A Comprehensive Review of Autonomous Driving Algorithms: Tackling Adverse Weather Conditions, Unpredictable Traffic Violations, Blind Spot Monitoring, and Emergency Maneuvers

With the rapid development of autonomous driving technology, ensuring the safety and reliability of vehicles under various complex and adverse conditions has become increasingly important. Although autonomous driving algorithms perform well in regular driving scenarios, they still face significant challenges when dealing with adverse weather conditions, unpredictable traffic rule violations (such as jaywalking and aggressive lane changes), inadequate blind spot monitoring, and emergency handling. This review aims to comprehensively analyze these critical issues, systematically review current research progress and solutions, and propose further optimization suggestions. By deeply analyzing the logic of autonomous driving algorithms in these complex situations, we hope to provide strong support for enhancing the safety and reliability of autonomous driving technology. Additionally, we will comprehensively analyze the limitations of existing driving technologies and compare Advanced Driver Assistance Systems (ADASs) with Full Self-Driving (FSD) to gain a thorough understanding of the current state and future development directions of autonomous driving technology.

Human error and violation of rules in industrial safety: A systematic literature review.

Human error and violation of rules are perceived as deviations from some desired behavior, appearing variably in literature as either similar or opposing concepts. Behavioral deviations may be linked to accidents or considered a protective factor against them. This article aims to explore definitions, characteristics, classifications, and management approaches for behavioral deviations, specifically human error and violation of rules. A systematic literature review was conducted. The authors differ in defining and classifying error and violation, associating them with generation of accidents or their prevention. The management proposals for deviations highlighted by the authors were emphasized. The findings of this article reinforce the prominence of authors Jens Rasmussen and James Reason in the field. They assert that deviations are a natural aspect of the work process and even serve as a preventive factor against accidents, although their frequent association with accidents remains common in organizations. This study contributes to theoretical understanding by systematizing prevalent perspectives on deviation, human error, and violation of rules. It proposes a taxonomy and emphasizing the need for managing deviations, rather than combating them, especially in an organizational context.

Bentuk-bentuk Pelanggaran terhadap Tata Tertib Sekolah oleh Peserta Didik di SMA dan Implikasinya bagi Layanan Bimbingan dan Konseling

Statistics of protein electrostatics.

Molecular dynamics simulations of a small redox-active protein plastocyanin address two questions. (i) Do protein electrostatics equilibrate to the Gibbsian ensemble? (ii) Do the electrostatic potential and electric field inside proteins follow the Gaussian distribution? The statistics of electrostatic potential and electric field are probed by applying small charge and dipole perturbations to different sites within the protein. Nonergodic (non-Gibbsian) sampling is detectable through violations of exact statistical rules constraining the first and second statistical moments (fluctuation-dissipation relations) and the linear relation between free-energy surfaces of the collective coordinate representing the Hamiltonian electrostatic perturbation. We find weakly nonergodic statistics of the electrostatic potential (simulation time of 0.4-1.0 μs) and non-Gibbsian and non-Gaussian statistics of the electric field. A small dipolar perturbation of the protein results in structural instabilities of the protein-water interface and multi-modal distributions of the Hamiltonian energy gap. The variance of the electrostatic potential passes through a crossover at the glass transition temperature Ttr ≃ 170 K. The dipolar susceptibility, reflecting the variance of the electric field inside the protein, strongly increases, with lowering temperature, followed by a sharp drop at Ttr. The linear relation between free-energy surfaces can be directly tested by combining absorption and emission spectra of optical dyes. It was found that the statistics of the electrostatic potential perturbation are nearly Gibbsian/Gaussian, with little deviations from the prescribed statistical rules. On the contrary, the (nonergodic) statistics of dipolar perturbations are strongly non-Gibbsian/non-Gaussian due to structural instabilities of the protein hydration shell.

“I probably feel slightly more invincible”: The impact of technology that discloses enforcement locations on drivers’ behaviours

There is a plethora of technology currently available that have the ability to notify individuals of traffic enforcement locations while they are driving. This technology has the potential to undermine legal deterrent efforts for preventing risky driving behaviours. However, drivers’ experiences using this technology and the trajectories through which this might interfere with deterrence for road rule violations are largely unexplored areas. As such, the present study aimed to explore two research questions: 1) what type of technology is used and how is it used, and 2) how does drivers’ use of this technology influence deterrence for road rule violations. In total, 58 Queensland licenced drivers who use technology that informs them of legal enforcement while driving participated in focus groups. To consider differences in use between ages, the sessions were conducted in three different age groups: 17–25 years, 26–49 years, and 50+ years. Reflexive thematic analysis was applied to the data, resulting in eight recognised themes. The findings highlighted that for most drivers, the primary purpose of using the technology was for navigation, while being notified of enforcement locations was a secondary purpose. In addition, the use of this technology encouraged road rule compliance for some yet was used as a strategy to avoid being caught for road rule violations for others. The findings have a number of practical and theoretical implications, demonstrating the complex interplay between technology used for enforcement notifications, its role in deterring road rule violations, and the principles of responsible innovation.

