Question

practice exam question 20 of 60 question 20 if an operator falls overboard, what can keep him or her from being the victim of a propeller strike? a a safety harness b a loud whistle c a bulletproof pfd d an engine cut-off switch lanyard

Explanation:

An engine cut - off switch lanyard is designed to stop the engine immediately when the operator falls overboard. This prevents the propeller from continuing to spin, thus avoiding a propeller strike. A safety harness (A) is for preventing falls overboard rather than preventing propeller strikes after a fall. A loud whistle (B) is for signaling, not for stopping the engine/propeller. A bulletproof PFD (C) is not relevant as PFDs are for flotation, and "bulletproof" is not a characteristic related to preventing propeller strikes.

Answer:

D. an engine cut - off switch lanyard
