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.

HB 1489 would expand Tennessee's cancer presumption law for firefighters to include arson investigators. The bill amends state law to define "firefighter" as specifically covering full-time arson investigators employed by the Tennessee Bureau of Investigation or county sheriff's departments. This change means these investigators would automatically qualify for disability benefits if they develop cancer, as their job-related exposure would be presumed to cause it - similar to current firefighter protections. The bill directly affects arson investigators working in these specific state and local law enforcement roles.
