Dry Powder Extinguishing Agent is listed for which material classes?

Explanation:
Dry chemical powder extinguishing agents are versatile because they interrupt the chemical reactions in the flame and create a barrier that helps separate fuel from oxygen, while also cooling the surface. This makes them effective on the three most common fire types: ordinary combustibles (Class A), flammable liquids (Class B), and energized electrical equipment (Class C). Therefore, they are listed for Class A, B, and C fires. They aren’t suitable for Class D metal fires, which require specialized metal-fire powders tailored to the specific metal involved. That’s why the best choice includes A, B, and C.
