor once it is determined to be required.
• To reach the work face, workers must pass through a man lock that is to be compressed to the working pressure.
• When leaving the compressed air workplace, workers must be decompressed to normal atmosphere by a controlled decompression, or release of air.
For each project, due to differences in the tunnelling machines, pressures and local regulatory requirements, specific project customised procedures will be required. Project specific certifications, training and decompression tables will be developed at the start of the project and will incorporate site specific conditions. At this stage, McNally will develop a detailed hyperbaric entry/exit procedure jointly with a hyperbaric company.
Health Effects (Compression)
Air Space Equalization: Lack of clear body airways for equalization causes an imbalance of pressures in body areas. For example, the Eustachian Tubes must be clear to allow the pressures on either side of the eardrum to balance, failure to do so will cause acute earache and possibly a perforated eardrum.
Health Effects (Decompression)
All decompression must be strictly controlled for the time periods indicated by the Air Decompression Tables in the CSA Standard Z275.3-M86, Occupational Safety Code for Construction Work in Compressed. If decompression is not controlled, nitrogen bubbles are formed in the tissues. Formation of nitrogen bubbles will lead to decompression sickness. There are two (2) main types of decompression sickness.
• Type I: Usually called the “bends”, this is manifested by pain in one or more of the limbs. This may commence at any time up to twelve (12) hours after decompression. The pain may be slight or agonizing.
• Type II: Affects the cardiovascular, respiratory and neurological systems. Occasionally, limb pains are present and usually appear early at the end of decompression or within forty-five (45) minutes of decompression and may show up as:
➢ Tingling, weakness, numbness or paralysis in the limbs, collapse with signs of shock
➢ Spots of flashes of light before the eye
➢ Loss of balance or consciousness
Project Specific Safety Plan Rev. 0 March 2018 Page 108 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
➢ Cardiovascular problems
➢ Abdominal pains, with or without vomiting
➢ Disorientation, memory loss, malaise if the brain is affected
LIST OF COMPONENTS OF COMPRESSED AIR WORK
• TBM Air Lock
Used to compress and decompress workers at the beginning and end of the work shift. The air lock is located in the tunnel to allow access to the TBM.
The air lock is a two compartment pressure vessel specifically designed to compress and decompress personnel entering or leaving the pressurised tunnel. The air lock consists of a primary lock and an ancillary lock. The primary lock is the chamber used for access and egress to and from the work area. When persons are working under compressed air the door between the pressurised area and the primary lock will always be open. The ancillary lock is used for persons to enter and leave the compressed air zone.
The lock is designated to be operated by competent and trained personnel, who are experienced in operating air locks and are familiar with compression and decompression procedures as required by local codes and legislation. A competent and approved person must be designated Lock Tender. It shall be the lock-tenders responsibility to effect the safe operation of the lock.
• Medical Lock
Serves two (2) purposes:
➢ Medical testing of suitability of a worker to be exposed to compressed air.
➢ Therapeutic recompressions – this lock is located on the surface within close proximity to the portal.
• Lock Tenders
Lock-Tenders for both the man lock and the medical lock will be competent people selected by the Project Superintendent to control the compression and decompression rates for the workers. Those chosen will be trained to understand the hazards associated with compression, decompression, decompression sickness and the importance of accurate record keeping. A Lock-Tender must ensure that the compression and decompression are accurate according to the established procedures.
If decanting rapid decompression to atmospheric pressure followed quickly by recompression in a separate chamber (e.g., medical lock) is conducted, the Project Physician must be notified.
In the event a worker collapses or becomes ill during decompression, the attendant must raise the pressure in the man lock to the equivalent pressure in the work chamber and immediately notify surface to alert the physician on call.
The medical lock Attendant (who may also be the air lock Attendant) will hold a current First Aid Certificate with CPR and be familiar with the aspects of working in compressed air. He will work in harmony with the Project Physician with respect to handling the medical lock.
Project Specific Safety Plan Rev. 0 March 2018 Page 109 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Treatment of Decompression Sickness
The treatment for all forms of decompression sickness is recompression. A supply of clean air at a pressure of at least 0.7 bar above the maximum working pressure used in any work chamber on the project must be available to the medical lock on site. Oxygen therapy, if used, must be given under the supervision of a physician. Because Type II-Decompression sickness may be difficult to diagnose, it is essential that all workers, who develop abnormal signs or symptoms within 24 hours of being exposed to compressed air, should be urgently recompressed.
Working Pressure and Medical Requirements
Where workers are employed at pressure up to 14 psi:
• Decompression procedures should be followed using the appropriate tables
• Exposure to pressure should be limited to two (2) periods in any 24 hour period
• Each worker must spend at least 12 consecutive hours at atmospheric pressure in any 24-hour period because the state of super-saturation still exists at the end of a normal decompression. This means that the period in compressed air plus the time required for decompression (including the time taken to reduce pressure during stages) must never exceed 12 hours
• Workers must undergo a radiographic examination of major joints unless they have been x-rayed within the previous 5 years and the x-rays results are available
• Provide health education to workers on the health hazards of working in compressed air; i.e., decompression sickness and the necessary precautions including the medical fitness criteria (to be completed by Safety Department)
Construction Projects Regulation Requirements
The Regulations for Construction Projects requires a constructor of a tunnel in which workers work in compressed air to employ at least one qualified medical practitioner preferably experienced in hyper baric medicine as Project Physician to conduct medical examinations and establish a medical treatment program for workers.
Duties of Project Physicians
• Be available to render immediate medical treatment or advice on the treatment of decompression sickness to workers working in compressed air
• Conduct medical examinations for workers before beginning work in compressed air which include a physical examination and clinical tests as required. Results of an air test in the medical lock if a worker has not previously worked in compressed air shall be reported to doctor
• Complete fitness record forms for the examined workers. Advise the Employer on the fitness of examined workers without disclosing to the Constructor and Employer the records or results of the examination or tests
• Maintain the medical records in a secure place for at least six (6) years from the last entry at which time it may be forwarded to the Chief Physician, or a Physician designated by the Chief Physician. In
Project Specific Safety Plan Rev. 0 March 2018 Page 110 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
any event, the records must not be destroyed for a period of forty (40) years from the time such records were first made or twenty (20) years from the time the last of such records were made, whichever is greater
Badge (for compressed air worker only)
• Wear badge for 24-hours after working in compressed air
• Badge shall state the name of constructor, name and telephone number of Physician, location of medical lock at project and the words “compressed air worker”
• In case of decompression sickness, take the sick worker immediately to a medical lock
Buzzer, Bell System
An electric buzzer or bell system shall consist of a switch and buzzer or bell located:
• in every work chamber near the door that leads to an air lock;
• in every air lock;
• near every lock tender’s work position
Code of Signals (post signs)
• 1 - signal – when no people are in the air lock, material is coming out;
• - signals – people are coming out of the air lock
Smoke Line
A smoke line shall be provided from each work chamber if an air lock or bulkhead is located between the chamber and the surface. The smoke line shall extend from face to ventilation system at back of gantry, for air lock on TBM.
Supervision of Decompression Procedures
The rate of decompression required by the “tables” may be doubled with respect to a worker if and while performing the work in compressed air, the worker:
• has not been exposed to air pressure greater than 220 kilopascals;
• has remained under compressed air for a maximum of 30 minutes;
• has not done manual work
Project Specific Safety Plan Rev. 0 March 2018 Page 111 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
5.2.11 CONVEYOR BELT OPERATION (WORK PROCEDURE)
Potential Hazards
Belt may overheat leading to an emission of toxic fumes from the components of the belt.
Toxic gases from the cuttings may be present as waste material is deposited onto the belt from the auger.
Pinch points exist at the drive, head, tail and tension pulleys.
Workers may be struck by material falling off the conveyor.
