某电子制造企业扩建项目职业病危害预评价

目的针对某电子制造企业扩建项目可能产生的职业病危害因素，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，采用类比调查法对该项目的职业病危害进行预评价。结果该项目的总体布局、生产设备布局、职业病防护设施设计等符合国家相关规定；对相似企业生产过程中产生毒物、噪声等职业病危害因素检测发现，异丙醇的TWA浓度在61．5～134．5mg／m^3之间，STEL浓度在80．4～92．5mg／m^3之间，乙醇浓度均小于14mg／m^3，丙酮的TWA浓度在2．7-115．2mg／m^3之间，STEL浓度在8．1～276．4mg／m^3之间，甲基环己烷的浓度均小于1．3mg／m^3，均符合国家卫生接触限值的要求；噪声共检测11个点，检测结果在62．1～82．4dB（A）之间，无超标。该项目为职业病危害一般的建设项目。结论该项目生产过程中可能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：

Pre-Assessment of Occupational Hazards in a Wiring Manufacture Enterprise

Objective To identify and assess occupational risk factors existing in a construction project and study the preventive measures and management. Methods The pre-assessment was done by using analogy. Results The overall layout, the arrangement and layout of the facilities and the preventive and protective establishment against occupational hazards in this project accorded with the requirements of laws and legislation on occupational health. The monitoring data from similar project showed that the concentration of isopropanol, acetone and ethanol and the noise level at workplaces were compliant with national exposure limits. This construction project was ranked as a common project. Conclusion From the view of occupational health, this project is feasible.
