Class B fires are classified based on what type of material?

Class B fires are defined by the materials that fuel them, specifically flammable liquids and gases. This classification is critical in firefighting and safety protocols, as it indicates the types of substances involved in the fire, which require specific extinguishing methods and agents.

Flammable liquids and gases can include materials such as gasoline, oil, paint, solvents, and propane. Understanding that Class B fires arise from these substances informs responders to use appropriate fire extinguishing agents, such as foam, dry chemical, or carbon dioxide, which are effective against these types of fuels.

In contrast, electrical equipment fires relate to Class C fires, while cooking oils and food are categorized as Class K fires. Solid combustible materials, on the other hand, correspond to Class A fires. Each classification's unique characteristics guide safe and effective firefighting strategies. Thus, the categorization of Class B fires emphasizes the hazardous nature of flammable liquids and gases, which is essential for effective emergency response training and practices.
