Which partition rating is required between bunk rooms?

• A. 0 Hour
• B. 1 Hour
• C. Smoke
• D. 2 Hour

Answer: (C)

The design goal here is to limit the spread of smoke between sleeping spaces. Between bunk rooms, a smoke partition is required because it provides containment of smoke without imposing a full fire-resistance rating. This protects occupants by delaying smoke migration and allowing more time to evacuate. A 0-hour partition wouldn’t restrict smoke at all, and a higher fire-resistance-rated wall (1-hour or 2-hour) isn’t required for this separation; the standard isn’t about fire heat transfer but about limiting smoke movement. So the correct choice is a smoke partition.
