How can you recognize a pipeline leak?

Sight, sound, and smell are helpful in detecting pipeline leaks.

Sight

Look for:

  • Crude oil or liquid petroleum products on the ground
  • A dense white cloud or fog
  • A spot of dead vegetation in an otherwise green location (may indicate a slow leak)
  • Flames (if the leak has ignited), do not attempt to extinguish any primary fire source until pipeline company employees arrive and their representative directs this action.

Sound

Listen for:

  • A roaring sound
  • A hissing sound

Smell

Smell for:

  • A pungent odor, sometimes like "rotten eggs"
  • A gasoline-like odor
