Which category includes flammable liquids?

Flammable liquids are categorized as Class B materials in fire safety classifications. This classification specifically encompasses substances that can ignite and combust at relatively low temperatures, typically below 140°F (60°C). Examples of flammable liquids include gasoline, alcohol, and various solvents used in industrial and household applications.

Class B fires involve the combustion of these liquids, and they typically require special methods for suppression, such as foam, carbon dioxide, or dry chemical extinguishers designed for flammable liquids. Understanding this classification is crucial for fire investigators and first responders, as it guides them in determining appropriate firefighting strategies and safety measures when encountering these hazardous substances.

In contrast, the other classifications serve different types of materials and fires. Class A is for ordinary combustibles like wood and paper, Class C is for electrical fires, and Class D pertains to combustible metals, which do not fit the description of flammable liquids. Class K is specifically for cooking oils and fats. Thus, it is essential to recognize Class B as the correct classification for flammable liquids.
