23. HAZARDS AND SAFETY

23.1 Introduction

This chapter describe the potential hazards and risks to people and property that may be associated with the Project in the form of a preliminary risk assessment. An outline of proposed emergency management planning procedures is provided. It should be recognised that the identification and control of hazards and risks to people and property is an integral part of planning for construction and operations and will occur independently of the EIS process.

23.2 Scope

The potential hazards and risks to people and property that may be associated with the Project are identified and possible frequencies are predicted. This includes potential hazards, accidents, spillages and abnormal events that may occur during all stages of the Project; identifying all hazardous substances; potential wildlife hazards; potential natural hazards or events and implications related to climate change.

A preliminary risk assessment was undertaken in accordance with AS/NZSS ISO 31000:2009 Risk Management – Principles and Guidelines, taking into account:

external and on site risks, including transport risks

potential for mosquito breeding sites

construction, operation and decommissioning phases of the project

analysis of the identified hazards, examining individual and collective likelihood and consequences of

each identified hazard involving injuries and fatalities to workers and to the public

quantitative levels of risk.

Details of risk control measures are presented.

The scope of this chapter does not include assessment of environmental risks or economic risks associated with Project delays. Environmental risks and potential economic impacts are addressed in other sections of the EIS.

23.3 Methodology

23.3.1 Overview

Assessment of hazards and risk to people and property from Project activities was undertaken via a preliminary risk assessment in accordance with AS/NZS ISO 31000: 2009. Risk Management – Principles and Guidelines and IEC/ISO 31010 Risk Management: 2009. – Risk Assessment Techniques. The hazard and risk assessment also considers the potential impact on surrounding land use.

The study applies to abnormal hazardous events and conditions, rather than conditions considered to be routine. Hazard identification takes into account compliance with regulatory requirements and therefore deliberately licensed release of pollutants such as air emissions and waste disposal is not included in the assessment.

The assessment involved the following:

Describe values including sensitive receptors.


Page 23-2

Identify any potential hazards to people and property, documented in a hazard identification word

diagram.

Assess probability (likelihood) for hazardous events.

Evaluate the risks associated with each hazard.

Propose mitigation measures.

Consider residual risk mitigation.

23.3.2 Risk Analysis Criteria

ISO 31000 states that risk analysis consists of determining the causes and sources of risk, their consequences and likelihood taking into account the effectiveness and efficiency of controls. Criteria for likelihood and consequence are detailed in Chapter 1.

The likelihood and consequence scales are combined to evaluate the overall level of risk, as outlined in Chapter 1, with the risk analysis matrix presented again in Table 23-1.

23.4 Context

The factors influencing the assessment of risk, and the chapters in which they are described are:

Project activities – Chapter 5

Project location – Chapter 4

sensitive receptors – Chapter 11

land use within and surrounding the Project area – Chapter 11

climate and extremes of climate – Chapter 9

23.5 Environmental Objectives and Performance Outcomes

The environmental objectives and performance outcomes below are based on Schedule 5, Table 2 of the Environmental Protection Regulations 2008 (EP Regulation). The mitigation and management measures presented in this chapter are designed to achieve these environmental objectives and performance outcomes. The environmental management plan (EM Plan) presented in Appendix 13 provides a consolidated description of these mitigation and management measures.

23.5.1 Environmental Objectives

Any waste generated, transported, or received as part of carrying out the activity is managed in a way

that protects all environmental values.

Identify potential hazards to people and property from abnormal hazardous events and conditions.

Determine the residual risk levels (i.e. risks after proposed mitigations measures) and propose new

risk treatment measures if risk are not tolerable.

23.5.2 Environmental Outcomes

No contamination of land or waters from waste management beyond the footprint of waste

management facilities.

If land or groundwater contamination as a result of waste management activities has occurred, an

investigation will be undertaken, with management or remediation as required. This may involve

engaging a suitably qualified person approved by DEHP as a contaminated land specialist where

required, and will fully depend on the nature and extent of contamination.

Following risk treatment measures, there are no residual risks which are determined as high or

extreme and all other risks are as low as reasonably practicable (ALARP).

Prepare a Risk Management Plan and Emergency Management Plan.

23.6 Hazard Identification

The focus of the hazard identification is on abnormal hazardous events and conditions, as specified in Hazardous Industry Planning Advisory Paper No. 3: Risk Assessment, NSW Department of Planning.

Routine emissions and operations are identified in other technical reports prepared for the Project EIS and are addressed via pollution control mechanisms and legislation.

