NFPA ______ requires turning fuel or electrical power off to cooking appliances upon activation of the extinguishing system.

• A. 70
• B. 96
• C. 92
• D. 101

Answer: (B)

This item tests how a commercial kitchen’s fire suppression system interacts with utility shutoffs. When a kitchen hood suppression system is activated, NFPA 96 requires that fuel and electrical power to the cooking appliances be automatically turned off. This helps prevent continued fuel delivery or electrical ignition sources after discharge, reducing the risk of re-ignition and making firefighting safer and more effective. NFPA 70 covers general electrical installations but not this interlock requirement; NFPA 92 deals with smoke management in ducts; NFPA 101 focuses on life safety but does not specify the automatic shutoff of appliance utilities tied to a kitchen suppression event. Therefore, the standard ensuring the automatic shutdown of fuel or power to cooking appliances upon system activation is NFPA 96.
