Objective To evaluate the status quo of occupational hazards in a metal surface treatment enterprise by using occupational health risk assessment model issued by the International Council on Mining and Metals（ICMM）， provide basis for the risk management and control of occupational hazards in metal surface treatment industry. Methods From August 2019 to June 2020， the qualitative and quantitative assessment methods of ICMM model were used to evaluate the occupational health risk in the workplace of a metal surface enterprise. The accuracy of the occupational health risk assessment results were verified by referring to the occupational health examination results of the enterprise. Results The results of silica dust， sodium hydroxide， phosphoric acid， sulfuric acid， hydrochloric acid， toluene and xylene in a metal surface treatment enterprise by quantitative occupational health risk assessment were unacceptable， which the RR values were 8 000， 900， 900， 900， 900， 6 000 and 6 000， respectively. And the RR value of nitrogen dioxide was 18， and the assessment result was potential risk. By the qualitative assessment method， the assessment results of silica dust， toluene and xylene were high risk， while the results of sodium hydroxide， phosphoric acid， sulfuric acid， hydrochloric acid and nitrogen dioxide were low risk. The comparison of occupational health examination results and risk assessment results showed that the quantitative assessment results of sandblasting， chemical polishing and anodic oxidation positions were consistent with the results of occupational health examination， the result of qualitative assessment of sandblasting position was consistent with results of occupational health examination， and the results of quantitative and qualitative assessment of neutral positions were inconsistent with the results of occupational health examinations. Conclusion ICMM model can be applied to the occupational health risk assessment of occupational hazardous factors in the workplace of the metal surface treatment industry， and the assessment result of quantitative method is more in line with the actual situation of occupational hazards in the industry than that of qualitative method.
