Question

What fraction of fire class is using CO2?​

Answer 1

Answer:

CO

2

is a non-combustible gas and it is also non-supporter of combustion. It extinguishes fire in two ways:

1. Since it is heavier than oxygen, it covers the fire like a blanket and cuts off the contact between oxygen and fuel.

2. In cylinders, CO

2

is kept in the liquid form. When released, it expands enormously and cools down. This brings down the temperature of the fuel, which helps in controlling the fire.
