Hazard classification must be completed prior to reviewing which system plan?

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

Answer: (D)

Hazard classification sets the design basis for fire protection systems, especially the automatic sprinkler system. When you classify the hazards in a building, you determine whether the design should be based on light, ordinary, or extra hazard levels, which directly drives sprinkler requirements such as head types, spacing, density, hydraulics, and water supply. Because the sprinkler system design hinges on that classification, you complete hazard classification before reviewing the plan for the automatic sprinkler system to ensure the layout and calculations match the intended protection level. The other plans—fire alarm, HVAC, and ductwork—are influenced by occupancy and overall safety goals, but they don’t rely on the hazard classification to the same extent for their primary design criteria. Once the hazard category is established, you can review the sprinkler plan with the correct design basis in mind.
