某重工企业生产建设项目职业病危害控制效果评价

目的识别、分析和评价某重工企业生产建设项目存在的职业病危害因素及其防护控制效果，为企业提出进一步控制职业病危害的措施。方法采用职业卫生调查和现场检测等方法，对建设项目职业病危害进行综合性分析评价。结果该项目为职业病危害严重的建设项目，在总体布局、生产工艺设备、防护设施和职业卫生管理等方面基本符合相关要求，但电焊等尘毒作业点多，不固定，分布广，不易采取防护措施。锰及其无机化合物、一氧化碳、苯、电焊尘等粉尘、紫外辐射和噪声有不同程度的超标。结论该企业必须进一步加强职业病危害的防护控制，建议改进生产工艺，增加电焊、涂装、打磨等关键控制点防护设施，同时加强劳动者的个人防护。

Evaluation on control effect of occupational hazards in a construction project of heavy industrial enterprise

Objective] To identify, analyze and evaluate the occupational hazards and protective control effect in a construction pro- ject of heavy industrial enterprise, provide the basis for further control measures of occupational hazards. Methods] By using the occupational health survey and on-site detection, the comprehensive analysis and evaluation of the occupational hazards was conduc- ted. Results] The occupational hazards are serious in this construction project. The overall layout, production equipment, protec- tive equipment and occupational health management are accordance with the relevant requirements basically. However, the protec- tive measures for welding dust are difficult to implement because the welding operation points are abundant and unfixable, and dis- tribute widely. The concentration of manganese and its inorganic compounds, carbon monoxide, benzene, welding dust, ultraviolet radiation and noise exceeded the limits in different degrees. Conclusion] The enterprise must further strengthen the protective con- trol of occupational hazards. It is recommended to improve the production process, increase the protection facilities on the critical control points of welding, painting and grinding, and improve the personal protection of workers.
