What are the use of aircraft life jackets

When it comes to life jackets, many passengers will think of evacuation at sea.But some passengers have questioned: Why do inland routes still need to be equipped with life jackets?That's because the plane may fly over the river and lake during the flight. If it is necessary to surrender at this time, it is likely to be forced to land on the river or lake, and naturally you need a life jacket.

The life jackets on the plane are divided into two types: red and yellow.The red life jacket is used, and the yellow life jacket is used for passengers.Even if the plane is not forced to land on the water, when the remote land from the airport is forced to land and evacuate, wearing a life jacket can make passengers more conspicuous in the open area, so that rescuers can be found in time, and in areas where low temperatures, strong winds and ice coversIt can also play a role in protecting the cold.

The life jacket is mainly made of nylon materials. There are two airbags up and down. There are two small high -pressure gas cylinders between the airbags distributed on the left and right sides of the life jacket.There are two red inflatable handles on the lower side of the life jacket to pull the red inflatable handle, and the life jacket can automatically inflatable.

There are also artificial gas pipes on both sides on the upper side of the life jacket. This is a unidirectional door similar to the bicycle valve core.When the life jacket is insufficient or leaking, pull out the artificial inflatable pipe, and you can inflatable with your mouth.When holding the top of the artificial inflatable pipe by hand, the gas will be released from the life jacket.There are positioning Lights on the top of the life jacket.It is powered by the seawater battery. After the seawater battery is soaked in water, the positioning light will automatically emit light within a few seconds, and it can continue to use it for 8 hours to 10 hours, which is convenient for the water drop -off to be found at night.

The life -saving jacket is divided into two types: baby life jacket and adult life jacket, which are stored in different positions.First -class and official class passenger life jackets are generally stored under the armrest armrests; ordinary cabin passenger life jackets are placed under the seat, and they can be touched by lowering their heads. Infant life jackets are generally placed under the first row of baby cradle seats in the cabin.Children under the age of age need to use baby life jackets, while children over the age of age can use adult life jackets.

precautions for the use of aircraft life jackets

According to airline staff, the life jacket should be inflated before leaving the plane and before boarding the Ship.This is because the life jacket will be bloated after pumping, and passengers can easily crowd the aisle and exit when they evacuate, which affects the evacuation time.And the inflatable life jacket is easily cut and leaked by sharp items, losing life -saving function.In addition, if the aircraft gets in water, the life jacket will make passengers drift in the cabin, and even pushes even on the cabin ceiling, which is difficult to escape.

When the plane is forced at sea, passengers should not try to swim in life jackets unless they need.Because the temperature of the water and water is low, the average surface water temperature does not exceed 20 degrees Celsius, and the temperature of 13%of the water meter temperature is less than 4 degrees Celsius. Adults in thin clothes survive in the water temperature of 10 degrees Celsius for about 2 hours to 4 hours.Cold water should be reduced as much as possible to save energy.

It is worth noting that parents and passengers should pay attention to the life jacket they wear when they are hugged. The life clothes of the mother and baby should be tied together.For children, only half of the breath of the life jacket you wear after leaving the seat (pull a inflatable handle).In terms of methods, life jackets should be worn on the outermost clothes.
