![]() ![]() Wildland Firefighter Respirator Fact Sheet. ![]() Learn More About Wildland Fire Respirators ![]() The Wildland Fire Respirator was most recently operationally field-tested by firefighters under high heat exercise conditions in the summer of 2023 in California. S&T is working to develop a respiratory protection system capable of removing airborne hazards present in the wildland firefighting operating environment. The Occupational Safety and Health Administration’s permissible exposure limit for CO is only 35 ppm for an eight-hour exposure and 150 ppm for a 15-minute short-term exposure. ![]() Peak exposures of CO as high as 179 parts per million (ppm) have been measured in some controlled burns. As a result, wildland firefighters potentially inhale dangerous byproducts of thermal decomposition and combustion, including carbon monoxide (CO), acrolein, polycyclic aromatic hydrocarbons, aldehydes and ketones, and acid gases. Bandanas cannot protect against the extremely fine (and most hazardous) particles present in smoke aerosols from the wildland fire environment. Wildland firefighters need a small, lightweight device that is easy to put on and take off and can be relied upon to last during a lengthy response.įor many wildland firefighters, a cotton bandana is their standard and the resulting respiratory protection is woefully insufficient. But unlike structural firefighters, wildland firefighters are unable to use standard self-contained breathing apparatus respirator systems, which are heavy, bulky, and limited to a short supply of air. Wildland firefighters are exposed to many of the same naturally occurring respiratory hazards as structural firefighters.
