Method for operating an evacuation system for supporting an evacuation event, in particular an evacuation of a building, comprising the following steps of: a. providing a Bluetooth-based recognition system comprising at least one registration unit (3 or 3'), which is positioned at the workplace, and at least one Bluetooth tag, which is carried by the person (2, 6, 8) to be recognized, wherein the Bluetooth tag has a data set with an individual identifier for identifying the person; b. initiating an alarm due to an evacuation event within a danger zone; c. providing one or the registration unit (3', 3) at a location outside the danger zone; d. scanning the registration unit (3', 3) for at least one Bluetooth tag, in particular a plurality thereof, which is matched to the registration unit (3', 3); e. transmitting a signal, in particular comprising the data set, by the respective Bluetooth tag; f. receiving the signal by the registration unit (3', 3) with simultaneous determination of the time of reception by a time recording of the registration unit (3', 3) and/or the position of the person (2, 8) with the inclusion of geographical data with regard to the location of the registration unit (3', 3), and g. comparing the data determined in step d) with a data log comprising a data set created prior to the evacuation event comprising a last detected time and a last detected location of the person in the danger zone prior to the initiation of the evacuation event according to step b; and h. updating the data log, wherein the evacuation system comprises a plurality of registration units, wherein further registration units remain in the danger zone in addition to the registration unit provided in step c, wherein these registration units carry out steps d-f in the danger zone by creating a data record and transmitting this to the network or to a higher-level IT infrastructure for determining the position of the person in the danger zone, characterized in that the registration unit at the location outside the danger zone is designed as a mobile terminal and in that the registration units in the danger zone have a quick dial field for connection to the registration unit at the location outside the danger zone. a. providing a Bluetooth-based recognition system comprising at least one registration unit (3 or 3'), which is positioned at the workplace, and at least one Bluetooth tag, which is carried by the person (2, 6, 8) to be recognized, wherein the Bluetooth tag has a data set with an individual identifier for identifying the person; b. initiating an alarm due to an evacuation event within a danger zone; c. providing one or the registration unit (3', 3) at a location outside the danger zone; d. scanning the registration unit (3', 3) for at least one Bluetooth tag, in particular a plurality thereof, which is matched to the registration unit (3', 3); e. transmitting a signal, in particular comprising the data set, by the respective Bluetooth tag; f. receiving the signal by the registration unit (3', 3) with simultaneous determination of the time of reception by a time recording of the registration unit (3', 3) and/or the position of the person (2, 8) with the inclusion of geographical data with regard to the location of the registration unit (3', 3), and g. comparing the data determined in step d) with a data log comprising a data set created prior to the evacuation event comprising a last detected time and a last detected location of the person in the danger zone prior to the initiation of the evacuation event according to step b; and h. updating the data log, wherein the evacuation system comprises a plurality of registration units, wherein further registration units remain in the danger zone in addition to the registration unit provided in step c, wherein these registration units carry out steps d-f in the danger zone by creating a data record and transmitting this to the network or to a higher-level IT infrastructure for determining the position of the person in the danger zone, characterized in that the registration unit at the location outside the danger zone is designed as a mobile terminal and in that the registration units in the danger zone have a quick dial field for connection to the registration unit at the location outside the danger zone.
