Which hazard does the collapse zone rule primarily address?

• A. Falling debris
• B. Heat transfer
• C. Vibration
• D. Noise

Answer: (A)

The collapse zone rule is about preventing injury from material that can fall when a structure fails. When a building or part of it collapses, pieces of walls, floors, and roofs can break loose and travel outward and downward. The rule defines a collapse zone—the area where debris is likely to go during a collapse—so workers and equipment stay out of that space. This is why the hazard addressed is falling debris. Heat transfer, vibration, and noise are not the primary concerns of this rule; heat transfer relates to fire or heat exposure, vibration to ground or equipment movement, and noise to sound from activity, not the direct risk from collapsing material.
