Sources of CO
CO comes from the incomplete combustion of ANY fuel,
such as wood, natural gas, propane, oil, coal, gasoline,
or kerosene. The following conditions can produce
dangerous transient levels of CO.
• Excessive spillage or reverse venting of fuel-burning
appliances caused by outdoor ambient conditions as
follows:
> Wind direction and/or velocity including high
gusts of wind or heavy air in the vent pipes
(cold/humid air with extended periods between
cycles).
> Negative pressure differential resulting from
the use of exhaust fans.
> Simultaneous operation of several fuel-
burning appliances competing for limited
internal air.
> Vent pipe connection vibrating loose from
clothes dryers, furnaces, or water heaters.
> Obstructions in the vent pipe or
unconventional vent pipe designs which can
amplify the above situations.
• Extended operation of unvented fuel-burning devices
(range, oven, fireplace, etc.).
• Temperature inversions which can trap exhaust gases
near the ground.
• Car idling in an open or closed attached garage or near
a home.
