The influence of crystalline salt hydrates in a fire extinguishing powder composition on its specific effectiveness in extinguishing flammable liquids

The article presents the comparative evaluation of specific fire extinguishing efficiency of powder compositions containing crystalline hydrate salts as a gas-generating component. Thermodynamic calculations and experimental tests have shown a reduction in the consumption of powder compositions for extinguishing highly flammable liquids by at least 30% when hexahydrate of magnesium-ammonium phosphate MgNH4PO46H2O is used as a component of fire extinguishing powders. The research has shown the advantage of implementing fine particles of crystalline hydrates (d<10 µm) obtained during the controlled precipitation process compared to analogs manufactured by mechanical grinding (d < 100 µm). The authors declares no conflicts of interests.
