On airliners its because you're flying at very high altitudes which means there is very little oxygen and if one of the windows are broken that air will come so if you don't have the oxygen masks you'll die from lack of oxygen
in case of an emergency like there is a gas leak, or there are toxic fumes released into the air, or if the plane is about to crash and people start to panic
What else can I help you with?

Where does oxygen on airplanes come from?
Normal oxygen found on airplanes in the cabin is just air from the ground that is pressurized. However, air coming from emergency masks is from a storage tank or oxygen generator in the cargo hold or above the seats. WRONG: Airplane air is compressed from the outside air by the engines and then cooled down though air-conditioning and filtered. Humidity is then added. The air leaves the plane through ports to keep optimal pressurization (these ports can open and close as necessary). In an emergency, air is created by a chemical oxygen generator, most commonly sodium chlorate, which gives off oxygen when heated. When you don't know something, don't respond; rather than filling in BS information.
How do airplanes protect people from the decreased air pressure when flying at high elevations?
When flying at hight altitudes (+12,000FT) planes pressurize the cabin so passengers can stay conscious without wearing oxygen masks.
What air is in hospital breathing masks?
oxygen
How pollutants decrease the diffusion of oxygen in the lungs?
by gas masks and oxygen packs.
How does sudden decompression cause a plane to crash?
It doesn't--this is just an urban legend. Pressurized airplanes can usually maintain cabin pressure with one or more windows completely missing, but even if they lost all cabin pressure, the pilots would use oxygen masks and the emergency masks would drop in front of the passengers. Then the airplane would descend to under 10,000 feet where you wouldn't need oxygen.
Why are oxygen masks nessesary when flying at high altitudes?
Oxygen masks are necessary at high altitudes because the air pressure decreases, resulting in lower oxygen levels. This can lead to hypoxia, which is a condition where there is insufficient oxygen reaching the body's tissues. Oxygen masks help provide supplemental oxygen to passengers and crew to prevent hypoxia and ensure their safety during high-altitude flights.
Give one use of oxygen?
For oxygen masks for firefighters, scuba divers etc
How oxygen is available in aircraft?
Oxygen is available in emergency overhead masks in passenger aircraft
Why do sick or injured people wear oxygen masks?
The more oxygen the get the faster it diffusses to the cells.
Why are airplanes pressurised?
Modern airliners and aircraft that fly above 15,000 feet are required to be pressurized because the oxygen levels at such high altitudes are not sufficient for the human body's needs. If much time is spent above these altitudes without pressurization or supplemental oxygen, hypoxia can result. The symptoms of hypoxia, or a lack of oxygen in the bloodstream, include nausea, discoloration, disorientation, and severe headaches. Not all airplanes are pressurized, however. Pressurization is limited to airliners, private jets, expensive personal aircaft, and high-altitude military aircraft. An alternative to pressurization is supplemental oxygen masks connected to oxygen tanks somewhere in the aircraft. Pilots are required to wear oxygen masks when flying above 12,500 feet for any longer than 30 minutes. At 14,000 feet, pilots are required to use supplemental oxygen at all times. At 15,000 feet, everyone on board must have supplemental oxygen.
What were the uses of scrap rubber during World War 2?
Tires for trucks and planes soles for shoes gas masks and oxygen masks
