Amerex B424-15267

The Amerex B424 5 LB Monoammonium Phosphate based fire extinguisher is designed for use in combating Class A (trash, wood, and paper), B (liquids and gases), and C (electrical fires) type fires. ABC or multi-purpose 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.
