| The safety of road transport of dangerous chemicals is one of the key issues in China.Despite many policies issued by the state,the company has implemented a number of management and control measures to strengthen the management of road transport of hazardous chemicals,but road transport accidents of hazardous chemicals are still frequent.occur.This is due to the fact that under the traditional safety management model,hazardous chemicals road transport systems lack the ability to actively respond to unforeseen emergencies,and the concept of resilience has been introduced into the security discipline to improve this deficiency.The resilience is the ability of the system itself to cope with change.At the present stage,the research on road traffic resilience is mostly from the perspective of the government on the resilience of the road transport system,and the resilience of the road transport system.There is no uniform and effective method for the assessment.Therefore,from the perspective of the company’s safety management of road transport of hazardous chemicals,this article discusses how to improve the resilience of hazardous chemicals road transport systems.This paper first quantifies and improves the traditional FRAM method.Then,taking a transportation company in Sichuan as an example,the improved FRAM method was studied and analyzed for the resilience of its dangerous chemicals road transport management process.Through the study,we identified nine major functions of the transport system: receiving transport tasks,checking dangerous chemicals,checking transport vehicles,packaging dangerous chemicals,loading dangerous chemicals,transporting dangerous chemicals,Monitoring the transport of dangerous chemicals,Unloading dangerous chemicals and Cleaning inspection trucks.Subsequent analysis of changes in time and accuracy for each function,identifying functional outputs as too early,on time,too late,missing,accurate,acceptable,and inaccurate.When the changes and changes are coupled to the system function,it is identified that the system has insufficient restoring force and resilience during operation.Next,scores and frequency assignments for changes in system functionality were performed using Monte Carlo simulations using @Risk software to identify four key functions that may occur during system operation: Packaging Hazardous Chemicals,Loading Hazardous Chemicals Products,Transportation of Hazardous Chemicals and Unloading Hazardous Chemicals,where the function Transport of Hazardous Chemicals may have the highest possibility of functional resonance.Finally,based on the analysis results,we analyze the changes and changes in the coupling of these functions,and propose corresponding barriers and regulatory recommendations.We propose improvements to the road transport management system for hazardous chemicals to enhance the system’s resilience. |
