Die Erfindung richtet sich auf ein Verfahren zur Brandbekämpfung unter Einsatz eines Löschmittelwerfers, insbesondere einer Löschmitteldüse eines Handlöschgerätes, wobei ein Löschmittelstrahl bei Betätigung eines Aktivierungselementes freigesetzt wird, sowie auf eine Vorrichtung insbesondere zur Durchführung des Verfahrens.The invention is directed to a fire fighting method using an extinguishing agent thrower, in particular an extinguishing agent nozzle of a hand-held extinguisher, wherein an extinguishing agent jet when actuating an activation element is released, as well as on a device in particular to carry out the procedure.
Bei der Brandbekämpfung, insbesondere mit Einsatz eines Handlöschgerätes, wird der Brandherd mit Hilfe eines Löschmittels aus einer Düse, die in der Regel einen Löschmittelstrahl erzeugt, bekämpft. Löschpulver auswerfende Düsen sind häufig mit einem sich nach außen erweiternden Trichter ausgerüstet, um eine Pulverwolke zu erzeugen. Wird mit einem Strahl gelöscht, muß die das Handlöschgerät benutzende Person zur Erhöhung der Löschwirkung Schwenkbewegungen ausführen oder auf andere Weise versuchen, den Löschmittelstrahl dann zu zerstäuben, wenn eine breitere Fläche mit Löschmittel überstrichen werden soll.When fighting fires, especially when using a Extinguishing device, the source of the fire is extinguished with the help of an extinguishing agent from a nozzle, which is usually a jet of extinguishing agent generated, fought. Extinguishing powder ejecting nozzles are often with a funnel widening outwards equipped to generate a powder cloud. Will with a Beam extinguished, the one using the hand-held extinguisher Carry out swiveling movements to increase the extinguishing effect or otherwise try the jet of extinguishing agent then atomize when using a wider area Extinguishing media should be painted over.
Die Regel ist darüber hinaus, daß Handlöschgeräte nur mit einer Art von Löschmittel gefüllt sind. Bei Großlöschanlagen ist es bekannt, aus unterschiedlichen Löschmittelwerfern ggf. auch unterschiedliche Qualitäten von Löschmitteln in den Brandherd einzuschießen, wie dies in der US-A-3 448 809 beschrieben ist.The rule is also that hand-held extinguishers only with some kind of extinguishing agent. For large extinguishing systems it is known from different extinguishing media throwers possibly different qualities of extinguishing agents to shoot into the source of the fire, as in US-A-3 448 809.
Beispielsweise aus dem DE-U-1 782 540, der DE-A-1 948 510 oder der US-5 344 080 sind Düsen bekannt, mit denen unterschiedliche Strahlausbildungen möglich gemacht werden, insbesondere hinsichtlich des Personenschutzes, etwa in Art einer "Personenschutzbrause". Eine Optimierung des Löschvorganges selber, d.h. des Löschverfahrens, ist mit den bekannten Lösungen nicht möglich.For example from DE-U-1 782 540, DE-A-1 948 510 or US-5 344 080 nozzles are known with which different Beam training can be made possible, in particular with regard to personal protection, e.g. in Art a "personal protection shower". An optimization of the deletion process itself, i.e. the extinguishing process, is familiar with the Solutions are not possible.
