What type of fires does Class B refer to?

Class B fires specifically refer to fires that involve flammable liquids and gases. This category encompasses a wide range of substances, including gasoline, oil, grease, solvents, and paint thinners, which can ignite and produce fast-moving flames. Understanding Class B fires is crucial for fire guards and safety personnel, as these types of fires require specific extinguishing agents, such as foam, dry chemical, or carbon dioxide, rather than water, which can spread the fire.

In the context of fire safety, it's essential to recognize the nature of the material burning because each class of fire presents unique risks and requires different firefighting strategies. Flammable liquids can not only burn but can also produce vapors that ignite easily, making them particularly dangerous in commercial and industrial settings.

Identifying fires correctly ensures an effective response, which is vital for maintaining safety and preventing extensive damage. Thus, when faced with a fire situation involving flammable liquids, proper recognition of it as a Class B fire is foundational for implementing the appropriate fire control measures.
