Does 811 mark gas lines?

How do I find my buried electrical lines?

They operate slightly differently than magnetic location devices, allowing them to find a signal from a non-ferrous metal. Some utilities have a signal running through them.
What is the hand expose zone for a utility line?
The “hand expose zone” is the zone lying within 1 metre of each side of the locate marks that identify the location of the buried facility.
How deep are water and gas lines buried?

Can tree roots break gas lines?
Many gardeners are aware that tree roots can damage water pipes, but the roots are a threat to gas lines, as well. When planted too close to a gas line, vigorous tree roots are capable of moving the lines and destroying the protective coating on the pipes. Tree maintenance and accidents can also damage gas lines.

The law, in all states, generally provides that anyone excavating must call the 811 utility-locate hotline before digging begins to have all utilities located and marked.
How close may you get to a marked utility when digging?
It’s best to dig a few test holes, and make sure they are at least a foot away from the markers. Sometimes, you will have to expose those lines by hand to ensure you can find and follow the line.
Where are utility lines usually located?
