Documentation Mining Industry Specific Compliance Documentation Each mining sector / resource will have legislative guidelines that form the framework of legislative direction within the mining industry. Each set of Legislation has a purpose to: −
Protect the safety and health of persons at mines and persons who may be affected by mining operations; and
−
Require that the risk of injury or illness to any person resulting from mining operations be at an acceptable level.
The definition of a hazard is “sources of potential harm or a situation with a potential to cause loss”. Each mine operates in a different way under different conditions to maximise productivity and reduce costs. The hazards will be to that mine. These hazards will be dealt with by Risk Assessments, Standard Operating Procedures, Management Plans, and other planning procedures developed for that mine under its Safety Health Management System. Understanding the site SHMS procedures is vital for the mine worker at all levels to effectively monitor the mining operations to ensure work is conducted in a safe and efficient manner.
Recognised Standards Recognised standards provide ways of achieving an acceptable level of risk for people working in mines. Operators can manage the risk differently but must be able to show that the method used is at least equivalent to the method in the recognised standard. This is normally set at a State or Territory level; however Federal Recognised Standards may apply.
Standards Australia Standards Australia is the nation's peak non-government, not-for-profit Standards organisation whose main responsibility is the development and adoption of standards in Australia. Technical committees are brought together, and through a process of consensus, these committees develop standards for Australia’s net benefit. Standards set out the specifications, procedures, and guidelines. They are designed to ensure products, services and systems are safe, reliable, and consistent. They are based on industrial, scientific and consumer experience and are regularly reviewed to ensure they keep pace with new technologies.
The Mine Safety Health Management System Under a mine’s safety and health management system, all persons must be given notification of matters that could affect health and safety immediately if they arise. An example of this could be the development of a crack in a high wall or low wall. Not all hazards exist at every mine, they are not the same, and because of this, a mine is only required to have Principal Hazard Management Plans place for hazards that exist at the mine and Standard Operating Procedures for the tasks if they intend to have undertaken at the mine. The development of Standard Operating Procedures (SOPs) must be done in consultation with the workers who are involved in carrying out that task (a cross-section of the workforce). Each worker at the mine is required to have access to and understand how to access approved Principal Hazard Management Plans, Standard Operating Procedures, and other documents that support the implementation of these procedures like Trigger Action Response Plans, Permits and Duty Cards as an example. Locations may include a central computer system / intranet system and or copies printed in and stored in the training rooms or Supervisor’s office. It is important to ensure the Principal Hazard Management Plans, Standard Operating Procedures or Work Instructions you are using is the active / controlled approved version.
Obligations of Mine Workers All personnel should be aware of how to obtain the information relating to their work and take time to read the requirements of their job requirements to ensure compliance. If the information is unclear, then they should consult their Supervisor for interpretation and clarification. The implementation of procedures underpinning the mine SHMS shall be monitored by Managers, Superintendents and Supervisors to ensure they are being used in the workplace. Implementation, auditing and checking the Mine Worker’s understanding of the Safety and Health Management System procedures is an ongoing task if Mine Workers are found to be non-compliant refresher training will be required and depending on the severity of the non-compliance disciplinary action may be taken.

Pre-start Inspections Prior to performing a walk-around and pre-start inspection of the excavator, visually check the immediate area for trip hazards and moving parts, the excavator is shut down in accordance with site procedures and any non-authorised personnel and/or equipment are clear of the immediate area. Always look around, look down and look up prior to approaching the machine.
Walk-around Inspection The purpose of a walk-around inspection is to: -
Check the excavator for any obvious damage.
-
Ensure that no personnel are in, under, behind or around the excavator before boarding.
-
Check that the terrain you intend operating in, or moving into, is clear.
A walk-around inspection takes place outside the footprint of the excavator, and must be conducted: -
Before boarding and prior to operating the excavator after being absent from the cab for any length of time (e.g. smoko or crib).
-
After refuelling.
-
After repairs, maintenance or inspections have been completed.
-
At any time to ensure the safe departure of persons or vehicles who have been near the excavator.
Conducting the Walk-around Inspection To promote a systematic approach for pre-start checks, it is recommended that you begin the inspection at the same point each time. A personal risk assessment must be completed, and a personal danger tag fitted to the isolation point of the excavator prior to conducting a walk-around inspection. A minimum of two (2) metres clearance from the sides and rear of the excavator must be maintained. A full pre-start inspection including the fire system should be performed at each shift change or after repair or service work has been performed to check for evidence of damage or component wear. When conducting the walk-around inspection, checks include, but are not limited to: -
The isolation points for tags and read any information they contain.
-
Track tension and condition.
-
For fluid leaks, e.g. oil, fuel, water / coolant, hydraulic.
-
For any obvious structural damage, including handrails and guards, and missing parts / nuts / bolts.
-

Excess wear or other abnormalities.
