基于突变评价法的化学实验室安全状态分析

Safety status evaluation of chemical laboratory based on catastrophe evaluation method

为提高化学实验室安全管理水平,遏制重特大事故发生,采用突变评价法对实验室关键安全状态进行定量分析。通过对化学实验室安全状态影响因素的辨识,建立了化学实验室安全状态影响指标体系,构建了化学实验室安全状态突变评价模型,并采用分值变换的方法对突变模型中安全状态值进行处理,增强了评价结果的准确性和客观性。将构建的突变模型应用至某工业园区内71家化学实验室整体安全状态分析中,结果表明:该方法可以较客观地评价实验室的安全状态,并有效地辨识出当前影响化学实验室安全状态的主要因素,为实验室安全管理工作提供指导。

To improve the safety management level of the chemical laboratories and curb the occurrence of the serious accidents,quantitative analysis of key safety states is carried out based on the mutation evaluation method.By identifying the factors influencing the safety status of the chemical laboratories,we established a chemical laboratory safety status influence index system,constructed a chemical laboratory safety status mutation evaluation model,and processed the safety status values in the mutation model by using the method of score transformation to enhance the accuracy and objectivity of the evaluation results.The results show that the method can effectively identify the main factors affecting the safety status of the chemical laboratories and evaluate the safety status of laboratories more objectively.
