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

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

Answer: (B)

The requirement to shut off fuel or electrical power to cooking appliances when a kitchen extinguishing system is activated is addressed by NFPA 96. This standard governs commercial cooking operations, including the ventilation hood, exhaust, and associated fire suppression systems. It specifies that when the extinguishing system discharges, the fuel supply to gas-fired appliances and the electrical power to the cooking equipment should be shut down to prevent continued fuel flow or energized equipment, reducing the risk of re-ignition and electrical hazards. NFPA 70 deals with electrical installations in general, NFPA 13 covers sprinkler systems, and NFPA 101 is the Life Safety Code. None of those prescribe the specific automatic shutdown of cooking appliances upon extinguishment discharge in the way NFPA 96 does for commercial kitchens.
