1 Introduction On 27 November 2018, Santos completed its acquisition of Quadrant Energy. This has the effect that Santos Limited is now the ultimate holding company of Quadrant Energy Holdings Pty Ltd and its subsidiaries. It has also resulted in most of the Quadrant group of entities changing their name. For example, Quadrant Energy Australia Limited has changed its name to Santos WA Energy Limited and Quadrant Northwest Pty Ltd has changed its name to Santos WA Northwest Pty Ltd. Each entity’s ABN has remained the same. Santos WA Energy Limited on behalf of Santos WA Northwest Pty Ltd and Santos WA Southwest Pty Limited (hereafter referred to as Santos WA or Company) will be responsible for all commitments and obligations in this EP.

3 Description of Activity

3.1 Varanus Island

Varanus Island (VI) forms the central gathering and processing hub for the Santos WA oil and gas production facilities in the area. Gas and liquids from the offshore facilities are processed on the island (refer Figure 2-3). The onshore facilities include the control centre and systems to remotely control and monitor the normally unmanned offshore facilities. The accommodation, administration and operating centre for the various production facilities are also located on VI. All facilities that form part of the Varanus Island Hub are operated and maintained from VI. Personnel reside on VI and travel to and from the offshore facilities on a regular basis via helicopter or support vessel. An overview of the types of activities that support operations at the VI Hub facilities, and covered by this EP, are briefly described in Table 3-1. Table 3-1: Activities that Support Varanus Island Operations Activity Brief Description Routine operations and maintenance (onshore and offshore) Daily inspections/ checks Vessels, instruments, valving, sumps and drains Hydrotesting and isolation Pipelines and production equipment Critical function testing Including systems such as the firewater deluge system Intervention activities/ Isolations Valves, rotating equipment, instrumentation, vessels and topsides flowlines for maintenance / project / drilling activities Inspection/Maintenance/Monitoring Cutting, grinding, welding, testing, paint removal (water/grit blasting) and Repair activities and painting activities Inspection and maintenance of wellheads; storage tanks, pressure equipment and piping (including hydrocarbon freeing) and infrastructure in sub-tidal zone (e.g. pipelines and wharfs) Bund liner inspection and repairs Civil works To support ongoing repair, maintenance and brownfield modifications Transport Support vessel and helicopter operations between the mainland, VI, AI and the offshore facilities Transport of personnel and equipment/goods by helicopter, vessel or vehicles to onshore and offshore locations Flushing, cleaning, purging and Undertaken on process vessels and pipelines (flowlines), including pipeline pigging facilities topside cleaning Well suspension and intervention Including coil tubing, wireline (e.g. eline & Slickline), hydraulic work activities over (e.g. snubbing) and pumping Brownfield modifications and To static / rotating equipment, process, electrical, instrumentation and upgrades utility systems Marine Activities Unloading / back loading support Activities at the Varanus Island wharves and offshore facilities (e.g. vessels transport of chemicals and fuel on platforms), clearance of sediment/debris build up around wharves and ramps to maintain safe vessel/roll on roll off access.

Activity Brief Description Contaminated Sites Remediation Contaminated site investigation and remediation activities include Activities construction, installation and commissioning of equipment and infrastructure for the purpose of recovery of contamination and monitoring and sampling/taking of groundwater, vapour and soil, to be conducted in both on-lease and off-lease areas.

3.2 Airlie Island

The facilities on AI are drained of any hydrocarbons. The type of care and maintenance activities that take place at the AI facilities include:

+ Transport of personnel and equipment/goods by vessel to the island; + Visual inspection of Chervil pipeline; + Inspection of communication equipment on Airlie Island; + Inspection and removal of weather damaged facilities/equipment; and + Environmental monitoring. At AI a dingy is deployed from the support vessel to access the island, if required, as there is no wharf to accommodate larger vessels. If a barge is used to transport equipment to AI for maintenance activities, the barge may be stranded on the beach for offloading and onloading of personnel and equipment.

