Is Carbon Monoxide Heavier Than Air?

Carbon Monoxide, CO, is a dangerous colorless, tasteless, and odorless gas produced by incomplete fossil fuel combustion. It can poison people when it is inhaled in high concentrations, leading to symptoms such as headache, dizziness, nauseousness and sometimes death. Carbon Monoxide poisoning occurs when carbon monoxide bonds with hemoglobin in the blood, displacing oxygen and depriving the body of vital energy. This can happen in many ways, from malfunctioning gas water heaters or furnaces, faulty wood stoves and fireplaces, and using gasoline-powered tools and equipment in confined spaces without adequate ventilation, such as auto shops or ice rinks.

Most sources of carbon is carbon monoxide heavier than air, such as gas furnaces, wood burning stoves and fireplaces, and kerosene heaters, are designed to vent gases outdoors through chimneys or vent pipes. However, these can be blocked by snow or bird nests, allowing carbon monoxide to backdraft into the home.

Is Carbon Monoxide Heavier Than Air

Because carbon monoxide is slightly lighter than air, many homeowners incorrectly assume that CO detectors should be placed on the ceiling. In fact, the height of a carbon monoxide detector does not make much difference in its effectiveness and it can be placed at any location where a manufacturer recommends it. It is important to follow the manufacturer’s recommendations, though. Different home layouts and types of carbon monoxide leaks may require different placement locations to ensure optimal protection. However, it’s always best to ensure that you have a CO detector in every sleeping area and hallways leading to bedrooms on each floor of your house.
