With the deepening of teaching reform and the growth of scientific research strength, the safety situation faced by the laboratory for teaching and scientific research is becoming more and more serious. All sectors of society carry out work in different aspects for laboratory safety. Nevertheless, laboratory safety accidents still occur as before from time to time in universities and institutes. In fact, each accident not only relates to the laboratory safety management rules but also relates to the content of experiment project itself. This requires the organizers of experiment projects or relevant scientific researchers to take some actions. The risks involved in the whole process of the experimental project should be analyzed. If these risk analysis cases are collected and formed into a case base, it must be an effective means to reduce the occurrence of accidents and reduce the harm of the accidents. This work will play an important role in laboratory safety management and high-quality talents cultivation.
