What action is recommended if you observe signs of imminent structural collapse?

• A. Withdraw personnel to a safe distance; switch to a defensive approach; notify IC and establish collapse zone.
• B. Enter quickly to perform rapid search.
• C. Continue as planned.
• D. Call for extra lighting.

Answer: (A)

When you sense signs that a structure could fail, the priority is to protect responders by shifting to a defensive stance and keeping people out of the danger zone. Withdraw personnel to a safe distance and stop interior operations; focus on incident stabilization from outside and protecting exposures. Notify the incident commander so they can establish a collapse zone and a safe perimeter, ensuring no one enters the area where debris could fall. This approach reduces risk to crews when the building may give way, which is why it’s the best course of action. Entering quickly for a rapid search, continuing as planned, or addressing unrelated needs like lighting don’t address the immediate collapse hazard and place people at unnecessary risk.
