Natural Gas Leaks

Smell gas? Move fast.

Smell Gas - Move FastNatural gas is colorless and odorless. Alliant Energy adds an
odorant to give gas its distinctive rotten egg odor so you can smell
a leak. If you suspect a gas leak, call Alliant Energy at 1-800-ALLIANT
(800-255-4268) immediately.

We will investigate a gas leak for free.

The unintentional release of gas is dangerous to you, the public, and could result in fires, explosions, injury or death. Always use extreme caution near a gas leak and recognize the possible hazards.

Signs of a natural gas leak or damaged pipeline:
  • Smell the odor of rotten eggs. If you don’t know the scent, contact Alliant Energy for a free scratch-and-sniff card.
  • Hear hissing or whistling sounds near a gas appliance, meter or pipeline.
  • See blowing dirt, bubbling water or discolored vegetation in an otherwise green area.
What TO DO if you suspect a gas leak:
  • Make sure gas appliances are turned all the way off.
  • Turn off and abandon machinery.
  • Leave the area and keep others away until Alliant Energy allows you to return.
  • Call 1-800-ALLIANT from a remote location.
  • If you hear blowing gas, which is a more serious issue, call 911.
What NOT TO DO if you suspect a gas leak:
  • Do not try to find or repair the leak.
  • Do not attempt to move appliances or machinery.
  • Do not strike matches or create a flame/spark of any kind.
  • Do not use a telephone or cell phone (these can ignite gases or vapors).
  • Do not turn on or turn off any light switches or electrical switches or use garage door openers (these may also ignite airborne gases).
  • Do not attempt to extinguish a burning gas leak.
Additional tips:
  • Individuals with a known inability to smell should consider purchasing a natural gas detector. Some people may not be able to smell the natural gas odor because they have a diminished sense of smell, olfactory fatigue (temporary inability to distinguish an odor after a prolonged exposure to it) or because the odor is being masked or hidden by others, such as cooking or chemical odors. In addition, certain conditions in pipes and soil can cause odor fade (which is loss of odorant) making it undetectable by smell.
  • A qualified professional should check your gas appliances annually. Inspections keep gas appliances safe and efficient, and reduce risks of carbon monoxide poisoning.
  • Outside vents for gas appliances must be cleared following a major snow or ice storm to enable proper venting and prevent carbon monoxide accumulation.
  • Keep gas service equipment clear during the winter. Use a broom or your hands. Kicking or using a shovel to clear snow could damage the equipment.
  • Do not operate snow plows or snow blowers next to gas meters.
