3% F-500 Encapsulator Agent is used with salt water to fight this oil well fire demonstration in United Arab Emirates, which was successful in less than a minute. This is a three-dimensional, flowing liquid fuel fire. NFPA 11 Annex A.1.1 states, “Foam is not suitable for three-dimensional flowing fuel fires or for gas fires.” It is difficult for foam to extinguish three-dimensional fires because it can’t form a blanket, but F-500 EA can, as it cools and encapsulates the fuel.
