What Is Carbon Monoxide and Why Is It Dangerous?
Carbon monoxide is a colorless, odorless gas that can build up indoors when fuel-burning appliances, generators, or heating systems do not vent properly. Because it cannot be seen or smelled, people may be exposed without realizing there is a problem.
When inhaled, carbon monoxide reduces the body’s ability to carry oxygen through the bloodstream. Symptoms can include headaches, dizziness, weakness, nausea, confusion, and loss of consciousness. High concentrations can quickly become life-threatening.
Carbon monoxide detectors are designed to alert occupants when dangerous levels are present. Regular maintenance of heating equipment, appliances, and ventilation systems can help reduce the risk of exposure in homes and other buildings.
