The Fairness, Inclusion, Rehabilitation, and Expungement for Incarcerated Firefighters Act, or FIRE Act, aims to significantly improve the working conditions and post-incarceration opportunities for individuals engaged in firefighting while incarcerated. It amends the Occupational Safety and Health Act of 1970 (OSHA) to extend workplace safety and health protections to incarcerated firefighters in both state and federal correctional facilities. Furthermore, the bill modifies the Fair Labor Standards Act of 1938 (FLSA) to recognize incarcerated firefighters as "employees," ensuring they receive fair wages, while explicitly excluding the cost of board, lodging, or court-imposed fees from their pay. The legislation mandates annual reporting from correctional facilities on workplace safety conditions, injuries, and potential noncompliance with safety standards. To encourage state participation, the bill provides incentives and establishes a grant program, authorizing $100 million annually for fiscal years 2026 through 2031, to assist states in amending their occupational safety and health laws to cover incarcerated firefighters and enforce these new protections. States receiving certain federal grants would also be required to certify that they provide adequate safety protections for incarcerated firefighters. Beyond incarceration, the FIRE Act addresses reentry challenges by creating a new grant program under the Workforce Innovation and Opportunity Act. These grants will fund eligible entities to provide crucial job training, placement services, and mentoring to former incarcerated firefighters during their 180-day reentry period. A key provision of the bill allows eligible incarcerated firefighters, who have fulfilled their sentence requirements, to petition for the expungement of certain criminal offenses. This expungement would restore their legal status, remove disqualifications for lawful activities, and prevent the use of expunged convictions in future sentencing, though records would be retained non-publicly for specific law enforcement purposes with penalties for unauthorized disclosure.
