What benchmark indicates the completion of the search/rescue tactical objective?

The benchmark indicating the completion of the search and rescue tactical objective is that the primary search has been declared "All Clear." This means that the designated team has thoroughly searched all areas of the building for potential victims and has confirmed that there are no people remaining inside who are in need of assistance. Declaring the primary search "All Clear" is crucial because it signifies that the immediate life safety threat has been addressed, allowing responders to shift focus to other tactical priorities such as fire control or property protection.

The completion of the search/rescue objective is paramount for ensuring the safety of all individuals involved and for structuring the response efforts efficiently. Only after confirming no persons are left in danger can rescuers proceed with other operations, ensuring the safety of both the victims and the responders themselves. The other options, while important in the overall incident management framework, do not specifically mark the completion of the search and rescue task as effectively as declaring the primary search "All Clear."