There are four subsea pipelines associated with Airlie Island (these are all suspended and flooded with seawater):

+ A 200mm NB production flowline from the Chervil monopod to AI; + An 80mm NB gas-lift line to the Chervil monopod from AI; + A 500mm NB crude oil export pipeline from AI to the tanker mooring; and + The 200mm NB South Pepper pipeline.

3.3 Activities not included under this EP

Decommissioning will be carried out at the end of the Facility life, in accordance with relevant legislation at that time. Decommissioning activities will be the subject of separate approval processes and are not part of the scope of this EP. The platforms, subsea installations and pipelines located in Commonwealth waters are covered by the Varanus Island Hub Commonwealth EP, and are outside of the scope of this EP.

4 Description of the Environment While the area impacted by the planned activity is limited to the immediate vicinity of the facilities, an unplanned worse case credible hydrocarbon release has been modelled to illustrate potential impacts to a wider area. The wider environment that may be affected (EMBA) by the potential spill is the spatial extent considered when discussing the sensitivities and receptors of the existing environment.

4.1 Regional Setting

The operational area is located within the Northwest Shelf Province, as defined under the Integrated Marine and Coastal Regionalisation of Australia (IMCRA) Version 4.0. The operational area occurs in shallow-water tropical marine ecosystems with high species richness. Most of the region’s species are tropical and are also found in other parts of the Indian and western Pacific oceans. The EMBA overlaps five IMCA provincial bioregions including the Northwest Transition, Northwest Province, Northwest Shelf Province, Central Western Transition and Central Western Shelf Transition. The southern part of the EMBA is a transition zone between tropical and temperate waters and includes the northern extent of the ranges of some temperate species that are more typical of the South-west Marine Region. High diversity is partly driven by the interaction between seafloor features and the currents of the region. The interaction of seafloor features and oceanographic processes also supports unique ecosystems and associated trophic interactions and communities (DSEWPaC, 2012). Key features of the EMBA are the Ningaloo Reef and North West Cape to the southwest of the monopod, the Montebello/Barrow/ to the north east of the monopod and the Dampier Archipelago/Burrup Peninsula to the north east of the monopod. Barrow Island, the Montebello Islands, Lowendal Islands including VI, Airlie Island are part of a shallow submarine ridge, which extends north from the mainland near Onslow. The ridge contains extensive areas of intertidal and shallow subtidal limestone pavement surrounding the numerous, mostly small islands which are found in the region. The seabed is primarily less than 5 m deep and consists of sand veneered limestone pavement with patches of fringing coral reef. In addition to the mainland area surrounding Cape Range, key values of this subregion include Exmouth Gulf Islands, Muiron Islands, Lowendal Islands, Montebello Islands and Barrow Island.

4.2 Benthic Habitats

The benthic habitats within waters in the operational area lie at depths ranging from shoreline to 40 m. Benthic habitats within the operational area consist of coral reefs, seagrasses and macroalgae, which are associated with hard substrate around the Montebello and Lowendal Islands, as well as the mainland shore (Cardno 2011, Chevron 2005). However, the majority of the seabed habitat within the operational area is relatively devoid of hard corals, with coral outcrops being sparsely distributed (Cardno 2011). Seagrasses within the operational area are small ephemeral species, sparsely interspersed between macroalgae, that grow on soft sediments, subtidal sands and in intertidal pools (Chevron 2005). The seafloor along the sales gas pipeline between Varanus Island and the mainland comprises calcareous sandy sediments with scattered sponges, algae, sea whips, soft corals and occasionally hard corals (LEC 1990). The habitat of the sales gas pipeline is widely distributed throughout the region. Saline mudflats occur where the sales gas pipeline occurs on-shore.

Dominant shoreline habitats within the remainder of the operational area include widely spread mangroves, and sandy beaches interspersed with hard substrate and intertidal platforms, which provide breeding and nesting grounds for marine turtles and seabirds (Astron 2012, Garnet and Crowley 2000).

Mangroves occur as discrete patches within the tidal and supratidal (immediately above the high tide mark) zone on the west coast of VI at South Mangrove Beach and in a small embayment directly adjacent to West Wharf (Astron 2012).

