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 boiler, 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.
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.

MONOXIDE ALARMS
• Keep carbon monoxide alarm at least 1.5 m
(5 ft) away from any cooking appliance
including stovetop, oven, microwave, etc.
• This alarm should not be installed in locations
where the temperature is below 4 °C (40 °F)
or above 38 °C (100 °F)
• In a enclosed space (for example in a cupboard
or behind a curtain)
• Where it can be obstructed (for example
by furniture)
• Directly above a sink
• Next to a door or window
• Next to an extractor fan
• Next to an air vent or other similar
ventilation openings
• Where dirt and dust may block the sensor
