Subterranean pipelines are an invisible hazard and exposed pipelines may not be very well marked.  

So Where Are the Pipelines?

Signs indicating a pipeline’s location are often placed along its path. Pay attention to these signs to help prevent accidents. And if you see something you think may be an exposed pipeline, treat it as if it is. The Texas Railroad Commission provides a map of pipelines across the state. Look up your area by selecting your county. Know what's below. Call 811 before you dig.

How Can I Prepare?

  • Learn about the location of pipelines near you and always call 811 before you dig
  • Familiarize yourself with “escape routes” in and around your neighborhood
  • Be ready to evacuate quickly by gathering important documents and creating a kit
    • If you had only 3 minutes to evacuate, are you ready? What would you take?

What to do in the event of a leak


  • Leave the area immediately on foot
  • Warn others in the area
  • Refrain from activities that could cause heat sparks
  • Notify 911 of the leak when you reach safety


  • Light a match, start an engine, or switch electrical equipment on and off (including lights)
  • Attempt to use a cell phone until you have left the area—it can potentially cause a spark
  • Drive into a vapor cloud
  • Make contact with any escaping material, some products may be toxic or corrosive
