Which fire extinguisher is specifically designed for combustible metals?

• A. Class A Fire Extinguisher
• B. Class C Fire Extinguisher
• C. Class D Fire Extinguisher
• D. Class K Fire Extinguisher

Answer: (C)

The Class D Fire Extinguisher is specifically designed for extinguishing fires involving combustible metals, such as magnesium, titanium, and sodium. These types of fires require special agents, as typical extinguishing methods can exacerbate the situation. Class D extinguishers use dry powder agents that smother the fire and have unique properties that are effective at cooling and separating the fuel from the oxygen, which is essential for extinguishing metal fires. In most fire classifications, other classes address different types of materials, but Class D is unique in its focus on combustible metals. Other classes, like Class A, address ordinary combustibles like wood and paper; Class C is for electrical fires; and Class K is suitable for cooking oils and fats. Therefore, Class D is the only option directly concerned with fires arising from metals, making it the appropriate choice for this scenario.
