Firefighters - As enacted, expands the applicability of the presumption that a firefighter's cancer was caused by the firefighter's employment to include arson investigators. - Amends TCA Title 7; Title 8; Title 50 and Title 56.

SB 1616 expands Tennessee's disability benefits for firefighters by including arson investigators in the definition of "firefighter" under state law. Specifically, it amends Tennessee Code to clarify that arson investigators employed by the Tennessee Bureau of Investigation (TBI) or county sheriff's departments are now covered by the presumption that cancer diagnosed during their service was caused by their job. This change directly affects these arson investigators, allowing them to qualify for disability benefits under the same provisions previously available only to traditional firefighters. The bill modifies existing statutes in Titles 7, 8, 50, and 56 to implement this expanded eligibility.
