Definitions

  • the present invention relates to a method for combating a fire event.
  • the invention further relates to a system for executing this method and a control unit for combating a fire event.
  • the amount of extinguishing agent is calculated and provided, and the selection and arrangement of the nozzles is selected so that it is highly likely that the fire will be contained or prevented from spreading until the fire department arrives, or even extinguished.
  • a disadvantage of the known methods is, among other things, high water consumption. Large quantities of extinguishing agent must also be kept in stock, since the entire amount of extinguishing agent is usually applied after the extinguishing system has been triggered or after it has been extinguished. This results in systems with high costs in terms of construction and maintenance. So there is a big one Space required for the extinguishing agent storage containers.
  • an extinguishing agent having a first extinguishing effect being applied by means of at least one dispensing device in the first extinguishing phase
  • an extinguishing agent with a second extinguishing effect is applied to the location PL and / or its surroundings in a demand-controlled manner, the second extinguishing characteristic being different from the first extinguishing effect.
  • a fire event is understood to mean that a fire breaks out and exhibits special fire behavior.
  • the fire usually arises from a singular event and can remain localized. However, if there is a spatial spread, the fire will go beyond the original place of origin. Often the fire at the original place of origin can be minimized or even extinguished by successfully fighting the fire or using the used fuel. However, it can happen that one or more residual sources of fire remain or develop there.
  • a residual fire may exist or develop at the point of origin and / or at another location. Accordingly, the location of the residual fire may no longer correspond to the location where the fire started.
  • a fire that has been fought and that continues to exist as a result of the spread of the fire is also referred to below as a residual fire.
  • a residual fire can also have the size and location of the fire before the first extinguishing phase of the fire-fighting if the means of fighting the fire were not successful in the first extinguishing phase, so that the second phase is necessary.
  • the location of a residual fire is referred to as the location PL.
  • the location of a residual fire can thus be very limited locally or encompass a larger area.

  • fire parameters include electromagnetic radiation, in particular in the UV and / or IR wavelength range, heat radiation, aerosols (in particular smoke aerosols), temperatures, gas concentrations, gas compositions and / or changes in the concentration of certain gaseous components of combustion gases, thermal decomposition products, toxic or combustible gases or others that characterize a fire, understood.
  • the one or more sensor devices are preferably arranged in one or more housings.
  • the one or more sensor devices are arranged in fire detectors, such as flame detectors, heat detectors, smoke detectors, gas detectors, multisensor detectors or cameras.
  • the detection unit is preferably set up to record the fire event, monitor the fire event, record the fire event parameters and preferably also the location PL of the Rest exposed to fire. Detection of the location PL is preferably understood to mean the determination of the position and the area AR of the residual fire source.
  • the surface can be a horizontal, vertical and / or generally angularly arranged surface in space.
  • the three-dimensional extent of the residual fire source is preferably detected or determined as the location PL. This is advantageous, for example, for water mist extinguishing systems or water mist extinguishing devices, since here the spatial extent of the extinguishing agent must also be taken into account when it is applied to the object to be protected.
  • a first extinguishing phase is started in a next method step.
  • the extinguishing agent of the first extinguishing phase has a first extinguishing effect.
  • the extinguishing agent and the extinguishing effect are preferably selected according to the fire scenario to be expected and the potentially flammable substance.
