What is carbon monoxide and its sources?
monoxide is a poisonous gas that is odorless, colorless,
tasteless and nonirritating. When it is breathed into
the body, it combines with the body’s blood and prevents
oxygen absorption. This interferes with the heart and
brain functions and can be fatal.
monoxide is produced by incomplete combustion of common
fuels, such as natural gas, propane, gasoline, and heating
oil. It is found in the exhaust fumes from motor vehicles
and malfunctioning heating equipment.
Preventing carbon monoxide poisoning:
operate vehicles in an enclosed area
vents and chimneys clear of debris
operate charcoal or gas grills in an enclosed area
not use a range, oven or clothes dryer for heating
for signs of equipment problems, such as soot or water
collecting near a burner vent. Natural gas and propane
should produce a clear blue flame – not a yellow or orange
