Mondarra 9 Drilling and Mondarra 1 Plug & Abandonment Program Environmental Plan Document Summary

1 INTRODUCTION

1.1 Background and purpose The Mondarra Storage Facility (MSF) is located within production licence L1. The MSF comprises of a previously extracted gas reservoir being utilised as a gas storage facility. The facility currently has 17.5PJ of usable gas storage capacity and the capability to inject gas at 70TJ/day and withdraw gas at 150TJ/day. The MSF is located within the Shire of Irwin, approximately 350km north of Perth (Figure 2.1). The storage facility is expected to be operational for a period of at least 70 years. Gas from the MSF is transported to the market for use via the existing Parmelia (PL1) and/or Dampier to Bunbury (PL40) natural gas transmission pipelines. APA has recently completed a significant capacity enhancement of the MSF following increased commercial demand for gas storage in the south west of Western Australia (WA). Associated works involved the drilling of two additional wells (Mondarra 6 and 8) and the construction of a new surface facility to allow for gas compression, transfers and processing at the currently permitted 70TJ/day injection and 150TJ/day extraction. In order to meet the required injection and extraction rates a new well is required to replace the old suspended well M1 that was drilled in 1968. Planning for a mew injection and production well is now underway. This will be the Mondarra 9 well (M9). The old suspended M1 well will be plugged and abandoned (P&A). The old M1 well is located approximately 50 metres from M9. These activities are the subject of the M9 Drilling and M1 P&A Environment Plan. A drilling service agreement has been reached between APA and Enerdrill Pty Ltd (ED) to conduct the operations utilising Enerdrill Rig 3 (to drill M9) and Enerdrill Rig 1 (to P&A M1). On-ground site preparation activities for the drilling program are scheduled to commence in October 2015, with drilling operations commencing in late 2015. The M1 P&A operations will follow-immediately after M9 is drilled. The proposed drill site is totally located within the area leased from the freehold landowner for the existing MSF operations. A significant portion of the land to be prepared for the drilling operations is within the currently cleared and compacted pad for the M1 well and associated MSF equipment. The remainder will require the clearing, backfilling and compaction of previously disturbed agricultural land which has been largely cleared of native vegetation for pastoral land use and cropping. Part of the pastoral land to be cleared includes an area less than 1Ha of remnant native vegetation. There are no sensitive environmental receptors in close proximity to, or likely to be affected by the drilling program.

1.2 Scope The M9 Drilling and M1 P&A Environment Plan has been prepared to cover APA’s environment management for the following operations: . Accessing the M9 site and establishing infrastructure to support drilling activities (drill pad, sumps, flare pit, laydown and storage areas). . Mobilising Enerdrill Rig 3 to site, rigging up, drilling and completing an injection and production well (M9) into the Dongara sandstone storage formation. . Demobilising Enerdrill Rig 3 and cleaning-up the site. . Bringing in Enerdrill Rig 1 for the M1 P&A work. M1 is located alongside M9 on the same leased area. . Plugging and abandoning the M1 well, in accordance with a Well Management Plan approved by the DMP.

MSF-PL-LH-6002_0 Page 1

Mondarra 9 Drilling and Mondarra 1 Plug & Abandonment Program Environmental Plan Document Summary

. Demobilising and leaving the site ready for future tie-in of M9 to the MSF facility. . Monitoring and rehabilitating sumps and pits associated with the project will take place over a period of time. Rehabilitation to a compacted surface around the well will occur as the sumps dry out and become susceptible to backfilling and compaction. . The drill pad area will not be rehabilitated with top soil and vegetative matter but will remain part of the MSF operational areas. Once the well has been completed, a separate environment plan bridging document will, if necessary, be prepared and lodged with the DMP to cover M9 final completion, testing and flowline tie-in operations to the MSF.

