Project description

On September 10, 2020, the first nationwide warning day took place in Germany. At 11 a.m., sirens and other warning systems were to be triggered throughout Germany and a warning was to be transmitted on radio, television and via apps.

The aims of the warning day were, on the one hand, to check the technical processes and also the warning devices themselves for their function and possible weaknesses on the basis of a test warning. On the other hand, the people in Germany were to be informed about the warning of the population and thus sensitized.

On the day of the warning, technical problems meant that the test warning was only sent out after a delay. In addition, no siren signals could be heard in many places, as the siren network in Germany does not cover the whole country. This led to numerous responses from the population. For Warning Day 2022, the BBK is now preparing a way to systematically process and evaluate corresponding feedback.

The KFN will take over this evaluation and design a questionnaire that will serve as a feedback channel for the population. With the help of this short questionnaire, the impressions of the population on Warning Day 2022 are to be processed. Among other things, it is to be worked out which persons were informed in which way about the warning message on the nationwide warning day and what the subjective feeling of safety of the respondents looks like.
