If you hear a continuous blast of the whistle for not less than 10 seconds supplemented by the continuous ringing of the general alarm bells for not less than 10 seconds, what does this indicate?
• SOLAS emergency signals used on ships • Difference between signals for fire and emergency, abandon ship, and man overboard • Role of the general alarm bells versus the ship’s whistle
• Think about which situation requires everyone on board to be alerted immediately, no matter where they are, using the LOUDEST and most GENERAL signal possible. • Consider which emergencies might also be announced by voice or PA system, instead of (or in addition to) the full whistle plus continuous general alarm. • Ask yourself: for which event do you practice full-ship drills most often with this exact combination of whistle and general alarm?
• Verify in your notes or training manual what the standard emergency signal is (whistle + general alarm) and what situation it is specifically assigned to. • Check whether man overboard usually has a sound or PA announcement that is more localized or specific, rather than a full-ship continuous alarm. • Confirm that dismissal from a boat drill is normally given by voice/PA or short signals, and not by a long continuous whistle and general alarm.
