The substance is exceeded a critical concentration of F-500-molecules in the water, due to their amphiphatischen structure as an emulsifier, which is able to convert each other immiscible liquids in an emulsion. In firefighting, a variety of substances, can be hermetically closed water such as gasoline or smoke particles, F-500 issue and removed the firing process due to this property. Also reduces the addition of F-500 the surface tension and the boiling point of water, which it emits a temperature of approx. 70 C water vapour. The forces of the fire fighters used by the relatively cool water vapor in a lower risk of scalding and can run much faster work, for which a touch of fire materials is necessary. Ever after Different ratios of F-500 and water are fire class to use.

In fighting fires of the class A is a up to 1% concentration of the extinguishing medium supplement, in all other classes of reaction to fire a 3% owned. The water mixed with F-500 penetrates quickly into burning substances and cavities. The quick and cool water vapor development brings burning materials below their ignition temperature and the fire goes out. It mixes the extinguishing liquid (97% water + 3% F-500) at least in the ratio of 4:1 under high pressure (> 5 bar) on the nozzle with liquid hydrocarbons in fire (E.g. fuel), is thus able to remove the flammable liquid in the long term and to make brandtechnisch inactive. The resulting emulsion avoiding more flammable vapors, which increases the security of the troops. The use of the extinguishing medium supplement and the mixture requires no special equipment by the fire brigades. It is either made with an existing device or as a Ready mix in fire extinguishing tanker transports.

In use it is not emitted over foam tubes, but usual nozzles, monitors and fire lances. The use of F-500 extinguishing medium mixture for fires of class A are generally like the delete use of additive-free water. The more aggressive the fire fighting attack, the faster the extinguishing success arises. Initially, a straight spray is set directly on the fire, the smoke down and improves the view. After a first extinguishing success has set the deletion forces should closer to the fire with a broader fight against of the fire area. Extends the fire on compact solids like paper or straw bale, whose surface using a spray jet is deleted first. Deviations from the recent deletion tactics to cover burning liquids with extinguishing arise for the fighting class B fires. The chemical properties of F-500 create an extinguishing success converge fast deprivation of heat and air-tight confinement of flammable vapours or free radicals. The most effective fire fighting tactics in this case consists of an aggressive, circling spray of the fire with the fire extinguishing medium mixture. The strength and speed of mixing F-500-carbonated water mixture and burning liquid determines how quickly and effectively the extinguishing success is achieved. Further questions about F-500 and effective fire protection, which are inherently unnecessary use of fire can be at any time are happy to answer fire protection experts of the Essen fire service EBS.
