A Banknote Printing Enterprise Gravure Printing Process Hazards Identification And Control Countermeasures

Banknote printing enterprise production process used by the gravure printing technology is the key to the banknote printing process is different from the general printing process.For gravure printing printing pressure,printing ink dosage is large,heavy use of clean version of the fluid and the lack of the study of the safety risk precedent and choose to gravure printing process hazards identification and control countermeasures as the research object,to seize the banknote printing enterprise security risk management of weak links,and scientific evaluation of the security risks of gravure printing process,in view of the main risk control measures are put forward and the improved method,in order to improve the safety of the gravure printing process to provide a set of targeted solutions.In this paper,the principle and method of safety system engineering,the gravure printing equipment,technology and raw materials were analyzed,and the risk matrix method is adopted to preliminary analysis and determine possible risk,find out the equipment itself the hazards and hazards caused by occupational hazards in the environment,and use the risk matrix to find the preventive issues for further analysis.Aiming at the equipment itself in preventive problem of hazards,graham evaluation method evaluation method(LEC)of semi-quantitative risk assessment,to determine the degree of printing machinery injury risk belongs to significant risk,for its build the fault tree,using FTA analysis,find out the path set,determine the structure importance,it is concluded that the basic cause of the accident events on the impact of the top event.For preventive problem in the working environment of occupational hazards caused by hazards,according to the work sites and distribution,determine the sampling points,the microporous membrane filter method(sodium hydroxide)and activated silica gel adsorption test,determine the harmful substances and physical factors of the existence of the average value,by the method of occupational health risk assessment of MES,all kinds of hazard risk assessment,and determine the priority order.According to the path sets and structure importance analysis results,and puts forward the roller printing process safety protection device normal use security measures,such as the problems and solutions;According to the result of risk assessment of MES,priority to noise harm to make occupational hazard control measures are put forward,and the appropriate to control harmful material such as isopropyl alcohol harms way.Through the formulation and implementation of controls,the gravure printing process to effectively control the main security risks,avoid because of the risk identification and control does not reach the designated position,risk into a hidden danger for the development of accident or even the occurrence of occupational diseases,and so on and so forth.
