Who has the legal responsibility to determine the causes of fires in most jurisdictions?

• A. Incident Commander
• B. Fire Chief
• C. Public Information Officer
• D. Facility Supervisor

Answer: (B)

The person with final legal responsibility for determining why a fire occurred is the Fire Chief. The Fire Chief is the top administrator of the department and is accountable to the city or district for all departmental actions, including ensuring that a proper fire investigation is conducted, that the origin and cause are determined, and that the findings are documented and reported. While trained fire investigators or fire marshals typically perform the technical determination of origin and cause, their work is overseen and authorized by the Fire Chief, and the Chief often signs off on the conclusions in many jurisdictions. The Incident Commander focuses on managing operations at the scene, not on legal determinations of cause; the Public Information Officer handles communications; and a Facility Supervisor isn’t part of the official investigative chain.
