目的:探讨类比法在职业病危害预评价中的综合应用。方法:根据建设项目生产过程中可能产生的职业病危害及其特点,选择类比厂和装置,对类比对象与拟评价项目进行类比调查和分析,并根据分析和调查结果进行评价。结果:通过对建设项目和类比厂的一般情况和防护措施的类比,显示两者的职业病危害因素具有相似性。与类比厂相比,建设项目的防护措施仍有待加强。结论:通过对该项目类比厂的资料调查及现场检测,较好地预见了建设项目的实际情况,预测出该厂的职业病有害因素及危害程度,为制订合理的职业病防护措施提供依据。
Objective: To explore the application of analogy in pre-evaluation of occupational hazards. Methods: Based on the occupational hazards and their characteristics that may occur in the production process of construction projects, analogy plants and devices were selected to carry out analogy survey and analysis on analogue objects and proposed evaluation items and evaluated according to the analysis and investigation results. Results: Through the analogy of the general situation and protective measures of construction projects and analogy factories, it shows that the occupational hazards of the two are similar. Compared with the analogy factory, the protective measures of the construction project still need to be strengthened. Conclusion: Based on the data investigation and on-site inspection of analog plant in this project, the actual situation of construction project is forecasted, the harmful factors and hazard degree of occupational disease are predicted, and the basis of reasonable occupational disease protection measures is provided.