1.3 Objectives The M9 Drilling and M1 P&A EP has been prepared in accordance with the Petroleum and Geothermal Energy Resources Act 1967, the Petroleum and Geothermal Energy Resources (Environment) Regulations 2012 and the Guidelines for the Preparation and Submission of an Environment Plan (DMP, 2012). Furthermore, the EP provides APA with a practical environmental management tool to be implemented as part of the drilling program. The objectives of the project EP are to: . Demonstrate compliance with relevant legislation. . Demonstrate that APA has a clear understanding of how the drilling program will interact with the environment. . Demonstrate that environmental impacts and risks are managed as low as reasonably practicable. . Demonstrate that APA has set appropriate performance objectives, standards and measurement criteria. . Ensure that systems are in place to minimise the environmental impacts associated with the drilling program. The purpose of this EP Summary is to provide information to the general public regarding environmental considerations and management requirements covered in the M9 Drilling and M1 P&A Environment Plan. . This summary document has been prepared in accordance with Regulation 11(7) of the Petroleum and Geothermal Energy Resources (Environment) Regulations 2012.

Mondarra 9 Drilling and Mondarra 1 Plug & Abandonment Program Environmental Plan Document Summary 3 DESCRIPTION OF THE ENVIRONMENT The M9 and M1 well locations are within the lease boundary of the Mondarra Storage Facility, within previously disturbed agricultural land in the Geraldton Sandplains IBRA region of the Perth Sedimentary Basin. The significant economic activities in the region include primary industries (agriculture and fisheries), oil and gas production, and broad hectare cropping and grazing activities. Other activities in the area include beekeeping and wildflower picking. The site experiences a typical southern Mediterranean climate of mild wet winters and hot dry summers. Site elevation is approximately 80 m Australian Height Datum (AHD), topography is gently undulating with elevation decreasing in a westerly direction between the MSF and the Brand Hwy. The project area is remote from sensitive environmental receptors including Environmentally Sensitive Areas (ESA’s) and areas of National Environmental Significance (NES). The MSF is located entirely within previously disturbed agricultural land. The site is not located within an Environmentally Sensitive Area (ESA). A small pocket of native vegetation is present within the M9 project area. The general condition of native vegetation present within the MSF lease area can be described as stressed, with the majority of individuals presenting discolouration and loss of foliage. Two site flora surveys of the MSF were undertaken during April and September 2006. The remnant vegetation surrounding the MSF was described as being dominated by menziesii, , Calothamnus blepharospermus and candelabroides over Baekea sp. Walkaway (P3), Eremaea beaufortioides, acicularis, Jacksonia nutans and Petrophile macrostachya intermixed with small shrubs Darwinia pauciflora and Hibertia hypercoides over Mesomelaena pseudostygia, Ecdeiocolea monostachya and grasses.” The majority of grasses recorded were introduced species reflecting the high degree of disturbance from cattle grazing activities. The surveys also identified three Priority 3 (P3) species; Baekea sp. Walkaway, polyanthema and Verticordia densiflora var. roseostella, all of which were recorded numerous times (>20) in the DPAW Florabase database. No Declared Rare Flora (DRF) were found. The small portion of remnant vegetation that will need to be cleared for the M9 drill pad has been reduced to the smallest areas possible through careful planning of the pad layout and will not significantly impact the regional floristic values. The MSF is not located in close proximity to any rivers, creeks or significant drainage lines. The nearest wetland is Ejarno Spring located approximately 1.5 km west of the site. Groundwater is present in an unconfined superficial aquifer overlying the Yarragadee formation. The water table is at approximately 31 m AHD adjacent the Gingin Scarp, decreasing in a westerly direction. A search of the Department of Indigenous Affairs (DIA) Aboriginal Heritage Inquiry System (AHIS) for heritage sites within close proximity to the MSF was undertaken and there were no registered heritage sites identified intersecting the MSF lease or access routes. In addition the DoE Protected Matters Search confirmed that the MSF and proposed drilling location do not intersect any registered World Heritage Properties or National Heritage Places. There is no significant native fauna habitat which could be impacted by the operations. Although protected fauna are known to reside within the broader region, the activity is within highly disturbed agricultural land and the activity takes place over a limited period, therefore impacts to native fauna are anticipated to be negligible.

