Extinguishers are classified by a letter and number symbol. The number tells you how much of a fire the extinguisher can put out, and the letter tells you the type of fire it will extinguish.

  • Type A fires are of combustible solids like wood. On Type A extinguishers, the number relates to how many gallons of water the extinguisher is equal to for a Type A fire.
  • Type B fires are of flammable liquids like gasoline or oil. On Type B extinguishers, the number tells you the square footage of the fire the extinguisher can put out.
  • Type C fires are electrical fires. Type C extinguishers do not use numbers.
