1. A process for an analysis of data provided by a mobile gas measuring device, the process comprising the steps of:
generating measured data, by the mobile gas measuring device, based on at least one measurement of a gas concentration in a monitored area;
transmitting the measured data to an additional mobile gas measuring device or to a central data processing unit or to an additional mobile gas measuring device and to a central data processing unit;
comparing the measured data with a limit value stored in any of the mobile gas measuring device, the additional gas measuring device and the central data processing unit to determine if there is a limit value violation comprising an inadmissible overshooting or undershooting of the limit value;
generating an alarm control signal, suitable for taking an action, by any of the mobile gas measuring device, the additional gas measuring device and the central data processing unit, for the limit value violation;
determining a hazard potential in any of the mobile gas measuring device, the additional gas measuring device and the central data processing unit in case of a determined limit value violation, taking into consideration weighted influencing variables;
assigning the hazard potential determined to the limit value violation;
upon a first limit value violation and at least one second limit value violation being determined during a common time period or during overlapping time periods, comparing hazard potentials of the first limit value violation and of the at second limit value violation to one another to determine a prioritization of limit value violations based on comparing hazard potentials,
wherein the generation of the alarm control signals for the first limit value violation and for the at least one second limit value violation is carried out based on the determined prioritization of limit value violations.
