Class D extinguishers are specifically designed for which type of fire?

• A. Electrical equipment
• B. Flammable metals
• C. Ordinary combustibles
• D. Flammable liquids

Answer: (B)

Class D extinguishers are specifically designed for fires involving flammable metals such as magnesium, titanium, potassium, and sodium. These types of fires are unique because they do not respond to water or common fire suppression agents effectively; in fact, water can exacerbate the situation by causing the metals to ignite even more violently. Class D extinguishing agents are typically dry powders that smother the fire and absorb heat, thus stopping the combustion process. Understanding the characteristics of different fire classes is essential for safety in any environment where these materials are present, as using the wrong type of extinguisher on a Class D fire could lead to dangerous consequences. Thus, having the correct extinguisher type readily available and knowing when to use it is crucial for safe fire management in facilities that handle flammable metals.
