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:
“Excuse me sir. There’s breathing in my barn.”
—R.C. Sherriff (1896–1975)
“The gods being always close to men perceive those who afflict others with unjust devices and do not fear the wrath of heaven.”
—Hesiod (c. 8th century B.C.)
“I believe that water is the only drink for a wise man: wine is not so noble a liquor; and think of dashing the hopes of a morning with a cup of warm coffee, or of an evening with a dish of tea! Ah, how low I fall when I am tempted by them! Even music may be intoxicating. Such apparently slight causes destroyed Greece and Rome, and will destroy England and America.”
—Henry David Thoreau (1817–1862)
