At atmospheric pressures carbon dioxide (CO2) is a colourless, odourless and non–conductive gas capable of penetrating quickly and efficiently the area to be protected. Its density is approximately 50% greater than the density of air. CO2 is stored in high pressure cylinders as liquefied gas. CO2 has been used effectively for any years, not only in fire protection but also in other commercial applications.

Although the use of CO2 as a suppression agent declined with the introduction of halons, it is still widely used for fire protection. CO2 suppresses fires by physical means according to two main mechanisms. The first one is by decreasing the oxygen level inside the enclosure from 21% to a level below 15%. Most fires are unable to maintain combustion at such low levels. The second mechanism is by means of cooling and heat absorption.
