What is Carbon Monoxide (CO)?
Carbon monoxide (CO) can be a deadly killer. This odorless, colorless gas, known by its chemical symbol CO, is the leading cause of accidental poisoning deaths in the United States each year. More than 1,500 people are killed annually and another 10,000 are injured. Carbon monoxide is also the leading cause of death in fire-related accidents. The deadly gas often overcomes victims before they can respond to warnings from a smoke. Another 3,000 to 4,000 people die of carbon monoxide poisoning in fire-related incidents each year.