Santos Ltd | EA-60-RI-00176.01 Page 15 of 97

The terrestrial habitats within the operational area include Varanus Island, Airlie Island and the onshore pipeline. The vegetation on Varanus Island and Airlie Island is broadly described as ‘desertic’ dominated by hummock grasslands, with much of the vegetation disturbed to some degree (weeds) (Astron 2013). The mainland portion of the sales gas pipeline is dominated by sand dunes and grass savannas (Dames and Moore 1998). Table 4-1 and Figure 4-1 provide an overview of the benthic habitats surrounding the operational area and within the EMBA.

Table 4-2 and shown in Error! Reference source not found.. Part of the operational area intersects the Montebello Australian Marine Park (AMP). AMPs are recognised under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) for protecting and maintaining biological diversity and contributing to a national representative network of marine protected areas. Management plans for AMPs have been developed and came into force on 1 July 2018. Under these plans AMPs are allocated conservation objectives (International Union for Conservation of Nature (IUCN) Protected Area Category) based on the Australian IUCN reserve management principles in Schedule 8 of the EPBC Regulations 2000. The operational area also intersects the Montebello Islands Marine Park (State waters) and Barrow Island Marine Management Area, which also represent a National Heritage Area (Barrow Island and the Montebello-Barrow Island Marine Conservation Reserves). There is a management plan in place for the Montebello/Barrow Islands (DEC, 2007). Socio-economic values of the Montebello and Barrow Islands MCR include hydrocarbon exploration and production, pearling, nature-based tourism, commercial and recreational fishing, water sports, European history and maritime heritage and scientific research (DEC, 2007).

4.4 Threatened and Migratory Fauna

The EPBC Act lists threatened and migratory fauna species that are protected under Commonwealth legislation and various international conventions and treaties. A search of the EPBC Act Protected Matters Database was conducted using the coordinates of the EMBA to identify these species. Table 4-3: Summary of Protected Species and Communities within the Operational Area and EMBA Value Description Fish and sharks  14 species of fish and sharks listed as threatened and/or migratory under the EPBC Act could occur within the EMBA (9 of which could occur within the operational area) Marine Reptiles  6 marine reptile species could occur within the operational area and EMBA (5 turtle species, 1 seasnake) that are listed as threatened and/or migratory under the EPBC Act  The following Biologically Important Areas (BIAs) intersect the operational area: - Internesting (interesting buffer) (loggerhead, green, hawksbill and flatback turtles) - Basking (green turtle) - Foraging (hawksbill, green, loggerhead and flatback turtles) - Nesting (hawksbill, green, loggerhead and flatback turtles) - Mating (green, hawksbill and flatback turtles).  Habitat mapped as ‘habitat critical (nesting)’ for green, hawksbill and flatback turtles also occur within the operation area. Nesting is also known to occur on Varanus and Airlie Islands. Marine Mammals  12 species of marine mammals listed as threatened and/or migratory under the EPBC Act could occur within the EMBA (8 of which could occur within the operational area)  The following BIAs intersect the operational area: - Migration (humpback whale) - Distribution (pygmy blue whale).  A number of marine mammals are known to occur in the local region around the EMBA, including dolphins, whales and the dugong. Some species are seasonal visitors, migrating through NWS waters, while others occur all year round. Seabirds  58 species of birds listed as threatened and/or migratory under the EPBC Act could occur within the EMBA (25 of which could occur within the operational area).  Breeding BIAs intersect the operational area for the following species; wedge-tailed shearwater, Australian fairy tern, lesser crested tern, white- tailed tropicbird and roseate tern.  Seabird colonies and nesting sites (primarily for the wedge-tailed shearwater) occur on Varanus and Airlie Islands. Terrestrial /  8 fauna listed as threatened and/or migratory under the EPBC Act could Subterranean occur within the terrestrial environments of the operational area and/or Fauna EMBA, and have the potential to be impacted by planned or unplanned activities (2 subterranean fish, 3 mammals and 3 reptiles).

