Title: Respirator, Air-Purifying, Full-Face, Tight-Fitting, Negative Pressure, CBRN


Last Updated: 3/18/2024 8:56:07 AM

Previous SEL Number: 01AR-02-APR

Description: CBRN
Chemical, Biological, Radiological, Nuclear
Air-Purifying Respirator (APR) (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: NIOSH
National Institute for Occupational Safety and Health
has established specific criteria for air-purifying respirators (APRs) with CBRN
Chemical, Biological, Radiological, Nuclear
approval. These criteria include existing tests established in 42 CFR
Code of Federal Regulations
Part 84, supplemented by additional tests for specific performance against selected chemicals and agents and other areas of performance. The APR must be a full facepiece. Manufacturers may offer facepieces in different materials and different designs.

The NIOSH
National Institute for Occupational Safety and Health
standard supports canister interoperability. The canister's NIOSH
National Institute for Occupational Safety and Health
label is color-coded OD (olive drab) green with black font, and lists the type of agents against which the canister is rated.

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

NIOSH
National Institute for Occupational Safety and Health
has listed the following limitations for CBRN
Chemical, Biological, Radiological, Nuclear
APR:
1. Not for use in atmospheres containing less than 19.5 percent oxygen.
2. Not for use in atmospheres immediately dangerous to life or health or where hazards have not been fully characterized.
3. When used at defined occupational exposure limits, the rated service time cannot be exceeded. Follow established canister change schedules or observe End of Service Life Indicators to ensure that canisters are replaced before breakthrough occurs.
4. Failure to properly use and maintain this product could result in injury or death.
5. Follow the manufacturer's User Instructions for changing canisters.
6. All approved respirators shall be selected, fitted, used, and maintained in accordance with MSHA, OSHA, and other applicable regulations.
7. Use replacement parts in the configuration as specified by the applicable regulations and guidance.
8. Refer to User Instructions and/or maintenance manuals for information on use and maintenance of these respirators.
9. Consult manufacturer's User Instructions for information on the use, storage, and maintenance of these respirators at various temperatures.
10. This respirator provides respiratory protection against inhalation of radiological and nuclear dust particles. Procedures for monitoring radiation exposure and full radiation protection must be followed.
11. If, during use, an unexpected hazard is encountered such as a secondary CBRN
Chemical, Biological, Radiological, Nuclear
device, pockets of entrapped hazard or any unforeseen hazard, immediately leave the area for clean air.
12. Use in conjunction with personal protective ensembles that provide appropriate levels of protection against dermal hazard. Failure to do so may result in personal injury even when the respirator is properly fitted, used, and maintained.
13. Some CBRN
Chemical, Biological, Radiological, Nuclear
agents may not present immediate effects from exposure, but can result in delayed impairment, illness, or death.
14. Direct contact with CBRN
Chemical, Biological, Radiological, Nuclear
agents requires proper handling of the respirator 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 respirator after decontamination.
15. The respirator should not be used beyond eight (8) hours after initial exposure to chemical warfare agents to avoid possibility of agent permeation. If liquid exposure is encountered, the respirator should not be used for more than two (2) hours.
