Principles of Airplane Oxygen Masks

■ Principles of Airplane Oxygen Masks

While reading the book, the story of <#potassiumchlorite> came up, and I heard it was used in an airplane oxygen mask, so I looked at it.

In the event of an emergency (such as a puncture on the wall of a plane or a sudden drop in altitude), an orange (yellow) mask falls off from the overhead rack. If you pull the mask and cover your nose and mouth, oxygen will be released. If a sudden depressurization occurs at an altitude of a plane carrying 10 to 13 kilometers, you will faint within 30 to 90 seconds. Also, oxygen is very scarce at that altitude, so you have to use it to avoid meeting your ancestors quickly.

So, are they carrying oxygen tanks for 2 to 300 people directly on the vanguard? Or. To load that amount of oxygen tank, you have to carry a tank the size of a body of a vanguard. There's no such space in a vanguard where you have to receive at least one more customer and adjust the balance of payments. Moreover, even if oxygen ignites the flame, the vanguard will explode, so it's very dangerous. Then what?

The oxygen mask on the passengers' heads is connected to a solid can containing potassium chlorate or sodium chlorate. When the passenger pulls the mask, the ignition pin falls out and generates heat, and this heat releases oxygen as it heats up potassium chlorate or sodium chlorate. This is why this is called a chemical oxygen generator. This small barrel produces oxygen that four people can breathe for about 10 to 14 minutes, and in the meantime, the length of the vanguard should quickly descend to 10,000 feet (2 to 3,000 meters) to enable natural breathing.

(*Potassium chlorate is also present in matches. A match is a piece of wood coated with potassium chlorate. The surface of the matchbox is covered with soaked glass powder and diatomaceous earth to easily generate frictional heat, and if the match is drawn here, the frictional heat will ignite.)
