carbon monoxide sensor mounting height

Where should I install carbon monoxide alarms and in ...

Although there is a myth that carbon monoxide is heavier than air, it's actually slightly lighter than air and it diffuses throughout the room/house evenly. According to a peer-reviewed study published in the Journal of Emergency Medicine, the installation height of your CO alarm doesn't affect the alarm's performance. This means you do NOT need to install alarms near the floor. When you ...

Where should I place a carbon monoxide detector? | US EPA

· Where Should I Place a Carbon Monoxide Detector? Because carbon monoxide is slightly lighter than air and also because it may be found with warm, rising air, detectors should be placed on a wall about 5 feet above the floor. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance. Keep the detector out of the way of pets and children. Each floor needs a separate detector. If you are getting a single carbon monoxide ...

PROPER PLACEMENT OF CARBON MONOXIDE

When considering where to place a carbon monoxide detector, keep in mind that although carbon monoxide is roughly the same weight as air (carbon monoxide's specific gravity is , as stated by the EPA; the National Resource Council lists the specific gravity of air as one), it may be contained in warm air coming from combustion appliances such as home heating equipment. If this is the case ...

At What Height Should Sensors be Mounted?

The sensor mounting height depends the type of application and on the density of the gas relative to air. Heavier than air gases should typically be detected 6 inches from the floor, lighter than air gas sensors should typically be placed on or near the ceiling, and gases which have a density close to that of air should have sensors installed in the "breathing zone" 4 - 6 feet from the floor. The breathing zone …
