Carbon Monoxide

Carbon monoxide (CO) is a colorless, odorless and tasteless gas composed of one carbon and one oxygen atom. Carbon monoxide is a by-product of combustion processes. Although this gas is naturally present in the atmosphere, it can be formed to a significant extent from combustion products from the combustion of fossil fuels, vehicle exhausts and industrial processes, especially indoors.

Physical Properties
  • Colorless Carbon monoxide gas is colorless and therefore invisible to the eye.

  • Odorless: Carbon monoxide is an odorless gas, which makes it difficult to detect naturally by humans.

  • Tasteless: Carbon monoxide is a tasteless gas, so it cannot be tasted.

  • Density: Because it mixes with air, it behaves like air, but its density is slightly lighter than the density of air.


  • Carbon monoxide is a by-product of the combustion of fossil fuels.

  • The combustion of fossil fuel appliances (heaters, stoves, water heaters) indoors can cause the production of carbon monoxide from exhaust gases.


Areas of Use
  • Industrial Processes: Carbon monoxide can be used as an intermediate in various industrial processes, especially in metallurgy and chemical production.

  • Fuel: Carbon monoxide can also be used as a fuel in certain applications. For example, it can be used as an energy source in the reduction process of many metals.

  • Carbon monoxide is a poisonous gas. Inhaling high concentrations can have dangerous consequences by reducing oxygen carrying capacity.

  • Carbon monoxide detectors monitor carbon monoxide levels indoors, alerting people to potential dangers.

  • Proper ventilation and regular maintenance are important in reducing the danger of carbon monoxide.

  • It is important that fossil fuel appliances are used safely indoors and that exhaust gases are properly exhausted.

Taking the necessary precautions for the correct use and safety of carbon monoxide can help people reduce the risks from this toxic gas.