Potential health and safety hazards that may affect site workers in normal on site day-to day activities during the construction and operation of the Project are listed in Table 23-2. These hazards are well


Page 23-4

addressed in workplace health and safety legislation and relevant Australian standards and are not included in the hazard identification process for this EIS.

For each hazardous incident (e.g. fire, spill, leak, collision) the potential initiating events have been defined in order to represent the range of possible incidents as recommended in Hazardous Industry Planning Advisory Paper No. 6: Hazard Analysis, NSW Department of Planning. This enables a more accurate assessment of the conceivable scenarios that could lead to the hazard and therefore appropriate risk treatment measures can be recommended.

Compliance with regulatory requirements is mandatory and therefore the hazard identification processes has assumed compliance with regulatory requirements and relevant Australian Guidelines and Codes applicable to the management and mitigation of hazards and risks at a Queensland mining operation such as the Project. Hazard identification and recommended risk treatment measures have been identified based on the premise that legislation and relevant, widely accepted, Australian Guidelines and Codes are implemented whilst undertaking the activity. These include:

Work Health and Safety Act 2011 and Work Health and Safety Regulation 2011 – aims to secure the

health and safety of workers and workplaces. Workers and others are to be given the highest level of

protection from hazards and risks as is reasonably practicable

AS/NZS ISO 31000:2009 Risk Management Principles and Guidelines - provides a framework for

managing risk and specifies the elements of the risk management process.

AS 1940:2004. The Storage and Handling of Flammable and Combustible Liquids – includes the

requirements and recommendations for the safe storage handling of flammable liquids and

dangerous goods Class 3 (as classified in the United Nations (UN) Recommendations for the Transport

of Dangerous Goods). AS1940:2004 also includes requirements and recommendations for the storage

and handling of combustible liquids and provides minimum acceptable safety requirements for

storage facilities, operating procedures, emergency planning and fire protection. It provides technical

guidance that may assist in the storage and handling of flammable and combustible liquids.

ADG 7. Australian Goods Code - provides technical requirements for the land transport of dangerous

goods across Australia.

Queensland Health (2002). Guidelines to minimise mosquito and biting midge problems in

development areas.

As explosives are not proposed for use in the Project, legislation and codes relevant to explosives have not been considered.

23.7 Site Workers Health and Safety

Table 23-2 details the health and safety hazards that are likely to be present in normal on-site day-to-day activities during construction and operation of the Project. These hazards are well addressed in workplace health and safety legislation and relevant standards and will be complied with at all times during the construction, operation and decommissioning of the Project.

23.8 Public Health and Safety

This section describes the potential health and safety impacts for the public and community associated with the Project. References are provided to other sections of the EIS where these potential health and safety impacts are described in more detail.

23.8.1 Towns and Sensitive Receptors

The nearest population centre to the Project is Mapoon, approximately 15 km south of the most southerly mining lease boundary. The nearest sensitive receptors to the Project live in areas near Mapoon, with the closest receptor approximately 11 km south of the most southerly mining lease boundary.

23.8.2 Land and Water Use

The existing land use within and adjacent to the Project area is described in Chapter 11. There are no permanent residences on or adjacent to the Project area and no regular use of the land. There are no known ongoing uses by the public of fresh surface water or groundwater within or downstream of the Project area.

Water management and potential impacts to water are described in Chapter 6, Chapter 12 and Chapter 13.

Potential flooding of the site is described in Chapter 14. As there is limited use of waters downstream of the Project and the potential for release of contaminants due to flooding is low, it is very unlikely that any flooding will create additional health and safety impacts arising from the Project activities.

Water used by the Project is not predicted to impact on available volumes or quality of water used by people in Mapoon.


Page 23-7

23.8.3 Use of Marine Environment

Use of the estuarine and marine environment in the Skardon River is described in Chapter 22. There is limited use of the Skardon River for recreational and commercial fishing purposes. There are no permanent users of water downstream of the Project, comprising estuarine and marine areas of the Skardon River and Namaleta Creek.

23.8.4 Air Quality

Potential Project and cumulative impacts on air quality are described in Chapter 19. The Project, either in isolation or cumulatively with the nearby Bauxite Hills Project, is not predicted to result in exceedances of air quality objectives in Mapoon. These objectives are designed to protect the health and wellbeing of receptors.

Due to the separation distance between the Project and sensitive receptors, it is very unlikely that any odours generated by the Project will affect the health and safety of the community.

