Detecting a leak

Use your senses of sight, hearing and smell, along with any of the following signs, to alert yourself to the presence of a gas leak.


We add an organic compound called Mercaptan to our natural gas and propane before it is delivered to your community. Mercaptan smells like rotten eggs.


Look for a damaged connection to a gas appliance; dirt or water being blown into the air; dead or dying vegetation (in an otherwise moist area); fire or explosion near a pipeline; exposed pipeline after an earthquake, fire, flood or other disaster


An unusual sound, such as a hissing, whistling, or roaring sound near a gas pipeline or appliance.
