Prevention and control in advance embodies the essence of risk management, and risk early warning index system is the key link of implementing risk early warning. In order to construct risk early warning index system of typical chemical production process, the risk identification, analysis and early warning theory are closely combined in this paper, the accident risk factors are extended to three aspects, as possibility, severity and sensitivity. Based on the common accidents of typical chemical production process, the risk factors of the production process are comprehensively analysed and the risk early warning index system is put forward based on three dimensional factors. Through the index screening methods for interval estimation, the primary warning indicators are screened. Finally, the risk early warning index system of typical chemical production process is determined.
