- Fires are classified according to the type of fuel that is burning.
- If you use the wrong type of fire extinguisher on the wrong class of fire, you might make matters worse.
- It's very important to understand the four different fire (fuel) classifications…
Class A: Wood, paper, cloth, trash, plastics-solids that are not metals.
- Class B: Flammable liquids-gasoline, oil, grease, acetone. Includes flammable gases.
- Class C: Electrical-energized electrical equipment. As long as it's "plugged in."
- Class D: Metals-potassium, sodium, aluminum, magnesium. Requires Metal-X, foam, and other special extinguishing agents.
