Which class of fire includes flammable and combustible liquids?

The class of fire that includes flammable and combustible liquids is class B. This classification refers specifically to fires that involve liquids such as gasoline, oil, paints, and other solvents that can ignite and burn. Class B fires require special extinguishing agents, typically foam, carbon dioxide, or dry chemical agents, that are effective in smothering the flames or removing the heat to extinguish the fire.

In contrast, class A fires involve ordinary combustible materials like wood, paper, and textiles. Class C fires are related to electrical equipment and include fires where energized electrical equipment is involved. Class D fires are related to combustible metals, such as magnesium, titanium, and sodium, which require specific firefighting techniques and agents due to their unique burning characteristics. Understanding these classifications is essential for effectively responding to different types of fires and ensuring firefighter safety.
