				        	Objective:To evaluate the risk of major chemical exposure positions in copper and nickel smelting enterprises, and provide a basis for risk assessment and prevention control measures.Methods:From September to October 2023, two copper nickel ore smelting enterprises in Xinjiang Uygur Autonomous Region were selected as the research objects. Relevant information on chemicals was collected through occupational hazard field investigations. Qualitative analysis and exposure index methods were used in GBZ/T 298-2017 "Technical Guidelines for Occupational Health Risk Assessment of Chemical Hazardous Factors in the Workplace" to conduct risk assessments on the main chemical exposure positions. The qualitative risk assessment results were checked for consistency using the Weighted Kappa coefficient.Results:The positions with high risk of exposure to hazardous chemicals in copper nickel smelting enterprises are saponification positions exposed to hydrochloric acid in refining processes, black nickel positions exposed to sodium hydroxide, and tail suction positions. The consistency between the two occupational health risk assessment results is poor (Kappa=0.14) .Conclusion:The amount of major hazardous chemicals in copper-nickel smelting enterprises is large, and the occupational health risks caused by exposure are complex and diverse, so the effects of chronic occupational health should be strengthened.