23.8.5 Noise

Potential Project and cumulative impacts on noise levels are described in Chapter 20. The Project, either in isolation or cumulatively with the nearby Bauxite Hills Project, is not predicted to result in exceedances of noise and vibration objectives in Mapoon. These objectives are designed to protect the health and wellbeing of receptors.

23.8.6 Transport

Transport of people, equipment and materials to the Project is described in Chapter 22. As described in Chapter 22, road access to the Project for mining is not practical. The potential hazards and risks to the public associated with road, air and marine transport are described below.

The beach at the Skardon River mouth is currently accessed by tourists in the dry season using bush tracks that intersect the existing haul road (currently no mining occurs and hence no mining vehicles use the haul road). At any one time approximately 10 vehicles may access the beach area. This is the only practical means of accessing the beach to the west of the mining leases. To allow ongoing use of the land parcel (Lot 11 SP204113), including the beach, Gulf will allow access to the mining lease for crossing of the haul road only. There will be no authorised use of the haul road by tourists. The crossing point will be signed and demarcated with access procedures requiring strict compliance.

Management measures have been proposed to reduce transport risks to low or medium.

23.9 Hazardous Substances

The Project will use a number of hazardous substances during construction and operations.

Table 23-3 provides an indicative list of hazardous substances to be used during the Project and the likely quantities stored on site. Material Safety Data Sheets (MSDS) will be available on site where these substances are to be stored or used.

23.10 Natural Hazards

23.10.1 Climate Related Factors

Risks associated with extremes of climate are described in Chapter 9, including temperature extremes, droughts, tropical cyclones, storm surges, erosion prone areas and bushfire risk. The potential for flooding of the Project area for various annual exceedance probability (AEP) rainfall events, is described in Chapter 14.

The potential impacts of climate change on the Project area are temperature increases and either declining or increasing rainfall depending on the climate model. It is possible that the frequency and intensity of storms and cyclones may increase in the area of the Project, although these are expected to be within the natural variation of extremes of climate.


Page 23-9

23.10.2 Wildlife and Disease

There are a number of wildlife species that are potentially dangerous to humans in the Project area, including mammals, dingoes, rats, pigs and various snakes. Increasing potential freshwater breeding sites such as receding flood waters and pooling water can result in larger numbers of mosquitoes, which in turn increases the potential for outbreaks of mosquito-borne diseases (Queensland Health 2011). Notifiable diseases reported in Queensland include barmah forest virus, ross river virus, dengue fever and malaria.

23.11 Preliminary Hazard Identification

Hazard identification, cause, potential consequences and risk treatment measures are described in Table 23-4. The hazard identification process identifies the non-routine hazards associated with the construction, operation and decommissioning (abbreviated as C,O,D) of the mine and associated infrastructure taking into account the Project description, natural hazards and estimated hazardous substances being stored and used on site.

Transport risks and interaction with external projects are also identified. Potential health and safety hazards to the site workers for routine operations are not included as these have been previously identified and can be addressed by compliance with relevant standards and regulations.

23.12 Hazard Analysis and Risk Assessment

This section outlines the risk analysis undertaken in accordance with the method described in Section 23.3 and using the hazard identification table in Section 23.6. The risk analysis takes into account the risk treatment measures included in the hazard identification table on the basis that it is expected that all legal requirements, relevant standards, guidelines and codes of practice will be implemented in the design, construction, operation and decommissioning of the Project. The objective of the risk analysis is to determine whether the residual risks (i.e. risks after proposed mitigations measures) are tolerable and if they are not then to propose new risk treatment measures.

Where the residual risk is determined as high or extreme, these activities are considered for additional risk mitigation.

Tables are prepared for the following hazards and associated risks:

Transportation (Table 23-5)

Bulk storage (Table 23-6)

Construction and Installation (Table 23-7)

Mining Operations (Table 23-8)

Waste Management (Table 23-9)

Infrastructure (Table 23-10)

Decommissioning (Table 23-11)

Interaction with External Factors (Table 23-12)

23.12.1 Risk Evaluation - Transportation

The risk levels to people and property associated with the transportation activities are summarised in Table 23-5. Medium risks were associated with transporting personnel, equipment and materials to and from the site. Although the consequence of transport risks can be severe (e.g. mutiple fatalities), with the appropriate risk treatment measures, the likelihood is rare or unlikely and risk level has been assessed as medium. No high or extreme risks were identified.

