Suspect a gas leak?

Gas leak

What to do

  • Make sure gas appliances are turned all the way off.
  • Turn off and abandon machinery.
  • Leave the area and keep others away.
  • Call 1-800-ALLIANT from a remote location – do not return until we confirm it is safe.
  • If you hear blowing gas, which is a more serious issue, evacuate to a remote location and call 911.

What not to do

  • Don’t try to find, repair or extinguish a burning leak.
  • Don’t move appliances or machinery.
  • Don’t strike matches or create a flame/spark of any kind.
  • Don’t use a telephone or cellphone until you are out of the area. (These can ignite gases or vapors.)
  • Don’t turn on or off any light or electrical switches or use garage door openers. (These may also ignite airborne gases.)

How natural gas gets to you

Natural gas comes from the earth. It travels to your community through underground transmission pipelines.

There are more than 2 million miles of pipelines in the U.S. Pipelines are a safe and reliable way to transport natural gas, and accidents are relatively rare.

When the gas gets to your community, the local distribution company, such as Alliant Energy, takes the gas and adds the odorant to help detect leaks.

Inside your community, the gas travels through pipelines called mains. Mains are often buried under or along streets. From there, a smaller service line brings the gas to your meter. Service lines are buried in the yards.

After the gas passes through a meter, it belongs to the customer. Customers are responsible for installing and maintaining the piping that natural gas flows through to reach appliances and equipment.

How we’re working to keep natural gas safe for you

Woman in kitchen

We provide training and education on natural gas to keep our employees, customers and communities safe. Stringent safety standards govern the exploration, production, transportation, distribution and use of natural gas. We continuously seek out new technologies in pipeline design, construction, inspections and operations to make delivery of natural gas safe, cost-effective and secure.

Don’t rely on your nose alone: Get a natural gas detector

Alliant Energy adds a distinct odor to natural gas to alert you of a potential leak. But, there are some situations in which your sense of smell alone may not be enough to detect a leak. Individuals with a known inability to smell are especially vulnerable. 

You should not rely solely on your sense of smell to determine if natural gas is present. Purchase and install a natural gas detector for another layer of protection.

Some people may not be able to detect the odorant because they have a diminished sense of smell or because they have smelled the same odor for too long (olfactory fatigue). Additionally, other odors in an area – like cooking or chemical smells – can mask the smell of the odorant we add to natural gas. Certain conditions in pipes or soil may also cause the odor to fade. In all of these cases, your sense of smell is not sufficient to detect a natural gas leak.

Do you know where utility lines are buried on your property?

Communities have many different buried utility lines, including natural gas pipelines, electrical, water, cable and internet lines.

Homeowners and contractors who don’t call 811 before they start digging or excavating is the leading cause of pipeline accidents.

A call to 811 will send a professional locator to your property to mark a natural gas pipe or other utility-owned lines in the ground leading up to your meter. Locators will not mark privately owned fuel lines, like those running to a garage, pool or fireplace. Privately owned lines are not installed or maintained by Alliant Energy, and customers are responsible for them.

Follow these three rules:

  1.  Call 811 before you dig. 811 is the national phone number that initiates the process of locating and marking the underground utility lines in your yard or at your job. Call 811 at least two business days before you dig.
  2. Wait the required time for utility lines to be marked. Personnel from the One Call Center will notify us to mark the approximate locations of buried gas or electric lines with high-visibility safety paint and/or flags. There is no charge for this locating service.
  3. Respect the marks or flags, and dig with care. When you start digging, stay at least 18 inches away from the marked lines. Hand dig with extreme caution if you must excavate within the safety tolerance zone.

Call 1-800-ALLIANT if your digging equipment or tools contact our underground pipelines or electrical lines. Even minor damage, such as nicks, scratches, cuts, scrapes, dents and gouges, can result in pipeline failure, electric shock or a major incident in the future if not properly assessed. If you hear blowing gas, which is a more serious problem, call 911 immediately from a safe location.
