You should know about Carbon Monoxide.
Carbon monoxide, also known as "CO" by the chemical form, is considered to be a
highly dangerous poisonous gas, because it is colorless, odorless, tasteless and very
toxic. In general, biochemistry phenomena have shown that the presence of CO gas
inhibits the blood's capacity to transport oxygen throughout the body, which can even-
tually lead to brain damage. In any enclosed space (home, office), even a small accu-
mulation of CO gas can be quite dangerous. Although many products of combustion can

cause discomfort and adverse health effects, it is CO gas which presents the greatest
threat to life.
Carbon monoxide is produced by the incomplete combustion of fuels such as natural
gas, propane, heating oil, kerosene, coal, charcoal, gasoline, or wood. The incomplete
combustion of fuel can occur in any device which depends on burning for energy or
heat such as furnaces, boilers, room heaters, hot water heaters, stoves, grills, and in
any gasoline powered vehicle or engine (e.g., generator set, lawnmower). Tobacco
smoke also adds CO to the air you breathe. When properly installed and maintained,
your natural gas furnace and hot water heater do not pollute your air space with CO.
Natural gas is known as a "clean burning" fuel because under correct operating con-
ditions, the combustion products are water vapor and carbon dioxide (CO2), which is
not toxic. The products of combustion are exhausted from furnaces and water heaters
to the outside by means of a fuel duct or chimney. Correct operation of any burning
equipment requires two key conditions:
a. An adequate supply of air for complete combustion.
b. Proper ventilation of the products of combustion from the furnace through the
chimney, vent or duct to the outside.
Typical carbon monoxide gas problems are summarized here:
a. Equipment problems, due to defects, poor maintenance, damaged and cracked
heat exchangers.
b. Collapsed or blocked chimneys/flues, dislodged, disconnected or damaged vents.
c. Downdraft in chimneys or flues. This can be caused by very long or circuitous
flue runs, improper location of flue exhaust or wind conditions.
d. Improper installation or operation of equipment, chimney or vents.
e. Airtight homes with inadequate flow of fresh air for the combustion process.
f. Inadequate exhaust of space heaters or appliances.
g. Exhaust ventilation/fireplace competing for air supply.
Potential sources of carbon monoxide in your home or office include clogged chimney,
wood stove, wood or gas fireplace, automobile and garage, gas water heater, gas appli-
ance, gas or kerosene heater, gas or oil furnace, and cigarette smoke.
More information about conditions which result in transient CO
situations:
1. Excessive spillage or reverse venting of fuel burning appliances caused by:
a. 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).
