Which fire class corresponds to combustible metals?

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

Answer: (C)

The correct classification for combustible metals is Class D. This class is specifically designated for fires involving combustible metals such as sodium, potassium, magnesium, and titanium. These materials can ignite and burn at extremely high temperatures, often producing hazardous reactions when combined with water or other firefighting agents. It's important to recognize that each class of fire has specific characteristics. Class A fires, for example, involve ordinary combustibles like wood, paper, and cloth, and are typically extinguished with water. Class B fires involve flammable liquids and gases, while Class C fires are those involving energized electrical equipment. Using the wrong extinguishing method on combustible metals can lead to dangerous situations, which is why the classification is critical for effective fire safety management.
