Notes
  • Your slide 6/11 is incorrect. You identify the extinguisher that is safe to use on most kinds of fire (oil, fats, paints, solvents, etc) as being Dry Powder. It is actually Dry Chemical. Dry Powder extinguishers are used ONLY for combustible metals (magnesium, aluminum, etc) and are specially designed for individual combustible metals. Just FYI if you ever use this PPT for a class.
