CARBON
MONOXIDE
(CO)
PRECAUTIONS
WHAT
IS
CARBON
MONOXIDE?
Carbon
Monoxide
(CO)
is an invisible, odorless,
tasteless
gas produced when
fuels
do
not
burn
completely, or are exposed
to
heat (usually fire).
These fuels include: wood, coal, charcoal, oil
natural
gas, gasoline, kerosene, and propane.
Common
appliances are
often
sources
of
CO
such as oil or gas burning furnaces, gas
ovens, wood-burning fireplaces, and charcoal
grills.
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. Electrical appliances
typically
do
not
produce
CO.
The
Nest
Protect
CO
sensor meets
the
alarm response
time
requirements
of
the
American National Standard
ANSI/UL 2034.
Standard alarm
times
are as follows:
•
At
70ppm,
the
unit
must
alarm
within
60-240 minutes.
•
At
150ppm,
the
unit
must
alarm
within
10-50
minutes.
•
At 40ppm,
the
unit
must
alarm
within
4
to
15
minutes.
A
WARNING
This carbon monoxide alarm is designed
to
detect
carbon monoxide from any
source
of
combustion.
It
is
NOT
designed
to
detect
any other gas.
A
CAUTION
The alarm only indicates
the
presence
of
carbon monoxide gas
at
the
sensor.
Carbon
monoxide gas may
be
present
in
other
areas.
Individuals with certain medical problems should
consider using detection devices with lower
COHb
alarming capabilities and consider warning
devices which provide audible and visual signals for
carbon monoxide concentrations under
30ppm.
SYMPTOMS
OF
CO
POISONING
The following
symptoms
are related
to
CARBON
MONOXIDE
POISONING
and are
to
be discussed
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, death.
·Many
cases
of
reported
CARBON
MONOXIDE
POISONING
indicate
that
while
victims
are aware
they
are
not
well,
they
become
so disoriented
they
are unable
to
save
themselves by
either
exiting
the
building or
calling
for
assistance. Young children and
household
pets
are
typically
the
first
affected.
