Hazard classification must be made before reviewing which building system plan?

• A. Electrical
• B. Automatic Sprinkler
• C. Fire Alarm
• D. HVAC

Answer: (B)

Hazard classification sets the fire protection design criteria used for sprinkler systems. Once you determine whether the occupancy is light, ordinary, or extra hazard, you establish the required water density, area of operation, types of sprinklers, and hydraulic demand. The sprinkler plan is built to meet those criteria, so confirming the hazard classification first ensures the plan can be properly sized and validated. Other plans—electrical, fire alarm, and HVAC—aren’t driven by hazard classification in the same focused way, so they don’t depend on that determination to the same extent.
