Purple K is used to put out what class of fires?

• A. Class A
• B. Class B
• C. Class B C or D
• D. Class C

Answer: (C)

Purple K is a dry chemical extinguishing agent that works by interrupting the chemical reactions occurring in the flame and by coating the fuel surface to prevent heat feedback. It is particularly effective on flammable-liquid fires and energized electrical fires, which makes it a common choice for Class B and Class C fires. In some cases and under certain guidelines, it can also be used on metal (Class D) fires, depending on the metal and local procedures. Therefore, the option that lists Class B, Class C, or Class D fires reflects its versatile use across those classes.
