This bill would expand federal workers' compensation benefits for certain Bureau of Alcohol, Tobacco, Firearms and Explosives employees by classifying them as "fire protection workers." Specifically, it would include Certified Fire Investigators and members of the National Response Team at the ATF in the definition of employees eligible for compensation for illnesses and diseases that develop from their work in fire protection activities. These employees would become eligible for federal compensation benefits similar to those provided to firefighters and other federal fire protection personnel for work-related health conditions. The change would apply to all compensation claims filed on or after the date the bill becomes law, with no specific funding amount mentioned in the legislation. This amendment primarily affects ATF personnel who investigate fires and respond to fire-related incidents as part of their job duties.
