Procedure for assessment of oil pollution propagation by soil cover, taking into account its characteristics and possibility of pollution type establishment, for prediction of emergency situation development at oil and gas complex facilities

Elfimov N.V.
FSBEE HE Siberian Fire and Rescue Academy EMERCOM of Rossia

The article presents a methodology for estimating the distribution of oil pollution on the soil cover taking into account its characteristics and the possibility of establishing the type of pollution using the drip-luminescent method. The application of this method makes it possible to quickly determine the presence and quantity of oil and petroleum products in the soil at the emergency site, which is one of the decisive factors for making decisions on the elimination of consequences. Also, to solve the issue of identifying contaminants introduced into the soil, it is proposed to use mathematical processing of the obtained volumetric spectra of luminescence. As a comparison criterion, it is proposed to use the calculation criterion (TA), which will allow calculating both when summing up the obtained values ​ ​ by registration and excitation.

An assessment of the actual individual risk of emergencies and fires for the subjects of the Russian Federation for 2019 was carried out. The results obtained are compared with the permissible individual risk of emergencies for the subjects of the Russian Federation. The regions of the Russian Federation for which the assessment of the actual individual risk of emergency situations, taking into account fires in 2019, was less than the permissible level were identified (Kamchatka Krai, Sakhalin Region, Chukotka Autonomous Okrug, the Republic of Dagestan, the Republic of North Ossetia (Alania) and the Chechen Republic). For two regions (Voronezh and Kursk regions), in 2019, the actual individual risk of emergencies, taking into account fires, exceeded the unacceptable level. For other subjects of the Russian Federation, it was less than the unacceptable level, but above the acceptable level.

The article deals with the issues of ensuring the safety of passenger transportation in the Russian subways. The article describes and analyzes the results of field experiments on large-scale models of metro rolling stock in the event of a fire in a tunnel. The process of fire propagation in the car interior and on the rolling stock investigated. The analysis and generalization of the results of field tests of the spread of fire hazards along the escape routes in the tunnel at the source of the fire in the driver’s cab and undercar equipment carried out. Based on the results of the study, the main conclusions on the spread of fire hazards formulated.

The safety issue of lithium-ion batteries, such as fires and explosions, is a major concern for their large-scale applications. Given the ever-increasing energy density of the battery, the possibility of ignition of lithium-ion batteries increases significantly. Thanks to сombustion fast burning and easy re-ignition characteristics, efficient and fast fire extinguishing of lithium-ion batteries is crucial to minimize fire hazards. Unlike conventional fires, a lithium-ion battery fire shows complicated and complex characteristics, and requires an effective and suitable extinguishing agent specifically designed for lithium-ion batteries. A fire extinguishing agent, for extinguishing the fire of lithium-ion batteries, is necessary with a high heat capacity and low electrical conductivity.

The version of arson is one of the most frequently worked out when determining the cause of the fire. The task of establishing the fact of arson can become the number one task for interrogators and fire criminologists. The main qualifying feature of arson is the fact that when examining the place of fire, traces of the use of combustion initiators are detected. This article provides methods for identifying combustion initiators using various methods.

Considered important processes of occurrence of “reverse traction”, “jogging flame” and “total flare” that occur during a fire. These phenomena accompanied by outbreaks, cottons, explosions and promote further development of a fire burning and the formation of new lesions. The process of an explosion when a small amount of water enters during extinguishing is also considered.

The article presents the results of a metallographic study of copper conductor reflow zones obtained as a result of imitation of current overloads when laying directly on the wall surface and in PVC cable ducts of different sizes. It was found that when the conductors are laid directly on the wall surface in the reflow zones, structures are formed, including copper grains with a dendritic structure. When laying conductors in cable channels in the melting zone, equiaxed copper grains and a significant number of macropores are predominantly formed. The change in the structure of the metal in the zone of reflow of the conductor when laying in cable channels is associated with a change in the conditions of heat and gas exchange.

Development of predictive behavior of digital equipment used in the oil and gas industry

Korolev D.S., Ph.D. of Engineering Sciences
Voronezh state technical university (high school)

The main task of the Russian Federation is to diversify the economy (refusal to sell hydrocarbons or reduce their share in the formation of the country’s budget). However, it is not possible to quickly implement this approach. Some experts predict that this process could take decades. Therefore, at the last investment forum, a decision was made on the digital transformation of the oil and gas industry, taking into account the introduction of new approaches in ensuring fire safety. The author of the article proposes to use an exponential distribution law. This will allow assessing all possible risks of system failure, foresee predictive behavior of digital equipment, and ensure the timely development of compensating measures.
