How can a rescuer assess the risk of further collapse?

A rescuer can effectively assess the risk of further collapse by continually monitoring structural integrity and conditions during rescue efforts. This ongoing assessment is crucial because the structure may continue to settle or shift as work progresses, and new hazards can emerge at any moment. By keeping a close watch on existing damage, environmental factors, and the overall stability of the structure, rescuers can identify signs of potential failure, such as cracks, shifting materials, or unusual sounds, and adjust their strategies accordingly.

This proactive approach not only ensures the safety of the rescuers but also enables them to take timely actions to protect any trapped victims. Relying on guesswork or previous experiences is insufficient because past incidents may not reflect the current situation, and ignoring the condition of the structure neglects the immediate risks present in a dynamic and unpredictable environment.
