Which of the following is NOT a type of fire extinguisher?

• A. Class A
• B. Class E
• C. Class B
• D. Class C

Answer: (B)

Class E is not recognized as a standard classification for fire extinguishers. The classification system for fire extinguishers includes Class A, B, C, D, and K categories, each designated to address specific types of fires. Class A extinguishers are effective on ordinary combustible materials such as wood, paper, and textiles. Class B extinguishers are used for flammable liquids like gasoline, oil, and grease. Class C extinguishers are designed for fires involving electrical equipment. Class D extinguishers are meant for combustible metals, while Class K extinguishers are for kitchen fires involving cooking oils and fats. Since Class E is absent from this established classification system, it is the correct answer to the question regarding which option is not a type of fire extinguisher.
