When inspecting a kitchen hood and duct, you should pay attention to which of the following?

• A. Cleanliness of duct work
• B. Noise levels
• C. Surrounding area
• D. Ventilation rate

Answer: (A)

Grease buildup in kitchen hoods and ducts is the key fire safety concern. Grease is highly flammable, and when it accumulates in the ducts, hoods, and on filters it creates a fuel load that can ignite and quickly spread through the exhaust system. Keeping ductwork clean reduces this fuel load and helps maintain proper airflow, which is essential for venting heat and flames away from the building. During an inspection, you’d verify that duct surfaces, hoods, and filters are free of grease, that cleanouts and access panels are present and usable, and that cleaning is performed on a regular schedule with records kept. While noise, surrounding area, and ventilation rate matter for other reasons, they don’t address the immediate fire hazard created by grease-laden ducts in the same way.
