  • Fire extinguishers are classified according to a particular fire type and are given the same letter and symbol classification as that of the fire.
  • Type A – combustible wood, cloth, paper, rubber, and plastics.
  • Type B – flammable liquids, oil, grease, and paint thinners.
  • Type C – energized electrical equipment
  • Type D – combustible metals (Mg, Ti, Na, Li, K)
  • Multipurpose Extinguishers are effective against types A, B, and C fires
  • To effectively operate an extinguisher, think P-A-S-S
  • P — pull the pin
  • A– aim the hose and the base of the fire
  • S – squeeze the handle
  • S – sweep the hose back and forth
    • Never use water on a Type B fire.  These liquids float on water and, thus, water can spread the burning liquid.  Water makes hot grease splatter, and can result in burns.  Cover the burning grease with sand, baking soda, or with the metal lid of the frying pan.
    • Never use water on a Type C fire.  Water can cause a severe electric shock
