What type of fire is associated with flammable liquids and gases?

The classification of fires is based on the materials that are burning, and Class B fires specifically involve flammable liquids and gases. This includes substances like gasoline, oil, alcohol, and other similar materials that can ignite and produce a significant amount of heat and flames.

Class B fires are characterized by their ability to spread quickly and pose severe risks, as flammable liquids can create large, volatile fireballs and can easily ignite other combustible materials. To extinguish Class B fires, special methods and extinguishing agents, such as foam or dry chemical extinguishers, are used. These agents work by smothering the fire, removing heat or interrupting the combustion process, making it essential for firefighters to understand the specific tactics needed to effectively manage such situations.

In contrast, other classes of fires involve different materials: Class A fires involve ordinary combustibles like wood or paper, Class C fires pertain to electrical equipment, and Class D fires are associated with combustible metals. Each class requires a tailored approach to extinguishment, reinforcing the importance of recognizing what type of fire is being dealt with.
