Answer:
The three essential requirements to produce fire are: 1) Fuel, 2) Air (Oxygen), 3) Heat for reaching the ignition temperature. Fire requires fuel, heat and oxygen to burn. ... Fire extinguishers apply an agent that will cool burning heat, smother fuel or remove oxygen so the fire cannot continue to burn. A portable fire extinguisher can quickly control a small fire if applied by an individual properly trained.
