A multipurpose extinguisher suitable for liquids, gases, and ordinary combustibles is labeled which of the following?

• A. A
• B. BC
• C. ABC
• D. D

Answer: (C)

Fire extinguisher labels show which types of fires they can fight. Class A fires are ordinary combustibles like wood and paper; Class B fires involve flammable liquids (and gases in many classifications); Class C fires are energized electrical equipment. A multipurpose extinguisher labeled for all three classes can handle ordinary combustibles, liquids or gases, and electrical fires. Since the scenario asks for capability on liquids, gases, and ordinary combustibles, the extinguisher that covers A, B, and C is the right choice. Labels that cover only one or two classes won’t address all three, and a metal-burning extinguisher (Class D) is for a different hazard altogether.
