If you use storm windows, weather stripping and sealers to keep your home cozy and reduce fuel bills in winter, give special thought to indoor air quality. One possible pollutant or indoor air is carbon monoxide, produced by incomplete combustion of a solid, liquid or gaseous fuel.
Gas ranges, furnaces and automobiles are all possible sources.
While breathing small amounts won't kill you, it can make you sick. Some symptoms of chronic exposure include constant headaches, fatigue and sleepiness. If you always feel headachy and worn out after a weekend at home and then recover at work on Monday morning, check your winter ventilation system. Replace any rusted or damaged parts. If you are converting from one type of fuel to another, get a qualified technician to do the work.