5 Stakeholder Consultation Stakeholders, identified in Table 5-1, were provided a VI Hub Operations Consultation Package via email in June 2018 to ensure they were aware the EP was being revised. In addition, Santos WA’s wider stakeholder group is regularly updated on Santos’ activities through Quarterly Consultation Update documents, which list the VI Hub as a key operating facility for Santos WA. Outside of the regulatory approval process, Santos WA continuously engages with regional stakeholders to maintain a social licence to operate. Santos WA maintains relationships with community partners, focussing on the Karratha and Exmouth communities, allowing the business to align community investments with the strategic objectives of the communities in which Santos WA operates. Other interested stakeholders are able to find information regarding the VI Hub in a fact sheet published on Santos WA’s external website. Santos WA considers that consultation with regulators and key stakeholders has been adequate for activities covered under this EP. No stakeholder has objected to activities covered under this EP nor claimed that the environmental impacts or risks are unacceptable. Given the long term presence at VI, Santos WA anticipates all relevant stakeholders are familiar with the facility. For the activities undertaken under this EP, a standardised approach is applied to identify key stakeholders for the activity in question, beginning with a review of Santos’ stakeholder list, and of the stakeholders consulted over other recent activities in the area. In particular, the operational area for the activity is used to identify relevant persons and will be used throughout the duration of this EP.

5.1 Addressing consultation feedback

Santos WA’s Consultation Coordinator is available before, during and after the activity to ensure opportunities for stakeholders to provide feedback are available. Consultation material is provided to relevant internal, activity personnel to ensure the Santos WA business has a thorough understanding of how the activity is being received by relevant persons. If in stakeholder consultation a change to any control measure or activity outlined in this EP is required, Santos WA would undertake an internal assessment using the management of change (MoC) process.

6 Environmental Hazards and Controls

6.1 Overview of process

Santos WA operates under an overarching risk management policy (QE-91-IF-10050). The company risk management framework (QE-91-IF-10051) underpins the risk management policy and is consistent with the requirements of AS/NZS ISO 31000:2018 Risk Management – Guidelines (ISO, 2018).

The key steps to risk management are illustrated in Figure 6-1.

Describe the activity and identiy the hazards (planned and unplanned events) arising from the activity

Identify receptors in the environment that will, or may be impacted by the event and determine the nature and scale of impacts

Apply standard control measures

Assess impacts (planned events (based on consequences only)) and risks (unplanned events (based on likelihood and consequence)) with standard controls applied

Treat risks and impacts by implementing additional controls as needed

Determine residual impact and risk ranking and ensure activity is ALARP and Acceptable.

Figure 6-1: Environmental impact and risk assessment process

Santos WA has undertaken environmental impact and risk assessments for the operational activities planned events (including any routine, non-routine and contingency activities) and unplanned events in accordance with the P(SL)(E)R 2012. The extent of actual or potential impacts from each planned or unplanned event is assessed using, where required, modelling (e.g., hydrocarbon spills) and scientific reports. The duration of the event is

Santos Ltd | EA-60-RI-00176.01 Page 30 of 97

also described, including the potential duration of any impacts should they occur. For each planned and unplanned event, a set of Environmental Performance Objective(s), Control Measures, Environmental Performance Standards and Measurement Criteria are identified. The definitions of the performance objectives, environmental performance standards and measurement criteria are consistent with PSL(E)R 2012.

Impact mechanisms and any thresholds for impacts are determined and described, using scientific literature and modelling where required. Impact thresholds for different critical life stages are also identified where relevant. The consequence level of the impact is then determined for each planned and unplanned event based on the severity of the impact to relevant receptors.

This process determines a consequence level based on set criteria for each receptor category and takes into consideration the duration and extent of the impact, receptor recovery time and the effect of the impact at a population, ecosystem or industry level. The consequence definitions are outlined in Table 6-1.