23.12.9 Cumulative Risk

Potential interactions with other projects in the region (Metro Mining’s Bauxite Hills Project) were identified in Table 23-12 with associated hazards and risks identified. It is unlikely that there is an increased risk on the hazards identified in Table 23-4 as a result of the Bauxite Hills Project. It is unlikely that the hazards and risks associated with the Project will present additional / increased hazards and risks to other existing or proposed facilities in the vicinity of the Project area.

23.13 Risk Management

23.13.1 Risk Management Plan

A risk management plan will be developed prior to construction and operations. The purpose of the risk management plan will be to provide a framework for the implementation of the risk treatment and reduction measures proposed in this chapter.

It is reiterated that the preliminary risk assessment in this chapter did not consider environmental impacts as they are assessed in other sections of the EIS. Routine operational health and safety risks have been identified and are to be managed in accordance with legislation, standards and codes of practice.

The risk assessment process will be undertaken in detail prior to construction and operation and be maintained as operations and conditions may change. In line with standard industry practice, job safety and environmental analyses should take place prior to the commencement of any activity.

23.13.2 Construction Phase

A Construction Environment, Health and Safety plan will be prepared upon completion of the design stage. The Construction EHS plan will focus on hazards related to both site operations and potential off site impacts. HIPAP7: Construction Safety Guidelines (NSW DoP, 2011) recommends the construction study covers the following:

Familiarisation with past and proposed operations and a review of construction and commissioning

programs

Review of construction safety including identification and analysis of hazards and review / revision of

construction operational controls

Safety assurance including verification that the design intent is maintained throughout the

construction period via safety management systems and pre-commissioning checks


Page 23-23

Change management procedures during construction

23.13.3 Operations Phase

The proponent will structure health, safety and environmental management systems in accordance with OHSAS 18001: 2007. Occupational Health and Safety Management Systems. Requirements and the principles of ISO14001:2004 Environmental Management Systems – Requirements with Guidance for Use.

Risk management principles in line with ISO 31000:2009. Risk Management Principles and Guidelines will be used to identify hazards, assess risks and identify control at all stages throughout the Project. The outcome of the risk management process will be the development of operational control such as health and safety plans, safe work procedures, job safety analyses, inspections, monitoring and audits. Risks will be managed in accordance with the hierarchy of control, with elimination being the first control method to be used.

Hazards and risk will be identified during the Project risk assessment process and documented in a risk register that will be regularly updated. The risk register will be reviewed at any time prior to the introduction of new plant or equipment; change in operations, conditions or plant; after an incident; and at least annually.

Should any risks be identified as high or extreme, additional treatment measures will be assessed and implemented as required to ensure that risks are made as low as reasonably practicable (ALARP).

Safe work procedures will be developed for routine tasks to address the following hazards:

driving

vessel loading and unloading

manual handling

slips and trips

interaction with mobile equipment

working at heights

working with electrical equipment, lightning

working with moving parts

falling objects

fatigue

confined spaces

pinch points

wildlife hazards

disease vectors

dust

noise

sunburn, dehydration, heat stress

welding and cutting

hazardous substances

fire.

Audits will be conducted on a scheduled and regular basis, dependent on the risk of the activity.


Page 23-24

23.13.4 Risk Management - Natural Hazards

23.13.4.1 Bushfire

A bushfire management plan will be developed prior to construction to take into account the following:

Traditional Owner / landowner bushfire management

Maintain safety of people and property by avoiding areas of high or medium bushfire hazard.

Design and siting of buildings.

Firebreaks, setbacks from vegetation and access to firefighting and emergency vehicles.

Adequate road access for firefighting and other emergency vehicles.

Providing an adequate and accessible water supply for fire-fighting purposes.

Ensure public safety and environment are not adversely affected by the detrimental impacts of

bushfire on hazardous materials manufactured or stored in bulk.

These items will be addressed in the detailed design of the site and the Emergency Response Plan.

23.13.4.2 Vector-borne disease

The preliminary hazard and risk assessment identified the potential for the spread of mosquito borne disease as medium. A mosquito management plan will be developed prior to construction and operations.

As specified in the Queensland Health (2002) Guidelines to minimise mosquito and biting midge problems in new development areas, the most appropriate way to control mosquitoes is to prevent them from breeding. It is important to address potential mosquito problems before there is a significant increase in the adult population. Where required, mosquito control programs should integrate a variety of control strategies i.e. surveillance, reducing stagnant water and spraying.

