If confronted with a "D" type fire, what would you use to extinguish it?

• A. Water
• B. Foam
• C. Silt or sand
• D. Dry chemical powder

Answer: (C)

For a "D" type fire, which involves combustible metals such as magnesium, titanium, aluminum, or lithium, the most suitable extinguishing agent is typically a material that can smother the fire and reduce its reaction with air. Silt or sand is effective in this scenario because it can smother the burning metal, cutting off its oxygen supply and preventing it from reacting with the air, which is crucial since many metal fires can burn intensely and react dangerously with water and other conventional extinguishing agents. Using water or foam on a "D" type fire is dangerous, as it can lead to violent reactions, including explosions, due to the metal's tendency to react with water. While dry chemical powders are often used for various fires, they may not be effective or safe for certain combustible metals, making silt or sand the more appropriate choice for containing and extinguishing a "D" type fire effectively.
