基于层次分析法的高校化工实验室不安全行为研究

Research on Unsafe Behaviors in Chemical Laboratories of Universities Based on the Analytic Hierarchy Process

为预防高校化工实验室安全事故,运用层次分析法对高校化工实验室不安全行为影响因素进行风险评估与分析。评估过程主要从组织,个人和环境三个方面来分析对实验不安全行为的影响。根据客观性、通用性和适用性原则建立高校实验室不安全行为影响因素模型。通过计算三个方面的影响因素的下层指标权重值来评估各因素对实验不安全行为的影响。结果表明,实验习惯方面的权重值0.471 3是最高的,是影响实验不安全行为的主要因素,同时安全设施、实验室安全检查、安全知识、安全意识等因素是较为重要的。基于层次分析法的评估结果能够为高校实验室不安全行为的改善提出参考。

In order to prevent safety accidents in chemical laboratories in colleges and universities,a hierarchical analysis is used to assess and analyze the risk of factors influencing unsafe behaviors in chemical laboratories in colleges and universities.The assessment process mainly analyzes the influence on laboratory unsafe behaviors from three aspects:organization,individual and environment.According to the principles of objectivity,generality and applicability,a model of influencing factors of unsafe behaviors in college laboratories is established.The influence of each factor on laboratory unsafe behavior is assessed by calculating the weight values of the lower indicators of the influencing factors of the three aspects.The results show that the weight value of 0.4713 for the aspect of experimental habits is the highest,which is the main factor affecting experimental unsafe behaviors,while the factors of safety facilities,laboratory safety inspection,safety knowledge,and safety awareness are more important.The assessment results based on the hierarchical analysis method can suggest a reference for the improvement of unsafe behaviors in college laboratories.
