Common sources of carbon monoxide are:
NOTICE
The boat owner should be aware that other fac-
tors may contribute to carbon monoxide accu-
mulation. The most common ones are listed in
this section. If a person is exhibiting carbon
monoxide-type symptoms (Refer to Section F
Symptoms), be sure to take the necessary pre-
cautions as prescribed later in this section.

Internal combustion engines.
Open flame devices such as:
a.
Cookingranges
b. Central heating plants
c. Space heaters
d. Water heaters
e. Fireplaces
NOTICE
Boats fueled by diesel have limited carbon mon-
oxide present in the exhaust in comparison to
gasolineengineexhaust. However,theboatowner
should still be aware of the causes and effects of
carbon monoxide which may occur in different
boating situations.

D. How a Person is Affected by Carbon
Monoxide
Carbon monoxide is absorbed by the lungs and reacts
withbloodhemoglobintoformcarboxyhemoglobin,which
reduces the oxygen carrying capacity of the blood. The
result is a lack of oxygen for the tissues with the subse-
quent tissue death and, if prolonged, death of the indi-
vidual.
A. Definition of Carbon Monoxide
1.
Carbon Monoxide: Carbon Monoxide (CO) is a gas
formedbythecombinationofonemoleculeofcarbon
and one molecule of oxygen. Chemists refer to it as
CO, its chemical formula, “C” for carbon and “O” for
oxygen.
E. Effects of Carbon Monoxide
Carbon monoxide in high concentrations can be fatal in a
matter of minutes. Lower concentrations must not be

lative and can be just as lethal.

COHb: Carboxyhemoglobin is the molecule formed
whenCarbonMonoxidecombineswithbloodinstead
of oxygen.
B. Properties and Characteristics of Carbon Mon-
oxide
Certain health related problems and age will increase the
effects of CO. People who smoke or are exposed to high
concentrations of cigarette smoke, consume alcohol or
have lung disorders or heart problems, are particularly
susceptible to an increase in the effects from CO. How-
ever, all occupants’health should be considered. Physi-
cal exertion accelerates the rate at which the blood ab-
sorbs CO.

2.
Carbon Monoxide is a colorless, odorless and taste-
less gas.
Its weight is about the same as air so it cannot be
expected to rise or fall like some other gases, but
will distribute itself throughout the space.

Symptoms
NOTICE
DO NOT rely on the use of smell or sight of other
gases to detect CO, because it diffuses in the
airmuchmorerapidlythaneasilydetectable(vis-
ible and smellable) gases.
One or more of the following symptoms can signal the
adverse effect of CO accumulation:

Watering and itchy eyes
Flushedappearance
Throbbingtemples
Inattentiveness
Inability to think coherently
Ringing in the ears
Tightness across the chest
Headache
C. What Makes Carbon Monoxide
Any time a material containing carbon burns such as
gasoline, natural gas, oil, propane, coal, or wood, CO is
produced.
