What types of fires are dry chemical extinguishers used for?

Dry chemical extinguishers are versatile tools designed to combat a variety of fire types, specifically Class A, B, and C fires. Class A fires involve ordinary combustibles such as wood, paper, and cloth, which can be effectively extinguished using dry chemicals. Class B fires are those fueled by flammable liquids and gases, and the chemical agents in dry chemical extinguishers can rapidly suppress these types of fires as well. Lastly, Class C fires involve energized electrical equipment, and since dry chemical extinguishers are non-conductive, they are suitable for use in such situations.

This wide range of applications makes dry chemical extinguishers essential in many environments, as they can address multiple fire threats that may arise in both residential and commercial settings. The comprehensive effectiveness against all three classes distinguishes this option as the most appropriate answer.
