What kind of fire would a Class D extinguisher be used for?

• A. Electrical fires
• B. Flammable liquids
• C. Combustible metals
• D. Cooking oils

Answer: (C)

A Class D fire extinguisher is specifically designed to combat fires that involve combustible metals. These types of materials can include magnesium, titanium, sodium, and potassium, all of which react violently and burn at extremely high temperatures. Traditional extinguishing agents, such as water or foam, can be ineffective or even dangerous when used on a Class D fire because they might intensify the reaction or spread the fire further. Class D extinguishing agents typically contain dry powder materials that act by smothering the flames and separating the fuel from the oxygen necessary for combustion. Understanding the specific use of Class D extinguishers is crucial for safely managing fires involving these hazardous materials. This knowledge is particularly important in industrial settings where combustible metals are used or stored, as improper extinguishing methods could lead to escalated fires and increased risk of harm.
