KATRETTER – Everybody can help!

When rescuing people, every minute often counts. In many emergencies or crisis situations, volunteers could help with their specific knowledge and skills. In the city of Berlin alone, there are around 3,600 relevant occasions every year.

The KATRETTER system supports the rescue services to inform the right volunteers within seconds - mobile, legally secure and exact to the place.

You would like to implement KATRETTER in your control centre or use it as an smartphone application? We will be happy to answer your questions:

KATRETTER can be used uniformly by all municipal rescue organisations and control centres throughout Germany and is available free of charge to people who wish to volunteer on site.

Service for Rescue Departments and Coordination Centers

KATRETTER is based on the results of a three-year research project of the German Federal Ministry of Education and Research (BMBF), in which, among others, the fire-brigades of Berlin and Fraunhofer FOKUS have played a significant role. The integration of data protection experts and controllers in accordance with the principle of 'privacy by design' provides a legally secure coordination and performance of alerting and disaster operations. Additionally, the efficient process of registration of volunteers ensures that the administrative expense is kept to a minimum.