Mondarra 9 Drilling and Mondarra 1 Plug & Abandonment Program Environmental Plan Document Summary 4 ENVIRONMENTAL HAZARDS AND CONTROLS An ERA addressing the environmental risks associated with the proposed M9 Drilling operations was held on the 30 July 2015. Prior to the workshop taking place, potential environmental aspects and impacts associated with M9 drilling operations were identified using the following sources of information: . DMP documents and guidelines for petroleum activities; . APPEA Code of Environmental Practice; . Specific documents describing MSF operations (i.e. well design basis documents, site layout drawings etc.); . The MSF OEP (MSF-PL-A-5002) . The Mondarra 6 & 7: Well Drilling Environmental Management Plan (MSF-PL-H-1005); . Previous personnel and contractor experience in drilling and gas facility environmental management. These were then risk assessed in addition to other aspects and impacts identified during the workshop. Furthermore, when the scope of the M1 P&A activities was added to the EP, the ERA assessment was subsequently revised with the M1 P&A well engineer in August 2015. It was found that no new environmental aspects could be identified that had not been adequately covered by the M9 ERA workshop. Table 4.1 below provides a summary of aspects and hazards associated with the project, along with preventative and mitigation controls that are implemented to manage the risk to As Low As Reasonably Practicable (ALARP).

Mondarra 9 Drilling and Mondarra 1 Plug & Abandonment Program Environmental Plan Document Summary 5 ENVIRONMENTAL MANAGEMENT The environmental management measures required under this EP will be implemented via the APA WA ISO14001 accredited integrated Health, Safety and Environmental Management System (APA HSEQ Management System) which comprises the following elements: . A corporate policy stating APA’s commitment to responsible environmental management; . Clearly stated objectives consistent with this commitment; . Clearly defined roles and responsibilities for personnel to indicate their obligations regarding environmental management; . Appropriate induction and training of personnel; . Monitoring and auditing programs to assess compliance with procedures and the achievement of objectives; . A system of reporting for recording data and notification of relevant personnel; and . Ongoing consultation to seek input from and inform all parties of relevant issues. The APA HSEQ Management System provides for the implementation of all of the requirements outlined in the project EP. The APA Hazard and Incident Reporting System forms part of the APA integrated HSEQ Management System and caters for the reporting, recording and follow up of all safety and environmental hazards and incidents. Personnel who observe, or are involved in a hazard or incident must complete report (APA HSE GP 07.01 T4) describing the circumstances that arose. Completed hazard and incident forms are sent to APA administrative personnel for entry into the APA hazard and incident database. Notification is then sent to the relevant Team Leader or Manager (who has thus far been verbally informed) for follow up and/or investigation if required. Reportable incidents are also forwarded to the Regulatory Manager for regulatory reporting. APA has a comprehensive database of procedures, forms and other guidance materials pertaining to environmental management (Available online at THE HUB). Additional site- specific documentation has also been developed as appropriate. Documents are available to all personnel via the company intranet.

Environmental management measures specific to the project are located in the Environmental Risk Assessment summary table, in section 4 of this document. Details of all chemicals and other substances in or added to any drilling fluids, treatment fluids or introduced into the Mondarra-9 and Mondarra-1 wells are provided Attachment A of this document, along with Material Safety Data Sheets (SDS) for each product to be used. 6 STAKEHOLDER CONSULTATION The following stakeholders have been identified as having an interest in MSF operations, and the associated M9 drilling and M1 P&A program and were consulted with throught the project planning: .

