General CO Information

Carbon Monoxide (CO) is a colorless, odorless, and tasteless

poison gas that can be fatal when inhaled. CO inhibits the

blood’s capacity to carry oxygen.

Possible Sources

CO can be produced when burning any fossil fuel: gasoline,

propane, natural gas, oil and wood. It can be produced by

any fuel-burning appliance that is malfunctioning, improp-

erly installed, or not ventilated correctly. Possible sources

include furnaces, gas ranges/stoves, gas clothes dryers,

water heaters, portable fuel burning space heaters, fire-

places, wood-burning stoves and certain swimming pool

heaters. Blocked chimneys or flues, back drafting and

changes in air pressure, corroded or disconnected vent

pipes, and a loose or cracked furnace exchanger can also

cause CO. Vehicles and other combustion engines running

in an attached garage and using a charcoal/gas grill or

hibachi in an enclosed area are all possible sources of CO.

The following conditions can result in transient CO situations:

Excessive spillage or reverse venting of fuel-burning appli-

ances caused by outdoor ambient conditions such as: Wind

direction and/or velocity, including high gusts of wind, 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 connections vibrating loose from clothes dryers,

furnaces, or water heaters, obstructions in, or unconvention-

al, 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 gasses near the ground, car idling in an open or

closed attached garage, or near a home.
