Following a ProPublica article revealing that the U.S. Forest Service had for years issued clothing to wildland firefighters that it knew contained potentially dangerous “forever chemicals,” the agency has stopped distributing those garments. It also says that it will instruct its equipment manufacturers to avoid using PFAS in the future.
This month, ProPublica reported that until at least 2023 one of the Forest Service’s suppliers, TenCate, used finishing products made with a PFAS compound on a Kevlar-blend pant fabric. According to emails from the supplier, the finishes were used to repel gasoline and water. Despite knowing about the use of PFAS, officials with the Forest Service had not previously informed wildland firefighters about it.
Per- and polyfluoroalkyl substances, or PFAS, have long been used in protective gear to repel substances like fuels. But many municipal fire departments have moved away from the chemicals as researchers revealed more about health risks associated with them. Firefighters in multiple states have filed class-action lawsuits against manufacturers alleging they were harmed by PFAS in the gear they wore. Research specific to wildland firefighters has lagged, and wildland firefighting agencies have been slower to publicly address the issue.
On Feb. 11, one day after ProPublica published its article, a Forest Service cache manager — an official who oversees a gear repository — wrote in an email that he asked colleagues to distribute widely, “I received notice from the Washington Office Cache Management staff late last night that we are to place a hold on issuing” the pants. But the agency didn’t immediately clarify further. A wildland firefighter who spoke on the condition of anonymity to protect their employment said last week that incident management teams had been asking the agency for advice about the pants. “As of right now, our logistics folks haven’t gotten any guidance at all from higher-ups,” the firefighter said.
On Friday, the Forest Service issued a statement to ProPublica: “PFAS in protective gear is a complex, industry-wide issue and any suggestion that the agency has sought to obscure information does not reflect the extensive work to expand testing and improve long-term occupational health protections for firefighters. Firefighter pants manufactured with PFAS water repellent fabric treatments have been removed from available stock in the National Interagency Support Caches.”
TenCate has not responded to repeated inquiries, but in an email reviewed by ProPublica, it told the Forest Service that a PFAS-free finish was available in January 2023. On Friday, the Forest Service sent an email to its staff saying that its supplier had switched to a PFAS-free finish that year. In the same email, the Forest Service wrote that anyone with the older pants “should discontinue use and replace” them. The agency also said that it was updating its requirements “to specify that fabric treatments and fabrics will not contain PFAS.”
Fire departments typically adhere to safety standards set by the National Fire Protection Association, a nonprofit that gathers input from expert committees including firefighters and representatives from companies that supply them with equipment. While the association is not a certifying body, its standards are used by government agencies including the Forest Service. Last year, an NFPA technical committee updated its standards for municipal firefighters to restrict levels of certain PFAS chemicals in protective gear. But the organization has not yet made a parallel update to its standard for wildland firefighters.
Rick Swan, an NFPA committee member, said the lag reflects a long and deliberative process for developing standards, but he added that a restriction on PFAS chemicals in wildland gear is all but inevitable. “I think it’s a no-brainer,” Swan said. In an email, a spokesperson for the NFPA wrote that the committee overseeing the wildland firefighting standard “will likely consider this issue again.”
Experts can’t say for certain what risks PFAS in gear pose to the health of wildland firefighters and agree more research is needed. Jeff Burgess, a professor and researcher at the University of Arizona who is leading a series of long-term studies of firefighter health, said smoke inhalation and the accumulation of soot on gear are primary ways wildland firefighters encounter carcinogens. Understanding of wildland firefighters’ exposures to PFAS has lagged behind understanding of exposure in municipal fire departments. Historically, researchers have had less access to wildland crews, and in recent years they have focused on studying risks related to smoke.
