Carbon Monoxide Poisoning and the Environment

Carbon monoxide, or CO, is a toxic gas that you cannot see or smell. It is found in exhaust from cars and trucks, lawn and construction equipment, airplanes, boats, and trains.

CO usually comes from sources in or near your home that are not properly maintained or vented. These sources include heating systems, water heaters, portable generators, and gas cooking ranges and appliances. CO from these sources can build up in a place that does not have a good flow of fresh air.
