Gas Line Safety
  • Never assume that a pipeline is located directly between two markers or directly beneath a marker.


  • Make sure that markers are maintained and not removed for any reason.


  • Provide adequate illumination at night in all work areas, particularly near pipeline right-of-ways. Make sure that markers are visible at all times.


  • Maintain a safe distance between active mining and the pipeline right-of-way.
