Why does co2 make an excellent fire extinguisher?

The carbon dioxide considered the best fire extinguisher to put off fires caused by burning of inflammable liquids such as petrol or oil because carbon dioxide stops the influence of oxygen because it decreases the oxygen present in that fire which leads to the fallout of fire.

Why co2 gas is an excellent fire extinguisher?

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.

Why is co2 an excellent fire extinguisher draw a diagram of fire extinguisher?

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. … Hence, it is an excellent fire extinguisher.

Why is CO2 used to extinguish fire class 6?

Complete answer:

Carbon dioxide gas is non inflammable. Carbon dioxide gas does not support combustion. It displaces oxygen so that oxygen cannot come in contact with fire. Thus, carbon dioxide gas stops the supply of oxygen thereby removing oxygen from the fire triangle.

What is a CO2 fire extinguisher?

Why carbon dioxide is the best fire extinguisher class 8?

The carbon dioxide considered the best fire extinguisher to put off fires caused by burning of inflammable liquids such as petrol or oil because carbon dioxide stops the influence of oxygen because it decreases the oxygen present in that fire which leads to the fallout of fire.

Why is CO2 used in fire extinguishers instead of nitrogen?

Originally Answered: Why is CO2 filled in a fire extinguisher rather than nitrogen? CO2 can be stored in the liquid state under pressure at ambient temperature, something nitrogen cannot do. Therefore a cylinder will hold a lot more CO2 than nitrogen.

When should a CO2 fire extinguisher not be used?

Dangers: CO2 extinguishers should not be used on fires involving solid materials, such as paper, wood and fabric, and also are not suitable for use on flammable gases. How it works: The CO2 works by cutting off the fire’s oxygen supply. This then smothers it and, as it does so, extinguishes the flames.
