Underwater breathing apparatus
http://dbpedia.org/resource/Underwater_breathing_apparatus an entity of type: Thing
Underwater breathing apparatus is equipment which allows the user to breathe underwater. The three major categories of ambient pressure underwater breathing apparatus are:
* Open circuit scuba, where the diver carries the gas supply, and exhaled gas is exhausted to the environment
* Rebreather scuba, where the diver carries the gas supply, and exhaled gas is recycled for further use, and
* Surface supplied diving equipment, where the gas supply is provided from the surface through a hose in a diver's umbilical Two other types may also be identified:

* Escape sets provide a limited amount of breathing gas to allow the user to reach the surface from a disabled vessel or vehicle.
* Atmospheric pressure underwater breathing apparatus is also used in the form of armoured atmospheric diving suits, which maintain an internal pressure approximating surface pressure.
