The primary aim of the nationwide warning day is to familiarize citizens and the media with the topic of warnings and to convey the necessary knowledge about warning channels and warning procedures.
The Federal Office of Civil Protection and Disaster Assistance will trigger all available warning devices (e.g. warning apps and warning messages via radio) nationwide at 11:00 a.m. on this day. As a result, around 90 sirens will also be switched on in the Ludwigsburg district at 11:00 am: The signal "One minute wail" means in an emergency: "There is an immediate danger in the area or this is to be expected shortly. Use all possible information media for further instructions, these are broadcast by all local and regional radio stations. Follow the official instructions." At 11:45 a.m. (note the change in time), the sirens are switched on again with the signal "One minute continuous tone", which means: "There is no longer any acute danger. Use all possible information media to obtain further information."
However, some towns and municipalities in the district no longer have sirens: Ludwigsburg, Kornwestheim, Korntal-Münchingen, Marbach, Vaihingen, Ditzingen and Freiberg. Eberdingen is not connected to the general disaster alarm network with its sirens, but can only use them for local fire department alerts.
In towns and municipalities that no longer have sirens or are not connected to the general disaster alert network, the population is warned in an emergency by loudspeaker vans and also via the federal government's NINA (Emergency Information and News App) warning app.
On this nationwide warning day, a test warning message will be sent out for the first time at the highest warning level of the "Cell Broadcast" service. "Cell Broadcast" can be used to send warning messages to all mobile devices - smartphones and conventional cell phones - located in a specific section of the mobile network, a so-called radio cell.
