Which type of fire is primarily caused by flammable liquids?

The classification of fires is essential for understanding how to effectively combat them. Fires that are primarily fueled by flammable liquids, such as gasoline, oil, or solvents, fall into the category known as Class B fires. These types of fires are distinguished by the fact that they involve combustible liquids or gases, which ignite and can spread rapidly.

Class B fires require specific extinguishing methods because using water may exacerbate the fire. Instead, these fires are typically fought with foam, dry chemical, or carbon dioxide extinguishers, which can effectively smother the fire or interrupt the chemical reaction that fuels it.

In contrast, other fire classes involve different materials. Class A fires pertain to ordinary combustibles such as wood, paper, and cloth; Class C fires are associated with electrical equipment; and Class D fires involve combustible metals. Understanding these distinctions is crucial for effective fire response and prevention strategies.
