List of questions in above test (quick view). Click question box to reveal correct answer.
1. What action should the machine operator undertake when working with non-hoist rope lifting equipment (e.g. excavator, forklift etc) immediately before going to attach or disconnect a load? Give ONE Answer
A Check the fuel
B Conduct a full safety inspection of the equipment
C Confirm that the machine's controls are isolated
D Signal with lights to other operators that their task is about to commence
Correct Answer: C Confirm that the machine's controls are isolated
Explanation: When working with non-hoist rope lifting equipment (e.g. excavator, forklift etc) immediately before going to attach or disconnect a load, a machine operator must always confirm that the machine's controls are isolated. This is to that no unplanned movement of any part of the machine can occur
