Beware the Silent Killer
What is carbon monoxide and why is it called the "silent killer"?
Carbon monoxide (CO) is an odorless, colorless and tasteless gas that
is slightly lighter than air. CO can easily be absorbed into the bloodstream
and inhibit the blood’s ability to carry oxygen, leading to a potentially
fatal condition called carbon monoxide poisoning. CO is often referred
to as the silent killer because CO poisoning may occur without the victim
being aware that anything is wrong.
How is carbon monoxide produced?
Carbon monoxide is produced by the incomplete combustion of any fuel
that contains carbon. This includes gasoline, natural gas, oil and propane,
as well as coal and wood products. Sources of CO include gas- and oil-burning
appliances like furnaces, dryers, water heaters, ovens, wood burning stoves,
charcoal grills, gas powered forklifts and automobiles.
What are the symptoms of carbon monoxide exposure/poisoning?
Symptoms of low-level CO poisoning include headaches, nausea, weakness,
dizziness and confusion. They are similar to what a person might exhibit
if affected by the flu or other common illnesses. CO exposure causes a
victim’s blood pressure to rise in an attempt to get more oxygen to the
body. As a result, the skin may take on a reddish color. Longer CO exposure
can cause lack of coordination, chest pain, vomiting and loss of consciousness.
If exposed to CO long enough, coma and death can occur.
Where should CO
monitors be placed?
The Consumer Product Safety Commission (CPSC) recommends installing at
least one carbon monoxide alarm with an audible warning signal near the
sleeping areas in a home. If a home has multiple levels, more detectors
might be necessary.
How can CO exposure and poisoning be prevented?
To protect against CO exposure and poisoning:
- Install CO
monitors at work and at home.
- Educate yourself and your family on the effects of CO poisoning.
- Check gas appliances periodically for proper operation and venting.
- Ensure chimneys, flues and vents are clear of debris.
- Do not use unvented gas and wood stoves or charcoal grills indoors.
- Do not permit automobiles or other gas-powered equipment to run indoors
without proper exhaust ventilation.
What should be done if CO exposure or poisoning is suspected?
If a CO detector activates and you are experiencing any of the symptoms
of CO poisoning, leave the house and seek assistance from a medical professional.
