Which construction type is described as Noncombustible (Industrial)?

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

Answer: (B)

Noncombustible construction focuses on using materials that don’t contribute fuel to a fire for the main structural elements. In industrial settings, this approach is captured by the construction type that relies on noncombustible materials like concrete and steel for the frame and major components. That’s why this category is described as Noncombustible (Industrial): the building’s structure is built from noncombustible materials.

This contrasts with other types: one is fire-resistive and uses rated assemblies to slow fire spread, another uses exterior noncombustible walls with combustible interior elements, and the last uses heavy timber for the structural frame. The industrial noncombustible option is the one that emphasizes noncombustible materials for the primary structure, which is why it corresponds to that label.
