Polish Au-2 escape respirator. 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 ...

A self-contained breathing apparatus (SCBA) is a respirator worn to provide an autonomous supply of breathable gas in an atmosphere that is immediately dangerous to life or health from a gas cylinder. [1]

Use of operational flight trainers (OFTs) / weapons system trainers (WSTs) is encouraged for simulated emergencies and scenarios that present significantly increased risk when actually performed in an ...
A properly designed crankcase breather will also be designed in a manner that promotes the scavenging effect, or the creation of suction within the crankcase breather to further aid in the removal of blow-by gases. It is this effect that keeps the crankcase at slightly negative pressure when a properly functioning PCV system is in place. [9]
Inert gas asphyxiation is a form of asphyxiation which results from breathing a physiologically inert gas in the absence of oxygen, or a low amount of oxygen, [1] rather than atmospheric air (which is composed largely of nitrogen and oxygen).
A discrete breather is a breather solution on a nonlinear lattice. The term breather originates from the characteristic that most breathers are localized in space and oscillate in time. [1] But also the opposite situation: oscillations in space and localized in time [clarification needed], is denoted as a breather.
Nitschke's organisation sells suicide kits that contain nitrogen tanks and regulators. [19] He promotes the use of nitrogen and suicide bags with lectures and films, such as Doing it with Betty – in which an elderly woman describes how to make a plastic 'exit' bag, [ 20 ] [ 21 ] and with published materials such as workshop handbooks.
