Who typically establishes command at an incident?

The first arriving officer typically establishes command at an incident because they are in the best position to assess the situation directly. Upon arrival, this officer can evaluate the scene, identify any immediate threats, and determine the necessary resources required to manage the incident effectively. Establishing command early is crucial for ensuring that all responders can work collaboratively and follow a unified chain of command, which enhances the efficiency and safety of the incident response.

While the senior officer present may hold a higher rank and have extensive experience, their arrival might not coincide with the first assessment of the situation. The firefighter with the most experience can provide valuable insights but might not have the situational awareness that the first officer on the scene possesses. Similarly, the dispatcher plays a critical role in communication and coordination but does not physically assess the incident and establish on-the-ground command like the first arriving officer does.
