Which barrier is commonly used to separate crowds and protect the scene in a collapse operation?

• A. Chain-link fences
• B. Concrete barriers
• C. Jersey barriers
• D. Plastic barricades

Answer: (C)

Separating crowds from a collapse scene requires a barrier that is heavy, stable, and quickly deployable to create a clear, protected perimeter. Jersey barriers are exactly that: prefabricated concrete barriers with a curved face and top that provide a solid, continuous line. Their mass resists movement, they deter vehicle intrusion, and they can be arranged along the scene to shield responders, victims, and hazards from outreach or traffic. This makes them the reliable choice for crowd separation and scene protection in collapse operations.

Chain-link fences are easier to breach or climb, plastic barricades lack the mass to stop debris or vehicles, and plain concrete barriers are heavy and less versatile for quick setup and reconfiguration.
