Carbon monoxide - CO

This page details information about carbon monoxide (CO) or carbonous oxide, appropriate detection means - carbon monoxide CO detector - and respiratory protective equipment (ABEK1NOCO20-P3 combined filter or self-contained breathing apparatus).

Carbon monoxide (CO) properties

Carbon monoxide (CO) or carbonous oxide is produced by incomplete combustion of organic matter (wood, fuel). As it is also released by engines exhausted gases (incomplete gasoline combustion), it is partially responsible for atmospheric pollution in big cities and car parks. It can also be found in the chemical industry in many substances synthesis or in the steel industry as a reducing agent to produce some catalysts.

Carbon monoxide effects on health

Carbon monoxide (CO) is a colorless and odorless gas that is not detectable without proper equipment. This gas is very toxic by inhalation (H331) and reduce the blood oxygen rate – that's why it is classified as a toxic asphyxiant. It is also very flammable with explosive limits set between 12 and 74 % volume, which explains its presence in many types of combustion. However its main hazard remains its toxicity.
