What is the correct protocol if an Incident Commander suspects arson at a fire scene?

When an Incident Commander suspects arson at a fire scene, the correct protocol involves promptly notifying the fire marshal. This is essential because the fire marshal has the expertise and authority to investigate suspected arson cases. By involving the fire marshal early, an investigation can begin in a timely manner, which is crucial for preserving potential evidence and collecting information on the scene that may indicate foul play.

Additionally, notifying the fire marshal ensures that appropriate procedures are followed to secure the scene and safeguard any evidence that could be crucial for the investigation. The fire marshal's involvement is important for coordinating with law enforcement and ensuring that all necessary fire investigation protocols are adhered to.

In contrast, actions such as contacting law enforcement first, waiting for evidence to be collected, or promoting public safety awareness do not address the immediate need for a specialized investigation into the suspected arson. Inadequate communication or delays in notifying the fire marshal may hinder the investigation and compromise the integrity of the evidence.