Worker may fall off moving conveyor or get caught on bracket holding equipment over top of conveyor.
Procedure
1. Hydrogen sulphide monitors will be placed at the discharge end of the auger to alert workers to the presence of a toxic level. To aid in the dilution of gases present, an adequate ventilation flow must be present.
2. No worker will ride the conveyor belt.
3. Before the belt is started up, an audible and visual alarm will alert the workers that the conveyor is about to operate. The control lever will have a lock out device to stop conveyor from moving when a person is on belt.
4. Fire extinguishers, 10 lbs ABC, will be readily available along the walkway of the conveyor.
5. Before any repairs, adjustments or maintenance is done, the conveyor shall be stopped and the prime mover de-energized, locked and tagged out.
6. To prevent material from falling on workers who may have to work below while the conveyor is operating guards will be in place under the conveyor at those locations.
7. To aid in the prevention of a worker becoming entangled in moving parts, any jewellery (rings, pendants, etc.) shall be removed. Workers with long hair (shoulder length or longer) whose duties require them to work in the area of the conveyor will tie their hair back or put it up in a hair net. Workers must ensure that there are no loose parts of their work clothes dangling that may become caught up in the moving parts.
8. Any work along the conveyor that requires the use of a shovel will require that the shovel does not have a hand grip, this is to allow the shovel to be pulled free from the hands in the event it becomes caught in a moving part.
9. Tripping hazards will be eliminated by maintaining a clear walkway along the conveyor.
5.2.12 CUTTERHEAD AREA – ENTRY INTO (WORK PROCEDURE)
Entrance into this area takes into consideration the requirements of confined space entry and working under compressed air (if required). Potential Hazards for this job are:
Project Specific Safety Plan Rev. 0 March 2018 Page 112 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• A worker may slip and suffer an injury
• Toxic gas or explosive gas build-up can lead to death of worker(s)
• Workers may suffer decompression sickness
• Material may fall on a worker
• Cutterhead movement while worker in the cutterhead area
• Worker may fall into semi-fluid spoil in lower part of plenum chamber
Procedure
Before any worker enters the cutter head area, air sampling will be conducted for methane, hydrogen sulphide, carbon monoxide and oxygen levels. These will be recorded.
To reduce the risk of a fall resulting in injury and assist in recovery, the worker(s) will wear fall arrest devices complete with full body harness. No less than two people will enter and/or work in the cutter head area, person will be trained in first aid, artificial respiration and CPR.
Before entering the chamber the key for energizing the TBM will be removed from the main panel, effectively locking out the machine. If rotation of the head is required during an intervention, the crew must leave the chamber before handing over the key to the operator.
Good verbal communications via telephone or another device must be present before any worker goes through the door of the air-lock leading to the cutting head.
All material, not hand held, must be securely fastened and rigged before being lowered or raised in the work area. Use of web slings and a cable puller are recommended. The movement of the machine will be under the control of the person actually in the “head” to do examination or repairs.
All workers must follow the compression and decompression procedures to reduce the possibility of decompression sickness.
Propane must be used, instead of acetylene, when using cutting torch in compressed air.
5.2.13 TUNNEL ANNULUS GROUTING (WORK PROCEDURE)
When installing either liner plate or concrete segments in tunnel, a void exists between the back of the rings and the ground. To prevent any ground settlement and to maintain the shape of the ring, it is necessary to fill this void as soon as practical after the ring has been constructed. This backfill is done by grouting through segments of the rings themselves or through the threaded coupling on the liner plate.
Potential Hazards
Liner plate will buckle if too much pressure is applied.
Grout spraying between joints of liner plate or out of hose when disconnecting grout hose from valve on liner plate or concrete segment.
Project Specific Safety Plan Rev. 0 March 2018 Page 113 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Coupling on grout hose may break causing hose and grout to spray.
Finger and arms can get caught in the mixing arms of the mixer or agitator; grout can splash into a worker's eyes when mixing grout.
Procedures
A grout mix contains cement and water; sand, fly ash/bentonite, or other additives such as accelerators, anti- wash out etc., may be used as required.
Grout may be mixed on the job site or delivered in a concrete truck. Grout may be pumped from the surface or transported to the face in a agitator car and then into a grout pump.
At the end of the last mining shift or at any time where extended stoppage is expected all hoses and tubes will be fully flushed.
For segmental grouting it will be necessary to install a valve between the injection nozzle and the grout hole. If the grout holes do not have non return valves, a valve is required to enable hose disconnection.
On completion of grouting each ring, as well as clearing hoses etc. will be cleaned of any spillage.
5.2.14 PRE-CAST SEGMENTS
ERECTION OF PRE-CAST SEGMENTS (WORK PROCEDURE)
Segments will be transported to the TBM on segment cars attached to the muck cars. There will be two (2) segment cars per train. The Segment Hoist Operator will signal the locomotive to move slowly to the heading until the segment car contacts the bumper lock. The Segment Handler must ensure the cars are locked in position and the locomotive will be stopped with brakes applied.
Potential Hazards
• Workers may be struck or run over by the cars as the cars enter the gantry
• Personnel could be entrapped between the cars and the gantry
Procedure
1. All personnel will remain out of the gantry while the trains are entering the unloading area. The Segment Hoist Operator will not signal the locomotive forward until he is assured no one is in the gantry.
2. The Locomotive Operator will give 3 blasts of his horn before entering the gantry, this is to serve as a warning. The first car, when heading to the face, will be equipped with a green flashing light to serve as a warning of the approaching train.
3. The Segment Hoist Operator, once assured the cars are in position, will activate the automatic lifters to raise the segments off the cars, allowing the train to reverse away from under the loads. After the cars have cleared the gantry area the Hoist Operator will then lift the segments with the hydraulic lift, rotate them and place them on the segment feeder. Once given the signal to back away from the segments, the train will not be allowed to travel forwards again without the express permission of the
Project Specific Safety Plan Rev. 0 March 2018 Page 114 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
superintendent or shift foreman.
Potential Hazards
• Workers can be caught between the segments and the lower catwalk in the segment moving area during rotation
• Pinch points are located between the gantry and the segments. There must be no personnel at all under the gantry areas when the train is moving forwards before dropping off the segments
Precautions
Workers must not be in the gantry area during the unloading of the segments or during rotation of the segments. A worker may be required to unhook the lifting hook from the segments after then winch operator has rotated an laid down the segment. Entry will not be allowed until the winch operator has fully lowered the segment and given the all clear.
Under the guidance of the Segment Handler, the Segment Hoist Operator will move individual segments as required to the landing pad of the erector arm.
Procedure
1. The Segment Handler and Hoist Operator must have visual communications. Proper hand signals are of prime importance.
2. Workers may get trapped if standing in front of the segment when being moved to the erector landing pad. While the segment is in motion, the handler will stand upon the safe walkway out of the travel path.
3. To prevent workers in the erector area from being struck, the Segment Handler will bring the segment to rest on the carriage in line with the bumper block (indicated by a red paint line) before any person enters.
4. The lift/lock key must be completely engaged before the segment is moved.
5. Personal protective equipment must be worn.
6. After installation of the first segment of the ring, the erector arm will be under the control of the Lead TBM Miner. The erector arm will pick-up each segment and move it into position for installation. This procedure will continue until the ring is “keyed”.
Potential Hazards
• Activity in this area will be extremely high and congested.
• “Blind” spots are evident from the erector arm control stations (there are 2 [1 upper and 1 lower]).
• A worker can be struck by falling objects (e.g., bolts, impact wrenches etc.), or a segment not installed correctly may fall on the worker(s) below.
• Installation Crew will have to reach over guardrails on platforms. This may place them in an
Project Specific Safety Plan Rev. 0 March 2018 Page 115 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
unbalanced position and increase the risk of falling.
• A worker may be struck by the erector arm when being moved back to the landing pad.
