What does an ABC rating indicate on an extinguisher?

An ABC rating shows what kinds of fires the extinguisher is designed to fight. Class A fires involve ordinary combustibles like wood, paper, and cloth; Class B fires involve flammable liquids such as gasoline or oil; Class C fires involve energized electrical equipment. So an extinguisher labeled with ABC is suitable for all three types of fires, making it a versatile, multipurpose option. It isn’t intended for Class D metal fires, nor is it limited to electrical fires alone. And yes, there is a rating that communicates its effectiveness across these classes, not a blank or no-rating label.
