Which NFPA standard governs turning off fuel or electrical power to cooking appliances upon extinguishing system activation?

• A. NFPA 96
• B. NFPA 101
• C. NFPA 13
• D. NFPA 70

Answer: (A)

The concept here is how the fire suppression system for a commercial kitchen interacts with the power and fuel supplies to the cooking equipment. When a kitchen fire suppression system activates, it’s important to automatically shut off the heat source and power to the involved appliances to prevent continued fuel feeds or electrical arcing that could reignite the fire. This specific interlock requirement is defined in NFPA 96, the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations. NFPA 96 covers the installation and operation of kitchen exhaust hoods and fire suppression, including automatic interlocks that cut off gas and, where applicable, electrical power to cooking equipment when the suppression system is activated. NFPA 101 focuses on life safety in buildings, not the detailed interlock requirements for kitchen equipment. NFPA 13 covers the design and installation of automatic sprinkler systems. NFPA 70 is the National Electrical Code, which governs electrical installations but not the specific fire suppression interlock provisions for cooking appliances.
