What is the appropriate fire extinguishing agent for Bravo fires?

For Bravo fires, which involve flammable liquids such as gasoline, oil, and other hydrocarbons, the most effective extinguishing agent is Aqueous Film-Forming Foam (AFFF). AFFF is specifically designed to tackle flammable liquids by forming a film over the surface of the burning liquid. This film not only helps suppress the flame but also prevents the release of flammable vapors, effectively smothering the fire.

Using water on Bravo fires can be dangerous because water can spread the flammable liquid, potentially causing the fire to spread further. Similarly, CO2 is often more suitable for Class B fires involving flammable gases or electrical equipment rather than liquids, as it does not provide the necessary cooling effect on the liquid fuels. While sand can be used in certain scenarios to smother flames, it is not as effective or commonly recommended as AFFF, which is purpose-engineered for such fires. Therefore, AFFF emerges as the most appropriate and effective agent for extinguishing Bravo fires.
