Frequently Asked Questions
Where should a carbon monoxide detector be placed?
As carbon monoxide is lighter than air, you should install a carbon monoxide detector five feet from the ground or attach it to the ceiling. You should not store detectors close to a fireplace or an appliance that produces flames.
Why is my carbon monoxide detector going off?
If your carbon monoxide alarm sounds, the most likely cause is that it has detected carbon monoxide gas in the air. If this happens, it is important that you turn off any fuel-burning appliances and immediately ventilate your property. Other reasons why your alarm may go off include false alarms caused by flame-producing appliances.
