Carbon monoxide (CO) is a colorless, odorless, and highly poisonous gas produced by the incomplete combustion of carbon-containing fuels. Examples of sources include gasoline engines, furnaces, and stoves. The critical point to understand is the mechanism by which this toxic gas is created: burning fuel.
Understanding the sources of CO is crucial because exposure can lead to serious health problems, including death. Historically, inadequate ventilation with fuel-burning appliances has been a major cause of CO poisoning. Awareness of potential sources and proper maintenance of appliances are essential preventative measures.
