Safety and health at Leighton Contractors
The Mining Safety Essentials at work
Thinking and working safely is part of our culture. Our first and most important value is safety and health above all else, and through its guiding behaviours, we make it clear to our leaders and team members that:
Frontline leadership
w e look after our workmates as if they are family we take action when we see a safety risk. The goal of our framework is Zero Harm—and our focus is on eliminating the potential for fatalities and permanent disabilities, while systematically reducing all other injuries. The Mining Safety Essentials Leighton Contractors’ Mining Safety Essentials are the minimum, nonnegotiable requirements on how we manage critical risk in our business. They are the areas we have identified from our 30 years’ experience in contract mining that give rise to severe consequences if they are not clearly understood and applied. They reinforce our systems and processes—they do not replace them. Nothing replaces the need for everyone to proactively manage risk every day, in every task they undertake. It’s about realising a step change in our safety performance. The Essential Behaviours Every Mining Safety Essential has defined behavioural expectations for those directly involved in doing the work (Working Behaviours), and those who plan, coordinate, schedule or manage the critical risk activity. You must be familiar with and adhere to the behaviours relevant to your role at all times. For more information, please refer to your Essential Behaviours pocket guide, as well as consult regularly with your supervisor and SHE representatives. 04 | LEIGHTON CONTRACTORS
It is important to remember that we all need to show commitment and leadership when it comes to safety, and that we will all need to be the ambassadors and champions of the Mining Safety Essentials if we are to succeed. In addition, critical risk activities require a higher level of supervision, and frontline leaders overseeing critical risk activities must ensure that, prior to any work commencing, their people and teams: have been consulted have been provided with an opportunity to comment on the proposed system of work have received the work instructions and understand them are trained and authorised to undertake the work fully understand the risks and controls. Accountability and compliance The Mining Safety Essentials requirements are non-negotiable, and all Leighton Contractors’ employees and subcontractors need to adhere to them at all times. You are encouraged to discuss any issues of concern with your supervisor, and also bring forward your innovations and ideas, so that we can continuously improve. You also have an obligation to report any breaches to your supervisor. It is expected that while carrying out critical risk activities, you will comply with the Mining Safety Essentials and the relevant external and internal obligations, including Statutory Acts and Regulations, Australian Standards, Codes and Practices, our company business standards, and client requirements.

INTRODUCTION
Where the expectations prescribed in these documents are exceeded by the Mining Safety Essentials, the Mining Safety Essentials requirements will take precedence. Within the Mining Division, processes exist to assist with the implementation of the Mining Safety Essentials and the effective management of critical risk. These processes need to be complied with. They include, but are not limited to, the: exceptions process permit to work process change management processes (e.g. modify fixed or mobile plant processes). Identification of hazards and assessment of risk As defined in the Mining Safety Essentials, activities containing a critical risk will: b e supported by a risk assessment conducted by competent person(s) be captured in Active Risk Manager (ARM) with a nominated Risk Owner have a work instruction that describes the controls identified by the risk assessment to manage the critical risk(s) have a monitoring and review schedule. Prior to commencing any critical risk activity you must complete a risk assessment. Innovation: using engineering to help eliminate risk Where Leighton Contractors is responsible or has the capacity to influence, all opportunities to design out critical risks should be fully explored. This includes, but is not limited to: d esigning out the need to access/ work at heights, or in confined spaces designing adequate walkways and work platforms ensuring that lockable isolation mechanisms and fail safe systems installed on plant and electrical installations are fitted
p rogramming project schedules, sequencing and techniques to utilise in-situ permanent facilities, rather than relying on temporary measures (e.g. temporary access scaffolds) managing vehicle interactions, as part of intersection and pit design. Training and authorisation Competencies required for persons involved in a critical risk activity must be documented. These include national competency units. All persons undertaking critical risk activities, as defined in the Mining Safety Essentials, are required to undergo a verification process to confirm they have the required competencies to work safely before being authorised. Authorisation is required from the project manager, project manager’s delegate, or a person detailed in the Safety and Health Management System.
