Use and Care Manual

24
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.
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.
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.