• Exposure to an eye injury is increased due to the construction of the concrete rings.
• During bolt installation and moving into position, the concrete may chip.
• Unclear communications may lead to unwarranted movement of the erector arm by one of the people at the control station.
Procedure
1. Only one Operator will begin segment movement. The other Operator will stand clear of the control panel while the erector arm is being moved.
2. The Lead Installation Person will maintain good visual and hand communications with the erector arm Controller (L or R).
3. The erector arm is not to be moved until the segment has been securely installed, the rams reapplied and the installation crew cleared from the area.
4. Impact wrenches are to be secured to prevent falling.
5. Eye protection must be worn.
6. To prevent accidental movement of the work platform, a flip type of cover will be placed over the levers once platform is in position.
UNLOADING OF SEGMENTS (WORK PROCEDURES)
When unloading segments, potential hazards exist.
Potential Hazards
When removing segments with a forklift from flat bed trucks, potential hazards to watch for are:
• Worker may become trapped between forklift and segments
• Segments may become unbalanced
• Fingers or toes may get pinched while handling segments
• When transporting the load, potential hazards may be:
• The load may become unbalanced and tip
• Worker may be struck by forklift while backing up
Project Specific Safety Plan Rev. 0 March 2018 Page 116 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Procedures
1. Prepare and engineered storage area for the segment stacks allowing for potential freeze thaw to ensure the storage stacks are stable.
2. Clearly defined hand communications must exist between Forklift Operator and Spotter.
3. The Spotter is to remove himself once the forks have been positioned. Stand to one side, clear of the load, and then signal the Forklift Operator to test the load for balance.
4. While the load is being lifted, all personnel will stand to one side of the load in
5. Once the load has cleared the flat bed, the load must be lowered to the travelling position before proceeding to the stockpile area.
6. Before starting the forklift, the Operator must complete a visual circle check and mechanical check of braking systems and hydraulics. If there are deficiencies that cannot be remedied on the spot, the machine will be shut down until examined by a mechanic. The Operator must not run the machine if it does not have the primary and back-up braking systems.
5.2.15 TRACK LAYING
Rail is brought to the TBM via flat car. The lengths are removed from the car and stored in the gantry.
Potential Hazards
• Worker could be struck by rolling stock as it enters the gantry
• Rail could slip from lifting device and strike a worker
• Pinch points could trap a worker’s hand, fingers or feet while handling the rail
Procedure
1. Personnel are to keep out of the gantry. No one will enter until the locomotive and cars have stopped and the brakes applied.
2. Once the train has entered the gantry, no one will enter until the locomotive and cars have stopped and the brakes applied.
3. While unloading the rail, car workers will ensure the load is rigged securely.
4. During transfer from flat car to storage racks, no worker will stand under the load. Stand clear to one side.
5. Workers will be alert for pinch points when handling the rail.
6. If impact hammers are used, the air hose must be “snaked” to the hammer with choker cables. Hoses and fittings are to be examined before use and secured.
7. Supervisors will periodically inspect the tools and equipment to ensure that they are in good condition,
Project Specific Safety Plan Rev. 0 March 2018 Page 117 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
any defective or improper tool is to be replaced immediately.
8. Clean up the area after job is completed, put away all tools, loose nuts and bolts in an organized manner.
9. Alert the Brakeman to inform the Locomotive Operator that a crew is leaving the gantry.
5.2.16 DERAILMENT PROCEDURES
In the event that rail cars derail during transportation, the following procedures shall be followed:
• The locomotive operator secures the train by applying the emergency brake;
• The locomotive operator will radio the portal, or in the event of radio failure go to the nearest mine phone to contact the surface and notify appropriate parties of the derailment;
• The shift supervisor along with the health and safety advisor will assess the situation and prepare a job hazard analysis for each instance of derailment.
• A crew is sent to the location of the derailment either by a second locomotive and man- car or by walking to the location;
• The work crew will use airbags and a rerailer to put the cars back on to the track using SWPs for the safe and proper use of air bags, jacks and rerailers, plus an SWP for properly securing a derailed muck car or loci will be followed;
• The work crew returns to their normal work location;
• Caution must be taken by all workers to avoid injury from overexertion when placing the railcars back on the tracks, allowing the mechanical action of the airbags to do most of the work.
5.2.17 UNDERGROUND TRANSPORT/ROLLING STOCK
Underground transport is required for a variety of reasons:
1. Worker access/egress into the tunnel
2. Delivery of segments, muck cars, rail, other mining materials into or out of the tunnel
3. General movement of the locomotive inside the TBM trailing gantries
Potential Hazards
• 4.2% uphill tunnel grade - runaways.
• Personnel can be struck or run over by moving cars.
• Brake failures or other mechanical malfunctions can lead to an uncontrollable runaway.
• Possibility of excessive build up of dangerous gases from the diesel emissions.(if diesel used )

• Pinch points occur at all couplings and on trailing gear. Hands, legs or even a whole worker may be trapped.
• Material may move and create an unstable load.
• Possibility of fire.
• Cars may derail due to excessive speed or poor track conditions.
Procedures
• Procedures have been developed to outline the precautions with respect to rolling stock in the tunnel.
• A signal light at the portal entrance will warn pedestrians that rolling stock is either in the tunnel or has exited. Signal light controlled by Surface Man or Deck Man.
• RED - DO NOT ENTER
• GREEN - ENTER WITH CAUTION
• Cautionary lights on the gantry will allow the Segment Hoist Operator to control the movement of the segment cars into the unload area. (if required)
• RED - STOP
• GREEN - PROCEED WITH CAUTION TOWARDS FACE
• AMBER – PROCEED WITH CAUTION AWAY FROM FACE
• NOTE: All lights are default to red. They only display green or amber when the control button is held by the designated flagging person.
• When operating the locomotive, the following horn signals will be used at all times and in all locations of the tunnel to indicate a change in direction:
Locomotive Signals
1 blast Stop 2 blasts Start 3 blasts Back-up Table 2: Locomotive movement indication signals
• At the beginning of each shift, the Locomotive Operator will test all braking systems, lights and audible signals. If any deficiencies are noted, the problem(s) will be rectified by the mechanical crew.
• All personnel will be instructed to recognize the locomotive signals. Workers will be instructed to keep clear of the gantry interior, except when given specific job instruction to work in the gantry.
• All workers will wear reflective marked clothing or vests when in the vicinity of the rolling stock.
Project Specific Safety Plan Rev. 0 March 2018 Page 119 Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Before being left unattended in the tunnel, the Operator of the locomotive will:
o Shut down.
o Leave controls in NEUTRAL, ensure main switch is in the non-operating position.
o Apply brakes.
• The locomotives incorporate automatic fire suppression systems. In addition a hand held fire extinguisher, minimum 10 lbs ABC will be installed on the locomotive for use in the event of a fire.
• Safety platforms will be installed at 50 to 100 metre intervals along the tunnel.
• Material will be securely fastened before being moved underground.
• Personnel are not permitted to ride between any of the cars on the train. In the event of a tunnel emergency, an empty muck car may be used to evacuate personnel. They must sit or kneel in the car.
• Nothing must be placed on top of the locomotive unless it is adequately secured, and does not extend beyond the ends or sides, nor into the cab of the locomotive, and does not obscure the operator's view.
• All personnel will be made aware of pinch point locations on the cars.
• If a worker is required to work between the cars, then the Locomotive Operator will bring the locomotive to a complete stop. Upon completion of the job, the Worker will stand well clear of the cars before signalling the driver to proceed.
• Grout and segment cars are secured in place at the face by the segment unloading locking device or other method when disconnected from the train.
• Personnel travelling on foot in the tunnel must turn to face an oncoming train.
• Inspection of the linkage system and safety cables will be conducted periodically for wear and damage.