Any incidence of vector-borne disease will be referred to a doctor, with subsequent notification to Queensland Health. Additional treatment measures may be required if the incidence of disease increases beyond background levels in the general community. It is expected that Queensland Health will provide adequate monitoring of incidence of the known vector-borne diseases and will implement appropriate programs to control any outbreaks. It is unlikely that a significant increase in the incidence of vector-borne disease will occur.

23.13.4.3 Wildlife

A procedure will be developed prior to clearing to ensure worker safety. This will take into account prevention of snake bites, as well as first aid and medical treatment. Training and awareness will also be considered.

Suitable site personnel will be trained in first aid. Procedures will be in place to ensure effective transportation to the nearest medical facility, as required.

Further detail will be included in the Emergency Management Plan.

23.13.5 Risk Management - Site Hazards

23.13.5.1 Fire

An on-site fire response capability will be maintained and supported as will be detailed in the Emergency Response Plan.

Proposed control measures include:

Preventive measures relating to control of ignition sources


Page 23-25

Preventive maintenance

Training

Competent and experience workforce

Safety and Health Management System

Emergency response plan and rehearsals

Fire drills will be undertaken on a routine basis. The Project will have a team of employees trained in fire-fighting to the relevant standards. All fire-fighting facilities and equipment will be installed and maintained by a certified supplier.

Further detail on the management of fire will be included in the Emergency Management Plan.

23.13.5.2 Vehicle, Marine Vessel and Aircraft Accidents

A traffic management plan and marine vessel traffic management plan (refer Chapter 22) will be prepared as part of the EHS system. All aircraft will be operated in accordance with regulatory requirements.

Procedures will be in place to ensure all drivers and vessel operators are competent, trained and fit for work to minimise the potential for vehicle or vessel accidents. Standard operating procedures, roster control and fatigue management guidelines will be developed to minimise and reduce the risk of fatigue. These will be in addition to the statutory guidelines set by TMR for Queensland.

The Emergency Management Plan will include how to manage a vehicle, vessel or aircraft accident.

23.14 Outline of Emergency Management Plan

23.14.1 Objective

The objective of the Emergency Management Plan is to detail emergency planning and response procedures for the range of emergency situations identified in the hazard and risk assessment. The plan will be developed prior to construction and operations and evolve during detailed design, construction and operations.

23.14.2 Scope

The Emergency Management Plan will consider the design and operation of the proposed safety / contingency systems to address the following emergency issues, identified in the risk assessment:

floods

sabotage

major health concerns such as flu pandemics

fire prevention / protection

leak detection / minimisation

release of contaminants

emergency shutdown systems and procedures.

Outlines of emergency planning and response strategies to deal with the emergency issues described above are presented. These have and will be determined through ongoing consultation with state and regional emergency service providers and police services. Consultation is described in Chapter 3.

Preliminary plans for emergency medical response and transport and first aid matters are addressed.


Page 23-26

23.14.3 Existing Emergency Services and Medical Resources

Existing emergency services and medical resources are described in Chapter 25. This chapter also describes the proposed use of emergency services and medical resources for the Project, should these be required, recognising the isolated location of the Project and transportation challenges in accessing the Project by road.

23.14.4 Proposed Site Emergency Resources

The details of personnel and resources involved in emergency response are yet to be finalised, the following resourcing requirements are expected to be in place prior to construction:

appropriate number of trained personnel in the following:

first aid and resuscitation

fire fighting

rescue – confined space

rescue – at heights

rescue – water

rescue – explosives

rescue – electricity

rescue – from vehicles

spills management

emergency management team on site at all times

occupational health nurse, occupational health first aiders

water trucks with fire fighting capabilities, as required

The Project Emergency Response Team (ERT) will be trained in occupational first aid and will be the authorised personnel on site to administer first aid.

All mine workers will be trained and assessed in the emergency management plans, as follows:

initially, during site inductions

periodically through drills conducted in accordance with the training plan.

The Emergency Response Team and workers requiring specialised skills will be identified in the training needs analysis process, as part of the Health, Safety and Environmental Management System.

23.14.5 Identified Emergency Situations

An emergency is defined as an abnormal, dangerous or potentially dangerous situation which requires urgent action to control, correct and return to a safe state.

