How should the search team approach a secondary search?

The correct approach for a secondary search is to proceed with caution, especially when the fire is under control. This is crucial for ensuring the safety of the search team and any potential victims who may be in the building. When the fire is under control, conditions within the structure are more stable, allowing firefighters to conduct searches more effectively.

Approaching the search with caution means being aware of possible hazards, such as structural instability or residual heat and smoke, which may still pose risks. This careful approach also allows the team to communicate effectively and coordinate their actions, ensuring thoroughness while prioritizing personal safety.

The other options suggest either inadequate preparation or an unsafe demeanor while conducting a secondary search. Relying solely on full PPE and SCBA without considering the fire's status may not be the most effective, as it could hinder mobility and visibility. Similarly, not using any equipment would leave the search team vulnerable, and rushing through a search could lead to oversight of areas that might contain victims or important evidence. Therefore, conducting a secondary search with a focus on safety and caution after the fire has been controlled is the most appropriate strategy.
