Gas Leak Map

If you smell gas, leave the area and go outside immediately. Once you're safe, call 911 or call us at 718-643-4050 to report the leak.* We’re available to assist 24/7. 

Do not light matches, start your car, or use any electronic appliances that could spark and start a fire. This includes telephones, ovens, household appliances, and even flashlights.

Whether you report a suspected gas leak to 911 or to us at 718-643-4050, we’ll respond and make the area safe. We have crews working 24/7.  

If the leak is in your home or business, we’ll make it safe and will turn off the gas until you can have a plumber or technician make the necessary repairs. 

Outside leaks can be caused by pipe corrosion or cracks resulting from weather or water main breaks. Leaks can also occur as the result of accidental damage during construction or street work. 

Indoor leaks can be caused by faulty appliances, leaky pipe fittings, corroded or cracked pipes or as the result of construction. It’s not always easy to pinpoint the cause of a leak, and you should not investigate a suspected leak on your own. Our technicians are trained in gas leak investigation and repair; they’ll respond quickly and make the area safe. 

In all situations, our crews will be dispatched to investigate the area to ensure safety. 

If the leak is indoors, we’ll turn off the gas until the necessary repairs can be made. 

If the leak is outdoors, the gas usually evaporates into the outside air, helping to reduce the safety hazard. Our crews check the condition of all gas leaks and determine which leaks need to be repaired immediately and which should be monitored depending on the situation, severity of the leak, and proximity to buildings. 

The Reported Gas Leak Map plots all reported, outdoor gas leaks within our service territory. It reflects all confirmed leaks currently under repair and/or monitoring.
