What type of fire is caused by flammable liquids, like grease or oil?

The type of fire caused by flammable liquids, such as grease or oil, is classified as Class B. Class B fires involve combustible liquids and gases, which include substances like gasoline, oils, and solvents that can ignite and produce flames. These fires require specific extinguishing agents that can effectively smother the flames and prevent re-ignition, usually found in fire extinguishers labeled for Class B use.

Understanding the classification of fires is essential for effective fire safety and response. For example, Class A fires involve ordinary combustibles such as wood, paper, and cloth, while Class C fires involve energized electrical equipment, and Class K fires pertain specifically to cooking oils and fats often encountered in kitchens. This classification helps in employing the appropriate firefighting methods and equipment tailored to each fire's characteristics.
