what use has a ABC fire extinguisher got?

An ABC fire extinguisher is versatile and can be used to combat three types of fires: Class A (ordinary combustibles like wood and paper), Class B (flammable liquids such as gasoline and oil), and Class C (electrical fires). It contains a dry chemical agent, usually monoammonium phosphate, which effectively smothers flames and interrupts the chemical reaction. This makes it suitable for use in homes, offices, and various industrial settings, providing comprehensive protection against common fire hazards.
