Which class of fire involves flammable liquids, gases, and greases?

The classification of fires according to the type of materials that ignite is crucial for effective fire safety management. Fires involving flammable liquids, gases, and greases fall under Class B. This category includes substances such as gasoline, oil, alcohol, solvents, and other materials that can produce flammable vapors.

Using the appropriate extinguishing agents is essential when dealing with Class B fires. For example, foam or dry chemical extinguishers are specifically designed to combat these types of fires by smothering the flames and preventing the release of flammable vapors. This categorization helps ensure that responders use the right methods and equipment to effectively extinguish different types of fires while minimizing risk and maximizing safety.

In contrast, Class A fires involve ordinary combustibles like wood, paper, and cloth; Class C fires pertain to electrical equipment; and Class D fires are related to combustible metals, which highlight the diversity of fire behaviors and requirements for appropriate firefighting techniques. Thus, the correct identification of fire classes is vital for safety and effective response during fire emergencies.
