Health, Safety and Environmental Regulations and Responsibilities
This domain tests whether you understand the legal framework and whose neck is on the line. Key concepts: the employer's duty to provide a safe system of work, information, training and supervision; the operator's personal duty to take reasonable care of themselves and others and to co-operate with the employer; the requirement to report defects and refuse to operate unsafe equipment; environmental duties covering spill prevention, refuelling, waste segregation and noise/dust control.
Know the difference between a hazard (something with potential to cause harm) and a risk (the likelihood and severity of that harm). Questions love to swap these. Also distinguish a risk assessment (identifies hazards and controls) from a method statement (describes how the work will be done) and a permit to work (formal authorisation for higher-risk tasks).
Traps to watch:
- Assuming the supervisor is solely responsible for safety - every worker has duties.
- Confusing 'reasonably practicable' with 'do everything possible'.
- Forgetting that near-misses must be reported, not just injuries.
- Thinking PPE protects against all hazards - it is the last line of defence in the hierarchy of control.
Hierarchy of control (rule of thumb): Eliminate → Substitute → Engineering controls → Administrative controls → PPE. If a question asks the best control, the answer is almost always the one highest up this list, not the PPE option.
Worked example: A hydraulic hose bursts and oil spills on the yard. Immediate actions: stop work, isolate, contain the spill with a spill kit, prevent it reaching drains, report it, and arrange disposal as hazardous waste. Oil down a drain is an environmental incident, not just a housekeeping issue.
