Last Updated: 2/18/2025 5:55:43 PM

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 the NFPA
National Fire Protection Association
1981 requirements of NFPA
National Fire Protection Association
1970 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.

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

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.
