Respiratory protective devices for use against chemical, biological, radiological and nuclear (CBRN) agents. Positive-pressure compressed air line equipment. Specification | Status: Confirmed, Current

1 Scope This British Standard specifies requirements for compressed air line breathing apparatus with positive pressure demand valve for use with a full face mask as a respiratory protective device intended to be used during firefighting, rescue, evacuation, escape, hazard containment and decontamination, and similar activities by emergency first responders (e.g. fire, ambulance, police, and associated civilian agencies and workers) in areas containing and contaminated by chemical, biological, radiological and nuclear (CBRN) agents. This British Standard is applicable to Type CBRN3 devices, which provide an enhanced level of resistance to liquid and gaseous chemical agent permeation and penetration. This British Standard contains requirements for testing and marking. Requirements for methods of and criteria for decontamination of respiratory protective devices (RPD) are not specified in this British Standard.

NOTE Compressed air line breathing apparatus conforming to this British Standard might be suitable for use in situations other than those involving the specific CBRN agents identified in the standard.
