This British Standard specifies requirements for positive pressure, self-contained, open-circuit breathing apparatus (SCBA) intended to be used during fire-fighting, 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 contains requirements for testing and marking.
Requirements for methods of and criteria for decontamination of respiratory protective devices (RPD) are not covered in this British Standard.
This British Standard is applicable to Type CBRN3 devices. Type CBRN3 devices provide protection against hazardous particular matter and gaseous and liquid chemical agent permeation and penetration.
NOTE SCBA conforming to this British Standard is also suitable for use in situations other than those involving the specific CBRN agents identified in this British Standard.
