Carbon monoxide is a colorless, odorless, and tasteless gas that is produced by incomplete combustion of fuel-burning appliances and equipment, such as furnaces, water heaters, and generators.

Early diagnosis and appropriate treatment can help prevent complications and improve the chances of a full recovery. By taking these steps, you can help protect yourself and your family from the dangers of carbon monoxide poisoning.

 

What is Carbon Monoxide?

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is formed when carbon-containing materials such as wood, oil, or gas are burned with insufficient oxygen. It is a highly toxic gas that can be lethal when inhaled in high concentrations. Carbon monoxide is dangerous because it binds strongly to hemoglobin in the blood, preventing the delivery of oxygen to the body's cells and tissues. Symptoms of carbon monoxide poisoning can include headache, nausea, dizziness, confusion, and ultimately death. 

Carbon monoxide is also a major contributor to air pollution and is produced by cars, trucks, and other vehicles, as well as industrial processes and natural sources such as wildfires. It is important to have carbon monoxide detectors in homes and other enclosed spaces to ensure early detection of any leaks.
