PLR事故隐患分级法在上海市化工企业中的应用

PLR事故隐患分级法针对火灾、爆炸、毒物泄漏重大事故类型 ,根据事故隐患评价的基本原理 ,结合上海市事故发生及隐患普查现状 ,提出了上海市“重大事故隐患”的定义和辨识方法 ,确定了事故隐患易发性(P)、事故导致损失程度 (L)和事故后果影响范围 (R0 .5)三项评价指标 ,并将P ,L ,R三项指标组合成“PLR事故隐患分级评价表” ,由PLR事故隐患分级评价表得出事故隐患分级结果。新方法通过在上海市典型化工企业的试点应用 ,验证了PLR事故隐患分级法在化工企业中的可操作性和有效性 ,为上海市重大事故隐患的辨识、评价和整改工作提供了科学的管理方法

Application of PLR Classification Guide for Accidental Potential in Shanghai Chemical Enterprises

According to major types of accidents, such as fire, explosion and toxic release, the definition and methods of identification for “Major Accident Potential” in Shanghai were carried out in “PLR Classification Guide for Accident Potential”, following the basic principle of hazard assessment combined with the survey of accidents occurred and accident potentials in Shanghai. Combining three evaluating factors, i.e., probability (P), loss (L) and effect area (R 0.5 ) of the accidents, the “PLR accident potential classification assessment table” was proposed to indicate the consequence of accident potential classification. Through the trial application of the new approach in Shanghai major chemical enterprises, the operability and effectiveness of implementation were verified. The approach provides scientific management method in identification, assessment and improvement of major accident potentials in Shanghai.
