Learn about the signs of a potential natural gas leak  

Natural gas is colorless and odorless, so energy companies like Spire add a harmless chemical called mercaptan to make it detectable and protect the communities we serve.

Mercaptan smells like rotten eggs, so if you ever catch a whiff inside your home or on the street, call us right away when you’re safely away from the smell.

Other signs of a natural gas leak can include:

  • A change in the appearance of your pilot light
  • A hissing sound or odor near a pipeline or near a building
  • Ice formation on the ground above a pipeline
  • Distressed or deteriorated plants near a pipeline

If you’re not sure what it smells like, you can request a “Scratch and Sniff” card in the mail to help you learn about this stinky – but important – scent.