5.3 PIPE INSTALLATION AND TUNNEL BACKFILL 5.3.1 CONCRETE (PLACING WITH CONCRETE PUMPS AND SLICK LINES)

Procedures
• Run slick line along bottom of tunnel, to tunnel form.
• Connect slick line to pumping ports on the forms.
• A phone system must be established between concrete pump, bottom of drop pipe, and forms in tunnel.
• When forms are full a rabbit is pushed through the slick line to clean out the concrete using either air or water. Extreme caution should be observed when performing this operation. A clear warning must be given to all personnel within the vicinity of the forms before commencing clean out. All personnel should be moved clear of the open end of the slick line.
5.3.2 HYDROSTATIC AND NON-DESTRUCTIVE TESTING
Hydrostatic stating and NDT testing will be subcontracted to a specialized subcontractor. Their safe work plans, risk analysis and execution plans will be submitted and reviewed by McNally to ensure that they comply with project safety requirements. At a minimum, no persons shall be allowed in the tunnel or near carrier pipes while hydrostatic testing is ongoing.
All personnel shall follow the instructions of the specialized NDT testing subcontractor. Radiographic testing can product dangerous levels of radiation. A restricted area will be delineated by the subcontractor and monitored by the subcontractor and McNally to ensure no personnel enter the area during testing.

McNally is responsible for reporting incidents to KLTP, who will report incidents to WorkSafeBC and the MOTI for any public road obstructions from an incident as per their Traffic Management Plan. 2.2 INCIDENT REPORTING
LEVELS OF EMERGENCY
McNally will participate in the three-tiered escalation approach that KLTP has adopted to respond to or support emergency situations. During the course of the emergency, the Safety Manager may increase the level status once all facts pertaining to the emergency have been assessed.
LEVEL I EMERGENCY
A Level I Emergency is an emergency where personnel, the public, or the environment are not considered at serious risk. It can be controlled by local personnel on site within a short period of time (10 minutes and/ or with minimum manpower and equipment that is immediately available at the site). A Level I Emergency can readily escalate to a higher level given certain conditions or actions. McNally will report all Level I Emergencies to the KLTP within 8 hours and submit a written report within 24 hours.
A Level I Emergency is an emergency that entails one or more of the following:
• An spill confined to either the Burnaby or Westridge Portal area or tunnel.
• Public, contractor or employee safety not endangered
• Public property not endangered
• Local response handled by District personnel
• Notification may not be required to regulatory authorities
• Little or no media interest
Examples of Level I Emergency related to tunnel activities:
➢ A smail oil spill within the tunnel – contained within the portal area.
➢ Minor inrush of ground water at the TBM head that can be controlled by sealing the head and treating water at the portal.
➢ Minor injury that can be treated with on site first aid or KLTP’s nurse.
LEVEL II EMERGENCY
A Level II Emergency is an emergency that entails one or more of the following:
• Presents a definite risk to personnel, the public or the environment.
Site Specific Emergency Response Plan Rev. 0 Page 10 March 2018

• Cannot be readily controlled by local personnel on site and requires an Emergency Response Service Provider or other external assistance to be summoned.
• May require extensive contact with the local, provincial, national and international media, as well as families and friends of employees.
• Local media interest.
• Has the potential to escalate into a Level III Emergency.
Examples of Level II Emergency related to tunnel activities:
➢ An oil spill within the tunnel that has migrated outside of portals but not in the waterway.
➢ Derailment of the rolling stock within the tunnel.
➢ Atmostpheric Hazard / Noxious Gas Detected inside of the tunnel during mining
➢ A fire within the tunnel that be put out by a fire extinguisher.
McNally will report all Level II Emergencies to KLTP within 2 hours and submit a written report within 48 hours.
LEVEL III EMERGENCY
A Level III Emergency is one that entails one or more of the following:
• Where control of the incident has been lost and which presents a serious hazard to employees, the public or the environment.
• Where the incident may seriously affect the company’s assets, reputation or image.
• Where there are one or more fatalities.
A Level III Emergency could be an emergency having progressed from a Level I or Level II emergency, depending on conditions and actions. Examples of Level III Emergency that require immediate reporting to KLTP includes:
• Any incident requiring verbal notification of a local, provincial or federal agency.
• Any NEB non-compliance incidents pertaining to TRANS MOUNTAIN.
• Any product or chemical release into a body of water or unpermitted release of gas, material, substance or chemical spill.

• Any injury requiring in-patient hospitalization or fatality
• Interrupted operations occur
• Major off-site impact has occurred
• Public, contractor, or employee safety and/or property is endangered
Examples of Level III Emergency related to tunnel activities:
➢ An oil spill within the portal that has migrated into nearby waterways
➢ A major fire within the tunnel that cannot be put out with a fire extinguisher
➢ Serious injury in the tunnel requiring hospitalization 2.3 MEDIA AND GENERAL PUBLIC ENQUIRIES
As KLTP’s sub contractor, McNally will follow KLTP’s media procedure in the case of emergency:
• McNally will not have any Press releases • Communications with family members - The project manager, together with the Human Resource Manager, will make arrangements with the RCMP to jointly notify the closest family relative in the event of critical injury or fatality to an employee working at Westridge or Burnaby Terminal. • McNally and its employees will not have any contact with media members and will direct the media to the [email protected] website for further information as it becomes released. Media contact cards will be given out, see section below. 2.4 INCIDENT REPORTING AND INVESTGATIONS
All incidents will be reported to KLTP. At a minimum all incidents will be investigated by both McNally and KLTP and corrective actions communicated for follow up. Incidents that are under the direction of KMC Operations will be investigated by TRANS MOUNTAIN or KMC with KLTP’s involvement. All incidents that effect or have effected McNally operations will be documented by McNally and KLTP regardless of who leads the investigation and reporting. 2.5 CORRECTIVE ACTION PLAN
Corrective action plans will be completed for all incidents and drill exercises. A corrective action plan is a simple document that shows the intended corrective action(s), the time frame in which it is to be completed, and who is responsible to ensure that the action gets completed. The corrective action must be specific and able to be measured for completeness.

3.3 GOALS AND OBJECTIVES / TRAINING REQUIREMENTS
KLTP has set up the Incident Command Center (ICC) which is to The ICC is to provide management support to the emergency response effort in the form of personnel, expertise, resources, information and communication. McNally will adhere to this command center and participate as required. The ICC will be activated for all Level II Emergencies or higher. All personnel will be trained in their roles and responsibilities in the event of an emergency. This shall be covered in the Site Safety Orientation. In addition, the Emergency Response Plan will be posted at a location accessible to all workers to review. All personnel must be prepared to respond as an organized team to effectively mitigate emergencies and any potential injuries.
Any personnel reporting to the KLTP ICC will attend all required training.
It is the responsibility of all personnel, either long-term or temporary, to familiarize themselves with the layout and locations of emergency response equipment and evacuation routes. Emergency equipment includes:
• Communication devices
• Alarm
• Fire extinguishers
• PPE
• First Aid Equipment
These topics will be discussed as a part of Site Orientation for employees prior to beginning work at the Westridge Marine Terminal site.
Project Management will facilitate health and safety education programs throughout the project. Depending on their task, workers will receive the following formal, documented training;
• Confined Space Training
• Fire Extinguisher Use
• Mine Rescue Training
• Tunnel Evacuation Training
• Level 3 First Aid.
• Underground Supervisor designation (General Superintendent and safety manager will be appointed as the Underground Supervisor, and will have the qualifications and responsibilities as required by WorkSafeBC Part 22 Underground Workings [22.12])
Fire extinguishers are only to be used in the tunnel or portals if you think you can put out the fire. All personnel are trained to only use extinguishers only if it is required for rescue or evacuation of the tunnel.
