Recognize and Report a Natural Gas Leak
First and foremost will be the smell of rotten eggs, or sometimes a sickly sweet smell. Natural gas on its own has no detectable odor. Mercaptian is a chemical that is added to the gas to give it its distinctive odor. This is a very concentrated odorant that helps you detect a very small leak quickly. The City of Shelby has Scratch and Sniff pamphlets to give you an idea of what natural gas smells like. They are available at Customer Services in City Hall and also at the Utility Operations Center.
Secondly, you may hear a hissing noise. This would happen in the event of a cracked fitting or connection. If outside, it may be a cut or broken line (Note: A gas meter does make a noise when it is operating. This is normal.).
Some other signs of a possible gas leak are:
- Dead vegetation caused by the leaking natural gas displacing the oxygen in the ground.
- Bubbles may appear in a wet area such as a puddle in your yard near a gas service line or a gas main.
- A dry spot in a moist field. Natural gas has a very low humidity level.
- A fire or explosion on or near a pipeline facility.
- Underground leaks can cause dust or dirt to be blown into the air.
If you encounter any of these situations, remember to always be safe. Evacuate the building or move to a safe location. If you have any doubts, do not hesitate to call 911.
