The subject of the research is key criminal risks in robotics. The purpose of the article is to confirm or disprove the hypothesis that key criminal risks of using robots may be identified and classified. The author dares to describe the key aspects of the application of risk-based approach in the assessment of robotic activities, identify the key risks of using robots, give a criminological classification. The methodology includes a formal logical method, systematic approach, formal legal interpretation of legal acts and academic literature, SWOT analysis. The main results of the study. The author applies the main provisions of criminal riskology when assessing encroachments involving robots. Key risks and challenges when using robots are identified. The severity of the consequences of harm caused by using robots (from minor to critical risk) is assessed and a matrix of the probability of its occurrence is provided. The author's criminological classification of robots is based on the risk-based approach and is substantiated on two grounds. The first one is the category of public danger and the second is the potential severity of the consequences of harm caused by robots. The causal complex that can lead to criminal risks in robotics is identified. The grounds of such risks are divided into those related to the mechanical subsystem of robots, digital subsystem of robots and power supply subsystem of robots. Conclusions. The risk-based approach is the most progressive and effective basis for regulating the criminal relations in robotics. The author demonstrates the existence of real risks to the peace and security of mankind, life and health of people, objects of wildlife, nonliving material objects from the use of robots. It is necessary to recognize robotics as source of increased potential criminal danger and to adopt appropriate regulation as soon as possible. The necessity and expediency of applying a risk-based approach to robotics is theoretically substantiated, and the characteristics of robots that are important in assessing the criminal potential of their exploitation are evaluated. The conclusions and recom mendations of this paper may become a basis for the implementation of the risk-based approach in legal regulation of robotics. The risk matrix presented in the article can be used to establish a framework for regulatory impact on robotics, assess the consequences of potential harm and minimize it.

Robotics and cyber-physical systems form an independent layer of social relations characterized by increased social danger. This circumstance predetermines the recognition of certain categories of robots as sources of increased danger. The pace of development of robotics and cyber-physical systems is a consequence of the exponential, almost explosive growth of interest in intelligent systems under the conditions of the 4th Industrial Revolution and the emergence of Industry 4.0., actively supported by the state’s policy of “universal digitalization”. The variety of robots, a high degree of adaptability and growing accessibility for the general population are a prerequisite for the “involvement” of robots in various areas of criminalactivity, up to the robots committing individual criminal encroachments on their own. As complex devices with technical, digital and energy components, robotics and cyber-physical systems are subject to processesthat can cause harm to various groups of social relations. The introduction of robotics and cyber-physical systems into industry, production and the military sphere is associated with significant risks of causing harm to various objects of criminal law protection. With the growth of autonomy, robotics will steadily expand the spheres where attacks are committed with their participation. In this regard, it is required to develop mechanisms for criminal liability in the event of harm caused by artificial intelligence and robotics systems that have a high degree of autonomy in decision-making. The criteria for requesting criminal law regulation of robotics have been determined. The main reasons for the emergence of criminological risks associated with the design features of robots have been identified. Undoubtedly, the basis for criminal law is the category of social danger, which at the same time ensures the conceptual unity of criminal law norms, while simultaneously being a watershed that delimits them from other branches of law. It is extremely important to determine the boundaries of criminal law regulation, which are formed exclusively by the public danger of certain acts with the use of robotics. Thus, it should be stated that the current level of development of robotics and cyberphysical systems, as well as their involvement in the processes of the life of society, necessitate the creation of effective mechanisms of criminal law regulation.

