The MIL-PRF-32725 document titled "Fire Extinguishing Agent, Fluorine-Free Foam (F3) Liquid Concentrate, for Land-Based, Fresh Water Applications" governs the use of fluorine-free foam (F3) liquid concentrate fire extinguishing agents. These agents are specifically designed for use on class B hydrocarbon liquid fuel fires in land-based applications. The document is approved for use by all Departments and Agencies of the Department of Defense. The F3 agents are not intended for use on polar solvents or for U.S. Navy shipboard use. The concentrates are to be diluted with fresh water at the time of use to form a foam solution. The document also covers additional requirements for mis-proportioned foam solutions.
