What fire-fighting agent is recommended for all composite fire conditions?

Aqueous film forming foam (AFFF) is recommended for all composite fire conditions because it is highly effective against various classes of fires, including those involving flammable liquids, solids, and gases. AFFF works by creating a film that not only cools the fire but also seals the surface of the burning material, helping to prevent re-ignition. This dual action allows for a more comprehensive approach to fire suppression, especially in scenarios where different types of materials may be burning together, which is typical in composite fire conditions.

Moreover, AFFF is designed to be versatile and can be used in a wide range of firefighting situations, making it an essential tool for firefighters who need to address complex fire dynamics involving multiple combustible materials. Its ability to adhere to surfaces and suppress vapor emissions further enhances its effectiveness, ensuring a safer environment for both responders and potential victims.
