Application Summary AI generated
This standard specifies technical requirements, test methods, and inspection rules for self-contained closed-circuit oxygen breathing apparatus designed for escape from hazardous atmospheres. It is applied in industrial settings, mining operations, and emergency scenarios where workers or the public need to evacuate oxygen-deficient or toxic environments, such as during fires or chemical leaks. The standard ensures the apparatus provides reliable oxygen supply and carbon dioxide removal for a specified duration, typically 10-60 minutes, to facilitate safe egress.
