Civil Aviation Oxygen Masks

- Apr 20, 2017-

Description: On the airliner, oxygen masks are emergency lifesaving devices that provide oxygen to passengers. If the cabin suddenly loses air tightness or encounters other hypoxia situation, passengers can get oxygen mask to replenish oxygen at any time. When the plane flies to a certain altitude, it will pressurize the cabin. If the aircraft cabin loses pressure, it will cause hypoxia, the passenger in the condition of hypoxia will dizziness, loss of consciousness, and even life-threatening. In the case of cabin loss at different heights, the time of hypoxia can be different for people. The higher the flight altitude, the less time to bear. On civil aircraft, everyone has a personal oxygen mask for emergency use, so there is no need to scramble to avoid the use of oxygen masks.

Construction principle: Oxygen masks are connected to an automatic coupler through a slender rubber oxygen supply tube and a card joint. The oxygen continues to flow into the mask's gas storage bag. The gas storage bag is first stored in gas and then rises up to accommodate a certain amount of oxygen. The air inlet valve on the mask allows the oxygen to enter when the passenger is sucked into the air in deep suction.

How to use: In the case of the aircraft cabin decompression, the oxygen cover will be automatically thrown from the roof. Above the passenger seat, there is an oxygen mask emergency manual release words, there is a "push" mark. When pushed, oxygen masks are automatically lowered to the passengers. On the release board, how to use the graphics and text description. Passengers should follow the instructions correctly.