Table 6-1: Consequence level description Consequence Consequence Level Description Level A Negligible No impact or negligible impact. Environmental impact lasting days up to 1 week. B Minor Detectable but insignificant change to local population, industry or ecosystem factors. Environmental impact lasting weeks up to 12 months. C Moderate Significant impact to local population, industry or ecosystem factors. Environmental impact lasting 1 to 10 years. D Major Major long-term effect on local population, industry or ecosystem factors. Environmental impact lasting 10 to 20 years. E Critical Complete loss of local population, industry or ecosystem factors AND/ OR major wide-spread regional impacts with slow recovery to no full recovery. Environmental impact lasting more than 20 years to no recovery. Note: Injury or mortality to a protected species is included as a moderate consequence level

For unplanned events, in addition to the consequence level of the impact, a risk ranking is also determined using an assessment of the likelihood (likelihood ranking) of the impact occurring from an unplanned event. For oil spill events, potential impacts to environmental receptors are assessed where they occur within the EMBA using results from modelling. The Santos WA risk matrix is provided in Table 6-2.

6.2 ALARP and Acceptability Evaluation

For planned and unplanned events, an ALARP assessment is undertaken to demonstrate that the standard control measures adopted reduce the impact (consequence level) or risk to as low as reasonably practicable (ALARP). This process relies on demonstrating that further potential control measures would require a disproportionate level of cost/effort in order to reduce the level of impact or risk. If this cannot be demonstrated, then further control measures are adopted. The level of detail included within the ALARP assessment is based upon the nature and scale of the potential impact or risk. For example, more detail is required for a risk ranked as ˋMedium’ compared to a risk ranked as ˋLow’.

Santos WA considers an impact or risk associated with the proposed activity to be acceptable if the following criteria are met:

+ The consequence of a planned event is ranked as A or B; or a risk of impact from an unplanned event is ranked low to medium;

Santos Ltd | EA-60-RI-00176.01 Page 32 of 97

+ An assessment has been completed to determine if further information/studies are required to support or validate the consequence assessment; + Assessment and management of risks has addressed the principles of ecologically sustainable development (ESD); + That the acceptable levels of impact and risks have been informed by relevant species recovery plans, threat abatement plans and conservation advice can be demonstrated; + Performance standards are consistent with legal and regulatory requirements; + Performance standards are consistent with the Santos WA’s Environmental Management Policy; + Performance standards are consistent with industry standards and best practice guidance (e.g., National Biofouling Management Guidelines for the Petroleum Production and Exploration Industry (Marine Pest Sectoral Committee, 2018)); + Performance outcomes and standards are consistent with stakeholder expectations; and + Performance standards have been demonstrated to reduce the impact or risk to ALARP.

6.3 Summary of Risks

Table 6-3 and Table 6-4 summarise the identified hazards and the final consequence ranking (for planned events) and residual risk ranking (for unplanned events) respectively. Planned and unplanned events are all considered acceptable using Santos consequence ranking process. Table 6-5 summarises the potential impacts, risks and control measures for planned events and Table 6-6 summarises the potential impacts, risks and control measures for unplanned events.

7 Management Approach The VI Hub operations activities will be managed in accordance with the Santos WA Environmental Management Policy and with all measures and controls detailed within the EP accepted by DMIRS.

The objective of the EP is to ensure that potential adverse environmental impacts from planned and unplanned events associated with the activity are identified and assessed, and to stipulate mitigation measures to avoid and/or reduce any adverse impacts to the environment to ALARP and acceptable levels.

The EP details specific performance objectives, standards and procedures, and identifies the range of controls to be implemented (consistent with the standards) to achieve the performance outcomes. The EP also identifies the specific measurement criteria and records to be kept to demonstrate the achievement of each performance outcome.

As described in the EP, the implementation strategy includes the relevant details of the following:

 Environmental Management System;  Environmental Management Policy;  Hazard identification, risk and impact assessment and controls;  Environmental performance objectives, control measures and performance standards;  Leadership, accountability and responsibility;  Workforce training and competency;  Maintenance management system;  Emergency preparedness and response;  Incident reporting, investigation and follow-ups;  Document management; and  Audits and inspections. During the period of the activity described in the EP being undertaken, Santos will ensure environmental performance is monitored and managed through an inspection and monitoring regime undertaken by Santos representatives or delegates. During an activity, frequent HSE inspections will be conducted to verify compliance against selected environmental performance objectives and standards of the EP. Any in-field opportunities for improvement or corrective actions will be discussed during the inspection with the work area supervisor and/or crew and may also be entered into the action tracking management system until closed out, as for non-conformance actions. Inspection reports will be distributed to Santos WA’s relevant personnel (e.g. operations superintendent, Santos WA on-board representatives), and HSE Department representatives, for review. EP non-conformances will be addressed and resolved by a systematic corrective action process as outlined in Santos WA’s Assurance Standard. Non-conformances arising from audits and inspections will be entered into Santos WA’s incident and action tracking management system (i.e. ‘Enablon’). Once entered, corrective actions, time frames and responsible persons (including action owners and event validators) will be assigned. Corrective action ‘close out’ will be monitored using a management escalation process.

