Pipeline Safety

Call Before You Dig

811 Logo (PNG) Opens in new window811 is the national call-before-you-dig phone number. Anyone who plans to dig should call 811 or go to Texas811's website two business days (excluding weekends and holidays) before digging to request that the approximate location of buried utilities be marked with paint or flags so that you don't unintentionally dig into an underground utility line. This is required even if you're working in your own backyard.

Signs of a potential leak

  • Strong petroleum or sulfur (rotten eggs) odor
  • Dead vegetation or liquid on the ground near a pipeline, dirt being blown into the air or a dense white cloud or fog
  • Hissing, gurgling or roaring sound

If you suspect a leak, Take Action!

  1. Indoors
  2. Outdoors
  • Leave the house or building immediately. Do not turn on or off lights, or use electronic devices, including cell phones in the house or building if you suspect a leak.
  • When you are a safe distance away, call 911 and the gas company.
