Hallo,
Geschrieben von >Wikipedia EN
In firefighting: Emulsifying agents are effective at extinguishing fires on small thin layer spills of flammable liquids (Class B fires). Such agents encapsulate the fuel in a fuel-water emulsion, thereby trapping the flammable vapors in the water phase. This emulsion is achieved by applying an aqueous surfactant solution to the fuel through a high-pressure nozzle. Emulsifiers are not effective at extinguishing large (i.e., deep) fires involving liquid fuels, because the amount of agent needed for extinguishment is a function of the volume of the fuel, whereas agents such as aqueous film-forming foam (AFFF) need cover only the surface of the fuel to achieve vapor mitigation.
