Fire resistive construction is characterized by exterior walls, floors, and roof made of what?

• A. Steel or other fire-resistive materials
• B. Wood
• C. Brick
• D. Glass

Answer: (A)

Fire-resistive construction relies on materials that resist ignition and maintain structural strength during a fire. In this approach, the exterior walls, floors, and roof are built from steel or other fire-resistive materials, often with protective coatings or encasements to achieve a higher fire rating. Steel is noncombustible and, when properly protected, retains its strength longer under heat, helping prevent collapse and slow the spread of fire. This is why the best choice is steel or other fire-resistive materials. Wood would burn and fail quickly; brick and glass do not fit the typical fire-resistive framing for these structural elements in this context.
