Who must the Incident Commander notify if a fire is declared suspicious after the scene has been left?

When a fire is declared suspicious after the scene has been left, it is crucial for the Incident Commander to notify both the Dispatcher and the Bureau of Fire Investigation. This notification is essential because the Bureau of Fire Investigation is responsible for examining the circumstances surrounding suspicious fires and determining their origin and cause. Involving them ensures that proper investigative protocols are followed, safeguarding evidence and enabling thorough examination.

Notifying the Dispatcher is also a vital step, as they play a key role in coordinating resources and communication among all responding units. They can ensure that the appropriate investigative personnel are dispatched to the scene and that all necessary agencies are informed of the situation, which aids in subsequent operations related to fire investigation.

In contrast, the Fire Chief, Safety Officer, and Operations Officer, while valuable in their respective roles, are not specifically responsible for the investigative actions required in cases of suspicious fires after the scene has been vacated. Thus, the correct choice emphasizes the importance of connecting the Incident Commander to the relevant entities that handle the complexities of suspicious fire investigations.
