Detailed Solution

The different methods of fire extinguishers are removing combustible substances, cutting the supply of air, cooling substance below its ignition temperature etc.
The method of extinguishing a fire involves several steps, which include removing the combustible substance, which is not possible in the case of igniting a building on fire, as the entire building is the combustible substance. Cooling the substance to below its ignition temperature is done with the help of water. But water works only in the case when paper or wood has caught fire. Fire in electrical equipment cannot be controlled with water conducts electricity. Cutting off the supply of air is done with the help of carbon dioxide gas, which is not a supporter of combustion.
