Methods to Classify, Forewarn and Pre-control Routine Operation in Hazardous Liquid Chemical Storage and Transportation Port

In light of the actual operation and risk characteristics of hazardous liquid chemical storage and transportation port, we identified the division of eight types of routine operations in this paper. Based on the risk assessment theory, eight risk classification index systems were established according to the SMART principle and expert questionnaire survey, with their classification standards and quantization scores being determined. The AHP method was used to compute index weights, on whose basis the operation risk classification model was built up. Targeted at different risk classifications, we provided specific forewarning signals and measures for pre- control. The proposed scientific and highly-efficient risk forewarning and pre-control systems provide a scientific theory and devisal to classify, forewarn and pre-control routine operation in hazardous liquid chemical storage and transportation port.
