半定量与定量模型在光纤制造企业风险评估的比较研究

A comparative study of semi-quantitative and quantitative models in risk assessment of optical fiber manufacturing enterprises

摘要:

目的探讨半定量与定量风险评估模型用于光纤制造企业化学危害因素接触评估的结果、可行性及其存在的问题。方法 对武汉市1家光纤企业化学危害因素进行调查、检测和评价，并应用工作场所化学危害因素职业健康半定量与定量风险评估模型进行风险评估。结果 半定量风险评估模型中接触指数法与综合指数法的评估结果一致性极好（Kappa=0.820，p＜0.01），结果为2-3级；接触比值法与E/OEL关联性较大（r2=0.539，P＜0.05），结果为1、2、3、5级。定量风险评估模型中非致癌风险危害商数与半定量的3种方法一致性较差（Kappa=0），结果为1、2、3、4、5级。结论半定量风险评估模型较定量风险评估模型更适用于光纤行业的风险评估。

Abstract:

Objective To explore the results, feasibility and existing problems of semi-quantitative and quantitative risk assessment models in the assessment of chemical hazard exposure in optical fiber manufacturing enterprises. Methods The chemical hazard factors of an optical fiber enterprise in Wuhan were investigated, detected and evaluated, and the semi-quantitative and quantitative risk assessment models of occupational health of chemical hazard factors in the workplace were used for risk assessment. Results In the semi-quantitative risk assessment model, the consistency between the contact index method and the comprehensive index method was good (Kappa=0.820, P<0.01), and the result was grade 2-3. The evaluation results of the contact ratio method were significantly correlated with those of E/OEL (r2=0.539，P<0.05), and the results were grade 1, 2, 3 and 5. The non-carcinogenic risk hazard quotient of the quantitative risk assessment model was not consistent with the three semi-quantitative methods (Kappa=0), and the results were grade 1, 2, 3, 4 and 5. Conclusion The semi-quantitative risk assessment model is more suitable for the risk assessment of the optical fiber industry than the quantitative risk assessment model.