The following examples risks to people and property were identified in the hazard and risk assessment and are deemed as emergency situations that would trigger the emergency management plan:

fire

vehicle collisions and accidents

marine vessel collisions and accidents

aircraft accident


Page 23-27

snake bite

sabotage

disease outbreak

accidental release of fuel, hydrocarbons or other contaminants

23.14.6 Emergency Response

In the event of an emergency requiring the activation of the Emergency Management Plan the Emergency Response Team Leader will:

undertake an initial evaluation

identify a safe approach

contact relevant personnel and agencies (e.g. dial 000)

establish a command post

undertake a risk assessment taking into account the following:

is evacuation required

means by which first aid can be safely administered

preparation of the emergency management team

contact external agencies, if required

plant isolation

fire fighting requirements, spills management

resource allocation

Personnel should not undertake tasks for which they are not trained or competent. Personnel should not undertake tasks which could put them at risk of significant risk of injury or illness.

23.14.7 Emergency Plans

Emergency management planning, including fire management, management of contaminant releases and evacuation protocols are described below.

Emergency response and fire fighting equipment will be identified and implemented based on risk assessment. By necessity the provision of emergency response, fire management and fire protection equipment is identified using risk assessment during the detailed design phase.

Accordingly the process of detailed design for all Project infrastructure, site facilities and hazardous materials stores will include emergency management plans showing incident control points, fire fighting equipment, emergency entry and exit points and other relevant emergency management features.

23.14.8 Fire Management Strategies

The following management strategies will be developed for fire management:

Fire management systems will ensure the retention of fire water on site and/or other fire

suppressants required to combat emergency incidents.

Building safety measures for any construction or permanent accommodation.

Emergency response plans and bushfire mitigation plans.

Provide on-site fire-fighting equipment and train staff to who will be tasked with emergency

management activities to an appropriate level.


Page 23-28

Provision of detailed maps showing the plant outline, potential hazardous material stores, incident

control points, fire-fighting equipment, emergency entry and exit points to site facilities.

Design and management of dangerous goods stores associated with the plant operations, including

fuel storage and emergency response plans.

23.14.9 Fire Management Plan

Prior to each bushfire danger period, the mining manager will ensure that the fire management plan is reviewed and equipment is tested. A Fire Officer will be delegated by the Mine Manager with responsibilities for the following:

compliance with the bushfire management plan

maintenance and inspection of the fire-fighting equipment

establishment and training of the fire-fighting team.

The fire management plan will be updated to include further detail as the Project progresses and include the following detail:

details of fire protection controls in place and maintenance requirements

location of fire equipment

material safety data sheets (MSDS)

location and quantity of hazardous substances

drainage plans and operation of drainage equipment such as bunds and sumps

back up generator for emergency equipment

evacuation plan and evacuation points.

The following resources and equipment will be in place prior to construction:

Fire fighting personnel will be available on site at all times. All site personnel will be trained in basic

fire fighting procedures with hand held extinguishers and selected fire response crews will be trained

in more advanced fire control techniques.

A fire water ring main and hydrant system will be installed at the infrastructure area and

accommodation camp. Fire water will be held in a tank for delivery to the ring main, hydrants and

hose reels by a dedicated electrically driven firewater pump set with diesel back up.

Vehicles with fire-fighting capability and dedicated fire water will be available. These may be used as

water trucks for dust suppression when not required for fire-fighting purposes.

Fire risk management includes firewalls, bunds, standard electrical protection, secondary route of

egress, smoke detection in offices, accommodation and workshops.

All fire fighting facilities and equipment will be installed, serviced, maintained and inspected by

certified personnel.

The fire management plan will describe the response to the potential threat of bushfire and establish clear evacuation routes which demonstrate an acceptable or tolerable risk to people. Any upgrades to the camp accommodation will consider bushfire risk including the radiant heat flux level at any point on the buildings, vehicle access and water supply for fire fighting.

Gulf Alumina will undertake a bushfire site assessment prior to commencing activities to inform the bushfire management plan, with consideration given to the draft model code for bushfire hazard.


Page 23-29

23.14.9.1 Equipment Operation

All plant and equipment will be maintained with efficient exhaust systems. Regular inspections will be undertaken. All vehicles, vessels and mobile equipment will be fitted with appropriate fire extinguishers suitable for the control of flammable liquid and electrical fires. Heavy machinery, vessels and vehicles will be fitted with independent fire suppression systems and fire extinguishers, while light vehicles will be fitted with a minimum of one fire extinguisher.

23.14.9.2 Fixed Plant and Equipment

All buildings will be equipped with suitable fire extinguishers. Their location will be indicated by the appropriate signage. These will be indicated on a site map that will be developed during detailed design.

