Previous SEL Number: 01AR-01-SCBA

Description: CBRN SCBA - Self-Contained Breathing Apparatus certified as compliant with NFPA 1981 and certified by NIOSH as compliant with the CBRN approval criteria. Worn with multiple ensemble configurations.

ImportantFeatures: SCBA consists of a harness, air cylinder, first stage regulator, low pressure hose, second stage regulator, end-of-service-time indicator (EOSTI) and facepiece. SCBA are typically rated for 30, 45, and 60 minutes of usage time, but may be rated for other usage times in accordance with 42 CFR Part 84. Variations exist in harness design, types of cylinders, and facepieces.

The 2013 edition of NFPA 1981, the seventh edition, represents a complete revision of the standard. Among the many changes included in this edition are new requirements, test methods, and performance criteria for:

- Emergency Breathing Safety Systems (EBSS) - Buddy Breathers
- End-Of-Service-Time-Indicators (EOSTI) to be set at 33% of the remaining cylinder air volume for 30, 45, and 60 minute cylinders
- SCBA facepiece (mask) test methods and performance criteria for lens radiant heat, convective heat and flame resistance tests
- Speech intelligibility and transmission tests when wearing the SCBA

Operating Considerations: Worn in conjunction with Incident Commander guidance and NFPA-certified ensemble appropriate for threat.

CBRN SCBA are intended for circumstances where the substance involved creates an immediate threat, is unidentified, of unknown concentration, oxygen-deficient, or determined to be immediately dangerous to life and health (IDLH). Such situations would occur where there is still an on-going release with likely gas/vapor exposure, the responder is close to the point of release, and most victims in the area appear to be unconscious or dead from exposure. Stay times in the hazard zone are likely to be short and limited by the breathing air available from the CBRN SCBA . Some CBRN agents may not present immediate effects from exposure, but can result in delayed impairment, illness, or death. Direct contact with CBRN agents requires proper handling of the SCBA after each use and between multiple entries during the same use. Decontamination and disposal procedures must be followed. If contaminated with liquid chemical warfare agents, dispose of the SCBA after decontamination.

NIOSH Cautions and Limitations Statement: SCBA should not be used beyond 6 hours after initial exposure to chemical warfare agents to avoid possibility of agent permeation.

CBRN SCBA facepieces must be specifically fit tested for individual first responders in accordance with OSHA 29 CFR Part 1910.134. Other use considerations are provided in OSHA Title 29 CFR Sections 1910.120 and 1910.134, and NFPA 1500, Standard on Fire Department Occupational Safety and Health Program. Selection, care, and maintenance are covered in NFPA 1852, Standard on Selection, Care and Maintenance of Open-Circuit, Self-Contained Breathing Apparatus.
