The Center for Disease Control and Prevention defines carbon monoxide as "an odourless, colourless gas. It is produced any time a fossil fuel is burned and it can cause sudden illness and death."
The most common symptoms of CO poisoning are headache, dizziness, weakness, nausea, vomiting, chest pain, and confusion. High levels of CO inhalation can cause death. CO poisoning can also cause you to pass out and fall into the water and drown. A person who is sleeping or intoxicated can die from CO poisoning before ever having symptoms.
