Objective To enhance the efficiency of laboratory safety management in colleges,we analyzed the insufficiency of students in the knowledge about laboratory safety. Methods A total of 192 college students had attended the education tests of laboratory safety and totally 235 tests had been successfully recorded．According to the statistical analysis results,we observed the error ratio and the and the composition of the options for each question in the tests．With statistical description and Chi-square test,the impact of the test scores and the main insufficiency in the knowledge about laboratory safety were discussed. Results 41% of the students were pursuing master's degree,59% of them were pursuing bachelor's degree,48% are males and 52% are females,there was no significant difference in gender composition among different identities．All the questions had been categorized into three types,which were principle for conduct in laboratory,the skills of self rescue and the capability to prevent accidence．There was statistical significance between types of questions on principle for conduct in laboratory and the skills of self rescue（χ²=7.570,P=0.006）,the error ratio of the question type of skills of self rescue was 3.14%,which was higher than the other types. Conclusions The insufficiency in the knowledge of skills of self rescue might probably be the critical control point in laboratory safety management,which should set as the key point of lab security,improve the self rescue skill of students may decrease thu severity accidence．
