Carbon Monoxide Gas

Home

Carbon monoxide is an odorless, colorless and tasteless gas that can cause illness and even death. This poisonous gas is absorbed through the lungs into the bloodstream where it inhibits the blood’s capacity to transport oxygen throughout the body. It may build up in parts of your home such as in your kitchen, garage, basement or fireplace area. Improperly adjusted burners or poorly ventilated flues for any fuel burning appliance will accumulate carbon monoxide in the home.
