Explanation

Carbon monoxide is an odorless, colorless gas that can be fatal, and it is essential to have working CO detectors in the home for early detection. CO can come from many sources, not just gas stoves or furnaces. CO detectors should be installed according to manufacturer guidelines; since CO is slightly lighter than air, they are often placed higher up on walls or on ceilings. In addition to visual inspections of vents and chimneys, regular professional maintenance of heating systems is critical in preventing CO buildup.
