By Mayo Clinic staffCarbon monoxide is a colorless, odorless and tasteless gas. But the danger it poses is real. Carbon monoxide replaces oxygen in your blood — and the consequences can be fatal. In the U.S., more people die each year of exposure to carbon monoxide than of any other type of poison.
Carbon monoxide is produced by appliances and other devices that burn gas, petroleum products, wood and other fuels. Sometimes carbon monoxide can accumulate to dangerous levels in your car, home or other poorly ventilated areas.
The signs of carbon monoxide poisoning can be subtle — but, simple precautions can save your life.
