Which individual should be the first on scene to conduct the size-up of a collapsed structure?

The individual responsible for conducting the size-up of a collapsed structure should be the incident commander or designated rescue officer. This role is crucial because the incident commander is tasked with overseeing the entire rescue operation, ensuring both effective management and safety for all personnel involved.

The size-up process involves assessing the conditions of the scene, determining the scope of the collapse, identifying hazards, and evaluating resources needed for the rescue operation. The incident commander possesses the authority and responsibility to make critical decisions regarding the safety of the rescue teams and the victims. Their training typically includes a comprehensive understanding of structural integrity, hazards associated with collapsed structures, and effective rescue strategies.

Furthermore, relying on the incident commander or designated rescue officer ensures a coordinated approach. This professional will not only collect information, but also articulate a plan to address the situation efficiently while considering the safety of both rescuers and victims. Their leadership is vital for establishing communication among all team members and directing subsequent actions based on their observations during the size-up.
