Abstract
Problems in incident survey and analysis in Japan are discussed and a new method of ‘survey and analysis of presumed accidents’ is proposed. The survey is conducted with an anonymous questionnaire method on workers in 3 Japanese Railways factories. Workers are asked to describe the presumed accident to which the highest priority of measures should be given, and the accidents are analyzed statistically. As a result, it is shown that an accident pattern can be selected to focus on in safety management. This method can be used for substantial preventive safety management based on features of workplaces.
