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.
As Fire needs oxygen to burn, Carbon Dioxide Covers the fire like an blanket and cuts the contact of fire to the oxygen present in the air, So Fire stops burning. That is why Carbon Dioxide is Considere as the best Fire Extinguisher.

Carbon dioxide extinguishers work because carbon dioxide molecules are heavier than oxygen molecules. When the liquid carbon dioxide inside the extinguisher expands into a gas, the carbon dioxide pushes out any oxygen surrounding the fire. Without oxygen available to fuel the chemical reaction, the fire goes out quickly.

Why are fire extinguishers not suitable for chemical fires?
These extinguishers are not suitable for chemical or electrical fires since the liquid can conduct electricity and cause flammable agents to spread. Other extinguishers coat the fuel, forming a barrier between the flammable material and the oxygen in the surrounding air.
Why are carbon dioxide fire extinguishers dangerous in confined spaces?
Without oxygen available to fuel the chemical reaction, the fire goes out quickly. This property can also make them dangerous in confined spaces since the carbon dioxide also pushes out any oxygen that the user needs to breathe. In addition to carbon dioxide extinguishers, fire extinguishers use other methods to put out fires.
What are the different types of fire extinguishers?
In addition to carbon dioxide extinguishers, fire extinguishers use other methods to put out fires. Wet extinguishers spray a liquid that absorbs heat, similar to pouring water on a campfire. These extinguishers are not suitable for chemical or electrical fires since the liquid can conduct electricity and cause flammable agents to spread.
