Fire can be extinguished in three ways:

Remove the Fuel

• The fuel is a food for fire. So, when a fire starts all the combustible materials should be removed so that the fire does not spread.

Remove the Heat

• The most common fire extinguisher is water, but it works for ordinary fires.
• Water is used to remove heat from a burning substance and to make it too cool to burn further.

Cut off the Air Supply

• For fires involving electrical equipment and inflammable materials like petrol, carbon dioxide is the best extinguisher.
