Who typically conducts the initial investigation of a fire at a scene?

The fire officer in command is typically responsible for conducting the initial investigation of a fire at the scene. This individual holds a leadership position on the incident scene and is tasked with assessing the situation, determining the extent of the fire, and establishing command. The officer in command gathers critical information about the fire's origin, potential hazards, and the presence of victims, all of which are essential to effectively coordinating response efforts and ensuring safety.

While the first arriving unit plays a crucial role in initial fire suppression and rescue efforts, it is ultimately the fire officer in command who oversees operations and strategic decisions, which includes leading the initial investigation. This officer is trained not only in firefighting tactics but also in fire cause determination, making them well-equipped to start evaluating the circumstances surrounding the fire.

In contrast, the safety officer focuses on the safety of all personnel at the scene, ensuring that operations are conducted safely, rather than directly investigating the fire itself. The fire chief, while having oversight and administrative responsibilities, may not be directly involved at the scene initially unless they are the officer in command or designated to do so.
