Church steeples, water tanks, chimneys, and false facades that extend above the structure must be viewed as a potential collapse hazard.

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

Answer: (A)

Extending features above the main structure create a collapse hazard. When elements like church steeples, water tanks, chimneys, or false facades project above the roofline, they can be unsupported or only partially attached to the building. Under fire conditions or during structural stress, these parts can fail and shed or topple onto the structure or crew, posing a sudden collapse risk.

The other options don’t fit as well: a protrusion hazard refers to obstacles that intrude into spaces where people move, an elevation hazard relates to working at height and fall risks, and an overhang hazard describes cantilevered parts that extend outward but aren’t inherently about anything rising above the structural envelope and failing.
