Fire extinguishers for combustible metals are classified under which category?

• A. A
• B. B
• C. C
• D. D

Answer: (D)

Fire extinguishers for combustible metals are classified under category D. This classification is specifically designed for fires involving combustible metals such as magnesium, sodium, titanium, and potassium, which require unique extinguishing agents due to their reactive nature. Standard extinguishing agents, like water or foam, may react violently with these metals, which is why specialized agents, such as dry powder extinguishing agents, are used to suppress these types of fires. Choices for categories A, B, and C pertain to different types of fires: A covers fires involving ordinary combustibles (like wood or cloth), B is for flammable liquids (such as gasoline or oil), and C is designated for electrical fires. Each class requires distinct firefighting methods and materials, making it crucial to correctly identify the type of fire for effective response. Category D specifically addresses the requirements for safely managing fires involving combustible metals, highlighting the specialized techniques and materials required for successful fire suppression in these scenarios.
