Recently, the industrial accidents rate of young unskilled workers is increasing in our country. Therefore, in national institute of technology which produces young engineers, an effective safety and health education for these workers is also desired strongly. Action to collect near-miss incident information is important position in such education. However, the near-miss reporting is not functioning effectively at the majority of national institute of technology because of negative consciousness and lack of understandings about this activity. In this research, we proposed the teaching method about the near-miss reporting using minority influence in order to solve these issues and carried out this method for three years from 2015 at our school. In this paper, we showed that injury accidents and tool breakages decrease as student near-miss reports increase, and safety culture maturity level in the mechanical workshop rises.
