What are the 3 principles of extinguishing a fire?

The basic methods for extinguishing a fire are to suffocate it by ensuring that it cannot have access to oxygen, to cool it with a liquid such as water which reduces the heat or finally to remove the fuel or oxygen source, effectively removing one of the three elements of fire.

What principle should be used for fire extinguisher?

Essentially, fire extinguishers put out fire by taking away one or more elements of the fire triangle/tetrahedron. Fire safety, at its most basic, is based upon the principle of keeping fuel sources and ignition sources separate.

What process Burns?

Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Class A: freely burning, combustible solid materials such as wood or paper. Class B: flammable liquid or gas. Class C: energized electrical fire (energized electrical source serves as the ignitor of a class A or B fire – if electrical source is removed, it is no longer a class C fire)
