CO2 CARBON DIOXIDE GAS
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 many years, not only in fire protection, but also in other commercial applications. Although the use of CO2 as extinguishing agent declined with the introduction of halons, it is still widely used for fire protection, especially since the Montreal Protocol was introduced (where bases were established to ban the use of Halon extinguisher).
