Question

Why is carbon dioxide commonly used in fire extinguishers?

Answer 1

Carbon dioxide is commonly used in fire extinguishers because carbon dioxide cuts off the direct contact of the fire with the oxygen and therefore extinguishes the fire.

Answer 2

Answer:

For fires involving electrical equipment and inflammable materials like petrol, carbon dioxide (CO2) is the best extinguisher. CO2, being heavier than oxygen, covers the fire like a blanket. Since the contact between the fuel and oxygen is cut off, the fire is controlled.
