What does a Blue Powder Extinguisher combat?

A Blue Powder Extinguisher, commonly known as an ABC extinguisher, is designed to combat a wide range of fire types including those caused by solid materials like wood and paper, flammable liquids, and flammable gases. The powder used in these extinguishers is typically made of sodium bicarbonate or ammonium phosphate, which effectively suppresses flames by creating a barrier between the fuel and the oxygen in the surrounding air.

This versatility makes the Blue Powder Extinguisher suitable for various environments, from homes to workplaces where different types of fires might occur. Therefore, it is capable of addressing not just one specific type of fire, but multiple types, resulting in it being classified as suitable for all the mentioned categories.