23.14.9.3 Flammable Liquids

Fuel storage will be designed and operated in accordance with AS1940. Bunds, signage, spill procedures, emergency response planning, training, inspection and a maintenance program will be maintained. Fire fighting equipment will be installed.

23.14.9.4 Clearing Operations

Clearing operations will not be undertaken during periods of high fire danger. When clearing, a filled water truck will be available and be able to access the area of clearing. Site personnel will be trained in the use of site fire-fighting equipment. Only once cleared vegetation has been raked and isolated from surrounding remnant vegetation, will cleared vegetation be burned. Burning will be done during periods of weather that limit the risk of potential causing bushfires. Any permits required for burning will be obtained.

23.14.9.5 Welding Operations

All welding activities, where practicable, will be conducted in the main workshop area. Where welding and cutting are undertaken outside the workshop area, the following procedures will take place:

the area will be cleared of flammable materials

a suitable fire extinguisher will be positioned within reach of the work area.

23.14.9.6 Fire-fighting Equipment and Protection

A suitable fire break will be established and maintained around the perimeter of the infrastructure area and camp. The fire breaks will be a minimum of 6 metres wide and kept free of flammable material.

All fire-fighting extinguishers will comply with AS/NZS 1841.1:2007. Fire-fighting equipment will be compatible with that used by Queensland Rural Fire Service. Routine inspections of fire-fighting equipment will take place at least weekly.

23.14.9.7 Training

All mining workers, including contractors, will receive basic fire control training as part of the induction process and receive regular refresher training.

23.14.9.8 External Resources

The proponent notes the absence of a Rural Fire Brigade in Project area, given its remoteness. Gulf Alumina will give consideration to cooperation with other stakeholders in the area, including nearby resource projects, for resourcing of fire management.


Page 23-30

23.14.10 Vehicle, Vessel or Aircraft Accident or Collision

The response to a vehicle, vessel or aircraft accident will depend on the location, type of transport, occupants and number of occupants involved.

Contractors transporting fuel and other hazardous substances will be expected to have their own emergency response plans, which will be reviewed by Gulf Alumina as part of contractor management requirements in the Health, Safety and Environmental Management System.

Accidents that may occur in public facilities or areas involving transport of workers to and from site will be addressed via notification of emergency services by calling “000” as first priority.

Any accident that may occur on site will be handled by the Emergency Response Team and on-site first aid medical treatment and may involve relevant external agencies, depending on the circumstances.

Job safety risk assessments will take place for all transport tasks. These will address the proposed action on accidents.

23.14.11 Snake Bite

It is unlikely that a snake bite will occur, however if it does eventuate then appropriate first aid treatment will be administered. The patient will be transferred to the nearest suitable medical facility.

23.14.12 Sabotage

A security plan will be developed as the Project progresses.

23.14.13 Major Health Concerns

Major health concerns such as a flu pandemic will be managed in line with Queensland Health advice.

23.14.14 Flood

The plan for response to a flooding event will include immediate actions of providing an alert, monitoring flood levels and monitoring evacuation routes (airstrip and Port). As part of the risk assessment the following items will be addressed:

impact to safety of site personnel

impact to plant and equipment

impact to processes

impacts due to overflows of sewage, fuels and oils

access for evacuation purposes.

23.14.15 Spills, Leaks and Release of Contaminants

To reduce the potential for spills that can have significant environmental impacts the following standards will be established in regards to spill containment:

Bunding containment is installed and maintained on outdoor storage tanks and areas.

Bunding containment is installed on all designated internal liquid storage areas.

Inspections of containment areas are regularly completed and records kept.

Integrity inspections of tanks and field - constructed sumps are completed regularly.

All major storage vessels will be constructed to comply with the following requirements:


Page 23-31

all storage tanks will be constructed in compliance with AS 1940 – The storage and handling of

flammable and combustible liquids

adequate secondary containment equalling at a minimum 110% of the volume of the largest tank in

the containment area

reliable means of level detection

must be constructed using material compatible with and impermeable to the fluid stored

pipelines containing or transporting hazardous materials must be above ground.

tanks and transfer areas should not be located in an area where worst case spills can cause release to

sewer, body of water or soil

A detailed plan for transfer of fuel from supply vessels to storage tanks and from storage tanks to barges will be undertaken. Fuel pipelines will be designed to minimise the risk of accidental release of fuel through safety features such as shut down mechanisms in the event of an emergency. Fuel unloading will be continually monitored during operations. The fuel delivery supply pipelines will be made from welded steel pipes with isolating valves that can be turned off in case of emergency. The coupling system from the steel pipeline to the barges refuelling pipeline will be located above a catch tray (for minor leakages) and in a fully bunded area on the wharf head - to capture any accidental release prior to closing valves in the event of an emergency. All pipelines will comply with Australian Standards.

