Abstract
The fire extinguisher is one of important fire safety equipments in Taiwan. The ABC powder fire extinguisher is a common fire safety equipment as it can extinguish different kinds of fire, such as papers, gasoline, electrical fire etc. The main constituents of ABC powders are ammonium dihydrogen phosphate and ammonium sulfate. The principal components of ammonium dihydrogen phosphate extinguishant are inspected according to the molybdenum-vanadium phosphate colorimetry in Section 4 and the volumetric method of quinoline in Section 3.1 of Taiwan's CNS 8450-1992 Method of Test for Fertilizers–Determination of Phosphorus Content, which major project is the determination of phosphorus content. The DSC was used in this study to inspect the ABC powder of fire extinguishers, the thermal decomposition values of constituents of powder were analyzed directly. Not to determine the phosphorus content indirectly is the key concept in this study. The results showed that the variation curves of ammonium dihydrogen phosphate and ammonium sulfate have their particularities, and they will not disturb each other.
