Q1A banksman is directing a crane lift but loses sight of the load due to an obstruction. The site manager instructs the banksman via radio to "keep lowering" to save time. How must the banksman respond?
✓ Correct answer: D. Halt the lift immediately
Operations must stop immediately if visual contact is lost. Safety overrides schedule pressure or remote instructions until safe vision is restored.
Q2An operator notices a deep crack in the casing of a 110V drill during a pre-use check. The drill has a PAT test sticker valid for another six months. What is the correct course of action?
✓ Correct answer: C. Quarantine the drill immediately
A valid PAT sticker does not negate visible defects. Any equipment with physical damage affecting safety must be removed from service immediately.
Q3A worker needs to install a security camera at a height of 5 meters on soft, uneven ground. Under PUWER, which piece of equipment is most suitable for this task?
✓ Correct answer: B. Use an all-terrain MEWP platform
PUWER requires equipment suitable for the conditions. An all-terrain MEWP provides the necessary stability for working on soft, uneven ground.
Q4Following a thorough examination under LOLER, a lifting accessory is reported to have a defect involving an 'immediate risk to persons'. What must happen to this equipment?
✓ Correct answer: A. Withdraw from use immediately
LOLER mandates that any defect posing an immediate danger requires the equipment to be taken out of service immediately.
Q5What is the primary hazard associated with driving a forward-tipping dumper across a steep gradient (slope)?
✓ Correct answer: D. The vehicle overturning sideways
Dumpers have a high center of gravity. Driving across a slope creates a high risk of lateral instability and overturning.
Q6Which sequence correctly represents the safe isolation procedure before maintaining dangerous machinery?
✓ Correct answer: C. Switch off, isolate, lock, test
Safe isolation ensures equipment is dead before work starts. The correct sequence is: switch off, isolate, lock off, then test.
Q7If a plant operator discovers a safety-critical defect during a pre-use check, who must be informed immediately?
✓ Correct answer: B. The site supervisor
Report defects immediately to the site supervisor. The supervisor can remove the equipment from service to prevent unsafe use.
Q8A carpenter finds that the blade guard on a circular bench saw is broken. What is the only safe action to take?
✓ Correct answer: A. Do not use the machine
Never operate machinery with broken guards. Remove the saw from service immediately until it is repaired by a competent person.
Q9A site entrance has heavy plant traffic crossing a pedestrian walkway. Which control measure is the most effective for segregating people from vehicles?
✓ Correct answer: D. Fixed barriers with gated crossings
Physical barriers provide positive segregation, preventing accidental contact. This is more effective than relying on pedestrian behavior or PPE.
Q10A lithium-ion battery for a power tool feels extremely hot to the touch and is emitting a strange chemical smell. What does this indicate?
✓ Correct answer: C. Imminent thermal runaway failure
Heat and chemical smells indicate thermal runaway. The battery cells are failing and may catch fire or explode imminently.