Oligonucleotide therapeutics in sports? An antidoping perspective.

Within the last two decades, the European Medicines Agency and the US Food and Drug Administration have approved several gene therapies. One category is oligonucleotide therapeutics, which allow for the regulation of the expression of target genes. Besides already approved therapeutics, there are several preclinical and clinical trials ongoing. The World Anti-Doping Agency prohibits the use of "nucleic acids or nucleic acid analogs that may alter genome sequences and/or alter gene expression by any mechanism" as a nonspecified method at all times. Hence, the administration of nucleic acids or analogs by athletes would cause an Anti-Doping Rule Violation. Herein, we discuss types of oligonucleotide therapeutics, their potential to be misused in sports, and considerations to sample preparation and mass spectrometric approaches with regard to antidoping analysis.

Inclusive intervention design for vulnerable road users: Applying co-design and behaviour change model in Bangladesh

In developing countries, it is debatable whether poor design of facilities or violation of traffic rules by road users is the leading cause of pedestrian injuries and deaths. Professionals, pedestrians and drivers tend to blame each other. Shared responsibility for road safety is crucial for protecting vulnerable road users such as commuting students and workers who face higher injury risks while crossing highways. While the Safe System approach emphasises authorities’ responsibility for safe facilities, understanding user needs and promoting behaviour change remain underexplored. This study investigates the current design practices in Bangladesh. It compares the impact of conventional design with co-design on intervention quality and examines the further benefits of integrating a behaviour change model ‘COM-B’.Local road agency professionals applied the design process and suggested interventions at four highway sites. Subsequently, four focus group sessions were conducted with students and workers, followed by four design workshops. In each workshop, participants were randomly assigned to two design groups (without and with the application of the behaviour change model), where they designed interventions facilitated by professionals. Lastly, perception ratings of stakeholders and safety assessments by four experts were conducted to evaluate the efficacy of all interventions.The findings highlight major usability problems in conventional designs, while co-designed interventions demonstrate clear improvements. Notably, integrating a behaviour change model further enhances effectiveness. Stakeholder interviews reveal that co-design fosters shared responsibility and addresses the blame culture. The co-design approach and application of the behaviour change model can address design flaws and promote the proper use of facilities.

Investigating the driving skills-attitudes nexus for safer roads

While current research extensively delves into the importance of driving skills and attitudes concerning traffic safety, a conspicuous gap remains in substantiating a meaningful correlation between self-reported driving skills and attitudes toward traffic safety. This underscores the need for more in-depth investigation and empirical evidence to better elucidate the nature of the relationship between self-perceived driving skills and attitudes in the context of traffic safety. This study investigates the relationship between drivers' skills and their attitudes toward traffic safety. Data from 664 drivers were collected through self-report questionnaires covering driving skills, attitudes, and demographic information. Factor analysis revealed three distinct factors for both driving skills (perceptual-motor skills, safety skills, and decisional skills) and driving attitudes (attitudes toward rule violations and speeding, attitudes toward careless driving of others, and attitudes toward drinking and driving). Structural equation models unveiled a significant connection between drivers' attitudes and safety skills, as well as decisional skills. Improved safety skills correlated with less favorable attitudes toward rule violations, speeding, careless driving of others, and drinking and driving. Similarly, enhanced decisional skills were associated with a rise in attitudes toward rule violations, speeding, and disregarding careless driving of others. Demographic analysis indicated an inverse correlation between age and attitude factors/decisional skills, coupled with a positive correlation with safety skills. Older individuals had less favorable attitudes toward rule violation, speeding, careless driving of others, the combination of drinking and driving, and their decisional skills were lower. Gender analysis revealed that men had a lower favorable viewpoint toward all three attitude dimensions and reported higher perceptual-motor and decisional skills compared to safety skills. The findings underscore the significance of safety and decisional skills in shaping attitudes toward traffic safety. Demographic factors, particularly age and gender, play a role in influencing these skills and attitudes, offering valuable insights for interventions and policy considerations.

