Utility Shutoff

Turning Electricity On and Off

Know where your main electrical panel is, so you can turn off the electric supply to your entire facility quickly in case of an emergency.

Turning Off Your Electricity


  • Know where your fuse box or circuit-breaker box is located.
  • Know the correct sizes of any fuses needed and keep spares on hand. Blown fuses must be replaced, not repaired. Do not replace a fuse with one of higher amperage.
  • If a fuse blows, disconnect or turn off the equipment that may have caused the problem.
  • Shut off the main electric switch before replacing a fuse.

Circuit Breakers

  • Know how to reset a circuit breaker. After turning off or unplugging equipment on the circuit, push the switch firmly to the off position, then back on. If the overload is cleared, the electricity will come back on.
  • If your circuit breakers trip off repeatedly, there could be a problem with the equipment on that circuit. If the equipment is unplugged but the circuit breaker trips off again, call an electrician.

Turning Your Gas Off

Knowing the location of your main gas shutoff valve will help you turn off the gas supply to your entire facility quickly in case of an emergency.  If you have natural gas service the valve will be at the gas meter.  If you have propane service the valve will be under the cap on top of the tank.

  • The gas meter and gas service shutoff valve is usually located on the side or in front of the building.
  • In some cases, the gas meter can be located in a cabinet enclosure built into the building or located inside the building.  In these cases, the gas service shutoff valve can be located outside on a section of gas service pipe next to the building, or near the gas meter.
  • If there are multiple meters serving gas to multiple units within a building, there are individual gas service shutoff valves for each unit near each of the gas meters, including a master valve for the entire building where the gas pipe comes out of the ground.  Your facilities personnel or your property manager (if you are leasing) might be able to help you locate your unit’s valve location.
  • If you still are not able to locate the gas service shutoff valve, contact PG&E for assistance to locate the valve.
  • Most rural locations have propane instead of natural gas, and the shutoff valve is under the cap on the tank.  If you have an underground tank, you will only see the cap sticking out of the ground.
  • A wrench is not normally required to shut off a propane supply.  You simply turn the shutoff knob (usually clockwise) until it stops.

When To Turn Off Your Gas

Do not shut off the gas unless you smell gas, hear gas escaping, see a broken gas line or if you suspect a gas leak. If you shut off the gas, there may be a considerable delay before your gas supplier can turn your service on. Once the gas is shut off, do not try to turn it back on yourself.  If the gas service shutoff valve is closed, your gas supplier should perform a safety inspection before the gas service is restored and the appliance pilots are lit.

How to Turn Off Your Gas

In an emergency, your gas can be turned off at the main gas service shutoff valve. If your service is natural gas, use an 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 service is propane, turn the shutoff knob clockwise until it stops.

  • Know where your main gas service shutoff valve is located.
  • Keep an adjustable pipe or crescent-type wrench available to turn off the gas if you have natural gas service.
  • Know how to shut off the gas at the gas service shutoff valve.
  • Leave it off until service can be restored safely by your gas service provider.

If your gas service is configured differently from the ones described and you wish to know how to turn off your gas, contact your gas service provider.

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.

  • Know which of your appliances use gas
  • Know where the appliance gas shutoff valves are located, and how to turn them off
