Carbon monoxide detector installation

Carbon monoxide is a leading cause of poisoning poisoning related injury and death. Proper carbon monoxide detector installation is important.

"Do's" for carbon monoxide detector installation:

  • Instal detectors in or close-to sleeping areas - where the sound of a CO alarm will readily wake up anyone sleeping.

  • Instal detectors on each level of a home.

  • Properly fasten and instal detectors following manufacturer instructions.

  • Carbon monoxide is approximately the same weight as air and will distribute throughout a room. A detector can be placed at any height in any acceptable location, as long as the alarm can be heard.

  • For extra protection, instal an additional carbon monoxide detector 10 to 15 feet (3 to 5 meters) from the furnace as well as other fuel burning heat sources.


"Do nots" for carbon monoxide detector installation:

To avoid damaging the detector and to minimize false alarms, do not instal carbon monoxide 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, etc.

  • 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, such as on or near an outlet in a high traffic area

  • where directly exposed to weather.
