What is an ABC fire extinguisher used for?

An ABC fire extinguisher is specifically designed to combat a wide range of fire types, making it a versatile tool in fire safety. It can effectively extinguish fires caused by ordinary combustibles, such as trash, wood, and paper, which fall under Class A fires. Furthermore, it is also suitable for Class B fires involving flammable liquids and Class C fires that involve electrical equipment.

The ABC designation indicates that the extinguisher contains a dry chemical agent, typically monoammonium phosphate, which effectively interrupts the chemical reaction that fuels these various types of fires. Because of this broad applicability, an ABC fire extinguisher is commonly found in both residential and commercial settings, providing essential protection against multiple fire hazards.

Other options might limit the context or scope of the fire extinguisher's usage, focusing only on specific fire types, which does not accurately represent the capabilities of an ABC extinguisher.
