1. INFORMATION ABOUT CARBON MONOXIDE
WHAT IS CARBON MONOXIDE?
Carbon monoxide (CO) is a highly toxic, invisible, odorless, and tasteless gas.
HOW IS CO GENERATED IN THE HOME?
Carbon monoxide is generated through incomplete combustion of fuel in various
home appliances. Faulty ventilation of furnaces, water heaters, fireplaces, wood
burning stoves, and space heaters are the major cause of high CO levels in the home.
Automobile and small engine exhaust are another source of CO.
HOW DOES CO POISON PEOPLE?
The human body depends on oxygen for the burning of fuel (food) to provide us
with the energy that allows our cells to live and function. Oxygen makes up
approximately 21% of the atmosphere and enters our lungs when we breathe. In our
lungs the oxygen combines with the hemoglobin in the blood (oxyhemoglobin), and is
carried in the blood stream throughout the body where it releases oxygen to the cells.
Carbon monoxide is dangerous because it bonds more tightly to the hemoglobin
(carboxyhemoglobin, COHb) than oxygen does. When CO combines with hemoglobin,
the hemoglobin's ability to combine with oxygen is lost. As the COHb concentration
rises, people become nauseous, unconscious, and ultimately die.
WHAT ARE THE SYMPTOMS OF CARBON MONOXIDE POISONING?
Many people often confuse carbon monoxide poisoning with the flu, the initial
symptoms being very similar. Different concentrations of CO over various lengths of
time cause different symptoms.
Many cases of carbon monoxide poisoning indicate that while the victims were
aware they were not well, they were also too disoriented to save themselves by either
calling for assistance or exiting the building. Also, due to size, small children and pets
are generally the first affected.
The following are the symptoms related to CARBON MONOXIDE POISONING.
Discuss them with all members of the household.
MILD EXPOSURE: Slight headache, nausea, vomiting, fatigue (often described
as “flu-like” symptoms)
MEDIUM EXPOSURE: Severe throbbing headache, drowsiness, confusion, fast
heart rate
EXTREME EXPOSURE: Unconsciousness, convulsions, cardiorespiratory failure,
brain damage, death

3. RECOMMENDED LOCATION OF ALARMS
The Consumer Products Safety Commission (CPSC) recommends the use of "at
least one CO alarm per household located outside each sleeping area." (See diagrams
"A" and “B”)
CO poisoning can happen anywhere in the home, but because most CO poisoning
cases occur while people are sleeping, the best location for the CO alarm is near the
sleeping area in the home. If there is more than one sleeping area in the home or on a
different floor, or if bedroom doors are closed during the night, you may need more than
one CO alarm.
Carbon monoxide at room temperature [68oF (20°C)] is slightly lighter than air
(density of 0.96716). However, at 32oF (0°C) carbon monoxide is much heavier than air
(density of 1.250). Because the density of CO at room temperature is close to the
density of air, it disperses easily through the air, similar to the scent of perfume
dispersing uniformly in all directions. This characteristic makes it possible for CO alarms
to be mounted anywhere in the room or hallway, including both wall and ceiling areas.
1. Locate the first alarm in the immediate area of the bedrooms. If more than one
sleeping area exists, locate additional alarms in each sleeping area.
2. Locate an alarm inside every room where someone sleeps with a door closed. The
closed door may prevent the alarm from waking the sleeper.
3. Locate an alarm on every level of the home. (See diagrams “A” and “B”)
