CO2 can be used as an extinguisher for fires involving electrical equipment and inflammable materials like petrol. It can be stored at high pressure as a liquid in cylinders. On releasing it from the cylinder, it expands enormously in volume and cools down. Thus, it not only forms a blanket around the fire but also brings down the temperature of the fuel. Hence, it is an excellent fire extinguisher.
