Wear and Tear May Cause Firefighter Gear to Release More ‘Forever Chemicals’

"Last year, a study by the National Institute of Standards and Technology (NIST) showed that the textiles used in protective clothing worn by firefighters often contain per- and polyfluoroalkyl substances, or PFAS, a class of chemicals that has been linked to an increased risk of cancer and other health effects.

Now, a follow-up study from NIST shows that the textiles used in that protective clothing, called turnout gear, tend to release more PFAS when they are subject to wear and tear. Taken together, the two studies identified the PFAS compounds present in selected turnout gear textiles, how much of each was present, and whether simulated wear and tear increased the amount of PFAS that the textiles released.

“The firefighter community has raised concerns about PFAS in turnout gear, but before these studies, there was very little data that address those concerns,” said NIST chemist and study co-author Rick Davis. “Based on these studies we can confidently say that more than 20 types of PFAS might be present in firefighter gear and that the amount and type of PFAS vary depending on the type of textile used and the amount of stress it has been subjected to.”
