When a more qualified person arrives on scene, which statement best describes what happens?

When a more qualified person arrives on the scene, the responsibility for managing the incident is formally transferred to them through a process known as the transfer of command.

As per the FEMA official material The new Incident Commander must assess the situation with the outgoing Incident Commander and obtain a briefing on the current status, including resources assigned, incident objectives, and strategies being implemented.” For example, during a wildfire, the Incident Commander ensures that firefighting units from different jurisdictions can work together seamlessly, maintaining clear lines of command and communication.

From the perspective of other personnel, the transfer of command is viewed as a critical component for maintaining operational efficiency and ensuring the safety of all involved.
