What type of fire involves materials like gasoline or diesel fuel?

The type of fire that involves materials like gasoline or diesel fuel is classified as a Class B fire. These types of fires are fueled by flammable liquids, gases, or greases, making them distinct from other classes of fires. Class B fires typically include materials such as oil, gasoline, propane, and other hydrocarbons.

When it comes to extinguishing Class B fires, specific types of extinguishing agents are used, such as foam, dry chemical agents, or carbon dioxide, as water is not effective and can actually spread the flammable liquid. Understanding the classification of fires is crucial for firefighters, as it determines the appropriate firefighting tactics and equipment to use, ensuring both safety and effectiveness in addressing the fire.
