Question

8. Explain how CO, is able to control fires.​

Answer 1

Answer:

Explanation

Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.

Answer 2

Answer:

It helps in controlling fires in 2 ways..

Explanation:

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, CO2 is kept in the liquid form. When released, it expands enormouslyand cools down. This brings down the temperature of the fuel, which helps in controlling the fire.
