Carbon Monoxide Gas:
Know the Sources, Clues &
Signs of Exposure!
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.
