Any gas appliance not requiring protection but located under ventilating equipment where protected appliances are located shall be ______________________________.

• A. Shut off manually
• B. Remain energized
• C. Automatically shut off upon activation of the extinguishing system
• D. Ventilate

Answer: (C)

When a fire suppression system is activated in an area with gas appliances, the gas supply to certain appliances must be cut automatically. This is done to stop the flow of fuel at the moment the extinguishing agent is released, preventing more gas from feeding the fire or creating gas buildup while the system is doing its job. If gas stayed on, even with the fire being suppressed, the fuel could reignite or accumulate, undermining safety. This automatic shutoff is particularly used for gas appliances that do not themselves require protection but are located under ventilating equipment where protected appliances are served by the same suppression system. The interlock ensures the fuel supply is isolated as part of the overall fire protection strategy, rather than relying on a manual action or waiting for ventilation to clear the space. Ventilation alone does nothing to stop the gas flow, and leaving the appliance energized would simply provide more fuel for the fire.
