CHAPTER 5: What You Need To Know About CO

What is CO?

CO is an invisible, odorless, tasteless gas
produced when fossil fuels do not burn
completely, or are exposed to heat (usually fire).
Electrical appliances typically do not
produce CO.
These fuels include: Wood, coal, charcoal, oil,
natural gas, gasoline, kerosene, and propane.
Common appliances are often sources of CO. If
they are not properly maintained, are improperly
ventilated, or malfunction, CO levels can rise
quickly. CO is a real danger now that homes are
more energy efficient. “Air-tight” homes with
added insulation, sealed windows, and other
weatherproofing can “trap” CO inside.

Symptoms of CO Poisoning

These symptoms are related to CO POISONING
and should be discussed with ALL household
members.
Mild Exposure Slight headache, nausea,
vomiting, fatigue (“flu-like” symptoms).
Medium Exposure Throbbing headache,
drowsiness, confusion, fast heart rate.
Extreme Exposure Convulsions,
unconsciousness, heart and lung failure.
Exposure to Carbon Monoxide can cause brain
damage, death.
CAUTION!

Some individuals are more sensitive to CO

than others, including people with cardiac or

respiratory problems, infants, unborn

babies, pregnant mothers, or elderly people

can be more quickly and severely affected

by CO. Members of sensitive populations

should consult their doctors for advice on

taking additional precautions.

Finding the Source of CO

After an Alarm

Carbon monoxide is an odorless, invisible gas,
which often makes it difficult to locate the source
of CO after an alarm. These are a few of the
factors that can make it difficult to locate sources
of CO:
• House well ventilated before the
investigator arrives.
• Problem caused by “backdrafting.”
• Transient CO problem caused by
special circumstances.
