For the first time, federal firefighters are being encouraged to wear respirators to safeguard themselves from the harmful effects of smoke during wildland firefighting operations.

The U.S. Forest Service announced on Wednesday that firefighters are now permitted to use N95 respirators on fire scenes. This marks a significant policy shift, as protective gear had not been authorized for decades despite evidence highlighting the health risks linked to wildfire smoke.

“This change has been a long time coming,” stated George Broyles, a veteran USFS firefighter who has researched wildfire exposure risks. “It’s undeniable that first responders worldwide face increased risks of cancer and heart disease.”

For Broyles, this policy amendment signifies a long-overdue acknowledgment from the Forest Service of the toxic nature of wildfire smoke, prompting the agency to seek measures that mitigate risks for its personnel.

The Forest Service has historically been slow to address the health impacts of wildfire smoke and to implement necessary protections for workers in challenging firefighting environments.

Inhalation of wildfire smoke exposes individuals to volatile gases and fine particulate matter, which can infiltrate the lungs and enter the bloodstream. Such exposure is linked to respiratory issues, lung cancer, and various chronic diseases, as well as adverse pregnancy outcomes across diverse U.S. demographics. Studies indicate that wildland firefighters experience heightened risks for lung cancer and cardiovascular conditions.

The Forest Service also revealed plans to initiate a cleanup program aimed at minimizing firefighters’ skin exposure to toxins in soot and ash. Personnel will be compensated for time spent washing uniforms, cleaning vehicles, and showering post-fire operations.

The agency clarified that this updated policy serves as a temporary step towards establishing a more robust protective program that aligns with Occupational Safety and Health Administration standards.

“We’re committed to developing a comprehensive respiratory protection program without delay. We believe N95 respirators can be effectively utilized to offer protection, while allowing for removal if individuals overheat,” commented Evan Birx, a U.S. Forest Service spokesperson. “While use is not mandatory, we strongly encourage it.”

The Forest Service stated that fire managers and firefighters intending to use respirators will be required to undergo a training program.

As wildfires escalate in frequency and severity, researchers are racing to comprehend the long-term consequences of smoke exposure. Wildland firefighters represent a demographic at high risk for chronic smoke-related ailments.

A 2019 survey indicated that, depending on their career duration and exposure days, wildland firefighters are estimated to face an 8% to 43% increased risk of lung cancer and a 16% to 30% elevated risk of cardiovascular issues. Further studies reveal that wildland firefighters are more likely to develop hypertension and arrhythmia.

“Access to N95s, decontamination protocols, and relevant training can significantly reduce exposure to harmful smoke and toxins,” stated Steve Gutierrez, union representative for the American Federation of Federal Employees. “It’s vital to build upon this momentum with a long-term respiratory protection strategy, cancer screenings, early disease detection, and improved facilities like washing machines for decontamination.”

While N95 masks offer some level of protection, they are not a panacea. Their design can cause discomfort and may increase the effort required for breathing during intense physical activity. Moreover, while they prevent particulates from entering the body, they do not guard against carbon monoxide, formaldehyde, and other harmful gases emitted from fires.

According to Forest Service guidelines, these masks should not be used in steep terrains or environments where fire conditions are rapidly changing or where direct flame contact is possible.

“Currently, there isn’t a one-size-fits-all solution,” remarked Reba Duncan, president of Grassroots Wildland Firefighters, a nonprofit advocacy organization comprising current and former federal wildland firefighters. She characterized N95s as merely “an additional temporary measure.”

Nonetheless, developing a comprehensive ventilatory system in line with OSHA regulations could require “many years” to finalize, Broyles cautioned.

Both he and Gutierrez noted that many firefighters might opt not to wear N95 respirators.

“I believe it’s going to be a culture-changing process,” Gutierrez added.

This summer may be particularly challenging for wildland firefighters. As per the National Interagency Fire Center (NIFC) statistics, over 34,000 wildfires have ignited, scorching at least 2.7 million acres in 2023; both figures exceed the 10-year averages.

Numerous western states, including Utah and Colorado, have witnessed record spring snowfall yet are currently grappling with significant drought and heightened fire risks. Concurrently, a strong El Niño phenomenon is unfolding, leading to anticipated increases in global temperatures.

NIFC’s prediction map indicates a potential to exceed average fire activity in various areas throughout this summer, with no regions displaying “below normal” forecasts.
