Natural gas pipelines are buried underground for natural gas transportation. Wherever pipelines are buried, there will be pipeline markers clearly marking the location. Know where they are in relation to your home and business.
Pipeline leaks are rare but be aware of signs of a leak:
- Dead vegetation, dirt blowing in the air, steady bubbling under water, fire, a dense cloud, or unusual fog
- Hissing or roaring sound.
- Strong, unpleasant odors such as a rotten egg sulfur smell, garlic-like smell, or strong petroleum smell
If a leak occurs:
- Leave the area immediately in an upwind direction and warn others.
- Do not light a match, start an engine, or use a cell phone.
- Avoid possible ignition sources which may cause a fire.
- Call the pipeline operator.
- Do not drive into the area.
- Avoid escaping liquids and gasses.
Many homes have natural gas appliances and climate systems requiring pipelines coming into the house. Be sure to call your provider to schedule line marking before digging near pipelines.
If you smell an odor like rotten eggs or sulfur and think you may have a gas leak in your home:
- Open doors and windows.
- Turn off the gas line coming into your home only if you can do it quickly.
- Leave your home on foot. An automatic garage door opener can ignite natural gas.
- Call your natural gas provider, but
- Do not call from your home or turn off lights before you leave. Sparks from either could ignite gas.
If you smell a rotten egg or sulfur smell in your yard:
- Leave the yard before calling your natural gas provider.
- Avoid possible ignition sources.
- Follow your provider’s advice about whether to stay in your home while they make the repairs.
