May be corrosive to iron and mild steels, aluminum, zinc and copper. Q. Monoammonium phosphate also called Mono ammonium phosphate or Ammonium dihydrogen phosphate, NH4•H2PO4, is formed when a solution of phosphoric acid is added to ammonia until the solution is distinctly acid. Hopefully someone will correct me if I am wrong, but I believe Class B-C extinguishers contain baking soda,sodium bicarbonate NaHCo3, non-corrosive; ABC extinguishers contain monoammonium phosphate (NH4H2PO4), which is corrosive in presence of moisture. When ammonia is added to phosphoric acid that hasn’t been heated, it produces monoammonium phosphate (11-52-0) or diammonium phosphate (18-46-0), depending on the ratio of the mixture. Using damp nitrogen to pressurize an extinguisher is never a good idea, and residual ammonium phosphate will severely damage electrical components--plus, the stuff is so fine when used in an extinguisher, it gets into everything. In addition to calcium levels, ammonia and phosphate levels should be monitored. ABC dry chemical is usually a mix of monoammonium phosphate and ammonium sulfate , the former being the active one.
