Which of the circumstances listed is an exception to the garbage discharge requirements in Annex V to MARPOL 73/78?

Correct Answer: Option A — A person falls overboard, and a plastic ice chest is thrown for flotation.

MARPOL Annex V, Regulation 7, provides exceptions for the discharge of garbage necessary for the purpose of securing the safety of a ship or saving life at sea. Throwing a plastic ice chest overboard for flotation during a man-overboard emergency is a justifiable safety action under these provisions.
