• A. Type A fire extinguisher
• B. Type B fire extinguisher
• C. Type C fire extinguisher
• D. Type D fire extinguisher

Answer: (D)

Fires are handled by matching the extinguisher to what’s burning. For fires involving metals, you need a extinguisher designed specifically for metal fires. These use a dry powder or special agents that coat and separate the burning metal from oxygen and moisture, cooling it and choking the chemical reaction. Water or standard extinguishers used for wood/paper, flammable liquids, or electrical fires can be unsafe or ineffective on metal fires, and in a chemical laboratory where reactive metals may be present, a metal-fire extinguisher is the appropriate tool. That’s why the extinguisher designed for metal fires is the best choice for chemical labs dealing with such hazards.
