【Abstract】 [Objective]To identify the occupational hazard in production process of a chicken flavor production enterprise in Beijing, analyze the harm degree, and evaluate the effect of occupational protection facilities and occupational health control measures. [Methods]Occupational health test, occupational health field investigation and occupational health examination were used to evaluate the current situation of occupational hazards. [Results]The 8-hour time weighted average concentrations of other dust in workplace were 0.51-7.12 mg/m3, which met the requirements of occupational exposure limits. The 8-hour equivalent sound level of turnover machine operators,tinning workers and labeled workers was respectively 88.9 d B(A),88.3 d B(A)and85.1 d B(A),which exceeded the requirements of occupational exposure limits.[Conclusion]The main occupational hazard in the production process of chicken flavor is steady noise, and it is necessary to strengthen comprehensive noise reduction measures.更多还原
