C. Protect operator during rollover accidents
D. Increase speed
Explanation: ROPS protects the operator in case of overturning.
6. A trench begins to collapse while digging. What is the correct action?
A. Continue digging
B. Speed up excavation
C. Evacuate the area immediately
D. Add more water
Explanation: Collapsing trenches are extremely dangerous and require
immediate evacuation.
7. What is the safest way to enter a cab of heavy equipment?
A. Jump in quickly
B. Use wheels or tracks
C. Use three points of contact
D. Climb from rear only
Explanation: Three points of contact prevent slips and falls.
8. What should you do before refueling equipment?
A. Keep engine running
B. Smoke nearby
, C. Shut off engine completely
D. Increase throttle
Explanation: Prevents fire and explosion hazards.
9. What does “blind spot” refer to in heavy equipment operation?
