Minot Recommendations to FRA:: Minot Recommendations to FRA: Validate a predictive model that will quantify the dynamic forces acting on a tank car during an accident Develop and implement tank car design-specific fracture toughness standards for materials used to manufacture pressure tank carsChlorine Gas Releases:: Chlorine Gas Releases: 12 Fatalities Graniteville, South Carolina (9) Macdona, Texas (3) Large lethal clouds are generated within minutes Little time to alert citizens Reduction of Public Risk:: Reduction of Public Risk: Operational changes are needed to reduce the vulnerability of tank cars transporting poisonous by inhalation gases.Transportation Studies:: Transportation Studies: The rear one-quarter of a train is the most desirable location for Haz Mat Reducing speed Reducing the length of trains You do not have the permission to view this presentation.
