Answer:

Concept:

Wood, plastic, and paper are Class A Materials.

Explanation:

Ordinary flammable materials like cloth, wood, paper, rubber, and many types of polymers are involved in class A fires. A-rated extinguishers are made to put out fires involving these common flammable items.

Liquids that are flammable and combustible, like gasoline, alcohol, oil-based paints, and lacquers, are involved in class B fires. Extinguishers with a B grade are therefore made to put out flames involving flammable and combustible liquids.

Electrical equipment that is energised is involved in Class C fires. Extinguishers with a C rating are made to be used on fires involving electrical equipment that is electrified.

Combustible metals like sodium, titanium, and magnesium are involved in class D fires. D-rated extinguishers are used to put out fires involving flammable metals.
