This could save thousands of lives.

When ampoule is thrown at the fires the chemical will disperse over the burning area. At the same time, the extinguishing chemicals would generate ammonium gas. Water evaporation would cool down the temperature of combustibles (cooling effectiveness) while ammonium gas would create a fire retardation effect that restrains the burning chain reaction. At the same time, one of the main ingredients for SAT119 and carbon dioxide produced by heat would suffocate oxygen and restrain combustibles from burning (cutting oxygen).