Environmental recordable and reportable incidents will be reported to DMIRS, and other regulators as required. The incident reporting requirements will be provided to all crew on board the facilities and support vessels with special attention to the reporting time-frames to provide for accurate and timely reporting.

8 Hydrocarbon Spill Response Arrangements The risk assessment for the activity has identified credible spill scenarios as provided in Table 8-1 below. The worst-case spill, requiring the greatest potential level of response in an offshore/nearshore environment is a surface release from a vessel collision (8,629 m3 of VI crude blend) and in an onshore environment is a loss of containment from storage tanks (39,750 m3). Table 8-1: Summary of Maximum Credible Spill (MCS) Scenarios Maximum MCS Scenario Hydrocarbon Types Credible Volume Diesel 329 m3 Surface release from vessel collision HFO 1,900 m3 VI crude blend 8,629 m3 Surface release of diesel from bunker transfer Diesel 15 m3 Linda, Lee and Rose 521 m3 Loss of well control producing assets condensate Bambra crude* 121 m3 Wonnich condensate 270 m3 Harriet crude* 121 m3 Loss of well control non-producing assets Simpson crude* 41 m3 Agincourt crude 109 m3 Double Island crude* 46 m3 John Brookes 210 m3 condensate Loss of integrity/damage resulting in pipeline release* John Brookes 56 m3 condensate – *Wonnich, Campbell/Sinbad, Gypsy, Simpson, Victoria, shoreline crossing Double Island and Gibson pipelines have been flushed 3 with treated seawater therefore no credible hydrocarbon Halyard condensate 16 m spill scenario. Harriet crude 13 m3 Agincourt crude 10 m3 VI crude blend 39,750 m3 Onshore release from storage tanks/pipelines and Diesel 2 m3 hydrocarbon processing VI crude blend 115 m3

The VI OPEP (EA-60-RI-00186.02) was last accepted by DMIRS on 21 July 2017, is due for resubmission and reassessment prior by 21 January 2020. It is considered fit for purpose for the activity and will be referred to in response to accidental hydrocarbon spills, providing guidance on notification and spill response requirements. The response strategies and support arrangements included within the VI OPEP are appropriate for the worst scale spill associated with VI Hub activities. Given that the activity is contained within State waters, any spill requiring Level 2/3 activation will require notification to DoT as the relevant Controlling Agency. Santos WA will provide initial control of the incident and then necessary resources and assistant to support DoT once DoT assumes control of the incident as defined in the OPEP.

Exposure controls/personal protection The information in this section contains generic advice and guidance. Information is provided based on typical anticipated uses of the product. Additional measures might be required for bulk handling or other uses that could significantly increase worker exposure or environmental releases. Control parameters Occupational exposure limits

Appropriate engineering : If user operations generate dust, fumes, gas, vapour or mist, use process controls enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. Environmental exposure : Emissions from ventilation or work process equipment should be checked to ensure controls they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.

Individual protection measures Hygiene measures : Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated clothing before reusing. Eye/face protection : Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid exposure to liquid splashes, mists, gases or dusts. If contact is possible, the following protection should be worn, unless the assessment indicates a higher degree of protection: chemical splash goggles and/or face shield. If inhalation hazards exist, a full-face respirator may be required instead. Skin protection Hand protection : Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical products if a risk assessment indicates this is necessary. Considering the parameters specified by the glove manufacturer, check during use that the gloves are still retaining their protective properties. It should be noted that the time to breakthrough for any glove material may be different for different glove manufacturers. In the case of mixtures, consisting of several substances, the protection time of the gloves cannot be accurately estimated. Recommended: > 8 hours (breakthrough time): Rubber gloves. Nitrile gloves.

