Research And Application On Human Factors Safety In Electricity Enterprises

The role that the power industry plays in the domestic economy determines its big differences from the other industries as regard of safety production responsibility. That is, human accidents in safety production of electricity enterprises not only affect the companies’reputation and economic profits, but also have great influence on the production, life standards and stability of the society. During recent years, the number of power network accidents in and the number of facility accidents in power industry are declining; however, the number of injuries and deaths has increased. Human is the core of safety management, the intent and the purpose of all the safety management and culture. The electricity enterprises have realized that safety human factors are the research focus of safety production in the future. In fact, there is little research on this area and most of the research focuses on the violation of regulation and errors in operation. Therefore, studying safety human factors is extremely important from both research and practice perspectives.The model of electricity enterprises safety human factors is established based on the results of Chinese and foreign literatures review and it is found that work pressure, human touch, attention, thinking ability, memory and emotional experience are most important elements by Delphi method, among which the most critical factors-cognitive ability and organizational factor are studied. The evaluability of cognitive ability is verified and the levels of sensitivity indicators are established by studying cognitive ability through safety cognitive competence and job analysis, work journal study, Delphi and instrumental measure. From the perspectives of pressure and emotion in safety strain force, the model of influencing factors of safety strain force is proved by using structural equation and conducting survey on employees in electricity enterprises and the correlation coefficient between all the influencing factors and safety strain force is calculated. It is expected that human safety capability in electricity enterprises would be enhanced by all management means with a detailed introduction of principles, developing mode, functions and technologies of employee safety promotion project.Four innovations are demonstrated in this dissertation:Firstly, safety human factor model in electricity enterprises is established based on the analysis of safety human factors. Weights of different factors were determined through TFF-AHP and then the seven main safety human factors in electricity enterprises were obtained.Secondly, it is first time those five major cognitive competences (attention, memory, perceptivity, thinking ability and imagination) are recognized and verified with rank of capability by summarizing and analyzing the research and measure data from testing of special cognitive competence.Thirdly, particular attention is paid to safety strain force in electricity. Measurement tool for safety human factors was developed into important means of measuring safety human factors in companies after careful analysis of effectiveness and reliability. The formula to quantify the relationship between safety strain force and its influencing factors was proposed and verified by statistical study.Fourthly, employee safety advanced plan was designed in accordance with China national condition and current condition in electricity enterprises in the application of safety human factor management;"people oriented" safety management mode was brought up with employee advanced planning application technology and human factor psychology emergency measures.
