Question

The component of air which is used to extinguish fire? ​

Answer 1

Explanation:

Sodium bicarbonate, regular or ordinary used on class B and C fires, was the first of the dry chemical agents developed. In the heat of a fire, it releases a cloud of carbon dioxide that smothers the fire. That is, the gas drives oxygen away from the fire, thus stopping the chemical reaction.

Answer 2

In fire extinguishers, carbon dioxide gas is stored under very high pressure. When carbon dioxide gas comes out of fire extinguishers, it is very cold. So it cools the fuel. To extinguish fire, carbon dioxide gas is frequently used in laboratories and kitchens.
