An accident must be considered as a multi causal choice phenomenon. An inventory of the situation as regards the unsafety in the different systems of dwelling, occupation and transport covers not only data which show the sincerely of the situation but also the questions : What is being done; What can be done and How can it be organised. A plea is given for a change in thinking. The different theories of thinking which find general favour today, and which arise disturbances in communication by their difference in source and which through these are in the way for an efficient solution of the problem of unsafety are discussed.Strategies for the control of unsafety can be divided into five phases with different priorities, which are outlined. The organisation and decision process for the control of the unsafety in the above mentioned systems are discussed.
