1. A method for determining the safety of persons with respect to at least one hazardous gas, toxic gas, combustible gas, oxygen deficiency, and oxygen excess, said method comprising the steps of:
inputting the concentration of each gas determined, as measured concentration values for the concentration, by a plurality of gas-measuring devices into a memory and analysis device; determining a measured value rating number, for a preset period of us, of each of the gas-measuring devices in the memory and analysis device from the measured concentration values for the concentration of each gas; inputting a number of instances, of the measured concentration values exceeding a preset gas concentration limit value for each of the gas-measuring devices, into a memory; and determining a safety code, for rating the safety situation/safety of persons for a plurality of measurement sites as a whole, at which the measurements performed by the gas-measuring devices were carried out, from at least one of: the measured concentration values, of the plurality of gas-measuring devices; and the measured value rating numbers determined from the measured concentration values, of the plurality of gas-measuring devices; and a total number of instances in which a gas concentration limit value was exceeded, which is determined from the measured concentration values, of the plurality of gas-measuring devices. |
