Which type of fire involves flammable liquids like oil?

The correct choice refers to fires that involve flammable liquids such as oil, gasoline, and other combustible liquids. These types of fires are categorized as Type B fires. This classification is crucial because the approach to extinguishing these fires differs from that of other types.

Type A fires involve ordinary combustibles such as wood, paper, and cloth. They are handled differently due to the solid nature of the materials burning. Type C fires pertain to energized electrical equipment, which necessitates caution to avoid electrocution or further complications. Type D fires involve combustible metals, which require specialized extinguishing agents due to the unique behaviors of these metals when they burn.

Understanding the characteristics of Type B fires is essential for proper fire safety and response, as using the wrong type of extinguishing agent on flammable liquids can lead to more dangerous situations, such as spreading the fire or causing explosions. Recognizing these distinctions helps ensure a safer environment when dealing with various fire hazards.
