一种简单可行的危险化学品重大危险源分级方法

对3种常用危险化学品重大危险源分级方法进行比较研究。提出采用危险化学品重大危险源单元内各种危险化学品的总量与其临界量比值经校正系数校正后的值R作为分级指标的危险化学品重大危险源分级方法。给出R的计算方法、相关校正系数的选取标准,以及危险化学品重大危险源的分级标准。通过笔者危险化学品重大危险源分级方法的实际应用,其结果表明:该方法简单可行,具有一定的科学性和较好的可操作性,能满足危险化学品重大危险源分级的需要。

A Simple and Feasible Grading Method for Major Dangerous Chemical Hazard Installations

The grading method is very important in the safety supervision and administration of major dangerous chemical hazard installations. Through a comparative study on three common methods used to grade major dangerous chemical hazard installations, a new grading method is proposed in which R is a grading indicator. In this method, R is calculated by the ratios of different chemical quantities and their threshold quantities in the unit after correction of chemical categories and numbers of people. This method is applied in one enterprise and the results show that it has a certain degree of science and better operability, and can meet the need of the grading for major dangerous chemical hazard installations.
