KATRETTER – Everybody can help!

When rescuing people, every minute counts. In many emergencies or crisis situations, volunteers could help with their different knowledge and abilities.

KATRETTER is a system for first aid volunteers: If they are in the vicinity of an emergency location, they are asked for their help directly by the rescue services via the KATRETTER application.

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.

Would you like to implement KATRETTER in your control centre or use it as a smartphone application? We will be happy to answer your questions:

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.
