Which construction type is described as high-rise buildings, not likely to collapse, with the primary hazard being flying glass?

• A. Type I
• B. Type II
• C. Type III
• D. Type IV

Answer: (A)

Understanding how construction type shapes fire behavior and the hazards it presents is key here. Type I construction is fire-resistive and built with noncombustible materials, designed to maintain structural integrity for a set period, which makes high-rise buildings less likely to collapse quickly in a fire. The trade-off is the potential for large glass façades to fail and send shards flying, creating a serious hazard for occupants and firefighters alike. Other construction types describe different materials and failure modes, but they don’t match the combination of strong, high-rise stability and the predominant flying-glass hazard that’s characteristic of Type I.