Exceptions (with executive approval only) In exceptional circumstances, where compliance to a Mining Safety Essential requirement is not possible, a written Essential Exception is required from the general manager who has line accountability for the project. Technical support If you require additional technical support, please contact the SHE advisors at your project, or email one of the nominated technical support contacts listed on Our Way. Note: The term ‘process’ is used throughout this document in reference to any formal process or procedure that exists within Leighton Contractors, or its project management system, including (but not limited to) Our Way processes, standard operating procedures (SOPs), or Work Instructions and other procedures.
Training that is outsourced should only be conducted by approved third party providers.
Hierarchy of control When assessing the risks to determine controls, your first consideration should always be to eliminate the risks whenever possible.
If this is not possible:
Develop and implement Working Above the Line controls.
If this is not possible: (and as a minimum)
Implement the requirements of the Mining Safety Essentials.
If this is not possible:
In exceptional circumstances, where compliance to a Mining Safety Essential requirement is not possible, a written Essential Exception is required from the General Manager who has line accountability for the project.

Safety and health at Leighton Contractors
The Mining Safety Essentials at work
Thinking and working safely is part of our culture. Our first and most important value is safety and health above all else, and through its guiding behaviours, we make it clear to our leaders and team members that:
Frontline leadership
w e look after our workmates as if they are family we take action when we see a safety risk. The goal of our framework is Zero Harm—and our focus is on eliminating the potential for fatalities and permanent disabilities, while systematically reducing all other injuries. The Mining Safety Essentials Leighton Contractors’ Mining Safety Essentials are the minimum, nonnegotiable requirements on how we manage critical risk in our business. They are the areas we have identified from our 30 years’ experience in contract mining that give rise to severe consequences if they are not clearly understood and applied. They reinforce our systems and processes—they do not replace them. Nothing replaces the need for everyone to proactively manage risk every day, in every task they undertake. It’s about realising a step change in our safety performance. The Essential Behaviours Every Mining Safety Essential has defined behavioural expectations for those directly involved in doing the work (Working Behaviours), and those who plan, coordinate, schedule or manage the critical risk activity. You must be familiar with and adhere to the behaviours relevant to your role at all times. For more information, please refer to your Essential Behaviours pocket guide, as well as consult regularly with your supervisor and SHE representatives. 04 | LEIGHTON CONTRACTORS
It is important to remember that we all need to show commitment and leadership when it comes to safety, and that we will all need to be the ambassadors and champions of the Mining Safety Essentials if we are to succeed. In addition, critical risk activities require a higher level of supervision, and frontline leaders overseeing critical risk activities must ensure that, prior to any work commencing, their people and teams: have been consulted have been provided with an opportunity to comment on the proposed system of work have received the work instructions and understand them are trained and authorised to undertake the work fully understand the risks and controls. Accountability and compliance The Mining Safety Essentials requirements are non-negotiable, and all Leighton Contractors’ employees and subcontractors need to adhere to them at all times. You are encouraged to discuss any issues of concern with your supervisor, and also bring forward your innovations and ideas, so that we can continuously improve. You also have an obligation to report any breaches to your supervisor. It is expected that while carrying out critical risk activities, you will comply with the Mining Safety Essentials and the relevant external and internal obligations, including Statutory Acts and Regulations, Australian Standards, Codes and Practices, our company business standards, and client requirements.
INTRO
INTRODUCTION
Where the expectations prescribed in these documents are exceeded by the Mining Safety Essentials, the Mining Safety Essentials requirements will take precedence. Within the Mining Division, processes exist to assist with the implementation of the Mining Safety Essentials and the effective management of critical risk. These processes need to be complied with. They include, but are not limited to, the: exceptions process permit to work process change management processes (e.g. modify fixed or mobile plant processes). Identification of hazards and assessment of risk As defined in the Mining Safety Essentials, activities containing a critical risk will: b e supported by a risk assessment conducted by competent person(s) be captured in Active Risk Manager (ARM) with a nominated Risk Owner have a work instruction that describes the controls identified by the risk assessment to manage the critical risk(s) have a monitoring and review schedule. Prior to commencing any critical risk activity you must complete a risk assessment. Innovation: using engineering to help eliminate risk Where Leighton Contractors is responsible or has the capacity to influence, all opportunities to design out critical risks should be fully explored. This includes, but is not limited to: d esigning out the need to access/ work at heights, or in confined spaces designing adequate walkways and work platforms ensuring that lockable isolation mechanisms and fail safe systems installed on plant and electrical installations are fitted
p rogramming project schedules, sequencing and techniques to utilise in-situ permanent facilities, rather than relying on temporary measures (e.g. temporary access scaffolds) managing vehicle interactions, as part of intersection and pit design. Training and authorisation Competencies required for persons involved in a critical risk activity must be documented. These include national competency units. All persons undertaking critical risk activities, as defined in the Mining Safety Essentials, are required to undergo a verification process to confirm they have the required competencies to work safely before being authorised. Authorisation is required from the project manager, project manager’s delegate, or a person detailed in the Safety and Health Management System.
