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 ...

Breathing oxygen is delivered from the storage tank to users by use of the following methods: oxygen mask, nasal cannula, full face diving mask, diving helmet, demand valve, oxygen rebreather, built in breathing system (BIBS), oxygen tent, and hyperbaric oxygen chamber. Contrary to popular belief most scuba divers do not carry oxygen tanks.
The equipment must supply breathing gas for all users for at least 15 minutes at a cabin altitude of 8,000 ft at a respiratory minute volume of 30 liters per minute, either by continuous flow or via a demand system, and must not cause a significant increase in oxygen content of the local environment.

Test bench for a miner's closed circuit self-rescuers. A self-contained self-rescue device, SCSR, self-contained self-rescuer, or air pack is a type of closed-circuit SCBA [1] with a portable oxygen source for providing breathable air when the surrounding atmosphere lacks oxygen or is contaminated with toxic gases, e.g. carbon monoxide.
Equipment that supplies or recycles breathing gas other than ambient air in a space used by several people is usually referred to as being part of a life-support system, and a life-support system for one person may include breathing apparatus, when the breathing gas is specifically supplied to the user rather than to the enclosure in which the ...
The aircraft PACKs on the McDonnell Douglas DC-10/MD-11 and Lockheed L-1011 are located in the front of the aircraft beneath the flight deck. Nearly all jetliners have two PACKs, although larger aircraft such as the Boeing 747 , Lockheed L-1011 , and McDonnell-Douglas DC-10/ MD-11 have three.
