Escape breathing apparatus, also called escape respirators, escape sets, self-rescuer masks, emergency life saving apparatus (ELSA), emergency escape breathing devices (EEBD), and Respiratory Protective Smoke Escape Devices (RPED), [1] [2] are portable breathing apparatus that provide the wearer with respiratory protection for a limited period, intended for ...
SCBAs usually come with full-facepieces, [11] but can also come with half-mask or mouthpiece in demand or pressure-demand mode, though use of mouthpieces are limited to escapes only, as of 1987. [4] Hoods and helmets are limited to continuous flow mode only, and are also used in air-line respirators in addition to escape-only SCBAs. [4] [12]
An escape respirator may have no component that would normally be described as a mask, and may use a bite-grip mouthpiece and nose clip instead. Alternatively, an escape respirator could be a time-limited self-contained breathing apparatus. For hazardous environments, like confined spaces, atmosphere-supplying respirators, like SCBAs, should be ...
SARs may be either constant-flow or pressure-demand respirators. Constant-flow respirators supply a steady stream of air, some of which escapes from the wearer end unbreathed. Pressure-demand respirators supply air only when the pressure in the wearer's mask drops (that is, when they inhale). This saves air but allows more inwards leakage.
