NFPA 220 lists fire-resistive ratings for Type III construction as which values?

• A. 221 and 200
• B. 222 and 111
• C. 221 and 111
• D. 210 and 190

Answer: (A)

NFPA 220 encodes fire-resistance ratings for Type III construction with a pattern that shows ratings for wall assemblies first (exterior bearing wall, interior bearing wall, interior nonbearing partition) and then for floor/ceiling assemblies. For Type III, exterior bearing walls get a 2-hour rating, interior bearing walls also get 2 hours, and interior nonbearing partitions get 1 hour, which gives the wall triplet 2-2-1. The floor/ceiling assemblies are rated as 2 hours for the floor/ceiling portion, with zeros for other related components in this context, giving 2-0-0. Putting those together yields 221 and 200, matching how NFPA 220 presents the data. The other options would imply different ratings for these elements that don’t align with the Type III table in NFPA 220.
