Class A extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics. The numerical rating on these types of extinguishers indicates the amount of water it holds and the amount of fire it can extinguish. Geometric symbol (green triangle)

Class B fires involve flammable or combustible liquids such as gasoline, kerosene, grease and oil. The numerical rating for class B extinguishers indicates the approximate number of square feet of fire it can extinguish. Geometric symbol (red square)

Class C fires involve electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use water to extinguish class C fires - the risk of electrical shock is far too great! Class C extinguishers do not have a numerical rating. The C classification means the extinguishing agent is non-conductive. Geometric symbol (blue circle)

Class D fire extinguishers are commonly found in a chemical laboratory. They are for fires that involve combustible metals, such as magnesium, titanium, potassium and sodium. These types of extinguishers also have no numerical rating, nor are they given a multi-purpose rating - they are designed for class D fires only. Geometric symbol (Yellow Decagon)

Class K fire extinguishers are for fires that involve cooking oils, trans-fats, or fats in cooking appliances and are typically found in restaurant and cafeteria kitchens. Geometric symbol (black hexagon)

Cut-off of oxygen supply or bringing down the temperature of the  burning mass below its ignition point, are the two  ways  of fire fighting.  Pouring water  on burning materials serves as (i) the evaporation of water to steam involves the absorption of  the latent heat of vaporization which it takes from the burning  mass and  thus  in turn  the burning material, by giving its  heat  to water  for steam formation, becomes collar i.e.  its  temperature lowers.  (ii)  Oxygen supply to burning  materials is  abstracted as  air  is  swept  away  from  its  neighborhood  due  to  steam
formation.
