What is the alarm signal for dismissal from a fire emergency or fire drill onboard a merchant ship?

Correct Answer: Option C — General alarm sounded 3 times supplemented by 3 short blasts of the whistle.

Dismissal from fire stations or drills is signaled by sounding the general alarm three times, supplemented by three short blasts of the whistle. This protocol, established under 46 CFR 199.110, ensures that all personnel clearly understand that the fire emergency or drill has been officially terminated.
