CPCS Pre-Use Checks 3 — Questions and Answers
Question 1: What should an operator check regarding the operator's cab during a pre-use inspection?
- Seat condition, seat belt, mirrors, controls accessibility, and cleanliness (Correct answer)
- Only that the seat is present
- That the cab is locked when not in use
- The cab's paint condition and cleanliness only
Correct answer: Seat condition, seat belt, mirrors, controls accessibility, and cleanliness
The cab check includes seat condition and adjustment, seat belt integrity and function, mirror condition and adjustment, accessibility and function of all controls, and absence of debris that could obstruct pedals or controls.
Question 2: During a pre-use check, you find the fire extinguisher is missing from the cab. What should you do?
- Report it and ensure it is replaced before operating the plant (Correct answer)
- Operate the plant — fire extinguishers are optional on plant
- Use a bucket of sand as a substitute
- Note it in the log and replace it next week
Correct answer: Report it and ensure it is replaced before operating the plant
A fire extinguisher is required safety equipment on construction plant. Its absence means the plant lacks essential emergency response equipment and it must be replaced before operation.
Question 3: What does checking 'ground conditions' before operating plant involve?
- Assessing the ground for stability, soft spots, slopes, and underground services (Correct answer)
- Only checking for puddles on the surface
- Verifying the ground has been signed off by the architect
- Checking the soil type for environmental records only
Correct answer: Assessing the ground for stability, soft spots, slopes, and underground services
Ground condition checks assess stability for the plant's weight, identify soft ground or voids that could cause sinkage or tip-over, check slopes that affect stability, and identify underground services that could be struck.
Question 4: Why is it important to check that all lights and beacons are working during a pre-use check?
- They warn other workers and traffic of the plant's presence and movement (Correct answer)
- Lights are only required for night operations
- Beacons are decorative and not a safety item
- Lights are checked for insurance purposes only
Correct answer: They warn other workers and traffic of the plant's presence and movement
Working lights and beacons are essential for visibility and warning others of the plant's presence, particularly when reversing or operating in low-visibility conditions. They are a key safety requirement.
Question 5: A pre-use check reveals the machine's horn is not functioning. What should the operator do?
- Take the plant out of service and report the defect (Correct answer)
- Continue working and use hand signals instead
- Shout warnings to nearby workers
- Operate at reduced speed without the horn
Correct answer: Take the plant out of service and report the defect
The horn is a critical warning device for alerting nearby workers. A non-functioning horn is a safety defect requiring the plant to be taken out of service until repaired.
Question 6: During a pre-use check, what should be inspected on the plant's undercarriage or running gear?
- Track condition, track tension, rollers, sprockets, and any signs of damage or leaks (Correct answer)
- Only the fuel tank underneath
- The manufacturer's serial number plate
- The undercarriage paint condition only
Correct answer: Track condition, track tension, rollers, sprockets, and any signs of damage or leaks
The undercarriage inspection covers track or tyre condition, correct tension, roller and sprocket condition, and any signs of damage, wear, or fluid leaks that could affect safe operation.
