Statistical data and equipment parameters are used to analyze accidents caused by the termination of the receipt of electricity and heat, technical failures, control failures and human errors. The main reasons for the damage of technological equipment are determined on the example of the head oil pumping station GNPS-1 “Taishet” in connection with fire propagation scenarios; the ways of solving the problems are described. Exceeding the design loads while maintaining the design strength of the equipment causes excessive mechanical effects. An example of the mechanical action is an increase in operating pressure in technological equipment. Violation of the integrity of the structural material of pipelines and technological devices occurs as a result of electrochemical corrosion. In the presence of moisture on the surface of structures, a film containing dissolved air and atmospheric impurities develops. The use of corrosion-resistant materials and the insulation of the inner and outer surfaces of pipelines with anticorrosive coatings increase their reliability. The most dangerous scenarios of accidents, fires, and explosions are accidents at three sites: in the tank farm, at the main oil pumping and back-up pumping stations. The scenarios for the development of an accident of the technological equipment and pipeline sections will allow us to determine the distribution of fire risks on the territory of the facility and beyond its borders, including assessing the magnitude of fire risks in order to develop measures to reduce it.

The goal is to determine the individual fire risk at the stages of transportation and storage of petroleum products on the example of a typical oil depot in Irkutsk region and to develop measures aimed to reduce the likelihood of leakage of petroleum products and limit the impact of fire and explosion hazards. The research objects are probabilities of adverse fire-related events (the block diagram method was used) and individual fire risks (the regulatory methods were used). Using the event tree method and taking into account the standards requirements, the probability of accident development scenarios was calculated. Consequences of fire-related emergencies were predicted. The calculated distributions of individual fire-related risks at oil products storage facilities made it possible to identify areas of maximum danger for the personnel. The dangers when unloading railway tanks, storing petroleum products in tanks RVS-2000 and filling automobile tanks were investigated. The parameters of negative events were calculated following possible emergency scenarios for the personnel. The distribution of damage probabilities caused by dangerous fire and explosion-related factors at the production site for the most probable emergency scenarios than can develop at railway tanks on a railway overpass, a group of tanks RVS-2000 and automobile tanks was studied. The fire risk value was calculated at each point of the tank farm. Measures aimed to reduce the risk to the personnel in hazardous areas were suggested.
