Which NFPA classification set includes Building types I through V?

Which NFPA classification set includes Building types I through V?

• A. II-V
• B. I-VI
• C. I-V
• D. I-II-III

Answer: (C)

NFPA construction classifications describe five broad building types used to gauge fire resistance and materials. The set that includes all five is I through V, which NFPA 220 uses to categorize construction. Type I is the most fire-resistive, Type II is noncombustible, Type III is ordinary, Type IV is heavy timber, and Type V is wood frame. There isn’t a standard Type VI in this classification, so a set that includes VI isn’t valid. Therefore, listing I through V is the correct choice. Sets that omit Type I, add an extra type, or miss one or more of the five categories don’t match how NFPA classifies construction.
