Detecting a Leak

To report a natural gas odor or emergency, leave the area immediately, call 911 and then call us 800-458-4251.

SMELL

If you smell a rotten egg or sulfur-like odor in or around your home, at work or in your neighborhood, this odor may be the result of a natural gas leak.
Natural gas is colorless and odorless, so we’ve added an odorant called mercaptan to warn you of a leak.

LOOK

When outside: Blowing dirt, persistent bubbling in puddles, standing water or dead vegetation in an otherwise healthy area are signs of a possible leak.
When inside: If you see a yellow flame instead of a blue flame on your range, furnace or water heater, it’s a warning sign that the natural gas is not burning properly.
This can lead to an increased potential for carbon monoxide poisoning as well as higher fuel bills.

LISTEN

An unusual noise like a hissing or roaring sound can indicate a leak on a pipeline. If you hear a hissing noise around your natural gas piping, meter or appliances, or if your natural gas appliance fails to ignite, you may have a natural gas leak.
Natural gas is flammable and can be ignited by heat, sparks or flames.

Methane Detectors

Methane detectors are available for purchase and help keep your family safe by detecting natural gas in your home. To make sure they work properly, customers should follow the manufacturer's instructions for installation and maintenance.

If you smell gas or have any of these warning signs:

LEAVE the area immediately.
DON'T use electrical equipment.
