Carbon monoxide (CO) is a dangerous, poisonous gas that is colorless, odorless and tasteless. While you may be aware that smoke inhalation from fires is a common cause of CO poisoning, cigarette smoke and vehicle exhaust are the most common sources of CO exposure. Almost every flammable material produces some degree of CO when consumed. When you burn fuels such as gas, wood, charcoal, kerosene, propane, heating oil, coal and even natural gas, be sure to maintain proper ventilation so the carbon monoxide does not accumulate indoors and create a risk of illness or death.
Your fuel-burning equipment and appliances, such as wood burning stoves or fireplace inserts, fireplaces, space heaters, gas and charcoal grills, furnaces, water heaters, boilers or ranges produce CO gas. When natural gas equipment is installed, operated and properly maintained, CO gas is kept to safe levels.
