The Firefighter PFAS Injury Compensation Act of 2026 creates a federal compensation program for firefighters who have suffered health injuries from exposure to PFAS (per- and polyfluoroalkyl substances), which are chemicals found in firefighting foam and other products. Eligible firefighters who have served at least two years and developed a PFAS-related health condition can receive compensation ranging from $50,000 to $250,000, adjusted based on years of service and special circumstances, with payments coming from a dedicated PFAS Trust Fund. The program, administered by the Secretary of Health and Human Services, covers civilian, military, and volunteer firefighters as well as their heirs, with claims processed within 120 days with no burden of proof on applicants and the ability to appeal decisions to the Court of Federal Claims. Firefighters must submit claims within two years of when regulations become final, and an advisory panel will evaluate claims for unlisted health conditions. The bill is exempt from budget offset requirements, allowing it to proceed without requiring spending cuts or revenue increases elsewhere in the federal budget.