Additional measures might be required for bulk handling or other uses that could significantly increase worker exposure or environmental releases. Control parameters Occupational exposure limits

Appropriate engineering : If user operations generate dust, fumes, gas, vapour or mist, use process controls enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. Environmental exposure : Emissions from ventilation or work process equipment should be checked to ensure controls they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.

Individual protection measures Hygiene measures : Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated clothing before reusing. Eye/face protection : Safety eyewear complying with an approved standard should be used when a risk assessment indicates this is necessary to avoid exposure to liquid splashes, mists, gases or dusts. If contact is possible, the following protection should be worn, unless the assessment indicates a higher degree of protection: chemical splash goggles and/or face shield. If inhalation hazards exist, a full-face respirator may be required instead. Skin protection Hand protection : Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times when handling chemical products if a risk assessment indicates this is necessary. Considering the parameters specified by the glove manufacturer, check during use that the gloves are still retaining their protective properties. It should be noted that the time to breakthrough for any glove material may be different for different glove manufacturers. In the case of mixtures, consisting of several substances, the protection time of the gloves cannot be accurately estimated. Recommended: > 8 hours (breakthrough time): Nitrile gloves. Neoprene gloves.

Appropriate engineering All activities involving chemicals should be assessed for their risks to health, to controls ensure exposures are adequately controlled. Personal protective equipment should only be considered after other forms of control measures (e.g. engineering controls) have been suitably evaluated. Personal protective equipment should conform to appropriate standards, be suitable for use, be kept in good condition and properly maintained. Your supplier of personal protective equipment should be consulted for advice on selection and appropriate standards. For further information contact your national organisation for standards. Provide exhaust ventilation or other engineering controls to keep the relevant airborne concentrations below their respective occupational exposure limits. The final choice of protective equipment will depend upon a risk assessment. It is important to ensure that all items of personal protective equipment are compatible.

Product name Transaqua HT2 Product code 462602-AU24 Page: 4/10 Version 2.02 Date of issue 27/10/2017 Format Australia Language ENGLISH (Australia) (ENGLISH) Section 8. Exposure controls and personal protection Environmental exposure Emissions from ventilation or work process equipment should be checked to ensure controls they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.

Individual protection measures Hygiene measures Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period. Appropriate techniques should be used to remove potentially contaminated clothing. Wash contaminated clothing before reusing. Ensure that eyewash stations and safety showers are close to the workstation location. Eye/face protection Safety glasses with side shields. Skin protection Hand protection Wear protective gloves if prolonged or repeated contact is likely. Wear chemical resistant gloves. Recommended: Butyl gloves. Neoprene gloves. The correct choice of protective gloves depends upon the chemicals being handled, the conditions of work and use, and the condition of the gloves (even the best chemically resistant glove will break down after repeated chemical exposures). Most gloves provide only a short time of protection before they must be discarded and replaced. Because specific work environments and material handling practices vary, safety procedures should be developed for each intended application. Gloves should therefore be chosen in consultation with the supplier/manufacturer and with a full assessment of the working conditions. Skin protection Use of protective clothing is good industrial practice. Personal protective equipment for the body should be selected based on the task being performed and the risks involved and should be approved by a specialist before handling this product. Cotton or polyester/cotton overalls will only provide protection against light superficial contamination that will not soak through to the skin. Overalls should be laundered on a regular basis. When the risk of skin exposure is high (e.g. when cleaning up spillages or if there is a risk of splashing) then chemical resistant aprons and/or impervious chemical suits and boots will be required. Other skin protection Appropriate footwear and any additional skin protection measures should be selected based on the task being performed and the risks involved and should be approved by a specialist before handling this product. Respiratory protection In case of insufficient ventilation, wear suitable respiratory equipment. The correct choice of respiratory protection depends upon the chemicals being handled, the conditions of work and use, and the condition of the respiratory equipment. Safety procedures should be developed for each intended application. Respiratory protection equipment should therefore be chosen in consultation with the supplier/manufacturer and with a full assessment of the working conditions.
