This can be done through various channels, e.g.
- Radio and TV
- Website of the National Crisis Center or the municipality
- Social media (e.g. @CrisiscenterBE)
- Police patrol cars driving through the streets.
The best way to prepare yourself is to be well informed about what to do in case of an alarm, know what channels are available and subscribe to them.
