What is the minimum fire resistance rating required for a refuge area?

• A. 30 minutes
• B. 1 hour
• C. 2 hours
• D. 4 hours

Answer: (B)

Refuge areas are protected spaces designed to keep people safe from heat, flames, and smoke while they wait for rescue or a safe way to evacuate. The walls, floors, ceilings, and doors surrounding a refuge area must be fire-resistance-rated, and the minimum rating commonly required is one hour. This duration provides a reliable degree of protection during the early to middle stages of a fire and the time it takes for responders to reach the area or for occupants to move to safety. A shorter rating, like thirty minutes, wouldn’t offer enough time for protection, while higher ratings (two or more hours) are required only in specific high-risk or particular building configurations. So, one hour is the standard minimum.