Liaison with the Shire of Irwin has been ongoing since construction of the Parmelia Pipeline in 1971 and will be maintained as part of the drilling program. . The Shire of Irwin was advised telephonically about the drilling of M9 in August 2015, and it was confirmed that approvals for some of the infrastructure will be required. These applications are to be prepared and approval received before drilling can commence. . The DFES Dongara Emergency Service Unit has been identified as the primary contact in the event of an emergency situation at the MSF or during associated drilling activities. Regular contact is maintained with DFES in Dongara and records of correspondence undertaken are maintained. In addition, DFES is involved in relevant emergency response exercises at the MSF and other locally operated APA facilities. Section 22C and 25A exemptions are in place, covering the operations. . Alert Disaster Control has been engaged by APA to assist in responding to well blow outs at the MSF and this will be extended for the drilling program. A contract is in place and relevant contact details provided in the MSF ER Plan. . Landholders with properties intersecting the MSF lease and the MSF access track are contacted at least annually by APA as part of an ongoing community consultation program for its operating assets. Additional consultation was also undertaken throughout recent site expansion works. . APA has a long history of positive relations with landholders impacted by the MSF which has been ongoing since the construction of the Parmelia Pipeline in 1971. . The owner of Lot M356 was specifically consulted in regards to the upcoming drilling program and signed an agreement relating to required vegetation disturbance for the project. Stakeholder will be kept up to date on progress and any unforeseen changes to the proposal including delays to the commencement or completion of the activity. APA will continue to consult with the relevant government authorities, neighbouring farms and interested persons regarding project activities prior to site mobilisation and throughout the life of the project. Ongoing consultation will be maintained with any interested stakeholders and APA shall promptly track and response to any queries or complaints associated with this or any of its operations, in line with the APA Land Management Plan (320-PL-HEL-0001).

16. OTHER INFORMATION

Additional information WORKPLACE CONTROLS AND PRACTICES: Unless a less toxic chemical can be substituted for a hazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary.

RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES: The recommendation for protective equipment contained within this report is provided as a guide only. Factors such as method of application, working environment, quantity used, product concentration and the availability of engineering controls should be considered before final selection of personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE: It should be noted that the effects from exposure to this product will depend on several factors including: frequency and duration of use; quantity used; effectiveness of control measures; protective equipment used and method of application. Given that it is impractical to prepare a ChemAlert report which would encompass all possible scenarios, it is anticipated that users will assess the risks and apply control methods where appropriate.

11.1 Information on toxicological effects Health hazard May be harmful. This product has the potential to cause adverse health effects with over exposure. Use safe summary work practices to avoid eye or skin contact and inhalation. Some individuals are hypersensitive to sulphites and may experience respiratory problems following exposure. Individuals known to be hypersensitive or with existing respiratory problems (eg asthma) are advised to avoid exposure. Eye Low irritant. Contact may result in irritation, lacrimation, pain, redness, conjunctivitis and possible corneal damage. Inhalation Low irritant. Over exposure may result in mucous membrane irritation of the respiratory tract, with coughing. Some individuals are hypersensitive to sulphites, and may experience asthma like symptoms (wheezing and shortness of breath) immediately following exposure. Skin Low irritant. Contact may result in irritation, redness, rash and dermatitis. Ingestion May be harmful. Ingestion may result in gastrointestinal irritation, nausea and vomiting. Well tolerated due to the oxidation of sulphites in the body to sulphates, however with large quantities sulphurous acid is formed. Some individuals may have an allergic reaction.

16. OTHER INFORMATION

Additional information RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

WORKPLACE CONTROLS AND PRACTICES: Unless a less toxic chemical can be substituted for a hazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary.

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES: The recommendation for protective equipment contained within this report is provided as a guide only. Factors such as method of application, working environment, quantity used, product concentration and the availability of engineering controls should be considered before final selection of personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE: It should be noted that the effects from exposure to this product will depend on several factors including: frequency and duration of use; quantity used; effectiveness of control measures; protective equipment used and method of application. Given that it is impractical to prepare a ChemAlert report which would encompass all possible scenarios, it is anticipated that users will assess the risks and apply control methods where appropriate.

