Long-distance sailing on a ship is a risky job. The danger of working on a ship is that any accident on board a ship leads to a fight for buoyancy. There are various ship alarms - signals that alert the crew of a ship about danger and allow you to respond to any incidents in a timely manner.
Ship alarm
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 its place, it is competent and trained not to panic in critical situations. In the event of an objective or educational need, he will certainly be included in the general struggle for the buoyancy of the vessel. Ship alarms are a well-developed warning system for the entire crew. They not only provide general information about the problem, but also make it clear to the crew what exactly happened. Depending on the type of alarm, each crew member is obliged to carry out the actions prescribed to him with the utmost dedication.
All actions for any of the alarms are fully regulated by the emergency schedule. Regardless of the type of alarm, panic should not occur on the ship. All rescue and emergency equipment is fixed in special rooms located in the most logical parts of the ship. Thus, each crew member can quickly get to equipment or rescue equipment.
Ship alarms on each ship may be different. As a rule, it depends on the waters in which the ship floats. 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 ship's log and in the emergency schedule.
What is the alarm?
Timely notification of all, without exception, members of the crew of the ship 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 the failure of all warning devices.
In most cases, ship alarms are given by the so-called ringing of a loud battle, it is often called a bell. This is an advanced electric crew alert system. Similar calls are located on each deck and are triggered at the same time upon receipt of an alarm announcement command.
It happens that a loud battle bell is damaged and there is no way to give an alarm to them. In this case, ships always have ship whistles and sirens. A whistle is a broad term. In this case, he assumes that the signal can be supplied by any device that has sufficient volume and is capable of supplying the signal as needed.
Emergency alarm
Ship alarms on a ship can be triggered at once. The general emergency alarm gives almost all alarms, with the exception of some. Any means may be used to give an emergency alarm. Sometimes all means are applied at once.
Types of ship alarms
There are general and special alarms. General alarms operate on each ship, including the military, and are given in the same way. Crew actions may vary by ship.
The main types of ship alarms are:
- General ship.
- Man overboard.
- Dinghy.
Special Alarms:
- The attack of the pirates.
- 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 passageways through ice water. However, the same alarm is announced in case of fire, a hole in the housing and other dangerous accidents. This alarm is generated by a continuous ringing tone of a loud battle. The duration of the signal is about 30 seconds. The signal is duplicated several times, the reasons for the signal are communicated through the speakers.
Boat alarm
When it becomes clear that the ship cannot 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 was given, absolutely every sailor, without creating a panic, begins to act on alarm. It is necessary to dress warmer, put on a life jacket, take documents and follow the instructions of the emergency log. All ship alarms and their signals can be given in an unusual way, depending on the circumstances. Not every situation can be worked out in exercises. This is especially true for boat alarm, because it is served under the most nasty circumstances.
Man overboard
In case someone fell into the sea, an alarm “man overboard” is announced. It is given by three long signals. Immediately after receiving the alarm, the rescue team prepares a rescue operation. A sailor who threw a lifebuoy to a drowning person should point to a person overboard with his hand and not lose sight of him.
Alarm Actions
Each ship has a ship log and emergency schedule. The types of alarms on this ship and actions on ship alarms are carefully spelled out in them. This is a very detailed list of responsibilities. Depending on what kind of alarm was given, each sailor performs the prescribed actions. Such a strict regulation of the duties of sailors allows us to completely eliminate panic and chaos on the ship in the event of an emergency.
