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.

Smell

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

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

Listen

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