What safety precautions must you take when maneuvering on a towing hook?

Correct Answer: Option B — Clear the afterdeck and fantail of personnel.

A towing hook under load stores immense potential energy. If the hook trips or fails, it can cause catastrophic snap-back. Standard safety management requires clearing the afterdeck and fantail of all personnel before maneuvering or operating on a loaded towing hook to prevent severe injury.
