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
400ppm,
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.
