With colder weather on the way, New York State Electric & Gas is reminding customers how to stay safe around natural gas.
The company is urging people to act fast if they suspect a gas leak — by getting up, getting out, and getting away — then calling 911 or NYSEG at 800-572-1121 from a safe spot.
“There are more than 271,000 natural gas customers and 8,000 miles of gas lines in our service area,” said Tom Scappaticci, vice president of gas engineering and operations. “As gas use goes up in the winter, it’s critical people know the signs of a leak.”
Gas leaks are most often identified by smell, sight, or sound. Natural gas itself has no scent, but utilities add a chemical that smells like rotten eggs to help people detect leaks quickly.
Other signs can include:
- A white cloud, fog, or mist near a gas line
- Bubbles in standing water or dust blowing without wind
- Vegetation that appears dead or dying for no reason
- Hissing, roaring, or whistling sounds near a pipe
What to do if you suspect a leak
- Leave the area immediately — don’t try to find the source.
- Don’t smoke, flip light switches, or use electronics. A spark could cause an explosion.
- Call NYSEG or 911 once you’re far away from the leak.
- Report any nearby digging or sewer work, which can damage gas lines.
NYSEG says it inspects gas meters, pipelines, and service lines regularly using leak detectors and visual checks. Some inspections require access to homes or businesses. If customers are contacted about this, they should call their local NYSEG office to set up an appointment.
The company also tests meters for accuracy, which may involve swapping out the device and checking nearby appliances.
NYSEG also warned about carbon monoxide — a colorless, odorless gas that can be deadly. It’s created by incomplete combustion from things like heating systems or blocked vents.
To protect your household:
- Install a carbon monoxide alarm.
- Have your furnace, chimney, and vents professionally inspected.
- If you suspect carbon monoxide, leave right away and call 911 or NYSEG.