Site Specific Emergency Response Plan Rev. 0 Page 16 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Upon successful completion of training, workers will receive a wallet card verification certifying their competency by the McNally Safety Department.
Program Effectiveness
A review of Emergency Response Program will occur every 6 months, this will involve measuring goals and objectives, and overall effectiveness of the program. This will be done in conjunction with the biannual emergency response drills.
TESTING & DRILLS
All Personnel Shall:
• Participate in the required emergency drills and become familiar with their roles and responsibilities, as well as the location and operation of emergency equipment.
• Only personnel with specified duties shall be exempt from drills.
Drills
Emergency response drills are required to exercise and maintain the efficiency of personnel in the site-specific rescue, evacuation and lifesaving techniques. Emergency response drills be the scenario drills (where the Emergency Response Service Provider(s) will respond to a particular scenario without impacting the conduct of work) on a regular basis as determined by the Safety Manager.
Each drill type will be assessed as to its effectiveness and with areas for improvement outline and addressed. These drills will be for training purposes, as deemed necessary by the Safety Manager and will incorporate a variety of emergency scenarios.
The Safety Team may notify Project Supervision of the upcoming Emergency Response Drill. This may include the date, time, chosen scenario, and the roles they will play during the drill.
At the conclusion of the Emergency Response Drill, safety team will hold a debrief session with the Observer(s). The Safety Manager will assess each drill, including but not limited to the following:
• Evacuation efficiency
• Communications effectiveness
• Execution of roles and responsibilities
• Functionality of emergency preparedness procedures
• Drill deficiencies
Site Specific Emergency Response Plan Rev. 0 Page 17 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Corrective actions will be taken when deficiencies are noted. Drill scenarios will vary to provide personnel the opportunity to utilize all equipment, routing and options to ensure they are familiar with all established procedures and available evacuation options prior to an actual emergency.
Drills will be conducted throughout the project to ensure all parties (including the external Emergency Response Service Providers as appropriate) are familiar with their duties and the location and use of emergency equipment they are expected to use in emergency situations. Mine rescue workers will undergo proficiency drills at least every 30 days. 3.4 ON-SITE COMMUNICATIONS, PROTOCOLS, EQUIPMENT
RADIO COMMUNICATIONS
A means of communication must be present at all times at each work site or within visual distance of the worksite but not more than 500 m in distance. As well, two way radios will be available for radio communications purposes.
A regular review of the quality of radio communications will be conducted. If the quality of communications is unacceptable, McNally will review other communications options to ensure effective communications is maintained during an actual emergency. Repeaters are used to significantly extend the range of portable two way radios if communication diminishes. Base stations can be used from a fixed location in the tunnel entrance.
MINE PHONE COMMUNICATION
Communication between tunnel workers and surface crews can be made by using a mine phone. A mine phone is a hardline communication system powered independently and will be the main form of communications in the tunnel. A mine phone will be placed at the following locations:
• TBM (ie. Operators cabin, annulus grout station, back of the muck conveyor etc.)
• Supervisors trailer
• Portal entrance
• At the surface grout plant
TELEPHONE COMMUNICATIONS
Internal and external contact numbers will be available at the Westridge Marine Terminal and Burnaby Terminal Main Gate, as well as at the main office. All emergency contacts will be posted and available to all personnel.
Contacting Kinder Morgan's Control Centre (1-888-876-6711), and 911 when required, must be the first priority for the Contractor Security Lead in the event of a significant fire or serious injury. McNally will facilitate communication with KLTP’s Security Lead in the event of a significant fire or serious injury.
Site Specific Emergency Response Plan Rev. 0 Page 18 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
It is extremely important that communication with external fire or ambulance support (or other external sources as requested) ONLY be made by the KLTP Incident Command Centre.
Notifications must also be made as per the KMC / TRANS MOUNTAIN Reporting section.
ALARM COMMMUNICATION
The facility is equipped with alarms that are powered independently in case of an emergency. Should the alarm sound, stop all work, shut down any running equipment and proceed to the closest muster point to meet the Muster Supervisor for further instructions.
SIGNALING TUNNEL EVACUATIONS
The primary signal for tunnel evacuations will be voice over the mine phone.
The secondary means of communication will be:
1) Voice Communications: simple verbal commands; or
2) Flashing Lights: if lights are flashing throughout the tunnel then it is a signal from the surface to evacuate (only if contact cannot be made via mine phones)
3) Three long blasts on the air horn: to initiate an evacuation in the tunnel
3.5 EMERGENCY EQUIPMENT REQUIREMENTS
Emergency response equipment will be made available on-site. Emergency equipment includes:
• Communication devices (radios, telephone, mine phone)
• Alarms – emergency air horns to signal evacuation
• Fire extinguishers
• PPE – self rescuers, head lamps/flashlights
• First Aid Kit/Equipment
• Gas monitors
• Spill response kits
• Stretchers
• Blankets
• Self contained breathing apparatus
Site Specific Emergency Response Plan Rev. 0 Page 19 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Self contained breathing apparatus
A self contrained breathing apparatus is used during tunnel rescue when there is a potential for an atmospheric hazard in the tunnel during a rescue. The unit will provide oxygen to the wearer for a period of 60 minutes whilst walking, and up to 3 hours at rest. These units will be used for self-rescue only. These units combine a chemical removal of C02, with the addition of pure oxygen. When fully charged to 3000 psi the wearer is provided with complete protection for up to 4 hours.
All equipment will be kept within the safety trailer on site. The equipment will be checked every 30 days with a record of checks maintained by the safety manager.
All emergency equipment shall be inspected monthly and tested at a minimum annually and documented or as the manufacturers recommendations (whichever is more stringent). Testing of one time usage Emergency response equipment will not occur, that equipment will be maintained as per manufactures requirements. Only trained personnel shall use emergency response equipment or emergency PPE.
3.6 LOCATION OF ON-SITE MEDICAL EQUIPMENT AND PERSONNEL
First Aid Station
McNally will a have a dedicated first aid trailer (which also includes the mine rescue equipment) at the Westridge portal area. The Burnaby Portal area will be equipped with medical and emergency response supplies in the supervisors trailer. Any company personnel issued a McNally Construction truck must keep one small first aid box in their truck with the supplies replenished/replaced as required. Additionally, KLTP will have on site nurse which will be available to McNally.

Actions
• Change into dry clothes and avoid hot environments. Rinse skin with cool water. 4.4 RESPONSE TO FIRE
When a fire breaks out and/or an alarm sounds, ensure that:
• All employees follow evacuation procedures;
• No one will be exposed to unreasonable risk;
• All employees meet at a pre-established muster point up wind from smoke, such as a parking lot;
Site Specific Emergency Response Plan Rev. 0 Page 28 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Assessing the situation and meeting the fire department, rescue and first aid take priority over fire suppression;
Every worker should be aware of their surroundings and know the quickest exit from their workstation and an alternate exit should the exit closest to where they work be inaccessible. Every worker should also know where the fire extinguishers are around their workplace and how to use them.
FIRE EXTINGUISHERS
Only use a fire extinguisher if ALL of the following applies:
• The building is being evacuated and the fire alarm has been activated;
• The fire department (911) is being called;
• The fire is small, contained and not spreading beyond the starting point;
• The exit is clear so you can exit safely;
• You can avoid smoke inhalation;
• A proper extinguisher is properly available; and
• You know how to use a fire extinguisher.
It is important that the correct fire extinguishers be in place around the workplace. Generally most fire extinguishers at McNally are multipurpose dry chemical ABC extinguishers. Fire extinguishers are to be located near every exit and near any chemical storage and hot work operations.
• Class A fire – combustibles such as wood, textile, rubbish.
• Class B fires - grease, motor oil, and flammable liquids. Never throw water on a Class B fire as it can splatter flaming liquids over a wider area.
