Carbon monoxide is an extremely hazardous gas with no odor, color, or taste. Carbon monoxide can be formed from incomplete burning of gasoline, wood, kerosene or other fuels. Carbon monoxide is also found in cigarette smoke and vehicle exhaust. In homes, carbon monoxide can build up from poorly vented or malfunctioning heater, furnace, range or any appliance that runs on natural gas or oil.
Carbon monoxide is the most common cause of fatal poisonings.
Breathing automobile exhaust in a confined area can also result in carbon monoxide exposure. Enclosed garages can be quickly engulfed in CO if automobiles are left idling in side. Tobacco smoke also contains carbon monoxide. Have the professional check for proper ventilation and function. All homes should be equipped with carbon monoxide detectors.
