某铝幕墙制造项目职业病危害预评价

Pre-Evaluation of Occupational Hazards in the Construction Project of Aluminum Curtain Wall

目的识别、评价某铝合金幕墙制造企业建设项目可能存在的职业病危害因素,探讨防护对策和管理措施。方法按照《建设项目职业病危害评价规范》要求,采用类比法、经验法和检查表法对该项目的职业病危害进行预评价。结果该建设项目的选址与总体布局、生产工艺和设备布局、建筑卫生学、个人防护用品、职业病防护设施设计、辅助卫生用室等符合国家有关规定;应急救援,职业卫生管理方面存在不足,生产过程中可能产生粉尘、毒物、噪声、电焊弧光等主要职业病危害因素。类比企业噪声共检测8个点,其中雕刻机噪声强度87〔dB(A)〕不符合职业接触限值,合格率为87.50%。其他主要职业病危害因素均合格。结论该项目生产过程中产生的职业病危害是可以预防的,从职业卫生角度分析该项目是可行的。

Objective To identify,analyze the possible occupational risk factors and degree in this construction project,assess its feasibility in occupational disease prevention and protection,provide necessary countermeasures and advice of occupational disease hazard prevention and protection for its primary design.Methods The assessment was conducted by using combination of analogy,checklist and experience methods.Results The selection of site,the overall layout,the arrangement of the facilities,building hygiene,occupational disease prevention,facilities of auxiliary rooms,personal protection equipments and protection establishment accorded with the requirements of laws and legislation of occupational health.But this construction project was still short of the occupational health management and emergency rescue measures.Occupational risk factors might existed in the project were dust,poisons,noise and electric welding.The noise intensity of engraving machine（87 dB（A）） in analogy industry exceeded national occupational exposure limits,qualified rate of detection points was 87.50%.Other main occupational risk factors met with national standards,qualified rates were 100%.Conclusion The occupational hazards which possibly present in the project can be prevented and controlled if all the countermeasures and advice of occupational disease hazard prevention and protection are carried out.
