What class of fire is associated with oil or grease?

The correct answer relates to the classification of fires based on the type of material that fuels them. Fires involving oil or grease are categorized as Class B fires. These types of fires typically involve flammable liquids, such as oils, solvents, gasoline, and other petroleum products.

Class B fires require specific extinguishing methods, often using foam, CO2, or dry chemical agents, to deprive the fire of oxygen or interrupt the chemical reaction. Understanding this classification is essential for effective fire safety and response in environments where these materials are present, such as kitchens or industrial settings.

In contrast, Class A fires involve ordinary combustibles like wood and paper, Class C fires are fueled by electrical equipment, and Class D fires involve combustible metals. Each class has distinct methods of extinguishment that are tailored to the characteristics of the burning material. Recognizing the different classes of fire helps ensure appropriate firefighting techniques are applied to prevent injury and further property damage.
