Before takeoff travel aircraft, the crew tells passengers a summary of the various safety procedures, the most interesting is the existing oxygen masks above the seats, which falls directly in front of the passenger if the cabin suddenly suffer from air pressure, helping those masks passengers to breathe for a few minutes . But the question is: Where do you get the plane on oxygen? Will commercial aircraft carrying a huge tank of oxygen for emergencies?If you answered yes to the last question, some might wonder whether the safety of the plane that carries with it a huge reservoir of oxygen and fly it into the air ?! If the answer is no, so where are getting oxygen to supply its passengers through the masks?The short answer is that most commercial aircraft include chemical oxygen generating system, when low oxygen mask starts the chemical reaction to produce oxygen as a product Thanoa.kma we all know that air pressure decreases as altitude increases, and thus the air becomes very difficult to breathe. In most commercial aircraft, if misfire pressure in the cabin above the height of 14,000 feet, the oxygen masks dangling automatically over every chair in the plane. Usually, what is an additional mask for each row to emergencies.These masks are not required because they are worn all the time, as they provide oxygen for a short time only, where the pilots then to drop to a safe area where the outside air becomes Negotiable breathe again.
