CO detector placement
Carbon monoxide is a leading cause of poisoning deaths and poisoning related injury. Proper CO detector
placement is essential to the proper functioning of the detector.
"Do's" for CO detector placement:
- Place detectors in or near sleeping areas - where the sound of an alarm will easily wake people up.
- Place detectors on each level of a residence.
- Place detectors as per manufacturer instructions.
- Carbon monoxide is roughly the same weight as air and over time distributes throughout a room. A detector
can be placed at any height in any acceptable location as long as the alarm can be heard.
- For added protection, place a carbon monoxide detector 10 to 15 feet (3 to 5 meters) from the furnace and
other fuel burning heat sources.
"Do nots" for CO detector placement:
To avoid damage to the detector and to reduce false alarms, do not place CO detectors:
- in unheated basements, attics or garages
- in areas of high humidity (bathrooms, showers, laundry areas)
- where they will be exposed to chemical solvents or cleaners, including hair spray, deodorant sprays,
- near vents, flues or chimneys
- within 6 feet (2 meters) of heating and cooking appliances (they may give off a small volume of carbon
monoxide when starting up which can trigger false alarms)
- near forced- or unforced-air ventilation openings
- within 6 feet (2 meters) of corners or areas where natural air circulation is low
- where they can be bumped and damaged
- where directly exposed to weather.
