Natural gas is colorless and odorless. An odorant called mercaptan is added to natural gas to give it a distinctive smell, similar to rotten eggs.
You can use your senses to detect natural gas:
- Smell – Smelling rotten eggs, sulfur or petroleum
- See – Blowing dirt, bubbling water or dead vegetation
- Hear – Hearing a hissing, roaring or whistling sound
If you smell, see or hear natural gas, you may have a natural gas leak.
If you suspect a leak, STOP, LEAVE and CALL:
- Stop what you’re doing – Don't light a match or candle or operate anything that could cause a spark, including phones, lights, appliances, doorbells, flashlights and power tools. Don't open the windows and doors in an attempt to ventilate the building. Don’t try to find the leak yourself or operate pipeline valves.
- Leave the area immediately – If you're inside, get out immediately. If you're outside, leave the area quickly.
- Call 911 and Columbia Gas – From a safe location, away from the building, call 911 and Columbia Gas at 1-888-460-4332 and wait for crews to arrive.
