Smell Gas, Act Fast
Even if the odor isn’t very strong, you should still leave the area immediately, taking others, and then call. Don’t assume someone else has already called. You don’t have to give your name.
Don’t light a match, smoke, flip a switch, ring a doorbell, or touch appliances or electronics, including your phone. Doing so can produce sparks that might cause the gas to explode.
What does natural gas smell like?
Since natural gas doesn’t actually smell like anything, a chemical called mercaptan is added to help you detect a leak. Mercaptan has a very distinct and unpleasant odor that many people compare to the smell of rotten eggs.
Certain conditions or circumstances may diminish the smell of mercaptan. If you have a weak sense of smell, odor fatigue from smelling the same aromas for an extended period, or if multiple competing odors are in the area, you may not be able to detect the odorant.
Physical or chemical processes may cause the odorant to fade to the point where it’s no longer detectable, including:
- Adsorption, absorption, and oxidation.
- Newly-installed metal, or sometimes plastic, piping (utility or customer).
- Size, length, and configuration of the piping.
- The presence of rust, moisture, or other substances in the pipe.
- Gas composition, pressure, and/or flow. Intermittent, little, or no flow over an extended period of time may result in the loss of odorant until gas flow increases or becomes more frequent.
- If a natural gas leak occurs underground, the surrounding soil may cause odor fade such that the odorant may not be detected by smell in the atmosphere.
If you suspect a gas leak but can’t smell it, you should still find a phone away from the area and call 911 or 1-800-75-CONED (1-800-752-6633).
Safety Starts in Your Home
- Make sure all burners are turned completely off when you’re done cooking and before you leave the house.
- Your pilot light should always be on. Blowing out the pilot light doesn’t stop gas from escaping and can be dangerous.
- Call a professional if you need to move or replace a gas-fired appliance, like a stove or clothes dryer.
- Regularly check the flexible connector that brings gas to an appliance. Over time, it may become brittle and develop small cracks. If the connector is old and dried out, replace it.
- Don’t step, sit, lean, or place any objects on flexible connectors attached to appliances.
- Prevent gases from entering your home through sewer lines by making sure that indoor sewer-line caps are in good shape and attached tightly.
- Keep cleaning products, gasoline, paints, and other flammable materials away from gas appliances.
- Keep kids away from gas appliances.
- Have your heating and ventilation system serviced regularly, and don’t let snow, ice, leaves, or other debris block their vents and exhaust ducts.
- Keep a clear path to and around your gas meter. Use a brush, not a shovel, to remove snow and ice from around your gas meter and the pipes leading to it.
