CITB Plant and Equipment 2 — Questions and Answers
Question 1: What is the purpose of a thorough examination of lifting equipment?
- To verify the equipment is safe, identifying defects before they cause failure (Correct answer)
- To clean the equipment
- To repaint the equipment
- To measure the equipment dimensions
Correct answer: To verify the equipment is safe, identifying defects before they cause failure
Thorough examinations by competent persons identify wear, damage, and defects that could lead to equipment failure and accidents.
Question 2: What is the rated capacity of a crane?
- The maximum load the crane can safely lift at a given radius and configuration (Correct answer)
- The weight of the crane itself
- The speed at which the crane can rotate
- The height the crane can reach
Correct answer: The maximum load the crane can safely lift at a given radius and configuration
Rated capacity is the maximum load a crane can safely lift, which varies with the radius (distance from the center) and the crane configuration.
Question 3: What safety devices should be fitted to mobile plant?
- Reversing alarms, mirrors, cameras, flashing beacons, and seatbelts (Correct answer)
- Only a horn
- No safety devices are required
- Only mirrors
Correct answer: Reversing alarms, mirrors, cameras, flashing beacons, and seatbelts
Mobile plant should have multiple safety devices including reversing alarms, mirrors, cameras, rotating beacons, and seatbelts to protect operators and nearby workers.
Question 4: What is the purpose of a daily defect report for construction plant?
- To record any defects or issues found during pre-use checks so they can be addressed (Correct answer)
- To track fuel consumption
- To record working hours for payroll
- To maintain a maintenance log for warranty purposes
Correct answer: To record any defects or issues found during pre-use checks so they can be addressed
Daily defect reports document any issues found during inspections, ensuring they are communicated to management and addressed before the equipment is used.
Question 5: What are the risks of refueling construction plant?
- Fire and explosion from fuel vapors, environmental contamination from spills (Correct answer)
- No risks with modern equipment
- Only the risk of overfilling
- Only a risk in cold weather
Correct answer: Fire and explosion from fuel vapors, environmental contamination from spills
Refueling poses fire risks from flammable vapors and environmental risks from fuel spills. Proper procedures include no smoking, engine shutdown, and spill containment.
Question 6: What is the importance of ground conditions for plant operations?
- Soft, wet, or unstable ground can cause machines to sink, slide, or overturn (Correct answer)
- Ground conditions are irrelevant for tracked machines
- Only cranes are affected by ground conditions
- Ground conditions only matter for foundations
Correct answer: Soft, wet, or unstable ground can cause machines to sink, slide, or overturn
Ground bearing capacity affects the stability of all plant. Soft or waterlogged ground can cause machines to sink, tilt, or overturn, especially heavy cranes.
