What class of fire involves combustible metals such as magnesium and sodium?

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

Answer: (D)

The correct classification of fire involving combustible metals, such as magnesium and sodium, corresponds to Class D fires. Class D fires are characterized by the combustion of flammable metals, which require special extinguishing methods and agents that are specifically designed to handle such materials. These metals can burn at extremely high temperatures and often react violently with water and other common extinguishing agents, making it crucial to use the right type of fire suppressant. Class A fires involve ordinary combustibles like wood, paper, and cloth, while Class B fires pertain to flammable liquids and gases such as gasoline and oil. Class C fires involve energized electrical equipment. Each of these classes has distinct properties and recommended suppression techniques, but when it comes to combustible metals, Class D is specifically designed to address their unique hazards and behaviors during combustion.
