Permit to Work Procedure S3[APAC]-218-PR1

APAC

1. Purpose and Scope a. Permit to Work is an effective control strategy when engaging in certain prescribed high risk work (non-routine) to ensure that the work has been adequately planned and risk assessed, with appropriate controls identified and approved by a competent person in order to ensure safe work practices are observed. b. This procedure outlines the general requirements for the Permit to Work system, including the authority to issue work permits, the situations where a permit is required, the assessment process to be considered prior to the issue of a permit, the conduct of work in accordance with the permit and closure of the permit. c. Given AECOM are engaged in a variety of roles and varying levels of responsibility for site works, the AECOM PM is to assess whether project activities are under the management and control of AECOM in applying the requirements of this permit to work system on a project.

2. Procedure

2.1 Requirement for a Permit to Work

Prescribed high risk work requiring a Permit to Work include: a. Excavation: excavation works under management and control of AECOM, where mechanical excavation work is >150mm deep and wide (including drill bore diameter), require an Excavation Permit - APAC, or equivalent) in line with the Permit to Work Procedure – APAC.

Note: exemptions are allowed in line with Excavation and Trenching Procedure – APAC. Service identification and clearance (SIC) activities relating to excavation mist be performed in accordance with Service Identification and Clearance Procedure – ANZ. b. Blasting / Explosives: Permit to Work (Non-Specified Task) – APAC is required prior to any preparation for blasting work within the project area. The contractor will supply a marked up drawing of the blast, a drilling program and blast pattern diagram detailing all the requirements of the blast. c. Demolition: Permit to Work (Non-Specified Task) - APAC is required for all work methods when bringing down buildings or structures. a. Hot Work: Hot Work Permit – APAC is required for all Hot Work except for that work carried out exclusively within a designated hot works area (e.g. permanent workshop), unless these areas remain designated as hazardous zones e.g. for Oil and Gas clients. b. Isolations: Permit to Work (Non-Specified Task) – APAC is required when working on or near any plant or equipment that has, or may have, hazardous material or a stored energy source as identified in Lockout and Tagout (LOTO) Safety Procedure. c. Confined Space: Confined Space Entry Permit – APAC is required for all Confined Space work as identified by the Confined Space Procedure – APAC or relevant legislation. d. Lifting Operations: Lifting Operation Permit – APAC is required for all non-incidental lifts involving cranes and other powered lifting appliances. A particular subset under this category is: i. Suspended personnel basket (manage/workbox) - allowing personnel access to heights/depths. e. Working at Height: A Work at Height Permit - APAC is required for all AECOM work using fall injury minimisation systems (Level 4) to verify suitable controls are in place. This permit may also be used in other circumstances where the task risk assessment determines a work at height permit to be a necessary control.

Other non-routine high risk work tasks (e.g. asbestos removal, tree felling, etc.) may be identified through the risk assessment process as requiring a Permit to Work as a control measure. In these circumstances a bespoke Permit to Work (Non-Specified Task) – APAC shall be developed (in absence of any other suitable alternative available) for the task with appropriate controls defined. The general principles outlined throughout the rest of this procedure shall be adopted for all works under Permit to Work system. 2.2 Training Requirements a. All persons involved in Permit to Work activities shall be trained and competent in the task(s) outlined in the permit scope and risk assessment. Competency may be achieved through a combination of training, education, experience, acquired knowledge and skills. b. The Regional SH&E Director is to make an assessment of local available permit to work training as to what is most applicable within their area of responsibility. As a guideline, where a nationally recognised unit standard of training exists around permit to work, this should be the benchmark noting that application of this training may vary dependent on AECOM scope of work, role on project and/or associated risk. c. In addition to permit system training, those responsible for issuing and receiving permits shall hold any necessary core training for the particular type of work being permitted (e.g. confined space training to issue a confined space permit, or geotechnical engineering qualifications to issue an excavation permit). d. Contractors must be able to show evidence of current competency for the task they are undertaking or where they are adopting a supervisory role or as the Permit Issuer. 2.3 Permit Development & Preparation a. The permit and associated supporting documents essentially form a contract between the Permit Issuer and the Permit Receiver. Therefore, adequate detail is needed to specify the work to be carried out, its location, the hazards associated with the work and the environment, and the required controls. The scope of work needs to be clear enough so that any other person can understand exactly what the work involved is, including any equipment or resources to be used. b. Supporting documentation accompanying the permit application should be readily traceable and referenced to avoid any ambiguity. Such information may include but is not limited to risk assessments, drawings, site plans, sketches, services plan, Safety Data Sheets, emergency response plans, equipment operation manuals, standard operating procedures, standards, regulations, codes of practice, registers, and checklists. c. Where non-AECOM permits are proposed to be used on an AECOM-controlled project, an assessment (gap analysis) shall be undertaken to verify that the third-party permit system meets the minimum requirements of the AECOM standard. Where gaps are identified, the higher standard of the two systems shall be adopted and application confirmed as part of the project risk register and/or SH&E Management Plan. Where this is unclear the Project Manager /Director should be consulted as well as the local SH&E Manager. 2.3.1 Multiple Jobs a. Multiple jobs are allowed at the discretion of the PM and Permit Issuer, provided an adequate risk assessment has been completed, risks addressed and required controls implemented e.g. additional component persons to manage multiple jobs. b. A given Permit may cover one job or a group of jobs in the same geographic area that requires the same precautions and isolation procedures, however, separate Permits will be required for jobs with different precautions or isolations. c. At the discretion of the Permit Issuer, a single recipient may sign as the Receiver for each Permit to Work or multiple Permits to Work as the supervisor of various work groups, only if he/she can supervise each group adequately. This condition and the number of people working on the job must be recorded in the relevant section of the Permit to Work form. Each person working on the job must place their Personal Danger Tag/Lock on individual isolations to ensure their safety is not compromised.

