What is one common cause of Class B fires?

Class B fires are primarily fueled by flammable liquids, gases, and oils, which makes this choice the most accurate. These types of fires can involve substances such as gasoline, oil, paint thinners, and solvents, which are all categorized under Class B materials. The nature of flammable liquids allows them to produce vapors that can ignite, leading to rapid fire spread, which is characteristic of Class B.

Understanding the classifications of fire is crucial for effective firefighting and safety protocols, as it helps responders quickly identify the most effective extinguishing agents and techniques to use in a fire scenario. Here, the identification of flammable liquids as a common cause is essential for establishing proper safety measures and fire prevention practices in environments where these materials are present.
