Research on Emergency Response Evaluation of Major Process Safety Accidents

摘要

The major accident emergency is the last line of defense for process safety control.In this paper,an evaluation index system for emergency response capacity of chemical accidents based analytic hierarchy process(AHP) method was established,according to the four different stages of major accident emergency in chemical process including precaution phase,preparation phase,response phase and recovery phase.By analyzing the weight of different index in evaluation index system,fuzzy comprehensive evaluation method was used to solve the quantification of the emergency response ability of major accidents as well as the protection analysis more completely of the chemical process.Through the study of these comprehensive safety technologies and the implementation of relevant technical measures,the emergency response capability of major chemical accidents can be improved and the safety risks during the production of hazardous chemicals can be reduced.The major accident emergency system is the last defence of process safety control.To improve the ability to respond to major accidents and establish a quick and efficient emergency response system is helpful to prevent and control accidents and to reduce the risk of the process safety accidents[1].When enterprises face a variety of emergency situations,different emergency services lead to very different consequences for the enterprises^.At present,one of the important reasons for the frequent accidents and the serious consequences of casualties in China is that the emergency response system is not perfect and the emergency response capability of enterprises is insufficient.The purpose of the emergency capability assessment is to find out the problems and weaknesses in the normal work of emergency management and to improve and perfect the enterprise emergency management system[3].In order to strengthen and perfect the emergency management work,enterprises should focus on improving the ability to prevent and handle unexpected incidents and effectively supervise,inspect and promote the-daily emergency management work according to the characteristics of internal and external assessment so as to enhance emergency response management capabilities,and comprehensively strengthen the emergency management system[4].
