SEL Number: 01AR-01-SCBA
Title: SCBA, CBRN


Last Updated: 3/18/2024 8:55:32 AM

Previous SEL Number: 01AR-01-SCBA

Description: CBRN
Chemical, Biological, Radiological, Nuclear
SCBA
Self Contained Breathing Apparatus
- Self-Contained Breathing Apparatus certified as compliant with NFPA
National Fire Protection Association
1981 and certified by NIOSH
National Institute for Occupational Safety and Health
as compliant with the CBRN
Chemical, Biological, Radiological, Nuclear
approval criteria. Worn with multiple ensemble configurations.

ImportantFeatures: SCBA
Self Contained Breathing Apparatus
consists of a harness, air cylinder, first stage regulator, low pressure hose, second stage regulator, end-of-service-time indicator (EOSTI) and facepiece. SCBA
Self Contained Breathing Apparatus
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
Code of Federal Regulations
Part 84. Variations exist in harness design, types of cylinders, and facepieces.

The 2019 edition of NFPA
National Fire Protection Association
1981, the eighth edition, includes editorial corrections, paragraph numbering changes, and reference document updates. A definition of universal emergency breathing safety systems (UEBSS) is added and the test series is updated to include UEBSS. Also, the standard now requires demand certification by NIOSH
National Institute for Occupational Safety and Health
and a nonelectronic transmission system at a minimum for voice communications. Breathing rate can now be reported by the data logging software. Updated figures for the UEMSS male and female fittings are provided, and requirements for UEBSS location marking specify that it be readily visible and contrasting. A new strength of connection between the facepiece and second stage regulator performance requiement and associated test has been added. NFPA
National Fire Protection Association
has approved an Emergency Response and Responder Safety Document Consolidation Plan, with implementation planned in 2024. NFPA
National Fire Protection Association
1971, NFPA
National Fire Protection Association
1975, NFPA
National Fire Protection Association
1981, and NFPA
National Fire Protection Association
1982 will be consolidated into a new standard NFPA
National Fire Protection Association
1970, Standard on Protective Ensembles for Structural and Proximity Firefighting, Work Apparel and Open-Circuit Self Contained Breathing Apparatus (SCBA
Self Contained Breathing Apparatus
) for Emergency Services, and Personal Alert Safety Systems (PASS).

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

CBRN
Chemical, Biological, Radiological, Nuclear
SCBA
Self Contained Breathing Apparatus
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 or 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
Chemical, Biological, Radiological, Nuclear
SCBA
Self Contained Breathing Apparatus
. Some CBRN
Chemical, Biological, Radiological, Nuclear
agents may not present immediate effects from exposure, but can result in delayed impairment, illness, or death. Direct contact with CBRN
Chemical, Biological, Radiological, Nuclear
agents requires proper handling of the SCBA
Self Contained Breathing Apparatus
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
Self Contained Breathing Apparatus
after decontamination.

NIOSH
National Institute for Occupational Safety and Health
Cautions and Limitations Statement: SCBA
Self Contained Breathing Apparatus
should not be used beyond 6 hours after initial exposure to chemical warfare agents to avoid possibility of agent permeation.

CBRN

SCBA
Self Contained Breathing Apparatus
facepieces must be specifically fit tested for individual first responders in accordance with OSHA 29 CFR
Code of Federal Regulations
Part 1910.134. Other use considerations are provided in OSHA Title 29 CFR
Code of Federal Regulations
Sections 1910.120 and 1910.134, and NFPA
National Fire Protection Association
1500, Standard on Fire Department Occupational Safety and Health Program. Selection, care, and maintenance are covered in NFPA