• Class C fires - involve electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use water to extinguish class C fires as there is a risk of electrical shock.
IF CONFRONTED BY FIRE
Think fast and act with caution
• When you first discover a fire determine what to do immediately.
• If the fire is small and you have the proper fire extinguishers, PUT IT OUT.
Site Specific Emergency Response Plan Rev. 0 Page 29 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Do not underestimate any fire – it can spread very quickly!
• If the fire is too much for you to handle, sound the alarm, report it immediately.
• Warn all the people in the area immediately so that they can get to places of safety.
• When being requested to evacuate a building or trailer:
o Stop all work
o Shut down equipment (if possible); and
o Do not return to pick up your belongings.
If you are in a room with a closed door when a fire breaks out you should:
• Check for heat or smoke around the cracks of the door and from under the door
• Do not open the door if there is smoke or the door is very warm or hot;
• Open the door carefully and slowly if it is cool and you do not see smoke;
• If you feel a burst of heat or smoke pours into the room than close the door very quickly.
• If there’s no smoke or heat when you open the door go toward your escape route exit.
Smoke Hazard
• Acrid poisonous smoke injures more people than the actual flames do.
• Stay close to the ground as smoke naturally rises. If smoke is present, drop to your knees and crawl towards your planned escape route, staying under the smoke level.
• Remember if there is a fire to leave everything behind and get out!
If your clothes catch fire
• Do not run! Instead, stop, drop to the ground, cover your face with your hands and roll. This will cut off the air and put out the flames.
Electrical Fires
• Never put water on fires in live electrical equipment or wiring. Water is a conductor and increases the risk of flash, arc and electrocution.
Site Specific Emergency Response Plan Rev. 0 Page 30 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• An electrical fire in a contained space can rapidly deplete oxygen and may release toxic fumes. If possible switch the power off, avoid inhaling fumes and vacate the area at once. If necessary, breathe through a damp cloth and stay close to the floor.
• Use a Class C or multipurpose ABC fire extinguisher
• Report fires to your Supervisor immediately.
• Call 911 immediately if the fire cannot be contained
4.5 RESPONSE TO SPILLS
Upon discovery of a hazardous materials spill, personnel will:
• REPORT the spill to a supervisor and spill clean-up personnel
• ASSESS the situation to determine the severity and potential for escalation of the danger;
• CONTAIN and CLEAN the spill with existing personnel or call for emergency assistance.
In the event of an accidental release, the following shall occur:
• EVACUATE the area for large spills
• ELIMINATE the source of the spill
• PREVENT the spill entering sewers by blocking off any drains or access to drainage
• CONTAIN the spill if it has entered or is in danger of entering a waterway
• ASSESS the method of cleanup
o In an environmentally sensitive area, get advice from the local authorities for clean-up measures
• RECOVER and CLEAN-UP spill
• CLEAN all equipment and floors
• LABEL all waste
• DISPOSE of fuel recovered and waste at an appropriate disposal facility
The supervisor on site or other designated person shall take charge of spill containment and cleanup. Workers shall be assigned to assist with control and remedial measures.
Site Specific Emergency Response Plan Rev. 0 Page 31 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Spills Reporting
All spills or suspected spills of hazardous materials or petroleum products, on land or into the water, regardless of size, will be reported immediately to the Supervisor. The Supervisor will report the spill to the QHSE Department, KLTP, and to the appropriate local authorities. 4.6 RESPONSE TO SERVERE LIGHTNING STORMS
40/30 GUIDELINE
When there is 40 seconds or less (8 miles) from "flash to bang", then you are too close to the storm and need to implement the Response to Severe Lightning Storms plan immediately. Thunder takes 5 seconds to travel one (1) mile after the flash. The average length of a lightning bolt is 8 miles and the maximum distance you can hear thunder is as short as two (2) miles and seldom exceeds twelve (12) miles.
If you are outside:
• Monitor weather and act accordingly
• Boom down all cranes and other lifting devices
• Seek shelter in a building where possible.
• Keep away from telephone and power lines, fences, trees and hilltops
• If you are on a piece of equipment, get off it as quickly as possible unless the equipment has been struck by lightning and then stay in the equipment until emergency crews can come to your aid. If you are outside and shelter is not an option:
• If your skin tingles or your hair stands on end, a lightning strike may be about to happen.
• Crouch down on the balls of your feet with your feet close together and your head down
• Keep your hands on your knees and lower your head. Get as low as possible without touching your hands or knees to the ground. DO NOT LIE DOWN!
• Keep away from telephone and power lines, fences, trees and hilltops If you are in a car:
• Stop the car and stay in it, do not stop near trees or power lines that could fall. If you are in a building:
• Stay inside and away from windows, doors, radiators, stoves, metal pipes, sinks or other electrical charge conductors
• Unplug computers, clocks, photocopiers and other electrical appliances/equipment and do not use the phone or other electrical equipment.
Site Specific Emergency Response Plan Rev. 0 Page 32 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
4.7 RESPONSE TO FLOODS
If flooding occurs, get to higher ground. Get out of areas subject to flooding. This includes dips, low spots, ravines, washes etc.
Avoid areas already flooded, especially if the water is flowing fast. Do not attempt to cross flowing streams.
Road beds may be washed out under flood waters. NEVER drive through flooded roadways.
Do not park your vehicle along streams and washes, particularly during threatening conditions.
If you are caught in fast rising waters and your car stalls, leave it and save yourself and your passengers.
Be especially cautious at night when it is harder to recognize flood dangers.
Post Flood Hazards
• Contaminated drinking water – use bottled water.
• Mould – Mould is a health hazard to some. If mould is present wear a face mask and disposable gloves, anything that stays wet long enough will grow mould, dry everything
4.8 RESPONSE TO TORNADOS
Be alert for threatening weather. Act quickly after a tornado warning. A warning means that a twister has been identified in your area.
Look for the following danger signs:
• dark, greenish sky;
• large hail;
• a large, dark, rotating cloud;
• a loud roar. If you are in the Tunnel:
• Going underground is the best location to seek shelter. If you are in a site trailer:
• Exit the trailer immediately
• Go to the lowest floor of a nearby building
• If there is no building, seek shelter on low ground such as a ditch. If you are outside:
Site Specific Emergency Response Plan Rev. 0 Page 33 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• If there is no shelter, lie flat in a ditch or ravine, protecting your head with your hands to protect yourself from flying debris. • Flying debris from tornadoes causes most fatalities and injuries.
If you are in a car:
• Get out and away from the car, it could be blown through the air or roll over on you 4.9 RESPONSE TO EARTHQUAKES
If you are in a tunnel:
• Evacuation the tunnel immediately
• Follow Part 2 of this plan for tunnel emergencies. If you are outside:
• Go to an open area and move away from buildings and any other structure that could collapse, stay away from power lines and downed electrical wires. If you are in a car:
• Stop the car and stay in it, avoid bridges, overpasses, underpasses, buildings or anything that could collapse on you and the car. Post-Earthquake hazards:
• Damaged buildings – stay out of damaged buildings even if they look alright
• After shocks – stay away from overhead hazards
• Water gets cut off – use emergency water from water heater, toilet tank or melted ice cubes
• Power can go off – stay out of elevators
• Loose or dangling electrical wires – stay away from the wires and advise authorities if you are able to do so 4.10 RESPONSE TO CONFINED SPACE
In the event that a worker needs to be rescued from a confined space, the following procedures will be taken:
• The attendant stationed outside and near the entrance to the confined space immediately summons a rescue response from the trained on-site Rescue Team. The attendant must not enter the confined space.
• The Rescue Team follows the method of rescue that is documented in the Confined Space Entry Plan (QHSE-F-57).
Site Specific Emergency Response Plan Rev. 0 Page 34 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Emergency Response Services shall be called.
