Explain the classes of fires and the method of extinguishing each.

Explanation should include identifying the location of the fire extinguisher and comparing the following:

• Class A fires consist of ordinary combustibles (e.g., wood, paper, trash) and are extinguished with water.
• Class B fires consist of flammable liquids (e.g., oil, gasoline) and are extinguished by smothering.
• Class C fires consist of electrical equipment (i.e., anything plugged into an electrical outlet) and are extinguished with non-conductive extinguishing agents (e.g., carbon dioxide).
• Class D fires consist of combustible metals (e.g., magnesium, titanium) and are extinguished with dry powder extinguishers.
• Class K fires consist of grease (e.g., cooking oils, animal fat) and are extinguished with a wet chemical extinguishing agent (e.g., potassium carbonate, potassium acetate, or potassium citrate) which reacts with the grease/oils to form a soapy foam layer.