Objective: to conduct a critical analysis of the existing definitions of artificial intelligence and develop an authors’ version of the concept acceptable for legal sciences.Methods: the methodological basis of the study is a set of scientific cognition methods, including abstract-logical method, comparison and correlation analysis.Results: the main regularities of decision-making by artificial intelligence are identified; the mechanism of its perception of objective reality is determined; the fundamental ability of machine learning to conform its behavior to socially acceptable processes is confirmed. It is assumed that there are many ways to describe artificial intelligence: by indicating the action mechanism, the basic operation principles, the range of tasks to be solved, etc. However, the most convincing and consistent is position of those researchers who tend to describe the AI phenomenon by designating its properties and characteristics. The authors state that there is no definition of “artificial intelligence” in the modern legal doctrine. As a result of a comprehensive analysis of various scientific sources in a systematic unity with own judgments, it is proposed to introduce the author’s version of the “artificial intelligence” concept into scientific circulation.Scientific novelty: the paper presents an assessment of the “artificial intelligence” concept definitions available in the scientific literature and legal framework, as well as the authors’ opinion on their relevance, comprehensiveness and topicality; there is an attempt to formulate the definition taking into account all the significant properties of artificial intelligence.Practical significance: is due to the current impossibility to apply legal norms and rules to relations involving artificial intelligence taking into account their specifics. The main provisions and conclusions of the study can be used to improve the mechanisms of legal regulation of artificial intelligence in the Russian Federation.

The results of using a nitrogen protection system for 15 years in a sour crude oil storage park equipped with Hazmat class II and III vertical storage tanks with a stationary roof without pontoons are analyzed. Under nitrogen protection conditions, the rate of localized corrosion of the inner surface of the roof of raw and commercial crude oil storage tanks is 0.013–0.015 mm/year, which is ∼100 times lower than the rate of corrosion under natural gas phase conditions inside the tank. Continuous operation of the nitrogen protection system ensures fire and explosion safety of the tanks. Interruptions in the nitrogen protection do not have any practical effect on the efficiency of through perforation of the roof until the end of the regulated service life of the tanks, but increase fire and explosion hazard due to the formation of pyrophoric corrosion deposits.

Ecological properties of perfluorohexenes are studied in the paper. C6F12 atmospheric lifetime of 17.4 days was obtained using one-dimensional photochemical model. It was shown that the substance disappears in the atmosphere due to its reactions mostly with OH radicals. Absorption spectra of C6F12 in the short-wavelength ultraviolet region of 110-200 nm and in the infrared region were calculated using the Gaussian 09 quantum mechanical calculation program. Calculations revealed that C6F12 has significant absorption in the infrared region but due to short atmospheric lifetime of this substance its global warming potential GWP is as low as 28.64. Ozone depleting potential (ODP) of perfluoroisohexenes is equal to zero due to short chain length for the chain processes of ozone destruction involving fluorine atoms. Thus, perfluoroisohexenes with their zero ODP, short atmospheric lifetime and low GWP meet all modern environmental requirements and can be considered as effective substitutes for high-GWP HFCs in fire suppression.

Ignition takes place in a mixture of chloromethane and chlorine at atmospheric pressure and room temperature 0.1 s after the irradiation of the mixture with a UV light pulse from a mercury quartz lamp. Temperature fields are presented, which demonstrate the development of the ignition process in the dark period. Calculations show that, after the initiation is stopped, the concentration of chlorine atoms decreases to a critical value within a time of the order of 0.02 s. The observed ignition can be explained by chains branching caused by the decay of the excited CCl 3 * radical that have accumulated energy upon the successive substitution of chlorine atoms for hydrogen in the chloromethane molecule.

Flame propagation in a closed tube over mixtures of chloromethane and chlorine of different compositions following ignition by continuous UV radiation is studied. It is found that the rate of combustion in all mixtures except limiting ones grows along with the propagation of the flame front up to its maximum values at nearly 1/3 the tube length and then slows. In limiting mixtures, the speed’s behavior is completely different. It is greatest near the source of UV light and gradually slows with distance from the source. The high speed in the initial section is due to the effect of UV light. The temperature of combustion is lowest in limiting mixtures, and the rate of chlorine molecule photodissociation at this temperature is comparable to and even faster than that of their thermal dissociation. The light in these mixtures thus contributes substantially to the initiation of the chemical reaction. It is concluded that when limiting mixtures are ignited by UV pulses, the speed of flame propagation falls markedly as it proceeds without the influence of radiation, and the character of changes in the speed’s behavior becomes identical to those for other mixtures.

