基于模糊综合评价法的作业现场纳米二氧化钛职业危害评价研究

Evaluation of occupational hazards of nano titanium dioxide in job site based on fuzzy comprehensive evaluation method

随着纳米二氧化钛材料的广泛应用,作业现场纳米二氧化钛生物安全性问题也逐渐引起人们的重视。为了能够合理评价作业现场纳米二氧化钛职业危害水平,为作业现场纳米二氧化钛职业危害防控提供参考,本文综合考虑纳米二氧化钛生产过程的整个周期,从人、尘、环、管四个层面着手,建立由4个一级评价指标、10个二级评价指标和31个三级评价组成的评价指标体系,并运用层次分析法确定指标权重;结合模糊综合评价法,提出了作业现场纳米二氧化钛职业危害综合评价模型,并通过现场运用验证其合理性。

With the wide application of nano - titanium dioxide materials, the biological safety of nano -titanium dioxide on the job site has gradually attracted people＇s attention. In order to reasonably evaluate theoccupational hazard level of nano-titanium dioxide on the job site and provide reference for the occupationalhazard prevention of nano-titanium dioxide, this paper comprehensively considers the entire cycle of nano-ti.tanium dioxide production process. The paper starts from the four levels of human, dust, environment, andmanagement, establishes an evaluation index system composed of four first -level evaluation indicators, tensecond-level evaluation indicators, and 31 third-level evaluations, and uses the analytic hierarchy process todetermine the index weights. Then combined with the fuzzy comprehensive evaluation method, a comprehen,sive evaluation model of occupational hazards of nano-titanium dioxide on the job site was put forward, and itsrationality was verified through field application.
