Which type of extinguisher is specifically designed for flammable metals?

1. Class A

2. Class B

3. Class C

4. Class D

The correct answer is: Class D

The type of extinguisher specifically designed for flammable metals is Class D. Class D fire extinguishers are formulated to combat fires caused by combustible metals such as magnesium, titanium, and sodium. These metals can ignite and burn at very high temperatures, and they react with water, making standard extinguishing methods ineffective and potentially dangerous. Class D extinguishing agents vary but often contain dry powder compounds that smother the flames or create a barrier between the fuel and the oxygen, effectively controlling and extinguishing the fire. Understanding the appropriate extinguishing method is crucial for safety and effectiveness in emergency situations involving flammable metals.