The existing Port of Skardon River Oil Spill Contingency Plan will be reviewed and updated as required.

A detailed spills response procedure will be developed to address the following principles of spills management:

Communicate that the spill has occurred to the relevant supervisor.

Consider the risk to personal health and the environment. If possible secure the area, identify the

substance and level of response required.

Cease the flow from the source.

Contain the spill to minimise contamination (e.g. temporary bund, cover drains).

Clean up the spill and correctly dispose of the material.

Investigate and reporting how the spill could have been prevented.

A detailed site plan will be available detailing drains, sumps and the location of equipment.

The following equipment will be available on site to assist with liquid spill management:

spill response kits - placed around the site

spill response equipment - emergency response trailer controlled by emergency management team

oil absorbents

sand bags

earth moving equipment can be used to make temporary bunds for containment, if required

23.14.16 Emergency Shutdown Procedures

Emergency shutdown procedures will be developed based on a risk assessment with a cross-section of the workforce.

23.14.17 Evacuation Protocol

Certain emergency situations may require an evacuation of the mine. This will be determined by the Incident Controller. In order to determine the need to evacuate, the following should be considered:


Page 23-32

the risk to people by not evacuating

the risk to people evacuating and entering a dangerous area (e.g. in the case of a bushfire)

how the evacuation can be controlled to avoid injury of personnel.

In such a situation the following procedure will apply:

All personnel will move to their appropriate assembly area and await further directions from the

Incident Controller.

All staff and visitors will be accounted for.

Relevant emergency services will be contacted.

Examples of where evacuation may be appropriate include:

major spill with risk of explosion or fire

cyclone

bushfire

sabotage

23.14.18 Communications and Responsibilities

Contact details will be included in the Emergency Management Plan prior to commencement of construction. Neighbouring properties will be advised, as necessary.

The primary role of the Site Senior Executive (SSE) in the event of an emergency is the coordination of any external agencies that may be required in order to effectively manage the incident.

An Incident Controller will be nominated for mining areas and infrastructure areas. The Incident Controller is primarily responsible for the management of the incident scene.

The most senior ERT member is to act as the Emergency Response Team Leader (ERTL). The ERTL’s primary responsibility is to treat any injured personnel and make the incident scene safe.

Emergency response team members will conduct the rescue and treatment of any injured personnel under the control of the ERTL.

The mine will have an emergency alarm system, built into the site radios, which can be activated by the relevant senior personnel. The emergency alarm will be broadcast across all radio frequencies at the mine.

23.14.19 Audit and Review

To ensure the effectiveness of the Emergency Management Plan, the plan will be periodically tested, audited and reviewed. An investigation will take place after any emergency. Inspections will take place regularly to ensure all emergency equipment is working and has been maintained. Regular training and testing of the emergency response workers will take place.

23.15 Conclusion

Potential hazards and risk to people and property were identified through a preliminary risk assessment for the Project, undertaken in accordance AS/NZSS ISO 31000:2009 Risk Management – Principles and Guidelines.

The focus of the hazard identification and risk assessment was on abnormal hazardous events and conditions. Potential health and safety hazards that may affect site workers in normal on site day to day activities during the construction and operation will be managed through compliance with workplace health and safety legislation.


Page 23-33

Potential public health and safety concerns, natural hazards and hazardous substances proposed for Project use were identified.

Potential hazards, their cause and consequences were identified. Risk treatment and management measures were proposed to mitigate risk. The hazard identification process identified the non-routine hazards associated with Project construction, operation and decommissioning. The risk assessment for each potential hazard considered residual risk (i.e. risk after mitigation) with a view to identifying any residual high or extreme risks requiring additional mitigation. Risk assessments were undertaken for:

transport by air, sea and road of people, equipment, materials and fuel

bulk storage of fuel

construction and installation

mining operations

waste management

infrastructure and accommodation camp

decommissioning

external factors such as interaction with third parties or the public.

No high or extreme residual risks were identified. Never-the-less risk management measures have been proposed and an outline of an emergency management plan prepared. These will be further developed as the Project progresses through each phase of detailed design, construction, operations and decommissioning.

With the implementation of proposed risk management measures, the Project is expected to result in low to medium risks to people and property.