Calculation of dibromomethane atmospheric lifetime is carried out, as well as an experimental assessment of its fire extinguishing efficiency. Calculations show that methylene bromide atmospheric lifetime is 15.8 days so it rapidly decomposes in the troposphere. The main mechanisms of the removal of CH2Br2 from the atmosphere are its reaction with hydroxyl radicals and the processes of physical removal from the atmosphere. Special experimental equipment allowing to measure fire extinguishing concentration of gaseous fire suppressant having high boiling point is described. Experimentally measured minimum extinguishing concentration of methylene bromide for n-heptane is 2.5 % vol. According to this, CH2Br2 is close to the most effective gaseous fire extinguishing agents, such as C3F7I and C2F4Br2. LOAEL value for CH2Br2 is predicted at the level of 0.3-0.4 % vol. Due to the high boiling point of methylene bromide and its relatively high toxicity, the most appropriate way to use it in fire suppression is to create fire extinguishing mixtures, in particular, with fluorinated hydrocarbons. This approach allows to diminish application of greenhouse gases in fire protection and also to solve the problem of toxicity of extinguishing substance.

One of possible ways to reduce the volume of the use of hydrofluorocarbons (HFCs) as gaseous fire suppressants is studied in the paper. Extinguishing mixtures of HFCs and some fluoroiodocarbons are investigated. It is theoretically predicted that fluoroiodohydrocarbons are effective inhibitors of conversion of fluorinated alkanes in a flame. Special experimental equipment allowing to measure fire extinguishing concentration of gaseous fire suppressant having high boiling point is described. Experiments show that fluoroiodohydrocarbons are effective means of reducing the use of gaseous fire extinguishing agents based on fluorinated alkanes, which are greenhouse gases: in the presence of insignificant addition of iodized substance the volume of fluorinated alkanes required for the extinguishing decreases several times. Creation of mixtures with the content of iodized components higher than 5 mass. is impractical because in this case the iodine-containing substance will exceed safe level of its use from the point of view of toxicity

The introduction of small amounts of oxygen inhibits the photoinduced ignition of chloromethane–chlorine mixtures. This is accompanied by an increase in the induction period and a decrease in the degree of heating of the reaction mixture. After the consumption of the entire inhibitor, the photochlorination reaction takes place again in the thermal explosion regime but with a lower degree of heating. In the dependence of the mixture temperature on the oxygen concentration, criticality is not pronounced. With an increasing concentration of oxygen, its effect on the induction period weakens.

The deterring effect of trichloromethane and tetrachloromethane on the photoinitiation of chloromethane-chlorine mixtures is experimentally studied. It is established that, in such a system, trichloromethane as a deterrent is more effective tetrachloromethane. The higher deterring ability of trichloromethane is explained by its interacting with chlorine atoms to form low-activity trichloromethyl radicals.

The causes of the formation and the conditions for self-ignition of pyrophoric deposits in the vapor zone of tanks during the storage of sour crude oil were considered. It was demonstrated that creation of an oxygen-free atmosphere inside oil storage tanks seems to be the most promising approach to prevention of self-ignition and corrosion. This approach was effected in practice by supplying oil tanks with nitrogen from a membrane gas separator.

The action of the light emission of a mercury—quartz lamp on combustible mixtures of chlorine and difluoromethane and hydrogen at atmospheric pressure increases the upper concentration limit of flame propagation and flame velocity in mixtures similar in concentration to the upper concentration limit, because, during flame propagation in these mixtures, the rates of the thermal and photochemical dissociation of chlorine molecules are comparable, and the chlorine concentration behind the flame front is minimum.

We examine the temperature regime in the ignition of mixtures of dichlormethane and chlorine subjected to the effects of a beam of mercury light. In mixtures with a dichlormethane concentration below the lowest concentration limit of ignition the reaction occurs in a nonisothermal regime, with considerable heating of the mixture. With a higher dichlormethane concentration the reaction is explosive in nature, and the mixture is ignited. We have investigated the inhibiting of the photoignition process with oxygen. We have demonstrated that for purposes of describing the photoignition process during the initial period it is possible to use the equation for the rate of the reaction, derived under the assumption of quasisteadiness in the active particles.
