Smell Gas? Know the Signs of A Gas Leak

  • LOOK for discolored vegetation, blowing dirt or continued bubbling water in the area of a buried gas line.
  • LISTEN for a hissing sound.
  • SMELL for the distinctive “rotten egg” odor of natural gas.

Natural gas is a colorless, odorless fuel. As a safety precaution, we add a chemical odorant called mercaptan that gives natural gas an odor often associated with rotten eggs. This distinctive scent allows you to smell a potential leak if it occurs. Always leave if you suspect a leak.

Natural gas is non-toxic, lighter than air and displaces oxygen. In severe cases, if not used properly, it may lead to asphyxiation, and has a risk of ignition near a spark.

Note: Always leave if you suspect a leak. Be aware that some persons may not be able to detect the odorant because they have a diminished sense of smell, known as olfactory fatigue, or because the odor is being masked by other odors in the area. Certain conditions may cause the odorant to diminish so that it is not detectable. 


Act Fast!leak emergency number

  • Never try to find the leak yourself.