• The attendant remains in constant communication with the rescue team and all workers inside the confined space until the rescue is complete.
• First Aid is administered as needed.
EMERGENCY EVACUATION OF A CONFINED SPACE Entrants must exit the confined space as quickly as possible, when:
• an order to evacuate is given by the attendant or entry supervisor
• an entrant recognizes a sign or symptom of over-exposure
• an unacceptable condition arises or
• an evacuation alarm is activated.
EMERGENCY PREPAREDNESS The Entry Supervisor will ensure the following is completed before entry into a confined space is permitted:
• The method of rescue and all the rescue equipment needed is identified in the Confined Space Entry Plan (QHSE-F-57). The plan must be available at the confined space.
• The emergency procedures are reviewed, including procedures relating to emergencies outside the confined space with all entrants and other related personnel.
The attendant must be notified immediately if an entrant recognizes:
• unusual action/ behaviour
• an unexpected hazard
• an unsafe act or
• detects a condition prohibited by the permit
4.11 RESPONSE CONTACT WITH POWER LINE BY EQUIPMENT
Stay on the equipment
• Generally it is safe for the Operator to stay on equipment in contact with a power line as long as the Operator does not touch the equipment and the ground at the same time
Keep others away
Site Specific Emergency Response Plan Rev. 0 Page 35 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• Warn everyone not to touch the equipment or its load. This includes buckets, load lines, outriggers and any other part of the machine.
• Beware of time-delayed relays. Even after line damage trips breakers, relays may still try to restore power up to two or three times – if possible, break contact by moving the equipment clear of the wires
Call Electrical Utility Company
• Call the Local Electrical Utility Company for help. Unless there is fire or imminent danger, stay on the equipment until the Utility shuts down the line and confirms that the power is off or the equipment has been moved clear of contact.
Emergency Exit
• Should an emergency such as a fire force you to leave the machine, jump clear, if part of your body contacts the ground while another part touches the machine, current will travel through you.
• Jump with feet together and shuffle away in small steps. Do not take big steps. With voltage differential across the ground, one foot may be in a higher voltage area than the other and the difference could kill you.
Report
• Report every incident of power line contact so that the utility company can check for damage that could cause the line to fall later.
4.12 RESPONSE TO PERSON IN CONTACT WITH ELECTRICITY
Electricity, even at small voltages (110V) can cause severe injury or death by causing a person's heart or lungs to stop working. In addition, electricity can also cause minor to severe burns. Serious electrical burns often times appear to be minor, due to the fact that body tissues and organs are damaged internally. The following are rescue procedures when an injured or unconscious person remains in contact with a live wire or equipment.
Emergency Response Services should be called as soon as possible.
If a person has come into contact with electricity they may not be able to remove themselves from the electrical source.
• DO NOT ATTEMPT TO PULL THE PERSON FROM THE ELECTRICAL SOURCE WITH YOUR BARE HANDS, YOU MAY BE ELECTROCUTED.
• Remember, your body is a good conductor of electricity, if you touch the person while they are connected to the electrical source, the electricity will flow through your body causing electrical shock.
Site Specific Emergency Response Plan Rev. 0 Page 36 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Rescue should only be attempted after power has been turned off.
• If you cannot locate the electrical isolating source, you can use a non-conducting object, such as a wooden pole, a dry board, rubber hose, or dry polypropylene rope to break contact. If possible, attempt to move either the injured person or the line from the electrical source. An object can sometimes be thrown to separate the injured person from the wire.
If you do not know the voltage, treat it as high.
• Never go near a victim that has been electrocuted by a high voltage line, even with dry wood or rubber. Touching the injured person can be dangerous, because the electricity can travel several feet through the air and you could be electrocuted during rescue procedures.
• Once you have removed the victim from the electrical source, check to see if the person is breathing and if they have a pulse. If necessary, administer CPR (if you are trained) until emergency personnel arrive at the scene.

5 RESPONSE TO TUNNEL EMERGENCY
The Tunnel Rescue Team is required to perform a rescue when workers become trapped in the tunnel. The Objective of the Team is to locate a trapped worker(s) and bring them out of the tunnel and to the surface. Mine rescue standards are goverened by WorkSafeBC regulations part 22 underground workings.
Rescue teams will be consistent with the number of personnel laid out in Section 3.6 and, with each member trained in the use of breathing apparatus. The project superintendent will be the Team Captain. Additionally one member will be responsible for first aid, one member for gas monitoring, one for the firefighting equipment and two for the stretcher. All crews will undertake periodic training to ensure each member is fully aware of the system. 5.1 PRE-RESCUE PLANNING
The following items should be considered when making plans to enter the tunnel:
1. What has happened underground and what information is available.
2. What assistance is available - Police, fire department, ambulance, etc. and conditions suitable for the use of such help.
3. The number of rescue personnel available
4. Route of travel
5. Visibility
6. Familiarly with location
7. The limitations of men and apparatus
8. If transportation can be used
9. Communications - are phones still working? The need to keep in contact with the rescue team 5.2 TUNNEL RESCUE PROCEDURES
In the event of an emergency below ground, the following procedures will be followed:
5) An assessment of the severity of the incident and the hazards associated with it will be made by the person in charge.
6) The necessity for the Rescue Team to respond will be decided.
7) If any doubt exists about the incident, the current Rescue Team will be mobilized.
8) When called, the Rescue Team will assemble in the safety room.
Site Specific Emergency Response Plan Rev. 0 Page 38 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
9) The first member to arrive will arrange the rescue sets, first aid kits and rescue equipment, such that every item is readily on hand.
10) On arrival of all members, the Captain will take over and will issue the orders to field test the rescue sets.
11) The sets will each be tested by the Crewmember allocated to that equipment. Each member is to don the equipment after testing is complete. The units will not be turned on at this stage but face masks will be slung around each person’s neck.
12) The stretcher; first aid kit; and, gas monitors will be checked and transported by the Crew.
13) The incident and the hazards will be reassessed before making entry into the tunnel.
14) It may be necessary to put on face mask and turn on air prior to entering the tunnel, depending upon the nature of the incident.
15) A safe area will be established outside of the tunnel at the surface. This will be referred to as the Fresh Air Base (FAB).
16) All communications to the Rescue Team will be handled from the FAB.
17) The Incident Surface Controller will direct operations from the surface.
18) The plan for the rescue will be discussed between the Rescue Team and the Incident Controller; prearranged check-ins will be arranged whereby the Team Captain is to report back to the Incident Controller.
19) The Rescue Team will turn on the breathing apparatus, don the masks and check the equipment after leaving the FAB for the tunnel.
20) The Captain will record all checks, including each member’s cylinder pressures and then again at 15 minute intervals throughout the rescue.
21) Entry will be made by locomotive and/or utility vehicle (if these modes of transport are available) as far as possible or until smoke is reached. If these modes of transport are not available or operational, the Rescue Team will enter on foot to the incident scene.
22) The utility vehicle may be taken forward through the smoke to the accident scene should conditions allow.
23) On arrival at the incident scene, the Team Captain will make an assessment. Any necessary first aid will be given, fire will be controlled as required to facilitate the rescue. The Rescue Team will carry out no fire fighting over and above what is required to facilitate the rescue.
Site Specific Emergency Response Plan Rev. 0 Page 39 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
24) All trapped persons within the tunnel will be located. Any able-bodied persons will be asked to don their self-rescuers if they have not already done so.
25) Injured persons will be treated and placed on the stretcher.
26) Should more than one person be injured, multiple trips may be required if they cannot walk out of the tunnel.
27) The most serious injured will be removed first. The entire Team will leave the tunnel keeping all other people ahead of the last man in the Rescue Team.
28) No persons wearing a self-rescuer are to assist in the rescue. They are to rescue themselves only.
