F-500 EA is an Encapsulator Agent. Since it extinguishes fires by encapsulating fuels and vapors, cooling the fuel and surrounding surfaces and by interrupting the free radical chain reaction, F-500 EA is well suited for three-dimensional Class B fires. Unlike foam, F-500 EA does not need to form a blanket to smother a fire. In fact, NFPA 11 Annex A.1.1. states, "Foam is not suitable for three-dimensional flowing liquid fuel fires or for gas fires."
These videos show F-500 EA's exceptional ability to extinguish fires where foam would not be able to form a blanket.
