Which hazard is described as a potential collapse hazard due to features extending above a structure?

• A. Collapse hazard
• B. Protrusion hazard
• C. Elevation hazard
• D. Overhang hazard

Answer: (A)

Collapse hazards cover the risk that a structure or its supporting elements could fail, including parts that extend above the main body of the building. When features project beyond the roofline or top of the structure, they can alter the load path or become unstable as heat weakens connections, increasing the chance of sudden collapse. That’s why describing it as a potential collapse hazard makes sense: these elevated or extending features contribute to the overall risk of structural failure.

Protrusion hazards describe objects protruding into working spaces and posing contact or entanglement risks, not primarily the stability of the building. Elevation hazards involve working at height and fall risks, while overhang hazards concern parts extending outward from the edge that could drop, but not necessarily the structure’s collapse.
