This bill mandates the Secretary of Defense to establish a program and fund, to be known as the "Military Firefighters Compensation Fund," within two years of enactment. The primary purpose of this fund is to provide timely, uniform, and adequate compensation to current and former military firefighters, and where applicable, their survivors, who have incurred illnesses or death due to exposure to per- and polyfluoroalkyl substances (PFAS) during their service for the Department of Defense or its contractors. For the purposes of this compensation program, current and former military firefighters are presumed to have been exposed to PFAS if they were employed at a military installation, National Guard facility, or formerly used defense site during a period when PFAS would have been present. In addition to compensation for disability or death, the program will furnish medical benefits, including necessary services, appliances, supplies, and related transportation expenses, as prescribed by a qualified physician. Payments for deceased firefighters follow a specific hierarchy, prioritizing surviving spouses, then children, parents, grandchildren, and grandparents, with special provisions for minor children not recognized by a surviving spouse. Benefits will commence from the date the claim is submitted.
