Carbon monoxide (CO) is an odorless, colorless gas produced by the combustion of fuels such as natural gas, oil, and propane in devices including furnaces, water heaters and stoves. These items are normally designed to vent the CO to the outside, but harmful interior levels of CO can result from incomplete combustion of fuel, improper installation, or blockages, leaks or cracks in the venting systems.
Homeowners can take action against potential carbon monoxide poisoning by taking the following preventive steps:
- Have all fuel-burning appliances professionally inspected yearly, preferably before the start of the cold-weather season when heaters and furnaces are first used.
- These appliances include gas stoves and ovens, furnaces and heaters, water heaters, generators, and clothes dryers.
- All such devices should be properly installed and vented to the outside whenever possible.
- If repairs are necessary, be sure they are performed by a qualified technician.
- Always use the proper fuel specified for the appliance.
- Have flues and chimneys for fuel-burning fireplaces or stoves inspected regularly for cracks, leaks, and blockages that may allow a buildup of CO to occur.
- Never use gas stoves or ovens to heat the home, even temporarily.
- Do not start or idle a vehicle in a garage, even with the garage door open.
- Be sure to install a CO detector (either battery operated or plug-in) and follow the manufacturer’s instructions for proper location and installation. Many municipalities now require every home to have a working CO detector.
- Learn what to do should the CO alarm activate: If anyone in the home experiences symptoms such as fatigue, dizziness, blurred vision, nausea, or confusion, everyone should leave immediately and seek medical attention. If no symptoms are felt, open doors and windows immediately and shut off all fuel-burning devices that may be potential sources of CO. All fuel-burning appliances should then be inspected for problems before being used again.
Taking these steps can save your life. Be safe this winter and enjoy the season.
