A fire load rating of 11-15 in pounds per square inch is considered:

• A. Mild
• B. Moderately Severe
• C. Severe
• D. Very Severe

Answer: (B)

Fire load rating expresses how much fuel and how much energy a area could release in a fire. On this scale, 11–15 pounds per square inch falls in the middle tier, which is described as Moderately Severe. It indicates a substantial amount of fuel and a high potential heat release, but not at the extreme end of the hazard spectrum. This level guides fire protection decisions to be stronger than what would be used for a mild rating, while not requiring the maximum controls reserved for severe or very severe scenarios.
