Excavation damage continues to be a leading cause of serious pipeline incidents. Contractors or excavators that hit a line are responsible for damages that occur. Not only does this create a dangerous situation to both workers and bystanders, it often means the excavator will have to pay for property damage, personal injuries, increased insurance premiums, and fines.

By knowing the following prevention, recognition and response information, you’ll be doing your part to keep yourself and those around you safe.

Call 811 before you dig

  • One call to 811 gets underground utility-owned lines marked for free.
  • Whether you're a homeowner or professional excavator, every digging job requires a call - even small projects.

How to recognize a natural gas leak:

  • SMELL an odor similar to rotten eggs, even if it's faint or momentary.
  • HEAR an unusual hissing or roaring sound coming from the ground or an above-ground pipeline.
  • SEE dirt or water blowing into the air, discolored vegetation surrounding a pipeline, or standing water continuously bubbling.

What to do if you suspect a natural gas leak:

  • Leave the area immediately.
  • Move to a safe location and call 911 and Southwest Gas at 1-877-860-6020 day or night. Remain at this location until fire department and Southwest Gas emergency crews arrive.
  • Don't smoke.
  • Secure the area and keep all bystanders and traffic from entering.
  • Don't enter the area where natural gas is escaping.
  • Eliminate nearby sources of ignition, such as sparks or flames.
  • Don't turn on or off or attempt to move equipment near the line break.
  • Don't attempt to repair any damage or control the flow of natural gas.
  • Don't attempt to extinguish a fire should ignition of escaping natural gas occur.
