What is the traditional signal for fire aboard ship?

• A. More than 6 short blasts and 1 long blast on the whistle, and the same signal on the general alarm.
• B. 3 short blasts on the whistle and 3 short rings on the general alarm bells
• C. One long blast on the whistle and a long ring on the general alarm
• D. Two long blasts on the whistle and no alarm

Answer: (A)

Fire on board is signaled with a distinctive pattern: more than six short blasts followed by one long blast on the whistle, and the same pattern on the general alarm. This combination is designed to cut through engine and background noise quickly, grabbing attention fast, while the final long blast clearly marks the end of the sequence and identifies it as a fire emergency.

Using the same signal on the general alarm ensures every crew member, no matter where they are on the ship, hears the alert through both the whistle and the ship’s alarm system, providing reliable redundancy in a noisy environment. This pattern is specifically chosen to stand out from other signals, unlike a few short blasts or a single long blast, which wouldn’t communicate fire with the same urgency and clarity.
