Recognize and Respond to a Natural Gas Leak

There are a number of different ways to identify a potential natural gas leak.

Look

If you see:

  • A damaged connection to a natural gas appliance
  • Dirt, water or debris being blown into the air
  • A dry patch of grass in your yard (in an otherwise moist area)
  • A fire or explosion near a pipeline
  • Exposed pipeline after an earthquake, fire, flood or other disaster

Listen

  • If you hear an unusual sound, such as a hissing, whistling or roaring, near a natural gas line or appliance.

Smell

  • If you smell the distinctive odor of natural gas, often described as a sulfur-like odor.
  • Note: some people may not be able to smell the odor for a number of reasons (see below).


 

What to Do if You Suspect a Natural Gas Leak

If you smell a natural gas odor, hear the hissing sound of gas escaping or see other signs of a leak:

  • IMMEDIATELY EVACUATE the area, and from a safe location either call 911 or SoCalGas at 1-800-427-2200
  • DON'T smoke, or light a match, candle or other flame.
  • DON'T turn electrical appliances or lights on or off, operate motorized equipment or vehicles, or use any device that could cause a spark.
