Work at height, scaffolding and fall protection
This domain tests work at height, which is any place where a fall could cause injury. The exam expects the avoid, prevent, mitigate sequence and practical scaffold checks.
Core rules
- Avoid work at height where possible; prevent falls by using guarded platforms, edge protection and safe access; mitigate remaining risk with fall arrest and rescue arrangements.
- Scaffolds must be erected, altered and dismantled by competent scaffolders. Provide guardrails, toe boards, safe access and a stable base. Check the inspection tag and do not use an incomplete or expired scaffold.
- Never climb scaffold standards. Do not overload platforms or remove ties and boards.
- Fall arrest harnesses need a suitable anchor point, correct lanyard length and a rescue plan. A harness without rescue arrangements can leave a suspended worker at risk.
Worked example
A worker is asked to paint a wall from a 4 m scaffold. The top platform has no guardrail and the access ladder is loose. The correct response is to stop work, barricade the area, have the scaffold completed and inspected, and provide safe access. The reasoning is that the fall hazard is not controlled; painting is not urgent enough to justify using an incomplete scaffold.
Traps
Do not use a ladder as a work platform for prolonged work. Do not clip a lanyard to a weak point. Do not accept a scaffold because it 'looks complete'. Do not forget rescue after fall arrest.
