Southern California Gas Company is urging customers to be safe and know the signs of a natural gas leak and what to do if a leak is suspected.

Use your sense of sight, hearing or smell to alert you to the presence of a gas leak. Signs of a possible leak include a damaged connection to a gas appliance, dirt or water being blown in the air, dead or dying vegetation (in an otherwise moist area) over or near pipeline areas, a fire or explosion near a pipeline or exposed pipeline after an earthquake, fire, flood or other disaster.

Signs can also include an unusual sound, such as a hissing, whistling or roaring sound near a gas line or appliance and the distinctive odor of natural gas.

If a leak is suspected, don't light a match and don't turn any electrical devices on or off. Immediately leave the area where the leak is suspected and call Southern California Gas from a safe location at (800) 427-2200.
