Previous SEL Number: 01AR-01-SCBT

Description: CBRN SCBA - Self-Contained Breathing Apparatus certified as compliant with NFPA 1986 Standard on Respiratory Protection Equipment for Tactical and Technical Operations and certified by NIOSH as compliant with the CBRN approval criteria. This type of open-circuit SCBA and combination SCBA /SARs can be used by emergency services organizations for respiratory protection during tactical law enforcement, technical rescue, hazardous materials response, confined space entry, terrorist incident response, and similar operations where oxygen deficiency, particulates, toxic products, products of combustion, or other IDLH atmospheres exist or could exist at the incident scene. This type of SCBA /SAR is not suitable for fire-fighting operations (See 01AR-01-SCBA for fire-fighting SCBA ). 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 2017 edition of NFPA 1986 is the first edition of this standard and includes mandatory and optional design requirements, test methods, and performance criteria for:
- NIOSH certification in accordance with 42 CFR 84
- NIOSH certification as compliant with the Statement of Standard for NIOSH CBRN SCBA
- Facepiece that covers the wearer's eyes, nose, and mouth
- Nonelectric transmission system for voice communications capability
- Optional supplementary voice communications system
- End-of-Service-Time Indicator (EOSTI)
- Optional heads up display (HUD)
- Optional Rapid Intervention Crew/Company Universal Air Connection (RIC UAC)
- Optional Emergency Breathing Safety System (EBSS)

Operating Considerations: Worn in compliance with Incident Commander guidance and with 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.
