You can’t see it, or smell it, but it’s there. Carbon monoxide (CO) -- an invisible, odorless, tasteless and non-irritating gas -- is the leading cause of accidental poisoning in the United States. More than 200 Americans die each year from CO produced by fuel-burning appliances. Another several thousand go to emergency rooms for treatment of CO poisoning.

The incomplete burning of any material containing carbon, such as gasoline, natural gas, oil, propane, coal or wood, produces CO. The first line of defense CO is to make sure all your fuel-burning appliances operate and are maintained properly. These appliances include gas and oil furnaces, water heaters, gas ranges, space heaters, and gas clothes dryers. Improperly vented fireplaces and charcoal grills can also give off CO.

CO Can Be Fatal

According to the National Safety Council, CO interferes with the distribution of oxygen in the blood to the rest of the body. Depending upon the amount inhaled, this gas can disturb coordination, worsen heart conditions, and produce fatigue, headache, weakness, confusion, disorientation, nausea and dizziness. Very high levels can cause death. If you experience any symptoms, seek fresh air immediately.

Be Careful

• Make sure you’re operating appliances efficiently and that they are well maintained.
• Make sure that appliances using combustible gases are well ventilated to remove the carbon monoxide gas from the living space.
• Have your heating equipment inspected each year by qualified technicians.
• Make sure appliances, vents and chimneys are kept clear of debris.
• Do not heat rooms using your kitchen range, which can reduce oxygen levels and cause CO to build up.
• Avoid leaving vehicles running in your garage.
• Equipment like charcoal grills should only be used outdoors.

These are signs that there may be unhealthy levels of CO in your home:

• Your hot water supply is decreasing.
• The furnace is not adequately heating your home.
• Soot appears on appliances.
• Moisture appears on inside walls or windows.

If you notice any of these, call a professional to inspect and determine if CO levels are too high. All PSE&G appliance service technicians are trained and equipped to detect the unhealthy presence of CO in a home.

About CO Detectors

Invest in carbon monoxide detectors only as back-up protection, not as a substitute for proper use and maintenance of the fuel-burning appliances. CO alarms can provide an early warning to consumers before CO builds up to a dangerous level. Most devices cost under $100. The US Consumer Product Safety Commission recommends placing a carbon monoxide alarm in every area of the house. If just one alarm is installed, it should be placed near the sleeping rooms of the house. If you already have one, remember to check the batteries regularly.

PSE&G does not sell or install carbon monoxide alarms. Consumer’s Union, the publisher of CONSUMER REPORTS), the American Gas Association, and Underwriters Laboratories (UL) can help you make an informed decision. Look for UL certification on any alarm you purchase, and carefully follow the instructions for its placement, use and maintenance.
