What is Carbon Monoxide ?
Carbon Monoxide (CO) is a colorless, odorless
deadly gas. Because you can not see, taste, or smell it, Carbon Monoxide
can kill you before you know it is there.
Who is at risk ?
Everyone is at risk for Carbon Monoxide
poisoning. Experts believe, however, that individuals with greater oxygen
requirements such as unborn babies, infants, children, senior citizens,
and people with coronary or respiratory problems are at greater risk.
Why is Carbon Monoxide so dangerous
?
The great danger of Carbon Monoxide is its
attraction to hemoglobin in the bloodstream. CO is breathed in through the
lungs and bonds with hemoglobin in the blood, displacing the oxygen cells
need to function. When CO is present in the air, it rapidly accumulates in
the blood, forming a toxic compound knows as caroxyhemoglobin (COHb).
Where does Carbon Monoxide come
from ?
Carbon Monoxide is a byproduct of combustion,
present whenever fuel is burned. It is produced by common home appliances,
such as gas or oil furnaces, refrigerators or clothes dryers, water
heaters, fireplaces, charcoal grills, gas ranges, wood burning stoves, and
space heaters. Fumes from automobiles also contain Carbon Monoxide and can
enter a home through walls or doorways if a car is left running in an
attached garage.
All of these sources can contribute to a CO
problem in the home. If a home is vented properly and is free from
appliance malfunctions, air pressure fluctuations or airway blockages,
Carbon Monoxide will most likely be safely vented to the outside. But in
today's energy efficient homes this is frequently not the case. Insulation
meant to keep warm air in during winter months can trap CO polluted air in
a home year round. Furnace heat exchangers can crack, vents can become
blocked, inadequate air supply for combustion appliances can cause
conditions knows as backdrafting or reverse stacking, which force
contaminated air back into the home.
How can I protect myself and my
family from CO poisoning ?
The Consumer Product Safety Commission (CPSC)
recommends installing at least one Carbon Monoxide detector per household,
near the sleeping area. A second detector near the home's heat source
provides extra protection. Choose an Underwriters Laboratories (UL) listed
detector that sounds an audible alarm. First Alert, the leading name in
home safety, manufactures a UL listed, battery operated Carbon Monoxide
detector that continues to protect even in the event of a power outage.
The First Alert model uses patented biomimetic technology, which simulates
the body's response to CO and will not respond to other gases. A hard
wired AC model with battery backup is also available.
