The reason you need to know this is sometimes in rare cases a natural gas pipeline might actually be run through a sewer pipe, and if a plumber unknowingly strikes a gas line while cutting through a sewer pipe for a repair, natural gas could enter the sewer system creating a very dangerous situation!
For this reason, it's very important that everyone digging call 811 to have all utility lines clearly marked.
Always assume there is a possibility of crossed lines. If a natural gas pipeline is hit:
- Leave the premises immediately
- Instruct others to leave right away and stay away
- Call 911
DO NOT
