A. Properties and Characteristics
of Carbon Monoxide
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. However, all occupants’ health should be
considered. Physical exertion accelerates the rate at
which the blood absorbs CO.
1. Carbon monoxide is a colorless, odorless and
tasteless gas. It is commonly referred to as CO.
. 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.
DO NOT rely on the use of smell or sight of
other gases to detect CO, because it diffuses
in the air much more rapidly than easily
detectable vapors (i.e., visible and aromatic
One or more of the following symptoms can signal
the adverse effect of CO ac cumulation:
1. Watering and itchy eyes
2. Flushed appearance
Inability to think coherently
Loss of physical coordination
Ringing in the ears
Tightness across the chest
B. What Makes Carbon Monoxide
Any time a material containing carbon burns such
as gasoline, natural gas, oil, propane, coal, or wood,
CO is produced.
Common sources of carbon monoxide are:
Internal combustion engines such as:
Open ﬂame devices such as:
Central heating plants
The order of the above list is generally
the sequence of appearance of symptoms.
However, the order of appearance may
change for different people.
C. How a Person is Affected by Carbon Monoxide
The symptoms of carbon monoxide poison-
ing may easily be mistaken for seasickness or
Carbon monoxide is absorbed by the lungs and reacts
with blood hemoglobin to form carboxyhemoglobin,
which reduces the oxygen carrying capacity of the
blood. The result is a lack of oxygen for the tissues
with the subsequent tissue death and, if exposure is
prolonged, death of the individual.
F. Treatment (Evaluate, Ventilate, Evacuate,
Investigate, Take Corrective Action)
D. Effects of Carbon Monoxide
Evaluate the situation and ventilate the area if
Carbon monoxide in high concentrations can be fatal
in a matter of minutes. Lower concentrations must not
be ignored because the effects of exposure to CO are
cumulative and can be just as lethal.
Evacuate the area and move affected person(s)
to a fresh air environment.
