Risk Assessment of Air Versus Other Transportation Modes for Explosives and Flammable Cryogenic Liquids. Volume I: Risk Assessment Method and Results

摘要

This report describes a method for assessing the comparative risks of transporting hazardous materials by alternative routes and modes. The method is then applied to the transport of Class A explosives and liquid hydrogen between specific origin-destinations, testing the air-highway modal combination with alternative combinations of highway, rail, and marine modes. The risks were found to be highly route-dependent; however, for those routes selected, the air-highway modal combination showed generally lower risks. Rerouting and improvement in terminal operations showed the greatest opportunity for risk reduction.
