In the context of fire classes, what does Class Bravo fire refer to?

Class Bravo fires specifically refer to those involving flammable or combustible liquids and gases. This category encompasses a wide range of substances, including gasoline, diesel fuel, oil, solvents, and various gases like propane. The significance of identifying Class Bravo fires lies in understanding the appropriate methods for extinguishing them; due to the nature of these materials, water is generally not effective and can even exacerbate the situation. Instead, fire suppression agents such as foam, dry chemical agents, or CO2 are often employed to smother the flames by depriving them of oxygen or creating a barrier.

In contrast, the other classifications pertain to different types of fires. For example, combustible metals represent a distinct category; fires fueled by these materials often require specialized extinguishing agents due to their unique combustion properties. Energized electrical equipment also falls into its own classification, as it may pose additional hazards (such as electrical shock) if water or inappropriate extinguishing agents are used. Lastly, wood and paper products are designated as Class Alpha fires, which can effectively be tackled using water, unlike Class Bravo fires. Understanding these classifications is crucial for ensuring safe and effective firefighting strategies.
