Which action should be taken to manage the collapse zone when collapse is suspected?

• A. Move equipment closer to the structure
• B. Evacuate everyone to the main entrance
• C. Establish and clear the collapse zone
• D. Increase interior reconnaissance

Answer: (C)

When a collapse is suspected, the priority is to create a safe buffer around the structure by establishing and clearly clearing a collapse zone. This zone is the area where debris is likely to travel if the structure fails, so you set up a defined perimeter and keep all personnel and unnecessary equipment out of it. Controlling this space allows responders to work from a safe distance, gives time to assess stability, and reduces the chance of injuries from falling or debris impact. Moving equipment closer or evacuating to a single entrance doesn’t guarantee safety, and increasing interior reconnaissance without first securing the exterior hazard unnecessarily exposes people to risk. Establishing the collapse zone directly addresses the hazard and supports safer operations.
