Expands certain powers given to peace officers employed by the state fire marshal when certain exigent circumstances exist

HB 3535 expands the authority of certified state fire marshal investigators, who are now officially designated as peace officers. The bill allows these investigators to make arrests related to fire, explosion, or arson investigations without needing a local law enforcement agency's request when immediate threats to public safety exist. It also requires them to cooperate with local fire or police officials during such investigations. This directly affects the state fire marshal's office and local law enforcement agencies by clarifying and broadening investigative powers during urgent fire-related emergencies.
