Breathing Devices Used Out of Water
Breathing devices operating on the above principles are not only used underwater, but in other situations where the atmosphere is dangerous — little oxygen, poisonous, etc.
- Firefighting
- Other jobs out of water, e.g., welding in a confined space
- Mining, especially mine rescue
- Operations in enclosed or poorly ventilated areas, e.g., large fluid or gas containers.
- SCAMP (Supercritical Air Mobility Pack) is an out-of-water liquid-air open-circuit breathing set designed by NASA by adapting space suit technology. Its maker claims that a man wearing it can crawl through a hole 50 centimetres (20 in) square.
These devices are called Self-Contained Breathing Apparatus (SCBA). (The initials SCBA have had other meanings.) The first open-circuit industrial breathing devices were designed by modifying the design of the Cousteau aqualung. Industrial rebreathers have been used since soon after 1900. Rebreather technology is also used in space suits.

Famous quotes containing the words breathing, devices and/or water:
“To fair Fidele’s grassy tomb
Soft maids and village hinds shall bring
Each opening sweet of earliest bloom,
And rifle all the breathing spring.”
—William Collins (1721–1759)
“There is nothing in machinery, there is nothing in embankments and railways and iron bridges and engineering devices to oblige them to be ugly. Ugliness is the measure of imperfection.”
—H.G. (Herbert George)
“If a fish is the movement of water embodied, given shape, then cat is a diagram and pattern of subtle air.”
—Doris Lessing (b. 1919)
