When conducting a primary search during a fire, rescuers should:

Working in teams of two or more during a primary search in a fire situation enhances safety and effectiveness. This approach allows for better communication and coordination, reducing the risk of missing a victim or being overwhelmed by the conditions within the structure. Having a partner ensures that if one rescuer encounters a problem, the other can provide assistance or call for help. Moreover, two or more personnel can cover more ground and check different areas more thoroughly, which is crucial in a potentially chaotic and dangerous environment such as a fire.

The rationale behind this practice is grounded in firefighting and rescue protocols, which prioritize both the safety of the rescuers and the efficiency of the operation. Teamwork allows for sharing of situational awareness and resources, which is vital in conducting a comprehensive and rapid search.

Other strategies mentioned, like working alone or entering from multiple exits simultaneously, can complicate the search process and increase risks. Searching at night does not typically apply to the general guidance for primary search operations either. Overall, teamwork is a foundational principle in firefighting operations, enhancing both safety and effectiveness during the critical task of victim search and rescue.
