    A SCSR is usually a closed-circuit breathing apparatus [1] with a chemical oxygen generator or a compressed oxygen cylinder and a carbon dioxide absorber. SCSRs are most commonly used in some coal mines, are intended for one person, and usually supply at least one hour of oxygen. SCSRs are intended to facilitate escape from mines after a fire ...

    They are used in escape breathing apparatus of several kinds (escape hoods), [34] and as a route for supplementary oxygen (oxygen hoods). Breathing hoods with full length visors are commonly used with free-flow supplied air respirators for industrial work like in spray painting, boatbuilding, and woodworking workshops. [35]

    Davis breathing apparatus tested at the submarine escape test tank at HMS Dolphin, Gosport, 14 December 1942. The DSEA rig chiefly addressed the problem of anoxia threatening a person ascending through water, by providing oxygen; and the associated risk of lung over-pressure injury as underwater pressure reduces with reducing depth, which it addressed by managing oxygen pressures.

    en.wikipedia.org/wiki/Rebreather

    Davis apparatus, Self-contained breathing apparatus, Escape hood A rebreather is a breathing apparatus that absorbs the carbon dioxide of a user's exhaled breath to permit the rebreathing (recycling) of the substantial unused oxygen content, and unused inert content when present, of each breath.
