Excavation Safety

Pipelines Near Your Job Site

Do you always call One-Call before beginning an excavation project?

Excavation activity is the most common source of serious pipeline damage and can cause loss of life and property.

Protect your employees, equipment and company reputation by verifying the location of pipelines and underground utilities before you dig and by knowing how to identify, respond to and prevent a pipeline leak or rupture.

Remember, always call 811 before you dig!

Call 811 or your local One-Call organization at least two working days before you plan to dig and wait until the lines are marked to begin your project. One-Call is a free service.
