What is hazard & commodity classification?
Hazard and commodity classification is the critical engineering process of determining how stored or handled materials are categorized so that the appropriate level of fire protection can be established. This includes evaluating the fuel load, heat release rate, and physical characteristics of materials to determine required sprinkler density, control area requirements, and building occupancy group.
Accurate classification ensures that safety systems are neither under-designed (unsafe) nor over-designed (unnecessarily expensive), providing a calibrated defense tailored to the specific risks present in the facility.
What we cover
Commodity Classification
Evaluation of Class I-IV commodities and Group A, B, and C plastics to determine NFPA 13 design criteria.
Hazardous Materials Inventory (HMIS)
Detailed analysis of chemical inventories to classify health, physical, and environmental hazards per IFC/IBC.
MAQ & Control Areas
Calculation of Maximum Allowable Quantities and definition of control areas to optimize chemical storage without triggering H occupancy.
High-Hazard (Group H) Determination
Rigorous determination of when a facility exceeds MAQs and must be classified as a high-hazard occupancy.
Why it matters
Classification is the primary driver for every downstream design decision. Misclassification leads to costly retrofits, failed inspections, and catastrophic safety failures.
Drives sprinkler density and water supply requirements. Determines building construction type and fire-rated separations. Critical for obtaining hazardous materials permits and C of O. Ensures compliance with insurance carrier requirements (FM Global/AXA). Optimizes operational flexibility for future product mix changes.
