Research About Optimizing The Safety Risk Classified Management Mechanism Of B Beer Manufacturing Company

Comparing with the rapid growth of economic in China,accidents frequently happened in the domestic industrial enterprises in recent years.Some small and medium sized companies whose safety management is in the low level,even sacrifice the safety for their economic development.In the face of this situation,the Safety Commission of State Council comes up a new concept:a dual prevention mechanism which including the safety risk classified management mechanism and the potential danger checking and control mechanism.Government who built two "firewalls" wants to control hazards and prevent accidents,and then hazards will be wiped out before accident happened.The potential danger checking and control mechanism has come out for a long time,and companies comprehend this mechanism easily and applied it well.However,the safety risk classified management just come out in recent years,and this mechanism is abstract to understand and difficult to apply,so it is hard to promote and implement.B beer manufacturing company is a huge multinational enterprise who grasp the idea of the safety risk classified management mechanism,and carry out some this work,but it is still not satisfy this mechanism's requirement.This paper is going to do a research about how B company implement the safety risk classified management mechanism for following purposes:first,is to optimize the safety risk classified management in B company;second is to offer the reference for other companies.This research is including analyzing the safety risk classified management in this company,pointing out the problems and reasons,and perfecting this management by using PHA and Mood Index to identify and assess the hazards,and then offering some safeguard measures.This company mainly used some simple methods like brain-storming,JHA,SCL,to identify risks,but those methods only get the simple and crud structuralization of risks,that is hard to identify all risks.To solve this problem,and based on this company's ability,this paper chose PHA to optimize this company's risk identification.Secondly,this company chose method LEC to assess risks,but in the liquid ammonia refrigeration plat,LEC which only has 3 index,is not suitable to present very danger and complex hazard,so this paper chose Mood Index,which offers accuracy hazard value for Hazardous chemical process,as the assessment method.Thirdly,in the practice of the safety risk classified management,B company does not meet the requirement,because it is lack of safety risk classified management system,and does little about how assessment result using.In this paper,B company need to optimize the system and institution.To make sure all this suggestions implement and achieve the effect,this paper also point out 4 safeguard measures:company's management system,institution,fiance,education.This paper also points out that the government need to perfect the government safety risk classified management guide.The guide shouldn't limit the risk identification and assessment methods among JHA,SCL,LEC,Risk Matrix.Some reliable and effective methods such as PHA,FMEA,HAZOP,Petri Net should be highly commanded.The guide should focus more on the implement of hazard assessment results.
