Abstract: Smelting is a high-risk industry in which there are many potential safety hazards. If a safetyaccident occurs, it will bring serious consequences to the life and property of enterprises and individualsIn order to improve the scientificity and objectivity of smelting operation in safety evaluation, function andanalytic hierarchy process (AHP) are introduced to amend the evaluation method based on the traditiona.LEC. After revising the values of L, E, C and D, they are applied to the risk assessment of aluminumand iron production in a smelting enterprise. The results show that the value of D calculated by the meth.od of AHP-LEC can better reflect the safety state of actual working conditions, which plays an effectiveguiding role in actual production.

Key words: AHP-LEC method, smelting, risk assessment, accident
