What to do if you smell gas

Natural gas is almost pure methane, which does not have any odor. For safety purposes, gas distribution companies must add a chemical odor to natural gas so that it can be detected. On this page, you can find helpful instructions if you smell gas.

If you smell gas inside a building...

Evacuate the building as rapidly as possible and call 911 once outside the building.

• DO NOT TURN ON OR OFF ANY ELECTRIC LIGHTS OR APPLIANCES
• DO NOT OPEN OR CLOSE THE WINDOWS
• DO NOT TRY TO SHUT OFF THE GAS

If you smell gas outside...

Call your gas company from outside the building. If you don't know your gas company, call 911.
