Definitions

  • the present invention relates to the use of a solution which can not only be used to extinguish fires or fires, but also for, in particular, short-term and / or temporary flame-proofing of a wide variety of materials, such as wood, textiles or porous plastic objects , is suitable.
  • inorganic salts such as, for example, alkali or alkaline earth metal salts of carbonic acid, phosphoric acid, boric acid and the like
  • Relatively concentrated solutions are used, whereby the dissolved salts support the extinguishing effect of the water on the fires in so far as either inert gases are released during the heating process, which does not release the fire-maintaining gases (such as C0 2 in the case of carbonates) or the salts during heating melt and in turn cover the burning materials with a melt that prevents oxygen access.
  • the pure extinguishing effect of the water is significantly supported.
  • the present invention has set itself the goal of finding a solution for extinguishing fire which does not have the above-mentioned disadvantage and which, moreover, is also already prophylactic, due to this fact. H. for short-term or temporary flame retarding of materials.
  • the present invention thus relates to the use of, in addition to optionally alkali metal hydrogen carbonate and / or optionally volatile or gaseous blowing agent, exclusively alkali metal citrate in a concentration of 10% by weight up to the saturation concentration having an aqueous solution for extinguishing fire and at the same time flaming the surroundings of the source of the fire .
  • the solution used according to the invention is not only suitable for fire fighting, but also for preventive fire protection on the one hand, the environment of a fire by fire-retardant impregnation and, on the other hand, of objects which are to be temporarily protected from possible fires.
  • the fire protective applied solution after it has served its purpose, can be removed from the object in question easily and without leaving any damage or discoloration of the object.
  • the solution used according to the invention is also suitable for use in automatic fire extinguishers in which, as in the case of a sprinkler system, for example, extinguishing liquid is sprayed automatically when smoke or when a certain temperature increase occurs.
  • extinguishing liquid is sprayed automatically when smoke or when a certain temperature increase occurs.
  • the essential effect of the solution used according to the invention is that it can be easily removed again after it has served its purpose, without requiring a substantial amount of work and, above all, without affecting the objects from which it is to be removed. any permanent damage occurs.
  • the solution used according to the invention is particularly suitable for the flame-resistant impregnation of objects which in turn are only used for a short time;
  • Spraying with the solution used according to the invention is easy to carry out since it is completely harmless to health and certainly prevents the formation of a dreaded Christmas tree fire, even if the tree itself has already dried out to a large extent and is therefore inherently flammable.
  • the pressure required to spray the solution can be built up by the constituents themselves in the closed vessel.
  • the substances specified should not be used for fire fighting per se, but only for binding the released gases, which means that these substances are added to the extinguishing liquid in a relatively small proportion. It is expressly stated that the substances are preferably used in a proportion of 1%.
  • the proposal according to the invention is based on using the alkali metal citrate, possibly in a mixture with the bicarbonate, as such for fighting fires, the salts being provided in substantially larger proportions in the extinguishing water.
  • a cup with a diameter of 30 cm and a height of approx. 2 cm was filled with oil, set on fire and then extinguished when sprayed for the first time.
  • the pressure of the liquid sprayed on the oil blows the fire aside.
  • the subsequent fire protection agent then closes the surface of the oil with this agent; this will extinguish the fire.
  • a white film is formed on the oil surface, which comes from the fire protection agent.
  • the solution used according to the invention was inflated onto the oil by a small atomizer.
