What term describes the area around a building kept clear due to potential collapse?

• A. Evacuation zone
• B. Safety perimeter
• C. Collapse zone
• D. Buffer area

Answer: (C)

The essential idea is identifying the area around a building that must stay clear because the structure could fail and debris could reach that space. In safety practice, the collapse zone is defined as the region into which the building or any of its parts could fall if it fails. This zone is determined by factors like the building’s height, construction, and condition, and it’s kept free of people and equipment to protect lives during dangerous conditions such as demolition or instability. The other terms aren’t as precise for describing this specific hazard: an evacuation zone is about moving people away due to danger like fire or smoke, not the potential reach of falling debris; a safety perimeter is a broader boundary intended to protect against multiple hazards and isn’t specific to collapse debris reach; a buffer area is a general extra clearance term without naming the hazard of collapse. So the term that best fits is collapse zone.
