Reference

Fire Risk Score Model (based on NFPA 551 / FM Global methodology): Raw Score = Occupancy Factor * Construction Factor * Exposure Factor Protected Score = Raw Score * Sprinkler Factor * Detection Factor Occupancy: 1-5 (NFPA 13 hazard groups) Construction: 1-5 (IBC Types I-V) Sprinkler/Detection: 0.5-1.0 (mitigation factors)
