Alarms on life rafts, boats and boats, alarms and communications for the distressed at sea.

In order to attract the attention of passing ships, flying helicopters and airplanes, rescue rafts, boats and boats there is a stock of signaling equipment. However, signaling should be used wisely when there is confidence that a distress signal can be seen or heard. This is especially true for pyrotechnic products, the number of which on rafts and boats is limited. It is also necessary to economically consume the battery of the signal light.

The use of pyrotechnic signaling means – parachute missiles and signal cartridges (false fires) – follows the instructions available on the pyrotechnic means themselves or enclosed in plastic bags in which these signaling means are stored.

In the daytime, rockets and signal lights are clearly visible from a distance of 2-3 miles, at night – from a distance of 6-9 miles. Signaling with the help of pyrotechnic means must be entrusted to a person who constantly must be ready for this. The signal light can only be used at relatively short distances..

In sunny weather during the day, a good signaling device is a signal mirror equipped with an aiming device, with the help of which you can precisely point the sunny “bunny” at distant objects. The sun’s rays reflected from the mirror are visible from the ship to the range of the visible horizon, and from the plane – at least 15 miles. Instructions on how to use the signal mirror are on its cover..

For a successful signal, the mirror must be held in hand so that a ship or an aircraft that receives a signal is visible in its sighting hole on the top wing. To successfully hit the “sun bunny” in the target and detect it, you need to deploy a mirror so that the sun ray passing through the sighting hole reflects from the lower leaf on the inner surface of the upper leaf in the form of a light circle, coinciding with the sighting hole.

The victim is only required to turn on the emergency radio station at the scheduled time. Then, simply controlling its operation by a signal light. Much attention should be paid to protecting the emergency radio station from water. To do this, immediately after the end of work, it should be removed in a rubber cover.
