Across the world, the structure of THW is unique: As a Federal agency, THW belongs to the department of the Federal Ministry of the Interior, Building and Community. However, only one percent of the staff works full-time for the authority. 99 percent of the THW-members work on a voluntary basis for THW. Nationwide more than 80,000 volunteers commit themselves during their leisure time in 668 local sections in order to provide professional help to people in distress. THW flexibly adapts its structures to changing threat situations. Modern equipment and well-trained specialists are the basis of its high efficiency. THW participates in the worldwide intermeshing of all relief organisations as an internationally active operational organisation.As a competent partner, the Technische Hilfswerk is assigned a sustaining role by the United Nations as well as in the European Union.
