    Many accidents have occurred for students at education and research at universities, especially when involving experiments and field works. Various efforts are continuing at universities to prevent the accidents. In this study, in order to evaluate the risks of students involved in experimental works at universities, we analyzed the injury data from 2014 to 2017 from the viewpoint of an injury rate, i.e. annual number of the injured per 1,000 students, for students enrolled in Higashiyama campus of Nagoya University. As a result, the number of experiment related injuries for the students greatly depended on the enrollment year of the students, the highest at the undergraduate fourth grade and the first grade at the master course. Based on the data, we calculated the injury rate as 0.5, 4.6, 5.6 and 3.9 for four periods of undergraduate first and second grade, undergraduate third and fourth grade, master's and doctoral courses, respectively. Meanwhile,the annual rate of students' non-experimental work injury was 0.7. Using these estimations, the risk of the students enrolled for six years, i.e. four years at undergraduate and two years at master's course, was estimated as 25.6 for the students involved in experimental works. On the other hand, the risk of the student not involved in experimental works for the six years was estimated as 4.2. This means that the injury risk for the students involved in experimental works is approximately six times higher than the students not involved experimental works for their six year university life.
