Cruising on a ship is a risky job. The danger of working on a ship is that any accident on board the ship leads to a struggle for buoyancy. There are various ship alarms - signals that notify the ship's crew of danger and allow timely response to any incidents.
Alarm on the ship
Any accident on a ship can lead to serious consequences for the entire ship. However, the alarm is raised not only in case of danger to the ship, but also in case of danger to a crew member. Each member of the ship's crew is always in his place, he is competent and trained not to panic in critical situations. In the event of an objective or educational need, it will certainly be included in the overall struggle for the buoyancy of the ship. Ship alarms are a sophisticated warning system for the entire crew. They not only give general information about the problem, but also let the crew know exactly what happened. Depending on the type of alarm, each crew member is required toperform the actions prescribed for him with the fullest dedication.
All actions for any of the alarms are fully regulated by the emergency schedule. Regardless of the type of alarm, there should be no panic on the ship. All rescue and emergency equipment is secured in special rooms located in the most logical parts of the ship. In this way, each member of the crew can quickly reach the equipment or survival craft.
Ship alarms on each ship may be different. As a rule, it depends on what waters the ship is sailing in. There are alarms that are on every ship, and there are specific ones. The list of all alarms, as well as the necessary actions of the crew members for each of them, are in the logbook and in the emergency schedule.
What triggers the alarm?
Timely notification of all, without exception, members of the ship's crew is a vital necessity. The warning system on each ship is duplicated. There are basic and auxiliary means of alerting the crew. Thus, the ship is protected from failure of all means of warning.
In most cases, ship alarms are given by the so-called loud ringing bell, it is also often called a bell. This is an advanced electrical crew warning system. Similar calls are located on each deck and are triggered at the same time when an alarm command is received.
It happens that the call of the loud fight is damaged and there is no way to sound the alarm just for them. ATIn this case, the ships always have ship's whistles and sirens. Whistle is a broad term. In this case, it assumes that the signal can be sent by any device that is loud enough and able to signal in the right way.
Emergency alert
Ship alerts on a ship can be filed all at once. The ship's emergency alarm gives almost all alarms, with the exception of some. Any means may be used to generate an emergency alarm. Sometimes all means are applied at once.
Types of alarms on ships
There are general alarms and special ones. General alarms operate on every ship, including the military, and are given in the same way. Crew actions may vary depending on the ship.
The main types of ship alarms are:
- General ship.
- Man overboard.
- Boat.
Special alarms:
- Pirate attack.
- Combat alert.
General alarm
This alarm is given if the ship is in danger and it is necessary to prepare both the ship and its crew in advance. This usually applies to storms and passages through icy waters. However, the same alarm is announced in case of fire, a hole in the hull and other dangerous accidents. This alarm is signaled by a continuous loud ringing signal. The duration of the signal is about 30 seconds. The signal is repeated several times, the reasons for the signal are announced through the loudspeakers.
Boat alert
When it becomes clear that the ship can no longer be saved, a general evacuation is announced. To alert the crew, 8 signals are given. Of these, 7 are short and 1 is long. Immediately after the signal has been given, absolutely every sailor, without creating panic, begins to act on alarm. It is necessary to dress warmly, put on a life jacket, take documents and follow the instructions in the emergency log. All ship's alarms and their signals may be given in an unusual way, depending on the circumstances. Not every situation can be worked out in exercises. This is especially true of the boat alarm, because it is served under the worst circumstances.
Man overboard
If someone falls into the sea, a "man overboard" alarm is announced. It is given by three long signals. Immediately after receiving the alarm, the rescue team prepares the rescue operation. A sailor who threw a lifeline to a drowning person must point at the person overboard with his hand and not lose sight of him.
Alarm actions
Each ship has a log book and an emergency schedule. They carefully spell out the types of alarms on this ship and the actions to be taken in response to ship alarms. This is a very detailed list of responsibilities. Depending on which alarm was given, each sailor performs the actions prescribed for him. Such a strict regulation of sailors' duties makes it possible to completely eliminate panic and chaos on the ship inin the event of an emergency.