An improved variant of quantitative randomized response techniques using forced responses

The randomized response technique has gained a wide popularity among survey researchers over the past few decades. Randomized response procedure is applicable in a variety of fields including sociology, psychology, business, and education, etc. It is a useful method which helps the researcher in dealing with the high non-response rates in sample surveys on sensitive issues such as monthly income, traffic rules violations, income tax amount, and expenditure on luxury items, etc. We introduce an optimal scrambling technique which uses forced responses. The algebraic properties of the estimator of population mean using the suggested technique have been derived. For the purpose of comparison with existing models, the different measures of model-evaluation have been obtained. Our analysis suggests that the new quantitative technique using forced responses is better than the available scrambling techniques not only in efficiency, but also in the combined metric of model’s efficiency and level of privacy, which make it more useful than the available models for practical problems. Using real-world example, we illustrate its practical implementation to sensitive sample surveys.

Analysis of fiscal sustainability and its impact on enhancing economic growth in Iraq for the period (2004-2021)

The research aims to analyze and measure the reality of the Iraqi economy for the period (2004-2021)by applying the concept of financial sustainability and its indicators on economic growth. The paper's problem lies in the weak implementation of financial sustainability and indicators in most financial decisions in Iraq, negatively impacting economic growth in most economic sectors in Iraq. The paper started from the hypothesis that the weak implementation of financial sustainability in most of Iraq has contributed to the weakness of economic growth. The validity of the hypothesis has been proven using a standard model known as the Multiple Regression Model (ARDL), the study has yielded several results, the most important being the inverse relationship between the budget deficit as an independent variable and economic growth as a dependent variable. The budget deficit reached (59%) of the "gross domestic Product" indicating a deviation from the 3% deficit defined by the Maastricht treaty to ensure deficit coverage. Iraq's deviation from this percentage will lead to a decrease in economic growth. The paper also revealed an inverse relationship between public debt as an independent variable and economic growth as a dependent variable due to Iraq's violation of the golden rule, which dictates allocating debt to the investment side rather than consumptive spending. Paper type: Research paper.

Socioeconomic and behavioral factors of road traffic accidents among drivers in Ethiopia: systematic review and meta analysis

BackgroundRoad traffic accidents (RTAs) are a pressing public health issue in Ethiopia, exacerbated by rapid urbanization and motorization. Despite efforts, escalating rates persist due to various factors like human behavior and road infrastructure deficiencies. This study addresses the need for comprehensive data on RTAs in Ethiopia, aiming to uncover socioeconomic and behavioral factors to inform evidence-based policies.MethodsA systematic review and meta-analysis were conducted from March to April 2024, adhering to PRISMA guidelines. Major databases like Google Scholar, PubMed, and the Cochrane Library were searched using specific keywords related to RTAs and Ethiopia. Studies conducted between 2014 and 2024 were included, with eligibility criteria. Data extraction followed a standardized Microsoft Excel format. Study quality was assessed using the JBI checklist, with high-quality articles included. Statistical analysis, conducted using STATA version 17, included descriptive analysis, forest plots for RTA prevalence, and examination of publication bias using Egger and Begs tests. Subgroup analysis and meta-regression explored moderating factors and sources of heterogeneity.ResultsThe systematic review identified eight studies meeting inclusion criteria, conducted between 2014 and 2022. RTA prevalence was 36% (95% CI: 23; 49). Sensitivity analysis confirmed the robustness of the estimated prevalence. Publication bias was detected via Egger’s test, though Begg’s test was non-significant. Meta-regression found no significant influence of publication year or sample size on RTA prevalence. Socioeconomic factors like income level and driving experience, alongside behavioral factors like traffic rule violations and substance use, were identified as key drivers of RTAs in Ethiopia.ConclusionsThe study highlights the significant burden of road traffic accidents in Ethiopia, influenced by socioeconomic and behavioral factors. Socioeconomic factors such as income level and driving experience, along with behavioral factors like traffic rule violations and substance use, emerged as prominent determinants of RTAs. Policymakers should prioritize evidence-based interventions targeting these factors to improve road safety nationwide.

