Description: Wildland Fire Fighting Air-Purifying Respirator (WFF-APR), Certified by NIOSH as compliant with the WFF-APR performance requirements and certified as compliant to NFPA 1984 Standard on Respirators for Wildland Fire Fighting Operations. Depending on the respirator design, this item may include the respirator canister/cartridge component certified as complaint under the NIOSH Wildland Fire Fighting Air-Purifying Respirator approval and the NFPA 1984 standard.

ImportantFeatures: NIOSH has established specific criteria for wildland fire fighting air-purifying respirators. These criteria include existing tests established in 42 CFR Part 84, supplemented by additional tests for specific performance against selected chemical and particulate hazards and other areas of performance. The respirator shall be certified by NIOSH prior to certification to the NFPA 1984 standard. The respirator can be designed as either a full facepiece respirator or a non-full facepiece respirator. Full face piece respirator designs shall accommodate corrective eyewear that is certified by NIOSH as a respirator accessory. Non-full facepiece respirators shall be designed to accommodate protective eyewear, including, but not limited to, corrective eyewear, safety glassed, and gas-tight goggles.

The WFF-APR canister/cartridge label is color-coded with black font, and lists the type of chemical and particulate hazards against which it is rated.


Operating Considerations: Worn as directed by the authority having jurisdiction, and with protective clothing and equipment certified as compliant to NFPA 1977 Standard on Protective Clothing and Equipment for Wildland Fire Fighting.

NIOSH has listed the following limitations for Wildland Fire Fighting APR:

1. Not for use in atmospheres containing less than 19.5 percent oxygen.
2. Not for use in atmospheres immediately dangerous to life and 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/cartridge change schedules or observe End of Service Life Indicators to ensure that canisters/cartridges 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's Instructions for changing canisters/cartridges.
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's Instructions and/or maintenance manuals for information on use and maintenance of these respirators.
9. Consult manufacturer's User's 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. 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.
