Abstract

Based on the 19 selected representative chemical enterprises in jiangsu province, we investigate the safety risk situation of chemical enterprises from the aspects of personnel technical level, equipment failure, major hazard sources, production process, environment, accident, certification, safety assessment and emergency response capacity. We found the following problems: the most part of staffs education is below undergraduate course; have major hidden dangers at district/county level and above; the vast majority of enterprises of dangerous chemicals maximum action/reaction temperature over dangerous chemicals flash point, etc. The index system of chemical enterprise safety risk state is constructed from six aspects: personnel, equipment, material, method, environment and safety management. The key index system of security risk state warning is put forward from the aspects of personnel, equipment, method, environment and safety management. We use the analytic hierarchy process (AHP) method to determine the chemical enterprise safety risk status indicators weight, and finally determine the state of the chemical enterprise safety risk classification standard.
