People need to be rescued in time when there is an accident or an emergency landing during water activities. At this time, water rescue equipment plays an important role. Water rescue equipment is mainly composed of floating equipment, communication equipment and signal equipment. These equipment can help rescuers in rescue.
1. Water rescue equipment: floating equipment
Floating equipment of water rescue equipment mainly includes lifeboats, life vests and waterproof and cold-proof flight suits. The lifeboat is an inflatable rubber boat that can carry about 4-7 people. After the airboat of the inflatable boat is inflated, it generates buoyancy on the water to prevent it from sinking. When not in use, the lifeboat is folded and packed in a canvas bag. When it is used in an emergency, the canvas bag is opened and the lifeboat can be automatically inflated. The life vest and waterproof and cold-proof suit are used by the crew on board when they leave the aircraft. Floating gear worn on the body: cold-proof flying suit, which can protect the personnel on board from freezing when the water temperature is zero. Once the waterproof flight suit is in contact with water, a layer of waterproof suit is formed on the surface to ensure that the crew on the plane will not be wetted by sea water after falling into the water.
2. Water rescue equipment: communication equipment
The communication equipment is a small transceiver. After this small transceiver is soaked in seawater, the performance of the machine does not change, and the communication distance is 100 kilometers.
3. Water rescue equipment: signal equipment
There are many types of signal equipment, which can be divided into visual signal equipment, audio signal equipment and signal flags. Visual signal equipment includes reflectors used during the day, sea water dyes, smoke, etc., and fire lights, flash lights, incandescent lamps, flash bombs, tracers, signal bombs, etc., used at night. The audio signal equipment includes shooting pistols, whistles, sirens, and microphones. The signal flag is divided into three sides: red, green and white. The crew on board used these devices to signal various signals and request rescue.
Although the water rescue equipment is relatively complete, its life-saving capabilities are limited. The personnel on board should contact professionals as soon as possible and take measures to strive for a longer period of time to survive in order to wait for rescue.