11. TOXICOLOGICAL INFORMATION

Health Hazard Harmful - irritant. This product has the potential to cause adverse health effects with over exposure. Summary Use safe work practices to avoid eye or skin contact and inhalation. At room temperature ethylene glycol has a low vapour pressure and therefore an inhalation hazard is not anticipated unless heated or sprayed. Chronic exposure may result in kidney and central nervous system (CNS) damage. Eye Irritant. Contact may result in irritation, lacrimation, pain and redness. Inhalation Harmful. Over exposure may result in mild respiratory irritation. High level exposure may result in headache, nausea, dizziness and central nervous system (CNS) depression. Due to the low vapour pressure, an inhalation hazard is not anticipated with normal use. Skin Irritant. Contact may result in drying and defatting of the skin, rash and dermatitis. Ingestion Harmful. Ingestion may result in nausea, vomiting, abdominal pain, diarrhoea, drowsiness and unconsciousness. Chronic exposure may result in kidney damage. Aspiration may result in chemical pneumonitis and pulmonary oedema.

16. OTHER INFORMATION

Additional information ETHYLENE GLYCOL: Has been reported to cause teratogenic and mutagenic effects, however the doses recorded for these effects are extremely high. For example experimental rat studies by the oral route have shown that ingestion of 8.5 g/kg by pregnant rats in their 6-15 day of gestation caused teratogenic effects. This equates to the ingestion of 500 ml of ethylene glycol by a 60 kg women for similar effects to occur. Exposure at such levels is not reported in industry.

RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

STORAGE OF COMBUSTIBLE LIQUIDS. Combustible liquids with a flash point between 61°C and 150°C are required to be stored as for flammable liquids (Dangerous Goods Class 3) under AS 1940. [Refer to Australian Standard 1940, Storage and Handling of Flammable and Combustible Liquids, for full storage guidelines].

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES: The recommendation for protective equipment contained within this report is provided as a guide only. Factors such as method of application, working environment, quantity used, product concentration and the availability of engineering controls should be considered before final selection of personal protective equipment is made.

16. OTHER INFORMATION Additional ETHYLENE GLYCOL: Has been reported to cause teratogenic and mutagenic effects, however the doses Information recorded for these effects are extremely high. For example experimental rat studies by the oral route have shown that ingestion of 8.5 g/kg by pregnant rats in their 6-15 day of gestation caused teratogenic effects. This equates to the ingestion of 500 ml of ethylene glycol by a 60 kg women for similar effects to occur. Exposure at such levels is not reported in industry.

RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

16. OTHER INFORMATION

Additional information EXPOSURE STANDARDS - TIME WEIGHTED AVERAGES: Exposure standards are established on the premise of an 8 hour work period of normal intensity, under normal climatic conditions and where a 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants. In the following circumstances, exposure standards must be reduced: Strenuous work conditions; hot, humid climates; high altitude conditions; extended shifts (which increase the exposure period and shorten the period of recuperation).

RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

16. OTHER INFORMATION

Additional information RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

WORK PRACTICES - SOLVENTS: Organic solvents may present both a health and flammability hazard. It is recommended that engineering controls should be adopted to reduce exposure where practicable (for example, if using indoors, ensure explosion proof extraction ventilation is available). Flammable or combustible liquids with explosive limits have the potential for ignition from static discharge. Refer to AS 1020 (The control of undesirable static electricity) and AS 1940 (The storage and handling of flammable and combustible liquids) for control procedures.

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES: The recommendation for protective equipment contained within this report is provided as a guide only. Factors such as method of application, working environment, quantity used, product concentration and the availability of engineering controls should be considered before final selection of personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE: It should be noted that the effects from exposure to this product will depend on several factors including: frequency and duration of use; quantity used; effectiveness of control measures; protective equipment used and method of application. Given that it is impractical to prepare a ChemAlert report which would encompass all possible scenarios, it is anticipated that users will assess the risks and apply control methods where appropriate.

16. OTHER INFORMATION

Additional information RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGE (TWA) or WES (WORKPLACE EXPOSURE STANDARD) (NZ): Exposure standards are established on the premise of an 8 hour work period of normal intensity, under normal climatic conditions and where a 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants. In the following circumstances, exposure standards must be reduced: strenuous work conditions; hot, humid climates; high altitude conditions; extended shifts (which increase the exposure period and shorten the period of recuperation).

