Fire Prevention and Investigation - As enacted, creates the rescue squad grant program to provide annual grants to rescue squads for the purchase of firefighting equipment and training; directs the commissioner of commerce and insurance to evaluate grant requests and select grant award recipients each year. - Amends TCA Title 68, Chapter 102.

SB 1865 creates two annual grant programs for Tennessee fire and rescue organizations: a "rescue squad grant program" and a "volunteer firefighter equipment and training grant program." It provides funds specifically for purchasing firefighting equipment (excluding vehicles) and training, directly benefiting recognized rescue squads (municipal, county, or nonprofit emergency response groups) and volunteer fire departments. The commissioner of commerce and insurance will evaluate applications and award grants each year, aiming to spend all allocated funds annually without returning unused money to the general budget. The bill amends Tennessee law to establish these programs, effective July 1, 2026.
