Wipe Test Can Help Protect Firefighters From Cancer-Linked Chemicals

This makes PFAS removal and breakdown very difficult, researchers explained in background notes.PFAS compounds have been used in consumer products since the 1940s, including fire extinguishing foam, nonstick cookware, food wrappers, stain-resistant furniture and waterproof clothing.For the new study, researchers swabbed high-contact areas of 12 sets of turnout gear and masks with damp polypropylene wipes, then analyzed the wipes.Every gear set tested carried PFAS, even inside the breathing masks where firefighters expect clean air, researchers found.Even these trace amounts left on equipment could add up to meaningful exposure across a firefighter’s career, with the chemicals soaking into their skin or inhaled into their lungs, the research team estimated.“We want PFAS to stay off skin, off gear and out of stations,” researcher Natasha Schaefer Solle, a deputy director and investigator at the Firefighter Cancer Initiative, said in a news release. “A quick wipe test helps crews make smarter choices — before invisible hazards become lifelong burdens.”Fire stations could employ this test to judge when to clean gear and which items might need deep decontamination before the next call, researchers said.And because the method doesn’t damage textiles, officials can routinely use the wipes to test turnout gear after multi-alarm fires or incidents where they had to use lots of PFAS-loaded foam against a fire, researchers said.“Think of it as turning on a blacklight in a dark room,” researcher Dr. Alberto Caban-Martinez, a deputy director and investigator at the Firefighter Cancer Initiative, said in a news release. “Suddenly, you see what’s been hiding all along.”More informationThe Environmental Working Group has more on PFAS chemicals.SOURCE: University of Miami, news release, Dec. 29, 2025 .What This Means For YouA new test can protect firefighters against PFAS exposure from their own protective gear..Sign up for our weekly HealthDay newsletter
