Carbon monoxide (CO) is an odorless, colorless, deadly gas. It can kill you before you know it because you can't see it, taste it or smell it. At lower levels of exposure, it can cause health problems. Some people may be more vulnerable to CO poisoning such as fetuses, infants, children, senior citizens and those with heart or lung problems. When CO is breathed in by an individual, it accumulates in the blood and forms a toxic compound known as carboxyhemoglobin (COHb). Hemoglobin carries oxygen in the bloodstream to cells and tissues. Carbon monoxide attaches itself to hemoglobin and displaces the oxygen that the body organs need.
 
Carboxyhemoglobin can cause headaches, fatigue, nausea, dizzy spells, confusion and irritability. Later stages of CO poisoning can cause vomiting, loss of consciousness and eventually brain damage or death.
 
Carbon monoxide is a by-product of combustion of fossil fuels. Fumes from automobiles contain high levels of CO. Appliances such as furnaces, space heaters, clothes dryers, ranges, ovens, water heaters, charcoal grills, fireplaces and wood burning stoves produce CO. Carbon monoxide usually is vented to the outside if appliances function correctly and the home is vented properly. Problems occur when furnace heat exchanger crack or vents and chimneys become blocked. Insulation sometimes can trap CO in the home.
 
The Consumer Product Safety Commission and the Lyndhurst Fire Department recommend installing at least one carbon monoxide detector with an audible alarm near the bedrooms. If a home has more than one story, a detector should be placed on each story.
 
The following is a checklist for where to look for problem sources of CO in the home:
 
1.) A forced air furnace is frequently the source of leaks and should be carefully inspected.
 
2.) Measure the concentration of carbon monoxide in the flue gases.
 
3.) Check furnace connections to flue pipes and venting systems to the outside of the home for signs of corrosion, rust gaps, and holes.
 
4.) Check furnace filters and filtering systems for dirt and blockage.
 
5.) Check forced air fans for proper installation and to assure correct air flow of flue gases. Improper furnace blower installation can result in carbon monoxide build-up because toxic gas is blown into rather than out of the house.
 
6.) Check the combustion chamber and internal heat exchanger for cracks, holes, metal fatigue or corrosion. Be sure they are clean and free of debris
 
7.) Check burners and ignition system. A flame that is mostly yellow in color in natural gas fired furnaces is often a sign that the fuel is not burning completely and higher levels of carbon monoxide are being released. Oil furnaces with similar problems can give off an oily odor. Remember you can't smell carbon monoxide.
 
8.) Check all venting systems to the outside including flues and chimneys for cracks, corrosion, holes, debris, blockages. Animals and birds can build nests in chimneys preventing gases from escaping.
 
9.) Check all other appliances in the home that use flammable fuels such as natural gas, oil, propane, wood or kerosene. Appliances include water heaters, clothes dryers, kitchen ranges, ovens or cook tops: wood burning stoves, gas refrigerators.
 
10.) Be sure space heaters are vented properly. Invented space heaters that use a flammable fuel such as kerosene can release carbon monoxide into the home.
 
11.) Barbecue grills should never be operated indoors under any circumstances nor should stove tops or ovens that operate on flammable fuels be used to heat a residence.
 
12.) Check for closed, blocked or bent flues, soot and debris.
 
13.) Check the clothes dryer vent opening outside the house for lint.
 
To further reduce the chances of you or a loved one becoming overcome by carbon monoxide poisoning follow these preventive tips:
 
1.) Never heat your home with a gas stove /gas range.
 
2.) Never use a charcoal grill or a hibachi in your home.
 
3.) Never use a gas powered generator or a gas powered machine in the home or basement.
 
4.) Make sure all fuel burning appliances are properly installed and maintained by a certified technician.
 
5.) Never use a gas powered machine by an open window (fumes can seep into the home). Always clear exhaust pipes from automobiles and trucks during snowstorms.
 
6.) Make sure fireplace, chimneys and flues are checked and cleaned every year.
 
7.) Never sit in a car or leave it running in a closed garage.
 
8.) Install a carbon monoxide detector in your home and check it regularly to make sure the battery is working.
 
In the event you become ill from carbon monoxide poisoning move yourself to fresh air and call 911. Follow instructions from operator and await the help of a trained medical professional.
