What is the best way to controlling fire?

The most common method to control a Class-A fire is to remove heat by spraying the burning solid fuels with water. Another control method would be to reduce the oxygen content in the immediate vicinity of the fire (i.e., "smother" the fire), such as by the introduction of an inert gas such as carbon dioxide.

Fire can be put out by taking away the fuel, stopping the supply of oxygen or by lowering down the temperature around the fuel, so that the fuel is not able to attain its flash point. Was this answer helpful?

How do we control fire short answer?

How we can control fire for Class 8?

⇒ 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. Carbon dioxide control fire by cutting the contact between the fuel and oxygen.

How can you control the fire class 8?

Generally, water is used to control fire. Water brings down the temperature of the combustible substance below its ignition temperature. The water vapour surrounds the combustible material, thus helping in cutting off the supply of air. So, that the fire is extinguished.

What is the best way to fight an electrical fire class 7?

Blowing on a burning matchstick or a candle removes the hot air around the flame, bringing down its temperature below the flash point. Sometimes water is sprayed on a fire. It absorbs heat from the burning fuel and lowers the temperature. It also cuts off the supply of oxygen, and therefore, the fire is extinguished.

What is fire class 9?

Fire is the product from a chemical reaction between oxygen in the atmosphere and some sort of fuel. Oxygen, fuel and heat are needed for fire to occur. This is known as the fire triangle. Combustion is when fuel reacts with oxygen to release heat energy.

Why should we control forest fire?

It not only deprives rare biodiversity species of their habitat but often goes out of control, setting even unintended territories on fire. Thus, it is essential to control a forest fire to prevent worse fires. Under certain conditions, the wind may spread a wildfire to dozens of miles away from the source of ignition.
