In recent studies conducted by the National Institute of Standards and Technology (NIST), concerning findings have surfaced regarding the protective clothing—specifically turnout gear—worn by firefighters. These studies reveal that not only do these vital pieces of equipment contain per- and polyfluoroalkyl substances (PFAS), but also that their propensity to release these harmful chemicals increases under wear and tear.
PFAS, commonly referred to as “forever chemicals” due to their persistence in the environment, are linked to several adverse health effects, including cancer. This revelation is particularly concerning for firefighters, a group already at elevated risk for certain types of cancers compared to the general population.
What the Studies Found
The initial study identified over 20 types of PFAS in firefighter gear, highlighting variations in the amount and type of PFAS across different textiles and stress levels. These substances, widely used for their resistance to oil, water, and stains, are crucial for the gear’s effectiveness but pose significant risks.
A subsequent study subjected these textiles to conditions simulating real-world wear and tear, including abrasion, heat exposure, laundering, and weathering through UV radiation and high humidity. The findings were alarming; most notably, abrasion significantly increased PFAS concentrations across all tested textiles. This suggests that regular activities and exposure conditions can exacerbate the release of PFAS from the gear.
Implications for Firefighter Safety
While the NIST studies have laid a crucial foundation by mapping the presence of PFAS in turnout gear, they stop short of directly addressing the health implications for firefighters. This gap underscores the urgent need for further research by toxicologists, epidemiologists, and other health experts to assess the actual risks posed by PFAS exposure through such gear.
Given that most Americans, including firefighters, have detectable levels of PFAS in their blood—with firefighters showing higher levels—it’s crucial to explore and understand the full implications of these findings. Moreover, these studies also open the door to investigating real, long-used firefighter gear to gain insights into the broader environmental and health impacts.
Looking Forward: Safety Over Convenience
The research indicates potential pathways to reducing PFAS exposure without compromising the functionality of firefighter gear. This could involve exploring alternative materials that meet existing safety standards or adjusting the formulations used by different manufacturers to find safer combinations.
John Kucklick, a NIST chemist and co-author of the studies, posits that while using PFAS in turnout gear poses risks, it is crucial to balance these against the myriad hazards firefighters already face. This data empowers stakeholders to make more informed decisions about the materials used in manufacturing firefighter gear.
Conclusion
As we move forward, it is paramount for continuous research and dialogue among scientists, manufacturers, and firefighting communities to address these concerns. The goal is clear: to ensure the safety of those who risk their lives for us every day, without exposing them to additional, preventable hazards. This effort will require innovation, regulation, and perhaps most importantly, a commitment to prioritizing the health and safety of our firefighters above all else.
