Chemical Concerns in Firefighter Gear: PFAS Replacement Raises New Questions
Table of Contents
firefighters rely on their protective gear – frequently enough called turnout gear – to keep them safe in hazardous environments. Though, a growing body of research indicates that the very materials designed to protect them may contain chemicals with potential health risks. While initial concerns focused on PFAS (per- adn polyfluoroalkyl substances), a recent study reveals that phasing out these chemicals has led to increased use of brominated flame retardants (BFRs), raising new questions about firefighter safety.
the PFAS Problem
For years, PFAS have been used in turnout gear to provide water and oil resistance U.S. Environmental Protection Agency. While effective,these chemicals have been linked to a range of health issues,including cancer, thyroid disease, and developmental problems. The national Fire Protection Association (NFPA) continues to monitor research regarding PFAS and their potential impact on firefighter health NFPA Journal.
The Rise of bfrs
As manufacturers began phasing out PFAS in response to health concerns, researchers from Duke University, led by environmental chemist Heather Stapleton, investigated whether option chemicals were being used. Their study, published in Environmental Science & Technology Letters DOI: 10.1021/acs.estlett.5c01153, tested turnout gear manufactured between 2013 and 2024.
The findings were concerning: While newer, PFAS-free gear showed considerably reduced levels of PFAS-likely due to environmental contamination-all gear samples tested contained BFRs.notably,the newer gear designed to be PFAS-free actually contained higher levels of BFRs.
Specifically, decabromodiphenyl ethane (DBDPE) was the moast prevalent BFR detected. DBDPE has been linked to thyroid disruption, according to the National Institute of Environmental Health Sciences (NIEHS).
What are brominated Flame Retardants?
Brominated flame retardants are a class of chemicals added to materials to prevent or slow the spread of fire.While they can improve fire safety, some BFRs have been associated with adverse health effects, including neurological and developmental problems, and endocrine disruption.
Implications for Firefighters
The study underscores the need for greater transparency from gear manufacturers regarding the chemicals used in turnout gear. Fire departments and firefighters deserve comprehensive information to make informed decisions about their personal protective equipment.
Moving Forward
Stapleton and her team emphasize the urgency of further research into the health effects of BFRs and other alternative chemicals used in firefighter gear. This research should include long-term studies to assess the cumulative exposure and health outcomes for firefighters. Continued investigation into safer alternatives and improved material standards are crucial to protecting those who protect us.
