Secondary collapse is an example of which hazard category?

• A. Environmental hazards
• B. Physical hazards
• C. Both
• D. None

Answer: (B)

Hazard categories separate threats into physical hazards versus environmental hazards. Secondary collapse is about the danger from physical forces—falling or shifting rock and debris that can injure or trap people and damage equipment. That direct risk to people comes from actual physical harm, so it fits squarely as a physical hazard. It isn’t primarily about environmental conditions like weather, contamination, or ecological damage, which would make it an environmental hazard. It also isn’t none or both, since the essential danger is the physical threat posed by collapsing material.
