Gas appliances not requiring protection but located under the same ventilation equipment shall _______.

• A. also be shut off
• B. remain powered
• C. be isolated
• D. continue operating

Answer: (A)

When gas appliances share the same ventilation hood, shutting off the gas supply to those appliances is the safest action. The hood area represents a common risk zone: if a fire starts in or near the hood, or if the ventilation system is compromised, continuing to feed gas to any appliance under that hood can fuel the fire or cause gas to accumulate. Even appliances that don’t require extra protection are included because the hazard is tied to the shared ventilation space, not to individual appliance protections. Turning off the gas reduces the fuel available during a fire and helps prevent re-ignition or spreading. Remaining powered, continuing to operate, or isolating individual appliances would not adequately reduce this shared risk.
