2. Emergency oxygen system - Wikipedia

   en.wikipedia.org/wiki/Emergency_oxygen_system

   Most commercial aircraft that operate at high flight altitudes are pressurized at a maximum cabin altitude of approximately 8,000 feet. On most pressurized aircraft, if cabin pressurization is lost when the aircraft is flying at an altitude above 4,267 m (14,000 feet), compartments containing the oxygen masks will open automatically, either above or in front of the passenger and crew seats ...

   The oxygen source may be chemical oxygen generators, high pressure portable gaseous oxygen storage systems (gas cylinders), on-board oxygen generating systems (oxygen concentrators), or liquid oxygen systems. [4] Chemical oxygen generation is commonly used on large commercial aircraft as a source for the emergency oxygen system for passengers ...

6. Cabin pressurization - Wikipedia

   en.wikipedia.org/wiki/Cabin_pressurization

   The oxygen systems have sufficient oxygen for all on board and give the pilots adequate time to descend to below 8,000 ft (2,438 m). Without emergency oxygen, hypoxia may lead to loss of consciousness and a subsequent loss of control of the aircraft. Modern airliners include a pressurized pure oxygen tank in the cockpit, giving the pilots more ...

   en.wikipedia.org/wiki/Chemical_oxygen_generator

   A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture. The mixture has an indefinite ...
