GENERAL EMERGENCY SIGNAL 

The general emergency signal consists of seven or more short blasts followed by one long blast on the ship's whistle or siren, and, in vessels where such systems are required, on an electrically operated bell or similar. On hearing the general emergency signal the crew and passengers (if any) must proceed to their assembly or muster stations and carry out the muster list.

OTHER EMERGENCY SIGNALS

Other emergency signals may include manually or automatically activated fire alarms, signals not requiring the muster of passengers or the whole crew, man oveboard alerts, etc. These other signals may be accompanied by the general emergency signal sounded on the whistle or siren.

ABANDON SHIP SIGNAL

The abandonship order is used at the master's discretion and may be given by a signal or by word of mouth, but arrangements must be made to ensure that everyone on board, including those in emergency parties in remote locations will receive it. If the abandon ship order is by a signal it must not be able to be confused with any other signal.

All signals and the abandon ship order must be described in the emergency instructions for crew and passengers.
