Smoking Manholes

Most manhole fires are weather related. A mix of melting snow and road salt, or extreme hot weather, can cause electrical equipment in manholes to smoke or catch fire.

Manhole covers weigh between 70 to 300 pounds. Many are vented to allow gases to escape, rather than build up in the manhole, helping prevent explosions

Switching From Oil to Gas:

  • Con Edison has created a one-stop resource for customers looking to convert to natural gas. Natural gas is an efficient, safe, and reliable fuel source. It costs less than heating oil and is one of the cleanest-burning fuels available - reducing greenhouse gas emissions and improving air quality. We are helping to make a cleaner, greener New York through our gas conversion program. To learn more about converting to natural gas visit:
