【摘要】：目的探索职业病危害作业分级在建设项目职业病危害预评价中的应用。方法在某拟建项目职业病危害预评价中,以建设单位已建成投产的某锂电池相关化学品生产项目作为类比项目,采用类比法结合职业病危害作业分级方法,对建设单位拟建项目锂电池电解液子项目化学危害因素及拟设置的防护设施进行分析和评价。结果拟建项目锂电池电解液子项目对应的类比项目甲A车间操作工岗位有毒作业分级为0级(相对无害作业)。预期拟建项目锂电池电解液子项目操作工岗位化学物危害程度级别、化学物职业接触比值和劳动者体力劳动强度的权重数取值均不高于类比项目甲A车间操作工岗位,有毒作业级别预期为0级(相对无害作业)。拟建项目建成投产后,锂电池电解液子项目操作工岗位接触的化学物质预期接触水平应低于职业接触限值,防护措施设置拟借鉴类比项目的经验并加以完善是合理可行的。结论建设项目职业病危害预评价中,可选择职业性接触毒物作业危害分级参数具有可比性的项目作为类比项目,采用类比法结合职业病危害作业分级方法进行分析与评价。
[Abstract]:Objective to explore the application of occupational hazard classification in pre-evaluation of occupational hazard in construction project. Methods in the pre-evaluation of occupational disease hazards of a proposed project, a project related to the production of lithium battery related chemicals, which had been completed and put into production by the construction unit, was used as an analogy project, and the method of analogy combined with occupational hazard work classification method was adopted. The chemical hazard factors and protective facilities of Lithium battery electrolyte sub-project are analyzed and evaluated. Results the grade of toxic work of operator in A A workshop was 0 (relatively harmless). It is expected that the degree of chemical hazard, the ratio of occupational exposure to chemicals and the weight number of labor strength of workers in the Li-ion battery electrolyte sub-project of the proposed project are not higher than those of operators in A-A workshop of analogous project. The toxic operation level is expected to be 0 (relatively harmless). After the proposed project is completed and put into production, the expected exposure level of the operators in the Li-ion battery electrolyte sub-project should be lower than the occupational exposure limit. It is reasonable and feasible to set up protective measures to draw lessons from the experience of the analogical project and improve it. Conclusion in the pre-evaluation of occupational disease hazards in construction projects, the items with comparable occupational exposure hazard classification parameters can be selected as analogy items, and the analogy method combined with occupational disease hazard work classification method can be used to analyze and evaluate occupational hazards.
