What is the primary safety outcome of keeping ducts clean and unobstructed under NFPA 96?

• A. Safe operation of the exhaust system
• B. Decreased energy use
• C. Increased noise
• D. Improved aesthetics

Answer: (A)

Keeping ducts clean and unobstructed under NFPA 96 centers on preventing grease fires and ensuring the kitchen exhaust system can operate safely. When ducts are free of grease buildup and blockages, airflow remains strong and heat and cooking vapors are removed efficiently. This reduces the chance that accumulated grease will ignite and spread, and it keeps the exhaust equipment functioning as designed. That is why the primary safety outcome is safe operation of the exhaust system.

Lower energy use or improved aesthetics might occasionally come with cleaner ducts, but they aren’t the main safety focus of NFPA 96. Increased noise is not a safety benefit, and aesthetics don’t address fire prevention or system performance.
