SOURCES OF CARBON MONOXIDE:
Home appliances used for cooking and heating are the most common
household Carbon Monoxide sources. Vehicles running in an attached
garage can also produce dangerous levels of CO. Burning any fossil fuel
including gasoline, propane, natural gas, oil, and wood can produce
Carbon Monoxide. It can be produced when any heating or cooking
appliance is not installed properly, vented correctly, or malfunctioning.
CO producing appliances include furnace, hot water heaters, gas range/
stove, gas dryer, fuel burning space heaters, generators, vehicles,
fi
re-
places, blocked chimney/vents and grills.
CONDITIONS WHICH CAN RESULT IN TEMPORARY CO SITUATIONS:
1.
Excessive spillage or reverse venting of fuel burning appliances
caused
by:
i.
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).
ii.
Negative pressure differential resulting from the use of
exhaust
fans.
iii.
Simultaneous operation of several fuel burning applica
tions competing for limited internal air.
iv.
Vent pipe connection vibrating loose from clothes dry
ers, furnaces, or water heaters.
v.
Obstructions in or unconventional vent pipe designs
which amplify the above situations.
