What type of materials are involved in a Class B fire?

Class B fires are specifically related to flammable liquids and gases. This class includes materials such as gasoline, oil, alcohol, and various solvents which can ignite easily and burn rapidly, posing significant hazards due to their volatile nature. Understanding the characteristics of Class B materials is crucial for effective firefighting strategies, as they require different extinguishing agents compared to other classes of fires. For example, water is ineffective and can even exacerbate Class B fires, whereas foam, dry chemical, or carbon dioxide extinguishers are appropriate for suppressing these flames. Recognizing these types of fires is essential for both firefighting personnel and safety awareness in environments where flammable liquids are present.
