What phrase is typically used to indicate that the primary search has been completed?

The phrase "Primary is all clear" is used to indicate that the primary search has been completed, signifying that all areas have been thoroughly searched for victims or fire threats. This phrase ensures that all team members are aware that the initial search operation has concluded, and any necessary rescue operations can begin or be confirmed as unnecessary.

Effective communication during firefighting operations is crucial, particularly in high-stress environments. Using standardized phrases enhances safety and efficiency, ensuring that all firefighters are on the same page regarding the status of the search and the structure's conditions.

In contrast, the other options do not reflect standard terminology used in firefighting operations. "Mitigation complete" usually pertains to the completion of control measures for hazards or fire, rather than the search phase. "Scan done over" is not recognized as a standard phrase in primary search operations, and "Pan search complete" may imply a specific technique rather than indicating that the primary search has been finalized. Thus, "Primary is all clear" stands out as the correct and recognized phrase.
