General drills
General drills aboard ship are designed to prepare the crew tp handle emergencies.
By using a standard system of drills it is possible for a man/woman to move from one
ship to another and still know what to do in an emergency. You must know exactly where
your station is and what your job is for each drill or emergency. This important information
is clearly stated on the MUSTER LIST.
No one is excused from any drill unless permission has been granted by the
department head.
All crewmembers must familiarize themselves with the location and duties of their
emergency stations upon reporting on board. Each crewmember is provided with an
individual muster list card, which shows in detail the special duties to perform.
All crewmembers must be instructed in the performance of their special duties.Crew
on watch/watchkeepers will remain on watch on signal for Emergency Drill.
So, drills are held to train you to cope with real emergencies.Muster List tells you
where to go and what to do in a drill or emergency.
Alarm for a real fire may be given at any time and it will be rapid ringing of the ship’s
bells (continuous ringing of the General Alarm Bells for a period of at least 10 seconds).
An announcement is made twice over general announcing system/public address system.
For drill purposes a fire may be assumed to be in a specific place.
The person who discovers an actual fire must give the alarm. He/She must use any
means at hand to spread the alarm.
Once the alarm has sounded personnel nearby should act promptly to check or
extinguish the fire. All other crew members respond to the alarm in accordance with the
Muster List.
Emergency squad/party will assemble with equipment immediately upon the
Emergency Signal.
Steward’s department will assemble and direct passengers, properly dressed and
wearing life jackets, to embarkation stations.
Immediately upon the Fire and Emergency Signal fire pumps must be started, all water doors, ports and air shafts must be closed and all fans and blowers stopped. Fire hoses must be led out in the affected area.
