Proper duct design in kitchen fire protection yields which outcomes?

• A. Reduced grease buildup, improved airflow, and effective agent distribution
• B. Higher grease buildup but faster discharge
• C. No effect on airflow
• D. Reduced agent efficiency

Answer: (A)

In kitchen fire protection, how the ductwork is designed directly affects grease control, airflow, and how well the extinguishing agent reaches the fire. Smooth interior surfaces and gentle turns help grease slide down and out of the system rather than accumulate on walls and joints, which reduces fuel sources for a fire and keeps the ducts cleaner. Proper duct sizing and layout also maintain the right exhaust velocity and pressure relationships with the hood fan, so grease-laden air and heat are captured and exhausted efficiently, improving overall airflow and reducing the risk of back-drafting or flow obstructions. When a suppression agent is released, well-planned duct design helps the agent be distributed more evenly through the hood and ductwork, increasing the likelihood that the agent reaches the fire area quickly and covers it effectively. If duct design is poor, grease buildup increases, airflow deteriorates, and agent distribution becomes uneven, undermining fire protection. So the best outcomes are reduced grease buildup, improved airflow, and effective agent distribution.