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES: The recommendation for protective equipment contained within this report is provided as a guide only. Factors such as method of application, working environment, quantity used, product concentration and the availability of engineering controls should be considered before final selection of personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE: It should be noted that the effects from exposure to this product will depend on several factors including: frequency and duration of use; quantity used; effectiveness of control measures; protective equipment used and method of application. Given that it is impractical to prepare a ChemAlert report which would encompass all possible scenarios, it is anticipated that users will assess the risks and apply control methods where appropriate.

16. OTHER INFORMATION

Additional information RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGES: Exposure standards are established on the premise of an 8 hour work period of normal intensity, under normal climatic conditions and where a 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants. In the following circumstances, exposure standards must be reduced: Strenuous work conditions; hot, humid climates; high altitude conditions; extended shifts (which increase the exposure period and shorten the period of recuperation).

Additional information The manufacturer indicates the product is mixture of 30-50% Hexanedinitrile, 5-20% Hydrochloric acid (as pH corrector) and water. Hydrochloric acid is used to neutralise hexanedinitrile to become the salt with slightly alkali (pH 9-11).

AMINE: CAUTION THIS PRODUCT CONTAINS AN AMINE. DO NOT ADD NITRITES or other NITROSATING AGENTS to this product due to the potential for NITROSAMINE formation. Nitrosamines are potent carcinogens and some have been shown to cause severe acute (heart, brain, blood, liver - kidney) damage as well as chronic effects (reproductive effects, liver - lung and kidney tumours).

RESPIRATORS: In general the use of respirators should be limited and engineering controls employed to avoid exposure. If respiratory equipment must be worn ensure correct respirator selection and training is undertaken. Remember that some respirators may be extremely uncomfortable when used for long periods. The use of air powered or air supplied respirators should be considered where prolonged or repeated use is necessary.

EXPOSURE STANDARDS - TIME WEIGHTED AVERAGE (TWA) or WES (WORKPLACE EXPOSURE STANDARD) (NZ): Exposure standards are established on the premise of an 8 hour work period of normal intensity, under normal climatic conditions and where a 16 hour break between shifts exists to enable the body to eliminate absorbed contaminants. In the following circumstances, exposure standards must be reduced: strenuous work conditions; hot, humid climates; high altitude conditions; extended shifts (which increase the exposure period and shorten the period of recuperation).

PERSONAL PROTECTIVE EQUIPMENT GUIDELINES: The recommendation for protective equipment contained within this report is provided as a guide only. Factors such as method of application, working environment, quantity used, product concentration and the availability of engineering controls should be considered before final selection of personal protective equipment is made.

HEALTH EFFECTS FROM EXPOSURE: It should be noted that the effects from exposure to this product will depend on several factors including: frequency and duration of use; quantity used; effectiveness of control measures; protective equipment used and method of application. Given that it is impractical to prepare a ChemAlert report which would encompass all possible scenarios, it is anticipated that users will assess the risks and apply control methods where appropriate.

11. TOXICOLOGICAL INFORMATION

Principle Route of Exposure Eye or skin contact, inhalation.

Sympotoms related to exposure Acute Toxicity Inhalation Inhaled crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (IARC, Group 1). There is sufficient evidence in experimental animals for the carcinogenicity of tridymite (IARC, Group 2A).

Breathing silica dust may cause irritation of the nose, throat, and respiratory passages. Breathing silica dust may not cause noticeable injury or illness even though permanent lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chronic Effects/Carcinogenicity" subsection below).

Eye Contact May cause eye irritation. Skin Contact May cause mechanical skin irritation. Ingestion None known

TUNED SPACER E+ Page 4 of 7 Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, wheezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung cancer in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of tridymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2).

There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

11. TOXICOLOGICAL INFORMATION

Principle Route of Exposure Eye or skin contact, inhalation.

