What is a "snap back zone" on a vessel's mooring deck, and what precautions should be taken regarding it?

A. An area where a mooring line or wire under tension could whip back violently with great force if it parts, due to the stored energy in the line; these areas should be identified (often marked with yellow/black hazard paint) and personnel not directly involved in the mooring operation kept clear of them while lines are under load

B. A storage area for spare mooring lines, with no associated hazard

C. A term used only for anchor cable lockers, unrelated to mooring lines on deck

D. A designated area where crew can safely stand while mooring lines are under tension, as it is the furthest point from any line

A. Nothing — a test lift can proceed immediately after repairs

B. The area within the grab's swing radius should be cleared of personnel before the lift

C. Testing should wait until cargo operations begin

D. Only the crane operator needs to be aware the lift is happening

A. Only the weather forecast for the next watch

B. The lunch schedule for the deck team

C. Who must remain clear of the exclusion zone while the lift takes place

D. The cargo manifest for the next port
