SCBA 4


SCBA 4 :

Self Contained Breathing Apparatus, or air-pack, worn by firefighters to protect against breathing toxic fumes and smoke, or where the air has insufficient oxygen. Often incorrectly called "oxygen mask" by laypersons. Typically of open circuit style, with a supply of compressed air, where expired air is exhausted, rather than closed circuit where it is filtered, re-oxygenated from compressed oxygen, and inhaled again - which is used where an air supply is needed for an extended period (up to four hours)