Sympotoms related to exposure Inhalation Inhaled crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (IARC, Group 1). There is sufficient evidence in experimental animals for the carcinogenicity of tridymite (IARC, Group 2A).

Breathing silica dust may cause irritation of the nose, throat, and respiratory passages. Breathing silica dust may not cause noticeable injury or illness even though permanent lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See Chronic Effects/Carcinogenicity" subsection below). "

Skin Contact Can dry skin. May cause an allergic skin reaction. May cause alkali burns with confined contact.

Eye Contact May cause severe eye irritation.

Ingestion None known

Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust.

CEMENT - CLASS G + 35% SSA-1 Page 4 of 7 Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, wheezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung cancer in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of tridymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2).

" There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

Other Information For further information consult Adverse Effects of Crystalline Silica Exposure" published by the American Thoracic Society Medical Section of the American Lung Association, American Journal of Respiratory and Critical Care Medicine, Volume 155, pages 761-768 (1997)."

11. TOXICOLOGICAL INFORMATION

Principle Route of Exposure Eye or skin contact, inhalation.

Sympotoms related to exposure Inhalation Inhaled crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (IARC, Group 1). There is sufficient evidence in experimental animals for the carcinogenicity of tridymite (IARC, Group 2A).

Breathing silica dust may cause irritation of the nose, throat, and respiratory passages. Breathing silica dust may not cause noticeable injury or illness even though permanent lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chronic Effects/Carcinogenicity" subsection below).

Skin Contact Can dry skin. May cause an allergic skin reaction. May cause alkali burns with confined contact.

Eye Contact May cause severe eye irritation.

Ingestion None known

Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust.

CEMENT - CLASS G Page 4 of 7 Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, wheezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung cancer in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of tridymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2).

There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

11. TOXICOLOGICAL INFORMATION

Principle Route of Exposure Eye or skin contact, inhalation.

Inhalation Inhaled crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (IARC, Group 1). There is sufficient evidence in experimental animals for the carcinogenicity of tridymite (IARC, Group 2A).

Breathing silica dust may cause irritation of the nose, throat, and respiratory passages. Breathing silica dust may not cause noticeable injury or illness even though permanent lung damage may be occurring. Inhalation of dust may also have serious chronic health effects (See "Chronic Effects/Carcinogenicity" subsection below).

Skin Contact None known.

Eye Contact May cause mild eye irritation.

Ingestion May produce nervous system effects such as feeling of weakness, unsteady walk, and dilation of blood vessels. May affect the heart and cardiovascular system.

Aggravated Medical Conditions Individuals with respiratory disease, including but not limited to asthma and bronchitis, or subject to eye irritation, should not be exposed to quartz dust.

BARITE Page 4 of 7 Chronic Effects/Carcinogenicity Silicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling, and sometimes-fatal lung disease called silicosis. Symptoms include cough, shortness of breath, wheezing, non-specific chest illness, and reduced pulmonary function. This disease is exacerbated by smoking. Individuals with silicosis are predisposed to develop tuberculosis.

Cancer Status: The International Agency for Research on Cancer (IARC) has determined that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources can cause lung cancer in humans (Group 1 - carcinogenic to humans) and has determined that there is sufficient evidence in experimental animals for the carcinogenicity of tridymite (Group 2A - possible carcinogen to humans). Refer to IARC Monograph 68, Silica, Some Silicates and Organic Fibres (June 1997) in conjunction with the use of these minerals. The National Toxicology Program classifies respirable crystalline silica as "Known to be a human carcinogen". Refer to the 9th Report on Carcinogens (2000). The American Conference of Governmental Industrial Hygienists (ACGIH) classifies crystalline silica, quartz, as a suspected human carcinogen (A2).

There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by scarring of the lungs, skin, and other internal organs) and kidney disease.

Prolonged inhalation of fine barium sulfate dusts form harmless nodular granules in lung, an affliction called baritosis. Baritosis produces no symptoms of bronchitis or emphysema, and lung functioning is not affected although dyspnea, upon exertion, may occur. The nodulation disappears if exposure is stopped.
