Fire Prevention and Investigation - As enacted, changes present law concerning the frequency of fire drills in educational occupancies. - Amends TCA Title 68, Chapter 102.

HB 453 requires Tennessee schools to conduct full evacuation fire drills at least once every 30 school days (including two drills in the first 30 days of the school year) and hold four annual fire safety educational announcements developed by school districts. It also mandates fire drills every two months in institutional settings like group homes, with schools required to maintain detailed records of all drills for state fire marshal review. The law supersedes conflicting local regulations and applies to educational and institutional occupancies as defined in the bill. It became effective in May 2025 after being enacted as Public Chapter 315.
