Safety And Health Evaluation And Control Research Of An Automobile Painting Shop

In recent years,automobiles have increasingly become an irreplaceable means of transportation,and their speed of diversification and replacement has become faster and faster.Automotive painting is an important part of automobile production.The occupational hazards cannot be ignored.Creating a healthy working environment is of vital importance to both the company and the staff.In addition,within the scope of the automotive manufacturing industry,people are gradually paying attention to related safety issues and occupational health issues.Automotive painting is a complex process that produces frequent accidents in the field of painting operations.Due to the toxic and hazardous materials involved in the process,various risk factors and harmful factors coexist.Harmful factors such as poisoning,noise,vibration,fire,electric shock,etc.may cause occupational diseases or even life-threatening injuries.Therefore,it is necessary to properly evaluate the safety and health issues of the paint shop and propose corresponding control measures.This paper conducts safety evaluation based on the working condition of an automobile painting workshop,and numerically simulates the wind flow field in the workshop.Comprehensive paper work,the conclusions are as follows:(1)Through the identification of the working environment,raw and auxiliary materials and operation procedures of an automobile painting workshop,and using the improved LEC method for the workshop,the results show that the workshop has fire and explosion,mechanical damage,electric shock and The risk of poisoning asphyxiation.The most dangerous processes include paint mixing work room,painting work room and drying room.The value of L in the classical LEC method is very subjective.This paper combines the possibility of accidents in the paint shop with the relationship between people,machine,ring and management,and introduces the corresponding possibility factors to make the risk.The evaluation results are more objective and fair.(2)Through the occupational health investigation and on-site sampling and testing of the painting workshop,identify and evaluate the existing occupational hazard factors,and evaluate the occupational disease prevention facilities and occupational health protection products used by the individual in the workshop.Occupational hygiene test results show that the exposure level of xylene occupational hazard in the electrophoresis feeding station of the painting workshop does not meet the relevant national limit requirements.(3)For the phenomenon that the exposure level of xylene occupational hazard in the electrophoresis feeding station encountered in the actual work was exceeded,the FLUENT was used to simulate the local wind flow organization of the electrophoresis feeding station.The results showed that the vertical inlet was used.In the way,there is a phenomenon that the position of the electrophoresis feeding position is no wind or weak wind around the edge of the electrophoretic painting operation,which is not conducive to the airflow exchange in the workshop,so that the toxic and harmful substances in the workshop cannot be discharged in time.(4)In view of the shortcomings of the original ventilation system,the grid inclined air inlet is designed to optimize the wind flow field of the workshop.The simulation results show that the inclined air inlet can effectively improve the electrophoresis feeding position of the electrophoresis painting operation.Airflow organization...
