Abstract:

Objective To comprehensively evaluate the occupational disease hazard factors and their degree,the impact on workers' health and occupational health management in the workplace of a special equipment manufacturing enterprise in Tianjin,point out the main problems,and put forward measures and suggestions. Methods According to the characteristics of occupational hazards in a special equipment manufacturing enterprise,through the retrospective analysis of the survey data,the exposure level of occupational hazards,occupational disease prevention and protection and occupational health management of the workers in the enterprise were comprehensively understood. Results The occupational hazard factors in the production of the special equipment manufacturing enterprise mainly included noise,welding dust,grinding wheel dust,nitrogen oxide,ozone and so on. In this test,there were 35 individual noise samples,81 fixed-point noise samples,67 individual chemical hazard samples,and 94 fixed-point chemical hazard samples. The individual noise measurement results of welders and riveters exceeded 85 dB(A),and the workplace noise measurements up to 104.0 dB(A). The highest detection result of grinding wheel dust was 9.7 mg/m3,the highest detection result of electric welding dust was 11.5 mg/m3,and the detection results of other chemical harmful factors and physical factors were in line with the requirements of national occupational health limits. Conclusion The special equipment manufacturing enterprise has a certain mechanized and automated production process,and the occupational hazard factors are mainly concentrated in welding,grinding,cutting,painting and other operations. It is suggested to strengthen the maintenance and rational use of ventilation and purification devices,track the results of occupational health examination of workers in time,urge workers to wear personal protective equipment correctly,and further improve the level of occupational health management.
