Carbon monoxide is an odorless, colorless and toxic gas.
Because it is impossible to see, taste or smell the toxic fumes, carbon monoxide can kill you before you are aware it is in your home. At lower levels of exposure, carbon monoxide causes mild effects that are often mistaken for the flu. These symptoms include headaches, dizziness, disorientation, nausea and fatigue. The effects of carbon monoxide exposure can vary greatly from person to person depending on age, overall health and the concentration and length of exposure. Everyone is at risk for carbon monoxide poisoning.
