Railway Transportation of LPG: A Risk Assessment of LPG in the Course of Load-and-Unload

LPG are potentially harmful to people and environment due to their toxic ingredients, especially in the course of load-and-unload. In this work, based on the fault tree and Gaussian plume model, we develop a risk assessment model for the railway transportation of LPG in the course of load-and-unload. This model can take into consideration the features may lead to explosion accident and their impact. At the same time, when the leakage of LPG leads to explosion accident, the model can determine the longest distance in the harmful explosion and the harmful explosion area quantitatively. With application of the case, a risk assessment model for the LPG in the course of loading and unloading is presented.
