Know the Signs of a Natural Gas Leak

Natural gas is a clean-burning, efficient fuel that is naturally odorless and colorless. To assist with leak detection, City Utilities adds a foul-smelling odorant to natural gas before delivering it to customers. If you smell rotten eggs, see unexpected dead vegetation or hear hissing from a natural gas line, there may be a natural gas leak. Our natural gas brochure offers a guide to safe and reliable natural gas use.

If You Suspect a Natural Gas Leak:

  • DO NOT use matches, lighters, cigarettes or e-cigs.
  • DO NOT turn on or off electrical switches, appliances or lights.
  • DO NOT use a phone or electronic device.
  • DO NOT ring the doorbell.

It is important for everyone in your family to recognize the smell of natural gas. Not sure of the smell? Call (417) 863-9000 to request a scratch and sniff card.  Natural gas detectors are recommended for individuals with diminished or no sense of smell. Most gas detectors plug into an electrical outlet and must be mounted on the wall. Check with local home building stores for purchase and follow the recommended guidelines for installation.
