Which class of fire is NOT associated with flammable metals?

Class C fires are defined as those involving flammable gases, rather than flammable metals, which is why this classification is the one not associated with flammable metals. Flammable metals, such as magnesium, titanium, and sodium, are categorized under Class D fires. This class requires special extinguishing agents that can deal safely and effectively with such materials.

In contrast, Class A fires involve ordinary combustibles like wood and paper, while Class B fires pertain to flammable liquids and gases. Therefore, Class C's focus on electrical equipment and energizing a fire due to gas interactions distinctly separates it from the Class D fires that involve metals. Understanding these classifications is crucial for implementing effective fire safety measures tailored to the specific materials involved.
