Not all fires are the same. Different fuels create different fires and require
different types of fire extinguishing agents.
Class A fires are fires in ordinary combustibles such as wood, paper, cloth,
trash, and plastics.
Class B fires are fires in flammable liquids such as gasoline, petroleum oil,
and paint. Class B fires also include flammable gases such as propane and butane.
Class B fires do not include fires involving cooking oils and grease.
Class C fires are fires involving energized electrical equipment such as
motors, transformers, and appliances. Remove the power and the Class C fire
becomes one of the other classes of fire.
Class D fires are fires in combustible metals such as potassium, sodium,
aluminum, and magnesium.
