NFPA 96 addresses interference with exhaust airflow to prevent what?

• A. Reduced energy consumption
• B. Noise increase
• C. An obstruction that could compromise safe operation
• D. Color of ductwork

Answer: (C)

NFPA 96 focuses on keeping the exhaust system for cooking operations unobstructed so it can reliably remove heat, smoke, and grease-laden air. When something blocks or slows the exhaust path—whether it’s buildup, objects in the duct, or improper clearances—the airflow is reduced. That can allow grease to accumulate and heat to rise, creating a higher fire risk and the potential for unsafe operation of the kitchen ventilation system. The standard emphasizes keeping hoods, ducts, and exhaust fans clear and properly sized to maintain a safe, effective flow path. The other options aren’t the safety issue NFPA 96 targets here: reducing energy use or increasing noise aren’t primary concerns of this standard, and the color of ductwork has no bearing on safe operation.
