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. The alarm only
indicates the presence of carbon monoxide
gas at the sensor. Carbon monoxide gas
may be present in other areas.
This device is designed to protect individuals
from the acute effects of carbon monoxide
exposure. It will not fully safeguard individuals
with specific medical conditions. If in doubt
consult a medical practitioner. 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: Headaches, running nose,
sore eyes, nausea, vomiting, fatigue (often
described as ‘Flu-like’ symptoms).
•
Medium Exposure: Dizzyness, drowsyness
and vomiting.
•
Extreme Exposure: Unconsciousness, brain
damage and 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, charcoal grills. Other
possible sources that may prompt a CO alarm
include: fuel-fired appliances (eg, space
heater, furnace, water heater, range, oven,
clothes dryer), or other sources of combustion
(e.g., kerosene-burning stove or heater or gas log
fireplace) or internal combustion engines. 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. 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.
