某化工企业事故隐患分析与安全评价(2)
The analysis on potential risk and safety assessmentof chemical enterpriseTotal description: Chemical industry not only leads to the development of economyand our life is becoming more and more inseparable from the chemical products.Allkinds of chemical enterprises are flourishing, the scale of increasing security hiddendanger is growing at the same time. Especially small and medium enterprises, theoverall hardware level lags far behind the large enterprises, personnel safetyconsciousness, lack of enterprise safety culture and other objective factors greatlyincrease the probability of the accident. So chemical companies must understand thehidden trouble in security companies, and reduce and avoid the occurrence of safetyaccidents from the source, then The analysis on potential risk and safety assessment isparticularly important.This design with specific chemical industry enterprises as the research object, theanalysis on potential risk and safety assessment. Before safety assessment, throughconsulting a large number of literature, the general situation of the safety assessmentof development both home and abroad do the sorting summary. Abroad, safetyassessment technology in the early 1960 s made great development, and then appliedin various fields and constantly improve. In our country, by absorbing and digestingforeign knowledge, we have a very big breakthrough in the field of safety assessment.Over the past few years, with the development of economy and emphasis on safety,we issue a series of safety laws and regulations.Safety assessment of the main content is: firstly to the general situation of chemicalenterprises, the main products including production, production process, dangerouschemicals production and raw and auxiliary materials consumption. Later,respectively from the risk of material itself, the risk of production process, storageprocess three aspects has carried on the risk of dangerous and harmful factorsidentification. In addition, from the people, machine, environment and management ofthese four aspects put forward the problems existing in the enterprise.There are many kinds of safety assessment about chemical enterprise. It can bepided into qualitative and quantitative safety assessment method. This design usesthe qualitative method of safety assessment is the preliminary hazard analysis (PHA),quantitative safety assessment method for fault tree assessment method (FTA), DOWchemical fire explosion hazard index assessment method (DOW). In addition, usingthe combination of qualitative and quantitative fuzzy hierarchy comprehensiveassessment method do safety assessment for the chemical industry. Risk analysismethod is mainly used in advance details haven't master system, analysis andidentification of possible or existing hazards, and before put into practice to find outas much as possible prevention, correct, remedies, to eliminate or control hazards.Fault tree analysis method can not only analyze the direct cause of an accident, butalso deeply reveal the underlying causes of the accident. Use it to describe thecausation of the accident intuitive and clear; Clear and logical. Fuzzy assessment through precise Numbers means dealing with fuzzy assessment objects, to containinformation presented fuzzy information to make more scientific, reasonable, and thequantitative assessment of press close to actual. Because the chemical enterprise ismajor hazard source. It exists safe hidden danger of fire and explosion, and thepolarization method after seven version of the revision has been mature, so using thismethod for safety assessment.Later, by combining the environment analysis of the impact on the safety, it is a greatinnovation of this article. The conclusion is that the chemical enterprises will not havea significant pollution, so the environment factor will not have big impact on safety.The last is the summary of this paper and prospects of safety assessment for thefuture.Through analyzing the chemical enterprise’s accidents and safety assessment, theconclusion is: in the production process or equipment in the event of error may causeaccidents, which in a lot of material leakage, cracking reaction, polymerization is outof control and rectification in the event of fire explosion accident consequences aremost severe. Once the inside of the equipment layout is dense, tank farm in thestorage tank is decorated also relatively dense, the accident would extend to the entiredevice or tank farm. So you need to man, machine, environment and managementfrom the four aspects carry out a series of corrective actions.The enterprise needs to do safety orientation for employees. For example, they mustattach importance to the tertiary education, increase the safety awareness ofemployees on thought, cognition of the importance of employees to wear PPE; Andthe operation training on a regular basis will notice, standardized operation process toinform employees; Regular fire drills and exercises of leakage of dangerous chemicals.Staff can have emergency response in the first place, It will minimize the damage toitself and the enterprise with minimal damage to property; Learning study in everymonth is needed in order to check potential risk in the process and improve theaccident emergency plan, etc.If the enterprise is not willing to invest the money on the safety, or doesn't implementthe safety. All materials are to cope with government departments to check andprepare, so enterprise future development road doomed not to long term. Chemicalenterprise safety involves the personal safety and social stability. safety is a long wayto go. It requires each department and everyone's cooperation. In the development ofthe future,I hope that enterprises really attach great importance to the safety, theemployee's health and safety in the first place.
