Question

Explain how CO2 is able to control fires?​

Answer 1

• Carbon dioxide puts out fires by displacing oxygen and removing the oxygen element from the fire triangle.

• As the carbon dioxide leaves the extinguisher, it is very cold, so it cools the gasoline as well.

• CO2s may be unsuccessful at extinguishing Class A flames because they cannot displace enough oxygen to put the fire out completely.

• Smoldering and re-igniting of Class A materials is also possible.

• CO2s are commonly found in labs, mechanical rooms, kitchens, and spaces where flammable liquids are stored.

• Every five years, all CO2 extinguishers at USC are hydrostatically tested and recharged.

Answer 2

Answer:

• Carbondioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangles.
• Carbon dioxide is very cold as it comes out of the extinguisher, so it cools the fuel.
• As carbondioxide is heavier than oxygen : When it sprayed ,it cuts the supply of oxygen.
• Carbon dioxide doesn't harm elctrical equipment :if water is sprayed on electrical equipment, it damages it can causes  short circuit.
• In fire extinguishers,carbondioxide  is in liquid form under pressure and it can work on small flamable lquid.
