### Hazard classification is the single most consequential design decision for a sprinkler system because it directly determines the design density, the design area, and therefore the flow and pressure demand on the water supply. {note}
+### The hazard classification shall be assigned by the designer based on the occupancy descriptions in NFPA 13 Chapter 5 and shall be confirmed with the Owner and the AHJ prior to finalizing the hydraulic design.
