Abstract
Most of troubles/accidents that recently occur are caused by inappropriate human behaviors. To suppress troubles/accidents due to these inappropriate behaviors, preventive activity is essential. Although several models of preventive activity have already been proposed, current status and issues of preventive activity in typical fields have not sufficiently been studied. This paper focused on three fields, i. e., manufacturing, healthcare and transportation service, investigated current status of preventive activity, compared the results and identified issues to be tackled in future. As the result, it was found that implementation level of preventive activity, activity elements that affect number of trouble/accident, and difficulties in improving the level and countermeasures for overcoming them are different in these three fields, and therefore approaches that depend on situations in each field are needed to promote preventive activity further more.
