Smell gas? Move fast.

Because natural gas is colorless and has no scent, we add a strong odorant that smells like rotten eggs to help you detect a possible gas leak. If you suspect a leak, call 1-800-ALLIANT (800-255-4268) immediately. We will investigate for free. Gas leaks are dangerous and can result in fires, explosions, injury or death. 
Learn the signs of a leak and what to do.
Signs of a leak

  • Hear hissing, roaring or whistling sounds near a gas appliance, meter or pipeline.
  • See blowing dirt, bubbling water or discolored vegetation in an otherwise green area.

  • Call 1-800-ALLIANT (800-255-4268) from a remote location – do not return until we confirm it is safe.

  • Don’t move appliances or machinery.
  • Don’t strike matches or create a flame/spark of any kind.
