NFPA 220 fire resistive ratings for type III construction indicate which construction type?

NFPA 220 fire resistive ratings for type III construction indicate which construction type?

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

Answer: (B)

NFPA 220 ties fire-resistance ratings to specific construction types, using the ratings of wall, floor, and roof assemblies to identify what type of construction a building uses. Type III is the ordinary construction category, characterized by exterior walls built with noncombustible materials and interior structural elements that can be wood. The fire-resistance ratings you see for a Type III building reflect these assemblies and confirm the building’s classification as Type III. In other words, the given fire-resistance ratings indicate ordinary construction.
