A faint odor of natural gas indoors may mean a pilot is out on a gas appliance. Check it. You can correct this situation easily and safely. If you're not sure what to do, call PECO or your repair service.
Never use matches to look for gas leaks and never try to look for the leak yourself. Don't flip a switch, since they can create sparks, and don't use any other electrical equipment.
If you smell natural gas or see downed power lines, leave the area immediately. Then call PECO at
1-800-841-4141, this number is available 24 /7.

Although there may be no problem in your house, you should be alert to the causes and symptoms of carbon monoxide poisoning.
Common causes of carbon monoxide poisoning are malfunctioning heater vents or clogged chimneys. They should be checked occasionally to make sure they are free from obstructions.
Your heater also releases water vapor that must get out through a vent or chimney. Otherwise, moisture in the chimney can cause gradual erosion of the chimney.
If you have concerns, get expert advice from your heating service company, or call PECO at
A buildup of carbon monoxide (CO) from incomplete combustion of fuels, such as natural gas, and inadequate ventilation can cause carbon monoxide poisoning. Signs of buildup of this colorless, odorless gas include:
Stuffy, stale or smelly air
Soot from fireplaces or furnaces
Exposure to carbon monoxide gas can cause headaches, dizziness, weakness, nausea, vomiting, and loss of muscle control. Prolonged exposure leads to unconsciousness, brain damage, or death. The best treatment for overexposure is fresh air and immediate medical help.
To reduce the risk of carbon monoxide poisoning, gas and oil appliance manufacturers recommend a yearly safety check-up.
To prevent accidental CO poisoning, keep the following tips in mind:
Never operate a CO-producing engine or heating source in a confined area that lacks ventilation. Examples include leaving a vehicle running in a closed garage, operating a grill indoors, or leaving a cooking range on for warmth.
Have heating systems, gas hot water heaters, and chimneys checked annually by qualified technicians or contractors.
Install CO detectors (meeting UL standard #2034 requirements) above your home's furnace and outside bedrooms.
If you suspect a CO problem with your furnace or water heater, call a qualified heating contractor immediately.
EFVs are able to automatically reduce unplanned, excessive gas flows in the event of a broken gas line.
An excess flow valve (EFV) is a device that can reduce the risk of a natural gas leak in the event of damage to the outside service line. EFVs are able to automatically reduce unplanned, excessive gas flows in the event of a broken gas line, often the result of excavation damage.
However, EFV's can only shut off the excessive gas flow if the damage occurs between the gas main and the customer's regulator/meter installation.
An EFV cannot address gas leaks or issues with internal customer gas piping and/or appliances.
As a result of regulations enacted by the Pipeline and Hazardous Materials Safety Administration (PHMSA) of the U.S. Department of Transportation, PECO has been installing EFV's on the gas service lines of certain single family residences – either when a new service line is installed or when an existing service line is replaced. With certain exceptions, customers whose natural gas load does not exceed a certain size have the right to request an EFV installation on their existing natural gas service line.
PECO will install an EFV on eligible existing natural gas service lines. This work can be completed at a cost of approximately, $1,400-$2,000, with the actual cost depending on the individual circumstances of each job. These costs would be the responsibility of the customer requesting the EFV installation.
