CPCS Pre-Use Checks

Question 1

What is the primary purpose of a pre-use check on construction plant?

Accepted Answer

To identify defects or hazards before operation begins

Answer

Pre-use checks exist to identify any defects, damage, or hazards before the plant is operated, preventing accidents caused by mechanical failure or unsafe conditions.

Question 2

When should a pre-use check be carried out?

Accepted Answer

Before every work period in which the plant will be used

Answer

A pre-use check must be carried out before every work period — at the start of each shift or whenever the operator takes over the plant — not just periodically.

Question 3

Which of the following would you check as part of a plant pre-use inspection?

Accepted Answer

Fluid levels, tyres or tracks, lights, controls, and safety devices

Answer

A thorough pre-use check covers fluid levels (fuel, oil, coolant, hydraulic), tyres or tracks, lights, mirrors, controls, alarms, safety devices, and any visible structural damage.

Question 4

You carry out a pre-use check and find a hydraulic oil leak. What should you do?

Accepted Answer

Take the plant out of service and report it before operating

Answer

A hydraulic oil leak can cause sudden loss of control and is a serious safety defect. The plant must be taken out of service immediately and the defect reported for repair.

Question 5

What should an operator do if a pre-use check reveals the travel alarm is not working?

Accepted Answer

Take the plant out of service and report the defect

Answer

A travel alarm warns nearby workers of plant movement. Its absence is a significant safety hazard requiring the plant to be taken out of service until the alarm is repaired.
