Fire Risk Assessment Method of Transportation of Liquefied Petroleum Gases Along a Section of Track Passing Next to a Passenger Railway Platform

Действующая в настоящее время Методика определения расчетных величин пожарного риска на производственных объектах не содержит методов оценки величины пожарного риска при транспортировке пожароопасных грузов. При этом значительное количество инцидентов при их транспортировке, сопровождающихся, в частности, пожарами, показывает необходимость учета угрозы жизни и здоровью людей, как перемещающихся по путям сообщения, так и находящихся в непосредственной близости от них. В настоящей работе предложен метод оценки величины индивидуального и социального пожарного риска для лиц, находящихся в поездах пригородного сообщения и на платформах во время транспортировки сжиженных углеводородных газов. The current methodology for determining the calculated values of fire risk at industrial facilities does not contain methods for assessing the fire risk value during the transportation of flammable cargoes. The high number of transport incidents involving flammable cargoes, including fires, also highlights the need to take into account threats to life and health both of people travelling along the routes and those in their immediate vicinity. This paper proposes a method for assessing the value of individual and social fire risk for persons on commuter trains and on platforms during transportation of liquefied petroleum gases. As an example, there is considered a rectilinear double-track section of a railway track, along which transit transportation of LPG tanks is carried out. A commuter train and platform is located on the railway section. There are considered the cases of people being on the platform and in a local train. There is taken into consideration the time required to evacuate people from the wagon when calculating the fire risk. It was found that the greatest contribution to the value of potential fire risk is provided by the scenarios of a flash fire, as well as a fireball. Based on the conducted approbation of the fire risk assessment method, it can be concluded that the results obtained through the proposed methodology qualitatively coincide with those obtained in other publications. At the same time, calculations carried out using this method make it possible to calculate the fire risk value for railway passengers.
