Secondary search should be:

The correct choice emphasizes the importance of having a separate search team conduct the secondary search. This approach is beneficial because it maximizes safety and effectiveness in a high-risk environment. After the primary search is completed, a different team can enter the area to look for victims or evidence of fire spread without the potential confusion or overlap that may arise if the same team conducts both searches.

Using a different team allows the initial responders to regroup, reassess, and provide updates on conditions within the incident, while the secondary team can focus on their task with a fresh perspective. Additionally, the conditions may change during a fire, and having a new team ensures that the initial efforts are backed by those who may have different experiences and situational awareness, which is particularly important in rapidly evolving incident scenarios.

This strategy enhances thoroughness in victim recovery and reduces the chances of overlooking areas or individuals during the search process. The availability of a dedicated team for the secondary search can also alleviate the mental and physical fatigue that may affect the original search team after the intense conditions they faced during the primary search.
