Fire breathing is the act of making a plume or stream of fire by creating a precise mist of fuel from the mouth over an open flame. Regardless of the precautions taken, it is always a dangerous activity, but the proper technique and the correct fuel reduces the risk of injury or death.
In firefighting, the policy of two-in, two-out refers to United States Occupational Safety and Health Administration (OSHA) policy 29 CFR 1910.134(g)(4)(i). [1] The respiratory protection standard requires that workers engaged in fighting interior structural fires work in a buddy system; at least two workers must enter the building together, so that they can monitor each other's whereabouts as ...
Some types are also referred to as a compressed air breathing apparatus (CABA) or simply breathing apparatus (BA). Unofficial names include air pack, air tank, oxygen cylinder or simply pack, terms used mostly in firefighting. If designed for use under water, it is also known as a scuba set (self-contained underwater breathing apparatus).

In the United States, the National Fire Protection Association sets standards for PASS devices in NFPA 1982. [ 1 ] The PASS device is normally used in conjunction with breathing apparatus; it is a small, battery-powered device attached to the self-contained breathing apparatus (SCBA) harness which enables the firefighter to summon help by ...
An air and light unit, also known as a breathing support unit or mobile air unit, is a specialized firefighting apparatus used by first responders to provide supplemental lighting and self-contained breathing apparatus cylinders and cylinder filling services at the scene of an emergency. [1]
The concept has important practical use in fire safety engineering. For instance, to safely fill a new container or a pressure vessel with flammable gases, the atmosphere of normal air (containing 20.9 volume percent of oxygen) in the vessel would first be flushed (purged) with nitrogen or another non-flammable inert gas, thereby reducing the ...
A breathing set intended for use in hyperbaric environments must not supply gas with a toxic concentration of oxygen. [31] Most breathing sets for hyperbaric use are ambient pressure underwater breathing apparatus, but breathing apparatus may be necessary in a pressurised tunnel or caisson due to contamination by hazardous materials.