2.3.2 Isolation a. The Permit Issuer shall ensure that all the necessary isolations are in place, have been tagged with an OUT OF SERVICE/DO NOT OPERATE tag and locked where appropriate. All electrical isolations must be checked for effectiveness by the competent person (licensed electrical worker). b. Isolations must be documented using an Isolation Sheet or marked Piping & Instrumentation Diagrams, (P&ID), and be attached to the Permit to Work or suitably referenced. 2.3.3 Permit to Work Register a. The Permit Issuer shall ensure that all permits are registered in the appropriate work permits register established for the project. In situations where very few permits are generated on a project a register may not be required. 2.4 Issue of Permit to Work (Authorisation) a. The Permit Issuer shall initiate a Permit to Work by: i. Involvement with the development of a task risk assessment (e.g. SWMS) to ensure that the job can be done safely, that necessary isolations are in place, and that all appropriate controls measures have been identified and allowed for, ii. Entering details of the permit onto the Permit Register (as applicable), and then iii. Completing all relevant sections of the appropriate Permit to Work Form up to and including authorisation for the work to proceed. b. The Receiver shall: i. Read the Permit to Work ii. Discuss hazards and precautions with the Permit Issuer, and iii. Where deemed necessary by either party, review the job at the job site c. The Permit Issuer shall then issue the Permit to Work: i. The Receiver shall sign the acceptance of the Permit to Work, clearly noting the period of validity (time and date) ii. All permit requirements shall be communicated to permit users, and iii. The original Permit to Work shall remain “open” in the field typically for the duration of the work e.g. 12 hours and not longer than 24 hours and be clearly displayed.

Note: The issue of a permit does not by itself make a job safe. 2.5 Withdrawal of Permit to Work (Suspension) a. Should any of the following situations arise, the Permit Receiver must stop work and notify the Permit Issuer of this and vice versa: i. There is a change in conditions at the site which introduces new hazards to a task being done e.g. severe weather, other contractors working nearby, etc. ii. When work has ceased for the shift, if the job is incomplete iii. During any emergency alarm/situation, including trial evacuations iv. If the scope of the permit or risk assessment changes, rendering stated precautions inadequate v. A change in shift or change of Permit Issuer of Receiver vi. At the discretion of the Permit Issuer or Receiver. b. If the scope of the job executed under the Permit to Work should change after it has been signed, the Permit to Work shall be reissued to reflect the change in scope of work, or a new Permit to Work issued.

c. The Permit Issuer and operations personnel in direct operating control of plant and equipment shall have the authority to stop the work and withdraw the Permit to Work at any time. d. Every person on site has the right to discuss withdrawal of a Permit to Work at any time with the Permit Issuer. 2.6 Permit Revalidation a. Prior to recommencing work e.g. after lunch-break, the permit must be revalidated. The Permit Register (if applicable) will be updated each time a permit is revalidated. b. To revalidate, the Issuer and Receiver are required to: i. Check the integrity of all isolations; ensure that conditions have not changed since the permit was suspended. ii. Check that no new hazards have been introduced iii. Inspect the worksite to ensure the site is safe for the work to proceed iv. Ensure stakeholders are aware of revalidation. 2.7 Duration of Permit to Work a. The normal period of validity for a Permit to Work is the duration of a shift (i.e., 12 hours). The maximum period shall nominally be 24 hours but however for standard activities it might be rolled over for the work week however the permit issuer must re-check the site conditions to confirm there has been no change in the initially assessed risk and conditions based on which the permit was issued. b. A Permit Issuer may extend the Permit to Work if the job is incomplete when the Permit expires, provided there are no additional hazards, and the precautions specified on the original Permit to Work still apply. c. Any extension granted must be signed by a Permit Issuer and re-accepted by the Receiver. The maximum period of extension shall be defined on the permit. After this time a new Permit to Work shall be created. 2.8 Job Completion (Permit Closure) a. At job completion, the Receiver shall: i. Remove all Personal Danger tags/locks; and ii. Sign, time and date the original Permit to Work form and return to the Permit Issuer for closure. b. The Permit Issuer shall: i. Ensure the equipment has been returned to service, or is ready for return to service ii. Ensure the Receiver has left the site in an appropriate level of housekeeping iii. Sign, time and date Job Completion part the original permit iv. File the completed signed off original permit in accordance with project document management requirements, and v. Ensure the safe return to normal workplace operations. 2.9 Permit to Work Records a. Records shall be maintained in a readily accessible manner, to include: i. Records of training of Permit to Work Receivers and Issuers ii. Permit to Work registers iii. Copies of permits and supporting documentation in accordance with project document management requirements. Retention shall be retained for a minimum of 12 months after job completion.
