What is the primary component of a Class B fire?

Class B fires are primarily fueled by flammable liquids, such as gasoline, oil, grease, and solvents. These substances are characterized by their ability to ignite and sustain burning, which poses unique hazards compared to fires involving other materials. The method for extinguishing Class B fires typically involves smothering the flames or using agents that can cool the burning liquid or interrupt the combustion process.

Understanding the nature of Class B fires is crucial for effective fire prevention and response strategies, as they require specific types of fire extinguishing agents like foam, dry chemical, or carbon dioxide to effectively suppress the flames. Knowing this helps ensure safety protocols are correctly followed in environments where flammable liquids are present, thereby minimizing risk and potential damage.
