How to recognize a natural gas leak

  • SMELL an odor similar to rotten eggs, even if it’s faint or momentary.
  • HEAR an unusual hissing or roaring sound coming from the ground or an above-ground pipeline.
  • SEE dirt or water blowing into the air, discolored vegetation surrounding a pipeline, or standing water continuously bubbling.

What to do if you suspect a leak

  • Leave the area immediately.
  • From a safe place, call 911 and Southwest Gas at 1-877-860-6020, day or night. A Southwest Gas representative will be there as soon as possible.
  • Don't smoke or use matches or lighters.
  • Don't turn on or off any electric switches, thermostats, or appliance controls or use automated doors.
  • Don't start or stop an engine.
