Which class of fire includes flammable metals like aluminum and sodium?

• A. Class A
• B. Class B
• C. Class C
• D. Class D

Answer: (D)

The class of fire that includes flammable metals such as aluminum and sodium is classified as Class D. Class D fires involve combustible metals that can ignite and burn at high temperatures. These types of materials require special extinguishing agents, as typical methods used for Class A, B, or C fires would not be effective and could actually exacerbate the situation. For example, water is often used for Class A fires, which involve ordinary combustibles like wood or paper, but using water on flammable metals can lead to explosive reactions. Class B fires involve flammable liquids and gases, while Class C fires pertain to electrical fires. However, neither of these classes includes the specific hazards presented by flammable metals, which is why it's critical to recognize and respond appropriately to Class D fires. Understanding this distinction is vital for firefighter safety and effective firefighting strategy.
