摘　　要：目的探讨学生实验室安全知识盲区,以提高高校实验室安全管理工作的成效。方法考试人数192人,共计235次考试,根据考试系统的统计分析结果,观察各题目错误率和各选项构成比;结合统计描述和χ^(2)检验,探讨影响学生实验室安全考试成绩的原因和所存在的知识盲区。结果41%的考生身份为在读硕士研究生,59%的考生为在读本科生,男生占48%,女生占52%,且比较不同身份的性别构成比,差异无统计学意义;题目被归纳分为“行为规范”“应急自救技能”和“事故防范能力”三大部分,比较“行为规范”和“应急自救技能”类题目的错误率,差异存在统计学意义(χ^(2)=7.570,P=0.006),“应急自救技能”类题目的错误率为3.14%,高于其余两类。结论高校学生对应急自救技能类可能存在较多的知识盲区,应以之作为实验室安全管理工作关键控制点,加强应急自救技能培训可以极大地降低事故的严重程度。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(χ^(2)=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.
