Application And Study Of The Theory Of Accident Causation In Chemical Enterprises Satety

With the situation of chemical companies frequent accidents, this text research and use a variety of qualitative and quantitative evaluation methods to make safety evaluation. Through the dangerous and harmful factors to lead to the accident, the text analysis the severity level and classes of the hazard, and make the necessary safety control measures to achieve the purpose of accident prevention and advance control.The first, base on the research of safety assessment and the theory of systems security engineering, this text make classification statistics to the major chemical companies typical accident, and use system security analysis from the staff, machinery and equipment, environmental and regulatory, then further summarize the kind and identification objects of hazardous factors in chemical companies.Analyze and summarize the research and application of the safety evaluation technology at home and abroad. According to the modern accident causation theory, this text summary and analysis a variety of methods of safety assessment and compare their advantages and disadvantages. By selecting the evaluation method which best corresponds to the system unit, this text determine the risk characteristics and damage for the accident risk and high frequency factors, and ultimately establish the control measures and safety evaluation mode. So it makes a full, specific and reasonable safety evaluation work to supplement the domestic defect today.To the characteristics and the risk of chemical companies, this text uses a variety of evaluation methods to qualitative and quantitative analysis of its dangerous and harmful factors, and to determine the direct and potential factors, in particular the identification of major hazard. On the basis of the proposed methodology and safety evaluation mode, it carries on safety evaluation to Yan-Jing Brewery Co., Ltd. technological transformation. Theory with practice, the result is true, evaluation methods are reliable, and preventive measures is reasonable, which have a certain role in promoting the safety and production.It is extremely important to use the integrated safety evaluation methods in chemical industry; these methods can be an effective identification to the direct and potential factors in system that determines the degree and level of risk. And ultimately propose appropriate control measures so that prevent accidents. As for building site, layout and process equipment, it is necessary to upgrade technology, enhance safety management, personnel training and public education, and ultimately realize the safety production of chemical companies.
