CO problems can be eliminated if these units are keep in good working condition with proper ventilation. One line of defense against CO poisoning is the carbon monoxide detector. CO detectors are devices that sound an alarm before CO levels reach hazardous levels. These devices can be battery powered, plugged-in, or hard wired for home use. Detectors should be placed close to the sleeping area in a location where the alarm can be heard from each bedroom.
Recommendations are to install a detector on each level of a multilevel home.
Detector should be placed at least 15 feet away from any fuel-burning appliance. When installing detector, make sure that all vents are unobstructed. Vaulted ceilings, gabled roofs, or other areas where dead air spaces may exist. Near ceiling fans, fresh air vents, or close to doors and windows that open to the outside. Detectors should be kept out of dusty, damp, humid, greasy, or dirty areas such as bathrooms, kitchens, or garages.
