Gas Safety

Gas leaks can result in fires and explosions. It’s important that you, your family, and your colleagues know how to recognize a gas leak and what to do if you suspect a leak.

How to Recognize a Gas Leak

  • Smell – a distinctive, strong odor similar to rotten eggs
  • See – a white cloud, mist, fog, bubbles in standing water, blowing dust, or vegetation that appears to be dead or dying for no reason
  • Hear – roaring, hissing, or whistling

What to Do If You Think There Is a Gas Leak

  • If the odor is strong, leave immediately and take others with you
  • If you are outside, leave the area immediately
  • Don’t light a match or smoke, turn appliances or lights on or off (including flashlights), use a telephone, or start a car
    • *Doing so can produce sparks that might cause the gas to explode*
  • Use a phone away from the area and call 911 or 1-800-75-CONED (1-800-752-6633)
    • National Grid customers should call 1-718-643-4050
  • You can report leaks anonymously
  • Don’t assume someone else will report it
  • Follow directions from emergency responders who are on site
