Why is an Oxygen Mask Necessary when Cabin Pressure Drops on a Plane?

First of all, it is necessary to know where these life-saving masks come from and how they work. In emergency situations, passengers can stay on planes when oxygen is needed at high altitudes. from a large oxygen tank Is this oxygen coming out?

Frequency of events requiring the use of oxygen, approximately 10 per billion flight hours. At these rates, “Will it happen to me?” Don’t say that and know that wearing an oxygen mask is more important than you think.

Why is an oxygen mask necessary on airplanes?

Airplanes usually 10,000 meters above sea level or flies at higher altitudes. At these altitudes, the atmosphere thins and the oxygen level and air pressure are insufficient for people to breathe comfortably.

Modern aircraft cabin pressure is generally at a level equivalent to about 2,400 meters above sea level. However, any technical malfunction or problem that may occur in the integrity of the body, sudden drop in cabin pressure may cause. This is where oxygen masks come into play.

What happens if we don’t wear the oxygen mask?

decrease in cabin pressure, “hypoxia” This leads to a condition known as . Hypoxia is also defined as the lack of sufficient oxygen reaching the tissues and causes serious health problems within a few minutes.

When there is not enough oxygen, brain functions are rapidly affected. And within a few minutes loss of consciousness takes place. Continuing lack of oxygen also causes damage to many vital organs such as the heart and brain. Acute oxygen deficiency can also be permanent neurological problems It can also bring with it.

In the past, Helios Airways Flight 522 Incidents such as the accident painfully reveal the importance of oxygen masks. In the accident, most of the cabin crew and passengers lost consciousness due to the decrease in cabin pressure. The plane continued to fly uncontrollably.

How do oxygen masks work?

Oxygen masks, which are automatically activated when the pressure drops in the aircraft cabin, are released from the upper compartment. Each mask is connected to a chemical oxygen generator. Generator; chlorate potassium, iron powder, sodium chlorate Contains chemicals such as:

When you pull the mask towards you, it starts the oxygen flow. firing pin being released and oxygen flow is provided.

All passengers have to do is pull the rubber band of the mask around their head and breathe deeply. With this simple action, the oxygen level can be controlled even in an emergency situation. remain at a sufficient level you can provide.

How long do oxygen masks produce oxygen?

This time is average It is 10 minutes. This is enough time for pilots to descend below 10,000 feet to provide sufficient oxygen.

As you can see, oxygen masks are more vital than you might think. That’s why For your flight safety It is always useful to pay attention to the emergency instructions of the cabin crew.
