Fire Prevention and Investigation - As enacted, requires certification from the peace officer standards and training commission and certain other criteria to be met in order for the commissioner of commerce and insurance, the commissioner's deputies, a municipal fire investigator, or a salaried county fire investigator to exercise police powers, including the power to arrest, relative to cases of arson or suspected arson. - Amends TCA Title 5; Title 6; Title 38 and Title 68.

SB 2005 requires certain fire investigators in Tennessee to hold a Peace Officer Standards and Training (POST) certification to exercise police powers - such as making arrests - in arson or suspected arson cases. This applies to the Commissioner of Commerce and Insurance and their deputies, municipal fire investigators, and salaried county fire investigators. Investigators may still conduct routine fire origin investigations without certification but must have it when using police authority. The requirement takes effect January 1, 2027, with POST issuing certifications after meeting police officer qualifications and completing annual training.
