Fire Investigations

TBI's fire investigators respond to incidents involving fire across the state that are destructive to buildings and other properties as well as those that result in fatalities.  We work closely with local jurisdictions to determine cause, origin, and circumstances of fire. In conjunction with the Tennessee Department of Commerce and Insurance, TBI supports efforts to organize education and training programs within the state for local and federal agencies to further protect the safety of Tennesseans and their property.

Arson Hotline

The Arson Hotline (1-800-762-3017) is a phone line dedicated to receiving information about suspicious and incendiary fires. It is answered 24 hours a day and you may remain anonymous when providing information. Cash awards, provided solely through the generous assistance of the Tennessee Advisory Committee on Arson (TACA), are offered for information leading to an arrest or conviction.

Support for the hotline is the result of an ongoing partnership between the TBI and TACA.
