An Inherent Safety Implementing Approach for Safety Planning of Chemical Industrial Parks in China

摘要

In the last two decades chemical industrial parks have developed greatly in China. Due to lack of sufficient safety planning technologies, many problems have been brought about to dramatically cause hazards,which could not be amended or may cost too much money to make up .Although there are some related technologies in foreign countries,some factors affected their application in China,such as lack of foudamental data, difference of management mechanism and equipment quality.In this paper, statistics of main accidents in Chinese chemical industrial parks were carried out to study accident process mechanism and risk characters, from which impact parameters were picked up. Based on the validation of the information about the impact parameters, the lifecycle of a chemical industry park was divided into several stages.Safety planning targets of each stage were figured out in the view of inherent safety theory.Considering the current state of chemical industrial parks in China, quantified indice for former targets and achieving strategy were dicussed, then models were built to assess the quantified indices.
