Check forced air fans for proper installation and correct air flow of flue gases.Check furnace filters and filtering systems for dirt or blockages.Check furnace connections to flue pipes, chimneys, and venting systems outside of the home for signs of corrosion, blockages, rust, gaps, or holes.Measure the concentration of CO in the flue gases.Where should I look for sources of Carbon Monoxide in my home?Īn improperly installed or malfunctioning forced air furnace could be the source of CO and should be carefully inspected by a professional. In addition to installing carbon monoxide detectors, have a qualified professional check all fuel-burning appliances, furnaces, venting, and chimney systems at least once a year or as recommended by the manufacturer. The manufacturers of First Alert Carbon Monoxide Detectors make such a model, as well as a plug-in detector and a hardwired AC model with battery back-up. For an extra margin of safety, chose a self-powered, extra-sensitive unit that responds to lower levels of carbon monoxide and protects even during a power outage. Remember, a carbon monoxide detector is a purchase that could help save your life. A detector on every level and in every bedroom provides extra protection. The Consumer Product Safety Commission (CPSC) recommends installing at least one carbon monoxide detector with an audible alarm near the sleeping area. How can I protect myself and my family from carbon monoxide poisoning? But energy-efficient insulation meant to keep warm air in during winter months and cool air in during summer months could cause carbon monoxide to be trapped inside.įurnace heat exchangers can crack, vents and chimneys can become blocked, disconnected, or corroded inadequate air supply for combustion appliances can cause conditions known as down drafting or reverse stacking, which forces CO contaminated air back into the home. If a home is vented properly and is free from appliance malfunctions, air pressure fluctuations, or airway, venting, or chimney blockages, carbon monoxide will most likely be safely vented to the outside. Fumes from automobiles also contain carbon monoxide and can enter a home through walls or doorways if a car is left running in an attached garage.Īll of these sources can contribute to a CO problem in the home. It is produced by common home appliances, such as gas or oil furnaces, clothes dryers, ranges, ovens, water heaters or unvented space heaters, fireplaces, charcoal grills, and wood-burning stoves. *Source: Journal of American Medical Assn.Ĭarbon monoxide is a by-product of incomplete combustion, present whenever fuel is burned. As levels of COHb increase, vomiting, loss of consciousness, and eventually brain damage or death can result. Carboxyhemoglobin causes symptoms similar to the flu, such as headaches, fatigue, nausea, dizzy spells, confusion, and irritability. When CO is present in the air, it rapidly accumulates in the blood, forming a toxic compound known as carboxyhemoglobin (COHb). When breathed in, carbon monoxide bonds with hemoglobin in the blood, displacing the oxygen which cells need to function. The greater danger of carbon monoxide is its attraction to hemoglobin in the bloodstream. Medical experts believe, however, that individuals with greater oxygen requirements such as unborn babies, infants, children, senior citizens, and people with coronary or respiratory problems are at greater risk. Because you can't see, taste, or smell it, carbon monoxide can kill you before you know it's there.Įveryone is at risk for carbon monoxide poisoning. What is carbon monoxide and who is at risk?Ĭarbon monoxide (CO) is a colorless, odorless deadly gas. How long will a Carbon Monoxide detector last?.If the initial test for Carbon Monoxide is negative, could there still be a problem?.Where should I look for sources of Carbon Monoxide in my home?.How can I protect myself and my family from carbon monoxide poisoning?.What is carbon monoxide and who is at risk?.You can find answers about this "silent killer" by selecting the questions below. See below for more information.Ĭarbon monoxide is one of the leading causes of poisoning deaths in America. Here is a press release from the NC Office of State Fire Marshal concerning these alarm sounds. The detectors are also required to provide a separate alarm when they reach the end of their life. All rental property is required to have a working CO detector provided by the property owner or property management if the home is serviced by a fuel gas (i.e Natural Gas, LPG). Residents also need to be aware of new legislation concerning the detectors. Do you have a Carbon Monoxide "CO" detector? This device is just as important as a smoke alarm and many people don't have one.
