Study of dynamic risk management system for flammable and explosive dangerous chemicals storage area

In order to improve the ability of emergency management for storage area of dangerous chemicals, a framework of risk management technical system about the flammable and explosive dangerous chemicals was proposed. Combined with the dynamic changes of dangerous sources, risk analysis for storage area of dangerous chemicals was conducted based on the Bow-Tie model. Dynamic hazards analysis method and classification system were established based on Set Pair Analysis, updating results in real time with the storage capacity and accident characteristics. Integrating with the GIS, Internet of Things, detection and sensing information technology, a dynamic security monitoring system was proposed. Based on the database technology, the emergency decision support system of dangerous chemicals was made, including storage date, emergency resource, emergency plans, information of risk, etc. Using the dynamic risk management system, it can effectively achieve the goal of dynamic supervision, risk identification, real-time monitoring as well as assisting the emergency decision making of dangerous chemicals in the whole life cycle. All models are comprehensively composed of the framework of dynamic risk management system, including identification, classification, assessment, supervision and emergency management.
