Travel can be nervous. And for some people, the nerves worsen when traveling is involved in an airplane.
The risk of something on an airplane is minimal, and the accident rate continues to decrease to historical low every year, according to Boeing.
One airline pilot has decided to explain what to do if an airplane occurs on an airplane so that travelers are more ready to travel. It is important for the pilot to listen to what the cabin crew is saying, showing the video of a girl who shares how to listen to the safety instructions of the cabin crew saying, “Do not hurt your emotions.” Is shared.
“When the flight attendant said,” When an emergency happens, the oxygen mask comes down, it has reached the top, lowering the oxygen mask, and applying an oxygen mask before helping others. He is familiar, “he said.
“And I think the most important part of the presentation is the pull -down of the oxygen mask,” he said. Use a mask.
However, the truth is a little more complicated because of the chemical reaction to provide oxygen to passengers.
“The reality is an oxygen bottle in the aircraft, and 99 % of them are actually solid chemicals,” he said. “I am neither a biochemical engineer nor a chemist, but it is essentially a sodium chlorate type mixture, and when the oxygen mask is reduced, it releases a firing pin that generates a small explosion that ignites burning candles. The by -product is oxygen.
“So there is a much more complicated mechanism on your seat, you will launch it, you will start to burn and give oxygen. It's an oxygen bottle sitting on you. Not only. “
For this reaction, he explained that it was necessary to actually pull an oxygen mask before passengers put it in order to start a chemical reaction.
“And it's just a burn, so it doesn't last long. It's not necessarily required for a long time. Basically, there is no oxygen if the aircraft is highly reduced. Concentration to maintain a very long consciousness.
This may be scary, but he needs to wear it for a few minutes until the pilot can reduce the amount of oxygen that has enough oxygen to breathe without the help of the mask. I revealed that.
However, maintaining a mask that requires a mask for a long time has a safety risk. It's more complicated than lowering, wearing oxygen, or breathing. “
Despite the help of the pilot, people received comments and did not know how difficult it was to pull.
“Can you pull too violently? I'm afraid of pulling the tube at the moment of panic,” said another user. The hose is folded and the activation pin is folded. If you pull violently, the hose will be three times longer than it is now. You are not pulling the end of the hose, just in the middle. “
The second person said: “Wait, we will never say this why this feels like the most important part.”
