某散粮码头建设项目职业病危害控制效果评价

Control Effect of Occupational Disease Hazards in the Construction Project of the Bulk foodstuff Dock

目的对某散粮码头建设项目中主要职业病危害因素进行检测分析及控制效果评价。方法现场职业卫生调查、工程分析、职业病危害因素检测检验。结果粉尘个体采样检测6个工种，粉尘浓度的几何均值为0．31～30．27mg／m^3，工种合格率为50％；定点短时间检测9个岗位，粉尘浓度最高值为3．13～329．3mg／m^3，岗位合格率为11．1％；检测噪声作业点13个，合格率92．3％。结论本项目中粉尘合格率较低，通过改进，主要职业病危害因素的控制效果达到了职业卫生标准要求。

Objective To analyze and evaluate occupational hazards of the bulk foodstuff dock. Methods Field in- vestigation of health, engineering analysis and detection of occupational risk factors were applied. Results The geometric average dust concentrations of individuals were 0. 31 - 30. 27 mg/m3 , and the maximum dust concentrations of workplace were 3.13 - 329. 3 mg/m3 ; the qualified rates of dust concentrations of individuals sample and the workplace were 50% and 11.1% respectively. The qualified rate of noise was 92. 3 %. Conclusion The occupational hazards of this project is basically controlled after improvement.
