Study On Risk Management Of Hazardous Chemicals Road Transportation

As a big country in industrial production, China’s hazardous chemicals have grown rapidly in product and circulation. Hazardous chemical because of its chemical properties, it often involves flammable, explosive and corrosive properties, so it’s likely to cause serious accidents in production, loading, transportation and other aspects. According to statistics, hazardous chemicals accidents occurrence in transport links accounted for 35 percent Hazardous chemicals accidents. Hazardous materials transportation safety issue has become an issue of concern. Implementing risk management on its road transport is an effective way to reduce the risk of transportation.Based on the principles of systems engineering, the risk factors in hazardous chemicals road transport system has been analyzed from human, material and environment, and the risk coupling mechanism is analyzed. Common risk assessment models on transportation of hazardous materials are introduced. It establishes a evaluation index system, carrying out risk assessment to these three risk by the fuzzy comprehensive evaluation method. It establishes a three-dimensional risk assessment model, the comprehensive risk of road transport dangerous goods during road transportation will be evaluated. Based on the acceptable risk criteria, establish a HME risk decision model. Based on the risk classification and risk treatment choice logical tree diagram, select the appropriate risk treatment scheme. Then expounds the importance of emergency management and construct a dangerous chemicals road transport emergency rescue system. Finally, combined with the conerete example, the risk of a company’s dangerous goods transportation of a route is evaluated, the risk treatment scheme and risk control measures are put forward, and a road transport risk management system is established.
