What does a Class ABC fire extinguisher protect against?

• A. Class A ordinary combustibles
• B. Class A, B, and C fires
• C. Class B flammable liquids
• D. Class C electrical fires

Answer: (B)

An extinguisher rated ABC is a multipurpose tool designed to handle three common fire types: ordinary combustibles like wood and paper, flammable liquids such as gasoline or solvents, and energized electrical equipment. It uses a dry chemical powder that interrupts the chemical reactions occurring in the flame and coats surfaces to separate the fuel from the oxygen, helping to smother the fire and prevent reignition. Because it covers these three categories, it’s the best option when a single extinguisher might confront more than one fire hazard. It’s not intended for metal fires (Class D) or cooking oils (Class K), which require specialized extinguishers. If dealing with an electrical fire, turn off power first if it’s safe to do so.
