Knowing the location of your main gas service shutoff valve will help you turn off the gas supply to your entire facility quickly in case of an emergency.
The location of the valve can vary depending on the type of building and when it was installed:
Gas Shutoff Valve
Cabinet Meter Outside
If you still are not able to locate the gas service shutoff valve, contact PG&E for assistance to locate the valve.
Gas Service Shutoff Valve
In an emergency, your gas can be turned off at the main gas service shutoff valve normally located near your gas meter. Using a 12 to 15 inch adjustable pipe or crescent-type wrench or other suitable tool, give the valve a quarter turn in either direction; the valve is closed when the tang (the part you put the wrench on) is crosswise to the pipe.
If your gas service is configured differently from the one described and you wish to know how to turn of your gas, please contact PG&E.
Appliance Gas Shutoff Valve
Most gas appliances have a gas shutoff valve located near the appliance that lets you turn off the gas to that appliance only. In some cases, turning off the gas at the appliance's shutoff valve will suffice if there is a gas leak or the appliance needs to be replaced or serviced. You should have an appliance gas shutoff valve installed at each gas appliance that lets you turn off the gas to that appliance only, instead of shutting off all gas at the main gas service shutoff valve. To turn off the gas at the gas appliance, rotate the valve a quarter turn.
