Abstract

In the event of the destruction or explosion of tanks with oil products, basic schemes for the distribution of pollutants have been developed in the area of a technical stop of a train at a distance of up to 1000 meters in all directions, taking into account all structures located in the study area. On the basis of an analytical assessment of the consequences of an emergency, it was shown that in the event of the destruction or explosion of railway tanks with oil products, from 90 to 95 % of economic and public facilities will be located in the zone of exceeding the MPC by 2-300 times. The limits for exceeding the permissible concentrations of polluting components in the parking area and flushing of tanks intended for the transit of oil and oil products have been established. The greatest excess will be at a distance of 300 meters from the tank car parking, where, for all priority polluting components, it is possible to exceed the MPC by 300 times. For a distance from the source of emissions more than 1000 meters in each direction of light, the calculation of the maximum permissible concentration of polluting components was performed.
