Which statement is true regarding action when the cooking equipment fire extinguishing system actuates?

• A. All fuel and electric power sources that could produce heat to equipment protected shall be shut down
• B. Only gas supply shall be shut off
• C. Only electrical power shall be cut
• D. No action is required

Answer: (A)

When a cooking equipment fire extinguishing system actuates, the key safety step is to remove any remaining heat sources from the protected equipment by shutting off both fuel and electrical power. The extinguishing agent suppresses the fire, but fuel lines and energized components can still pose a risk of re-ignition if they remain live. Stopping the gas supply eliminates any ongoing fuel that could feed flames, while cutting electrical power prevents arcing or heat from energized equipment that could reignite hot surfaces. If only one type of power is shut off, the other could still cause a reflash; doing nothing is unsafe. So the proper action is to shut down all fuel and electric power sources that could produce heat to the protected equipment.
