What class of fire involves oil and grease?

The class of fire that involves oil and grease is classified as Class B. This classification specifically pertains to fires that occur due to flammable liquids, which include oils, greases, paints, and other solvents. These types of fires are fueled by substances that can ignite and burn rapidly, making them particularly hazardous in settings like kitchens or industrial environments where oils are commonly used.

Class A fires, on the other hand, involve ordinary combustibles such as wood, paper, and fabrics, while Class C fires pertain to electrical equipment. Class D fires are associated with combustible metals, which present a different set of challenges in terms of extinguishing methods. Understanding these distinctions is crucial for selecting the appropriate type of fire extinguisher and implementing effective fire prevention strategies in environments where these materials are present.
