Respiratory protective devices for self-rescue - Filter self-rescuer - Requirements, testing, marking EN 404:1993

Publication date:   Dec 29, 2001

Scope

This European Standard specifies performance requirements, test methods and marking requirements for filtering devices designed for protection against carbon monoxide as respiratory protective devices for personal escape (in short: filter self-rescuer). Such devices are intended for use against carbon monoxide arising from fire or explosion underground. Laboratory and practical performance tests are included for the assessment of compliance with the requirements. This standard does not include requirements for training devices. However, when such devices are available care should be taken to ensure that only correct parts are fitted to the filter self-rescuer.
