Amerex B441 10 lb. ABC Dry Chemical Extinguisher
ABC or Multi-Purpose Fire Extinguishers can be used on Class A, B, or C fires.
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 (anything that is plugged in).
ABC extinguishers utilize a specially fluidized and siliconized mono ammonium phosphate dry chemical. It chemically insulates Class A fires by melting at approximately 350°F and coats surface to which it is applied. It smothers and breaks the chain reaction of Class B fires and will not conduct electricity back to the operator.
