RESUMO
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, P2=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.
