CPCS Pre-Use Checks 1 — Questions and Answers
Question 1: What is the primary purpose of a pre-use check on construction plant?
- To identify defects or hazards before operation begins (Correct answer)
- To record the plant's fuel consumption
- To log the operator's working hours
- To check the plant's insurance documents
Correct answer: To identify defects or hazards before operation begins
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?
- Before every work period in which the plant will be used (Correct answer)
- Only on Monday mornings
- Only after the plant has been serviced
- Once a week regardless of use frequency
Correct answer: Before every work period in which the plant will be used
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?
- Fluid levels, tyres or tracks, lights, controls, and safety devices (Correct answer)
- Only the fuel level and engine oil
- The plant's registration documents and insurance
- The site manager's signature on the work order
Correct answer: Fluid levels, tyres or tracks, lights, controls, and safety devices
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?
- Take the plant out of service and report it before operating (Correct answer)
- Add more oil and continue working
- Cover the leak and monitor it during the shift
- Report it at the end of the day
Correct answer: Take the plant out of service and report it before operating
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?
- Take the plant out of service and report the defect (Correct answer)
- Rely on a banksman instead and continue working
- Operate slowly and sound the horn when reversing
- Continue working as the alarm is not always needed
Correct answer: Take the plant out of service and report the defect
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.
Question 6: Who is responsible for completing the pre-use check?
- The operator who will be using the plant (Correct answer)
- The site manager only
- The plant hire company
- A dedicated safety inspector only
Correct answer: The operator who will be using the plant
The operator who will be using the plant is responsible for completing the pre-use check. They are in the best position to notice changes from the previous shift and are accountable for operating the plant safely.
