415. Coast Guard Regulations (46 CFR Part 113) require refrigerated spaces that can be locked from the outside and that cannot be opened from the inside to have an audible alarm. Where is the audible alarm required to be?

Coast Guard regulations (46 CFR Part 113) mandate that alarms for refrigerated spaces with exterior locks and interior inaccessibility sound in a manned location to ensure prompt assistance for potentially trapped personnel. This requirement prioritizes audibility in areas routinely attended by crew, distinguishing it from spaces like galleys, wheelhouses, or individual berthing quarters that lack guaranteed continuous attendance.
