What is carbon monoxide?

Carbon monoxide (CO) is an odorless, colorless, poisonous gas created when any fuel is burned, such as:

  • Coal
  • Gasoline
  • Natural Gas
  • Oil
  • Propane
  • Tobacco (Yes, Even Tobacco)
  • Wood

When the amount of air available for combustion is limited, more CO is produced. Serious problems can develop when combustion by-products are not properly vented outside the house. A by-product of combustion, carbon monoxide can be a potential problem from a number of common sources:

  • Automobiles
  • Furnaces
  • Water Heaters
  • Fireplaces
  • Wood Stoves
  • Charcoal Grills
  • Gas Ranges
  • Space Heaters
  • Portable Generators
