You must evacuate crewmembers from a space filling with smoke. The primary means of escape is blocked by the fire. What fire control plan symbol, in illustration D039SA below, designates the secondary means of escape?

Correct Answer: Option A — 62

IMO standardized fire control symbols utilize specific graphical designations aligned with IMO Resolution A.954(23) and SOLAS requirements. Symbol number 62 specifically denotes a secondary means of escape or emergency exit route, vital for crew evacuation when primary passageways are compromised by smoke or flames.
