Abstract：Objective To explore the applicable conditions and applicability of qualitative risk assessment，synthesis index method and International Council on Mining and Metals（ICMM）matrix method by application of painting produced enterprises.Methods Occupational Hygiene Investigation Method was used to investigate the exposure of organic solvent types，contact conditions and occupational disease prevention measures for the inspection positions of 4 painting produced enterprises；Detected 8-hour average contact concentration of post used inspection test method；assessed the occupational heath risk level of inspection worker used qualitative risk assessment，synthesis index method and ICMM matrix method. Compared the assessment results after converted by ratio method.Results The organic solvents contacted by inspection positions of 4 paint manufacturing enterprises are benzene，toluene，xylene，styrene，ethyl acetate，butyl acetate，toluene diisocyanate（TDI），methyl methacrylate，isopropyl alcohol，Butanol and acetone. The risk classifications of hazard factors in the qualitative risk assessment method are B-E grade，the exposure classifications are 2-3 grade，the risk grade assessment results are 2-4 grade；The risk classifications of synthesis index method are 2-5 grade，the exposure classifications are 2-3 grade，risk grade assessment results are 2-4 grade；the health consequences of the ICMM matrix method described as 2-4 grade，the exposure possibility may be high，medium and low，and the risk assessment results are 1-4 grade. The risk level of qualitative risk assessment method is higher than or equal to the synthesis index method and ICMM matrix method. When the on-site detection concentration is higher than the occupational exposure limit（OELs），the ICMM matrix method result is higher than or equal to the synthesis index method，lower than or equal to the synthesis index method results if the on-site detection concentration is lower than action level（1/2 OELs）. The assessment results of three methods are consistent when high toxic substances with the on-site detection concentration exceeds the OELs and low toxic substances with the on-site detection concentration is lower than 1/2OELs.Conclusion The occupational health risk assessment results of three methods for a certain risk factor are not completely consistent. When the exposure concentration exceeds the OELs，the ICMM matrix method and the qualitative assessment method are more conservative. When the exposure concentration is lower than 1/2 OELs，the synthesis index method and the qualitative assessment method are more conservative.
