Proper placement of a carbon monoxide alarm is important. If you are installing only one carbon monoxide alarm, the recommendation is, it be located near the sleeping area, where it can wake you if you are asleep. An additional detector on every level and in every bedroom of a home provides extra protection.

Homeowners should remember not to install carbon monoxide alarms directly above or beside fuel-burning appliances, as appliances may emit a small amount of carbon monoxide upon start-up. A detector should not be placed within fifteen feet of heating or cooking appliances or in or near very humid areas such as bathrooms.

When considering where to place a carbon monoxide alarm keep in mind that although carbon monoxide is roughly the same weight as air (carbon monoxide's specific gravity is 0.9657, the specific gravity of air is 1.00), it may be contained in warm air coming from combustion appliances such as home heating equipment. If this is the case, carbon monoxide will rise with the warmer air.
