Multipurpose dry chemical Agent is associated with which class?

• A. Class B
• B. Class D
• C. Class A
• D. Class A and B

Answer: (C)

Multipurpose dry chemical agents are rated ABC, meaning they work on fires involving ordinary combustibles (Class A), flammable liquids (Class B), and energized electrical equipment (Class C). This broad capability is why they’re described as multipurpose. Among the given choices, the option that mentions both Class A and Class B best reflects this broader applicability; however, the full ABC rating also covers Class C, so the ideal, complete capability includes all three classes. Class B alone addresses only flammable liquids, Class D is for metal fires, and Class A alone covers only ordinary combustibles.
