(105c) Quantitative Risk Analysis Applied to Transportation of Acute Toxic Chemicals

Transportation of acute toxic chemicals is a key activity in the supply chain, which has been increasing due to market globalization. Routes might include railcar, truck, ship, crane movements, etc. and might pass through locations with high population, which may pose significant risks as an accidental release can potentially expose a large public population. This presentation will show the application of quantitative risk analysis (QRA) to determine the risk profile along the length of the route and help to identify potential high-risk locations and operations. In addition to discussing the consequence and frequency analysis methodology, refinements of the model using Failure Mode and Effects Analysis (FMEA), Finite element analysis (FEA), and other methods will also be presented. It will be demonstrated using case studies how the QRA results can be used for decision-making and developing comprehensive risk mitigation strategies.
