NFPA 220 fire resistive ratings for Type II construction are listed as which sequence?

• A. 222 111 000
• B. 221 200 000
• C. 222 222 000
• D. 111 111 000

Answer: (A)

In NFPA 220, the fire-resistive ratings for Type II construction are given in a three-part sequence that maps to the main structural elements: the frame members, the floor/ceiling assemblies, and the roof/ceiling elements. Each number shows the hours of fire resistance required for that element type. For Type II, the frame members are rated 2 hours, the floor/ceiling assemblies are rated 1 hour, and the roof or related components have no specific rating (0). That pattern is written as 222 111 000, which is why that option is the best choice. The other sequences would imply different ratings for these elements, which don’t align with Type II requirements.
