NFPA __________ requires turning fuel or electrical power o cooking appliances upon activation of the extinguishing system.

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

Answer: (D)

The requirement to turn off fuel and electrical power to cooking appliances when the extinguishing system is activated comes from NFPA 96, which covers commercial cooking operations, hoods, and their fire protection systems. NFPA 96 specifies that when the suppression system discharges, the fuel supply (usually gas to the burners) and the electrical power to the cooking appliances should be shut off automatically. This prevents continued fuel or energized equipment from posing a re‑ignition or electrical hazard after the system has released its agent, ensuring a safer and more effective suppression.

NFPA 70 (the NEC) focuses on electrical installations in general and does not mandate this interlock tied to a cooking-fire suppression event. NFPA 101 (Life Safety Code) addresses occupant safety and egress but not this specific equipment interlock. NFPA 13 covers sprinkler system installation overall, not the automatic shutoff of cooking equipment when a cooking-system extinguisher is activated.
