Emergency Signals and Alarms on Ships

Emergency Alarms on a Ship

• Seven short blasts followed by one long blast on the ship's whistle or bell is recognised as the general emergency alarm on a ship.
• The purpose of emergency signals or alarms on a ship is to alert crew and passengers of a life-threatening situation, such as a fire, flooding, or man overboard, and to initiate immediate response and evacuation procedures.
• The ship's fire alarm signal is sounded by a continuous ringing of the alarm bell or a high-pitched, continuous siren, usually accompanied by flashing lights or strobes.
• Emergency signals or alarms are installed in strategic locations throughout the ship, including cabins, corridors, engine rooms, and bridge, to ensure that they can be heard and seen by all on board in the event of an emergency.
