实验室安全与风险评估常用方法讨论

A Discussion on Normal Assessment Methods Related toSafety and Risk in Laboratories

为提升实验室的安全水平,需对各类实验室风险进行科学评估,制定出有针对性的预防措施和应急预案,降低实验室风险。文章分析了目前常用的矩阵法、风险优先指数法、量规法、风险树法、层次分析法、LEC法、大数据法等几种评估方法的特点及其优缺点。分析结果显示,大数据法是目前对实验室风险评估方法中精度高、耗时短的方法。在实际工作中可根据各个实验室的具体情况选择适当风险评估方法。

It's necessary to assess scientifically risks in various laboratories in order to improve their safety.The corresponding measures and emergency plans should also be made to lower the risks in the laboratories.At present,there are many normal assessment methods,such as matrix method,risk priority index method,gauge method,risk tree method,analytic hierarchy process,LEC method and big data method.Features,advantages and disadvantages of these assessment methods are analyzed in this paper.The results show that big data method is high in degree of accuracy and low in the consuming of time.In reality,appropriate risk assessment methods can be selected according to the specific situation of each laboratory.