5.3 TEAM BRIEFING
A briefing should take place when all information available has been assessed and decisions have been made how to locate the trapped worker(s) and get them out. The following information should be provided to the Team:
1) A summary of the situation.
2) What hazards may be expected
3) What steps must be taken to achieve their goal.
4) Forms of communication to be used.
5) Time limits.
6) Any questions from team members answered as clearly as possible.
5.4 TRANSPORT OF INJURED WORKER FROM A TUNNEL
Hard Stretchers will be kept in the Tunnel Rescue container and at the portal where work is in progress.
In the case where an injured worker is unable to walk out of the tunnel, the stretcher will be carried by the Rescue Team. The stretcher can also be secured to the flat car and transported out by the locomotive, slowly and carefully so not to aggravate the injured person. If a locomotive is not available, the car can be pushed out manually by workers.
If two or more injured workers are unable to walk out of the tunnel, a second stretcher will be brought into the tunnel. Then, any injured worker will be carried or transported out of the tunnel as above.
Site Specific Emergency Response Plan Rev. 0 Page 40 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
If more than two workers are unable to walk out of the tunnel, the most seriously injured workers will be brought out first. Afterwards, the locomotive will return for the other workers.
On completion of the rescue, with all members back at the FAB, breathing sets will be removed and the team will return to the rescue container. A report is to be completed by the Team Captain while the information is still fresh in the mind.
No further entry into the tunnel is to be made prior to a full assessment by the Project Supervisor, Incident Controller and Team Captain.
5.5 FIRST AID RESPONSE TO UNDERGROUND WORKER(S)
An assessment of the situation will be made by the person in charge. At the very least, the severity of the injury(s) and the appropriate rescue equipment and procedure will be assessed.
For an injury below ground the following steps will be taken:
A trained and competent First Aider will take charge of the situation.
Hazards at the scene are assessed and the area is made safe
A quick assessment is made of possible life threatening conditions.
An assessment of the severity of the injury and the need for outside assistance is made
Assistance is called upon from fellow workers, as required
A First Aider identifies himself and offer assistance to the Injured Worker.
• First Aid and CRP is administered as appropriate.
• Direct a person to notify the Site Office and/or Deck Man using the tunnel telephone. • If Emergency Response Services are required at the scene, a person is to be sent to the site gate to direct the Ambulance to the tunnel. Ensure free access to the tunnel entrance is maintained.
• No attempt should be made to move an injured person who has is suspected to have sustained a neck or spinal injury traumatic injury unless in danger of further injury.
• The incident is to the be reported to the Supervisor as soon as possible
The following information must be provided to the Deckman for an injured underground worker requiring evacuation:
Your Name
Name of injured person
Site Specific Emergency Response Plan Rev. 0 Page 41 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
Location of incident
What the injuries are to the best of your knowledge
If 911 Emergency Response Services are required
Any special equipment required, such as stretcher, backboard, splints, additional first aid equipment etc., to be brought into the tunnel, Automated External Defibrillator (AED).
5.6 TUNNEL EVACUATIONS
The tunnel will be evacuated under the following circumstances:
• Uncontrollable fire within the tunnel
• Heavy smoke
• Atmospheric explosion • Sustained failure of power to the ventilation system
• Complete failure of ground support
• Uncontrollable flooding
• Atmospheric Hazard (low oxygen, high LEL, high H2S, high CO) Although a temporary malfunction of the ventilation system is not grounds for immediate evacuation, all contaminant producing work must stop immediately, and all engines must be shut down until ventilation is restored. Oxygen testing must remain ongoing during temporary malfunction and it is up to the discretion of the underground supervisor if evacuation is required.
Evacuation Procedures
In an emergency evacuation, persons are to take themselves from the tunnel. No attempt at rescue is to be made. Rescues are for the trained and prepared personnel.
• All Supervisory personnel will be responsible for head counts and will restrict access into the evacuation area except to emergency crews.
• If required, the Tunnel Rescue Team will be notified along with outside authorities.
• The Project Manager and Supervisor will notify personnel at the termination of the evacuation and permit the safe return to normal procedures.
• Everyone will take a self-rescuer with them, leaving every tool/pump/appliance as is.
Site Specific Emergency Response Plan Rev. 0 Page 42 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• A message will be made on the mine phones of the evacuation
• The crew will evacuate to the nearest tunnel end.
• A head count of all personnel will be completed by the foreman for each crew, accounting for all project personnel onsite will.
• The head count will be verified by a supervisor prior to release of personnel for return to work or any other release
• After the foreman and supervisor have both walked to the heading and agree to clear the tunnel, tunnel production may resume.
Signaling a Tunnel Evacuations
The primary signal for tunnel evacuations will be voice over the mine phone.
The secondary means of communication will be:
4) Voice Communications: simple verbal commands; or
5) Flashing Lights: if lights are flashing throughout the tunnel then it is a signal from the surface to evacuate (only if contact cannot be made via mine phones)
6) Three long blasts on the air horn: to initiate an evacuation in the tunnel
Escaping From the Tunnel with a Self-Rescuer
• Begin your escape calmly; do not rush.
• Proceed to the nearest tunnel entrance where there is access to the surface
• Behave calmly. Hurrying makes you breathe more quickly and uses up more oxygen.
• Make sure that the half mask is tight (position of half mask).
• The air from self-rescuer will be warm and dry.
• Take care not to damage or squash the breathing bag and so waste life-saving oxygen.
• If you have to vomit, take the mouthpiece out of your mouth but keep it sealed with the thumb. Do not vomit into the oxygen self-rescuer.
• Do not start to breathe in again until you have put the mouthpiece back into your mouth so that you do not inhale toxic substances from the ambient air.
Site Specific Emergency Response Plan Rev. 0 Page 43 March 2018
Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
• The Drager Oxy K-Plus self-rescuer will provide oxygen to the wearer for a period of 60 minutes whilst walking, and up to 3 hours at rest. These units will be used for self- rescue only.
5.7 FIRE IN A TUNNEL
Limited attempts may be made at fighting incipient fires with fire extinguishers provided. The following guidelines are adhered to:
• Every underground personnel has been notified of a fire and is on the escape side of any fire
• If smoke is heavy, don a self-rescuer
• Surface notification has been made
• Unnecessary personnel are evacuated from the area
• Ventilation has been reversed (if heading fire)
• Electrical circuits have been shut down on TBM except for ventilation.
• Size of the fire has been evaluated to be within control.
• The TBM is equipped with a refuge chamber and fire suppression system in the event that a fire in the tunnel breaks out and workers cannot safely pass it to get out.
5.8 EXPLOSIONS IN A TUNNEL
The most explosive gas that can be encountered in a tunnel is Methane. Methane is lighter than air and if ignited within its explosive range will “fireball” across the crown of the tunnel.
If an explosion is encountered in the tunnel:
• Don a self-rescuer and drop flat onto the invert of the tunnel;
• Once the fire has passed overhead, keep low and stay where you are unless the situation dictates that you have to move.
• The fire will consume much of the oxygen in the area so it is important to keep the self- rescuer on once the explosion and fire has past.
• The TBM is equipped with a refuge chamber and fire suppression system in the event that there is an explosion in the tunnel and workers cannot safely pass the area to get out.

Trans Mountain Expansion Project: Burnaby Mountain Tunnel McNally Construction Inc.
6 WORKING ON KMC FACILITIES
If Kinder Morgan Canada pipeline or facilities have been impacted in any way, KMC EM Liaison must be notified. McNally is responsible for all emergency response within the tunnel and portal areas. Emergency response for anthing outside of the tunnel portals at KMC terminal facilities is the responsibility of KLTP. The KLTP Incident Commander will contact McNally’s Safety Manager for all major emergencies on the terminals that may affect McNally including but not limited to major fires and spills or releases from existing infrastructure or natural hazard emergencies requiring a muster or evacuation of the site.
