Bibliography

This European Standard specifies minimum requirements for self-contained open-circuit compressed air breathing apparatus for escape only, incorporating a hood.Such equipment is intended for use in work situations where the risk on overpressurisation of the pressure vessels with their valves due to hot environmental conditions is low.Laboratory and practical performance tests are included for the assessment of compliance with the requirements.This European Standard does not apply to apparatus for work or to diving devices.
