Type A Extinguishers - Solid fuels such as wood, paper, and plastic.
Type B Extinguishers - Flammable liquids such as grease, oil, and gasoline.
Type C Extinguishers - Energized Electrical fires such as extension cords, televisions, toasters. Once the item is unplugged, it than becomes a class A fire because it is no longer energized.
