Which of the following is typically used to extinguish Bravo fires?

Bravo fires involve flammable liquids such as petroleum products, oils, and solvents, which require specific suppression agents to be effectively extinguished. AFFF, or Aqueous Film-Forming Foam, is particularly suitable for this type of fire because it creates a film on the surface of the burning liquid, effectively sealing off the fuel from the oxygen in the air, thus stopping the combustion process. This foam not only cools the flames but also suppresses the release of flammable vapors from the liquid, making it a highly effective and efficient option for extinguishing Bravo fires.

In contrast, using water on a Bravo fire can be dangerous as it may cause the flammable liquid to spread or even create steam explosions. Other options like sand can provide some suppression by smothering the fire but are less effective in terms of cooling and do not address the vapors. CO2 can be used on some flammable liquid fires but is generally more effective on smaller, contained fires rather than larger Bravo fires that AFFF is designed to manage effectively.
