ABSTRACT

This paper aims to understand the occupational disease hazards in the production process of a steel structure production enterprise in Shaanxi Province, and to propose corresponding measures to protect workers' health. Occupational disease hazards in a steel structure production enterprise in Shaanxi Province include chemical hazardous factors and physical factors. The time-weighted average permissible concentrations of welding fume, other dusts, manganese and its inorganic compounds, nitrogen oxides, carbon monoxide, benzene, toluene, xylene, ethylbenzene, ethyl acetate, and butyl acetate are as follows: 8mg/m3, 4mg/m3, 0.15mg/m3, 5mg/m3, 20mg/m3, 6mg/m3, 50mg/m3, 50mg/m3, 100mg /m3, 200mg/m3, 200mg/m3; The permissible short-time exposure concentrations of nitrogen oxides, carbon monoxide, benzene, toluene, xylene, ethylbenzene, ethyl acetate and butyl acetate are 10mg/m3, 30mg/m3, 10mg/m3, 100mg/m3, 100mg/m3, 150mg/m3, 300mg/m3, 300mg/m3 respectively, and the test results of the above chemical hazardous factors are in line with the Occupational health requirements. The occupational exposure limit value of noise in the workplace is 85dB(A), and the noise test result of the riveter workplace is 88. 0dB(A), which exceeds the occupational health exposure limit value, and the test results of the rest of the workplaces are in line with the occupational health requirements. The exposure limit value of UV radiation is 0.24μW/cm2, and the test results of each workplace meet the requirements. Thus, the monitoring results of productive dust, chemical hazardous substances and ultraviolet radiation in the workplace of a steel structure production enterprise in Shaanxi Province meet the requirements of occupational hygiene, while the noise exposure level exceeds the limit value, and effective measures need to be taken to control the noise and effectively protect the health of workers.
