Carbon dioxide (CO2) is a colourless, odourless, electrically non-conductive gas that is highly efficient. Extinguishing agent CO2 has been used for more than 80 years and was the first gaseous agent used for fire suppression. It can be used for local application and total flooding systems and is suited to a wide range of applications and hazards, CO2 has a high rate of expansion enabling rapid fire suppression and provides a heavy blanket of gas that reduces the oxygen level to a point where combustion cannot occur.
