Alliant Energy has natural gas pipeline assets in Illinois, Iowa, Minnesota and Wisconsin. It's important to know the risks of working around natural gas pipelines. The most obvious and unfortunate cost of accidental contact with gas mains is injury or death. Contact with natural gas facilities can also increase insurance premiums and workers' compensation payments, and can damage equipment.
Contractors are responsible for damage to pipelines that occur while they are working on a construction site. Hitting an underground gas pipeline can become a dangerous proposition, leading to injured workers and bystanders.
If you contact an underground natural gas pipeline, report the incident to Alliant Energy or your local natural gas utility company immediately. Even if the pipe does not appear to be damaged, or no gas seems to be leaking, it needs to be professionally inspected by utility crews before excavation is filled back in. Even a minor scrape to a pipeline could cause major safety problems in the future.
When a natural gas pipeline is accidentally damaged by construction equipment, the gas leaks out and you may hear a hissing, blowing or roaring sound. You may also notice a gas or petroleum odor. Because natural gas is lighter than air, it rises and mixes with the air. And when mixed with air, natural gas can be explosive. To burn or explode, natural gas needs an ignition source. Examples of ignition sources include open flames, electrical sparks, mechanical sparks and static electricity discharges.
