Safety management for flammable hydrogen gas at Ito campus, Kyushu University is introduced. Since various research projects related hydrogen energy have been going on, for example, the safety infrastructure with hydrogen supply and exhaust systems using sensors and alarms is installed. Besides safety control in terms of facilities, International Research Center for Hydrogen Energy gives an annual training program on hydrogen safety for students, faculty members, and other university staffs. As another tool to develop a safety environment for experiments, submission of “near-miss report” is obligated when a minor accident occurs. Based on the collection of “near-miss report” for 10 years, tendencies of minor accidents and safety measures are analyzed and discussed in detail.
