A self-contained self-rescue device, SCSR, self-contained self-rescuer, or air pack is a portable oxygen source for providing breathable air when the surrounding atmosphere lacks oxygen or is contaminated with toxic gases, e.g. carbon monoxide. A SCSR is usually a closed-circuit breathing apparatus 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 or explosion. They are also used by people working with machinery on the surface of a mine or pit, in case they become covered by such materials as coal or sand.[1] Usage of SCSRs for other purposes is discouraged Self-contained Breathing Apparatus Self-rescue Device for Mining Self-contained Self-rescue Device
