What communication should take place once primary search is completed?

Once the primary search is completed, the appropriate communication is to announce "All clear." This phrase signifies that the search teams have successfully checked all designated areas and have accounted for any potential victims or hazards. Declaring "All clear" is crucial for the safety of both the incident personnel and anyone potentially inside the structure. It informs command that the area is secure and that there are no remaining victims or individuals who could be at risk, allowing for further tactical decisions to be made regarding the incident, such as attacking the fire or conducting evacuations when necessary.

This communication helps establish an accurate situational awareness for firefighting and rescue operations, ensuring that responders are aware of the conditions within the structure and can act accordingly. Additionally, it allows the command team to prioritize actions based on the overall assessment of the incident scene.