Exceptions (with executive approval only) In exceptional circumstances, where compliance to a Mining Safety Essential requirement is not possible, a written Essential Exception is required from the general manager who has line accountability for the project. Technical support If you require additional technical support, please contact the SHE advisors at your project, or email one of the nominated technical support contacts listed on Our Way. Note: The term ‘process’ is used throughout this document in reference to any formal process or procedure that exists within Leighton Contractors, or its project management system, including (but not limited to) Our Way processes, standard operating procedures (SOPs), or Work Instructions and other procedures.
Training that is outsourced should only be conducted by approved third party providers.
Hierarchy of control When assessing the risks to determine controls, your first consideration should always be to eliminate the risks whenever possible.
If this is not possible:
Develop and implement Working Above the Line controls.
If this is not possible: (and as a minimum)
Implement the requirements of the Mining Safety Essentials.
If this is not possible:
In exceptional circumstances, where compliance to a Mining Safety Essential requirement is not possible, a written Essential Exception is required from the General Manager who has line accountability for the project.

11. Working at heights
there is the potential to fall from one level to another an object has the potential to fall and cause injury. It describes minimum requirements and Above the Line principles to prevent: persons falling from heights persons being struck by falling objects. This Safety Essential does not apply to rope rescue performed by competent emergency response team members.
11.3 A working at heights process shall be developed based on a risk assessment identifying the working at heights activities conducted on site. 11.4 A Work at Heights permit is required where there is potential to fall two metres or more from or through a surface, and: there is no compliant fixed edge protection; and/or edge protection must be removed as part of the activity; and/or a fall restraint system is used as the primary control.
Minimum Requirements
11.5 The Working at Heights permit shall include a rescue plan.
Note: Where the minimum requirements cannot be implemented, an Essential Exception Form shall be signed and approved by the general manager.
11.6 There shall be an inspection and maintenance process to ensure the structural integrity of:
11.1 Work shall not be conducted above a height of two metres and/or within two metres of an unprotected edge, opening or fragile surface where there is potential to fall more than two metres without one or more of the following controls in place: temporary hand rails hard barriers working platforms and access equipment (e.g. elevated work platforms, baskets, mancages and scaffolding); or, as a last resort personal fall protection equipment, provided the setup prevents a free fall (fall restraint system). Personal fall arrest systems (e.g. that permit the user to free fall) cannot be used as a primary control.
working at heights equipment anchor points access equipment permanent access ways hand rails on and for mobile and fixed plant.
11.7 All working at heights equipment shall be: r egistered, inspected and tagged quarterly by a certified body stored and maintained in accordance with the manufacturer’s requirements inspected before and after use.
11.8 Personnel working in elevated work platforms or suspended work baskets (excluding scissor lifts) shall wear fall arrest equipment attached to certified anchor points.
Above the Line principles Above the Line controls are the most effective methods of control and should always be exhausted before implementing Below the Line controls. Some examples of Above the Line controls associated with working at heights are:
11.9 During working at heights activities, elevated work platforms shall be protected from collision with barricading and not be operated outside their design parameters.
Modify tasks to bring the job to the ground Eliminate Get rid of
11.10 Exclusion zones shall be established using signage and barricades to identify areas where objects could fall and restrict access. If a total exclusion zone cannot be achieved then overhead protective structures shall be implemented.
