Class B fires are caused by which of the following?

Class B fires are specifically classified as fires that involve flammable or combustible liquids and gases. This includes materials such as gasoline, oil, paint, and solvents, which can ignite and spread flames quickly. Firefighting techniques used for Class B fires often involve smothering the flames with foam or using dry chemical extinguishers that are designed to interrupt the combustion process of such liquids.

Understanding the nature of Class B fires is crucial for effective fire prevention and firefighting strategies, as these types of fires require different approaches and extinguishing agents compared to fires caused by ordinary combustibles, electrical equipment, or ignitable metals. Each of these categories has its own distinct characteristics and required handling procedures, emphasizing the importance of proper training and knowledge in safely managing fire hazards.
