• 

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 that they are unable to save 
themselves by either exiting the building or 
calling for assistance. Young children and 
household pets are usually the first affected.

 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.

Individuals with certain medical problems 
should consider using detection devices 
with lower COHb alarm capabilities and 
consider warning devices that provide 
audible and visual signals for carbon 
monoxide concentrations of under 30 ppm.

Installation of the apparatus should 
not be used as a substitute for proper 
installation, use and maintenance of fuel-
burning appliances, including appropriate 
ventilation and exhaust systems.

This apparatus 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 
your doctor.

CARBON MONOXIDE (CO) PRECAUTIONS

WHAT IS CARBON MONOXIDE?

Carbon Monoxide (CO) is an invisible, odourless, 
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 that are often sources 
of CO include oil or gas burning boilers, gas 
ovens, wood-burning fireplaces, and charcoal 
grills. If they are not properly maintained, are 
improperly ventilated or malfunction, CO levels 
can rise quickly. Additional sources include 
space and water heating, cooking, uncontrolled 
burning, tobacco smoking, internal combustion 
engine. 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. 
Nest Protect will alarm:
•  within 3 minutes at 300 ppm CO
•  within 40 minutes at 100 ppm CO
•  within 90 minutes at 50 ppm CO
Unit will not sound before 120 minutes of 
exposure at 30 ppm.

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.
