Judge says 3M, DuPont, and Honeywell must face Connecticut firefighters' PFAS claims
A U.S. judge ruled that 3M, DuPont, Honeywell, and others must face claims from Connecticut firefighters over PFAS exposure in protective gear. The lawsuit alleges the gear, containing 3M's Scotchlite and DuPont's Kevlar, increased cancer risks. The judge allowed the case to proceed, permitting damages and medical monitoring claims. The companies argue the gear served its protective function. PFAS makers face broader scrutiny, with prior settlements totaling over $11 billion.
