Information by radio

ICARO: Instructions at any time by radio

Swiss Radio and Television Corporation (SRG SSR) and numerous private broadcasting services disseminate instructions by radio. With its ICARO (Information Catastrophe Alarm Radio Organisation) emergency regime, the SRG ensures that in all special and exceptional situations, official notifications are broadcast via its first channels immediately and at any time. Running programmes are interrupted in such cases. All operations centres of the cantonal police are connected to the ICARO system.

TOM: federal notifications on natural dangers

Public and private radio and television producers broadcast federal warnings against major and extreme natural dangers. To enable the compilation and transmission of notifications on natural dangers, the National Emergency and Operations Centre (NEOC) runs the TOM (Transmission of Official Messages) application. The agencies for natural dangers -the Federal Office for Meteorology and Climatology (MeteoSchweiz), the Federal Office for the Environment (FOEN), the Swiss Institute for Forest, Snow and Landscape Research (WSL) the Institute for Snow and Avalanche Research (SLF), the Swiss Seismological Service (SED) - thus compile (predefined) notifications and transmit them to the radio and TV companies in the affected area that are obliged to broadcast the information.

IBBK: emergency transmission network for critical situations

It must be possible to provide the public with official information in any situation. For this purpose the normal (radio) infrastructure and processes are basically available . However, it is conceivable that due to a disaster or an emergency ordinary structures function only to a limited degree or not at all. In such a case, the IBBK radio with its wide availability and great broadcasting power can be put into operation. IBBK radio is the abbreviation for ‘Information by radio of the public by the Confederation in an emergency’ and designates Switzerland’s VHF radio broadcasting network. It would also ensure that the public would be able to receive instructions when living in shelters.