Emerging New Media Syntax, Violation of English Syntactic Rules, and Meaning Misrepresentations

A new variety of English syntax emerged with the new media. This study examines new media syntax to show instances of mindless violation of grammatical rules and the misrepresentation of meanings among student users of the new media. The study relies on selected social media posts. Descriptive survey, textual and content analyses, and interpretive techniques are employed. The analysis demonstrates that new media syntax, a corrupted or bastardized form of the English syntax, is characterized by syntactic deviations, grammatical violations, misrepresentation of meanings, and informal features, which affect the performance of students in English Language courses or subjects because most of them transfer the syntactic features of new media syntax to their formal compositions. The study concludes that the strained use of new media exerts adverse effects on English syntax and students’ writing and performance because they lose marks to the transferred features of new media syntax to the formal English syntax, which causes solecism, violation of grammatical rules and misrepresentation of meanings. Teachers are charged to consistently teach students how to use new media language for its associated informal contexts and purposes alone rather than mixing it with the formal variety in formal compositions.

Influence of pseudo-Jahn-Teller activity on the singlet-triplet gap of azaphenalenes.

We analyze the possibility of symmetry-lowering induced by pseudo-Jahn-Teller interactions in six previously studied azaphenalenes that are known to have their first excited singlet state (S1) lower in energy than the triplet state (T1). The primary aim of this study is to explore whether Hund's rule violation is observed in these molecules when their structures are distorted from C2v or D3h point group symmetries by vibronic coupling. Along two interatomic distances connecting these point groups to their subgroups Cs or C3h, we relaxed the other internal degrees of freedom and calculated two-dimensional potential energy subsurfaces. The many-body perturbation theory (MP2) suggests that the high-symmetry structures are the energy minima for all six systems. However, single-point energy calculations using the coupled-cluster method (CCSD(T)) indicate symmetry lowering in four cases. The singlet-triplet energy gap plotted on the potential energy surface also shows variations when deviating from high-symmetry structures. A full geometry optimization at the CCSD(T) level with the cc-pVTZ basis set reveals that the D3h structure of cyclazine (1AP) is a saddle point, connecting two equivalent minima of C3h symmetry undergoing rapid automerization. The combined effects of symmetry lowering and high-level corrections result in a nearly zero singlet-triplet gap for the C3h structure of cyclazine. Azaphenalenes containing nitrogen atoms at electron-deficient sites - 2AP, 3AP, and 4AP - exhibit more pronounced in-plane structural distortion; the effect is captured by the long-range exchange-interaction corrected DFT method, ωB97XD. Excited state calculations of these systems indicate that in their low-symmetry energy minima, T1 is indeed lower in energy than S1, upholding the validity of Hund's rule. Jahn-Teller analysis predicts the symmetries of the in-plane distortion vibrational modes as or B2: C2v → Cs agreeing with the vibrational frequencies of the saddle-points.

Features of the use of unmanned aircraft during the inspection of the scene of the incident during the investigation of violations of the road safety rules or vehicle operation

The article highlights the procedural and tactical features of the inspection of the scene of a traffic accident with the use of an unmanned aerial vehicle. To achieve this goal, the forensic features of conducting an inspection of the scene during the pretrial investigation of crimes of violations of road safety rules or vehicle operation at each of the preparatory, working, and final stages are revealed. The current state and prospects of the use of unmanned aerial vehicles by the bodies and units of the National Police during the inspection of the scene of a traffic accident were studied. The advantages of using an unmanned aerial vehicle during the inspection of the scene of a traffic accident are given, the concept of an unmanned aerial vehicle is defined, the methods and tactical methods of using an unmanned aerial vehicle. Scientific and practical recommendations are given on the procedure for recording crimes with the help of an unmanned aerial vehicle regarding violations of the rules of road traffic safety or vehicle operation during the inspection of the scene of the incident. It was concluded that the use of an unmanned aerial vehicle in the activity of the investigator during the investigation of traffic accidents is legitimate and provides much more advantages than the use of other methods of recording, such as measuring with a manual or laser tape measure, taking photos or video recording with cameras or video cameras. The use of UAVs during the inspection of the scene of the incident significantly reduces the time of its inspection, while providing the opportunity to obtain high-quality and sufficient evidentiary material.

Peculiarities of the criminalization of smuggling of goods and its importance for filling the state budget

Smuggling of goods is a complex and multifaceted phenomenon that has a significant impact on the economic and social situation in the country. The illegal movement of goods across the border not only undermines economic stability, but also poses a threat to national security, contributing to the development of the shadow economy and corruption. In the conditions of globalization and the growing integration of international markets, the issue of combating smuggling becomes especially urgent, because this phenomenon is becoming more and more large-scale and difficult for state control. Criminalization of the smuggling of goods is a key mechanism for countering this negative phenomenon, which involves the establishment of stricter liability for violations of customs rules. It should be noted that the effectiveness of the criminalization of customs offenses depends on a number of factors, including the presence of effective legislation capable of adequately responding to new challenges, the effectiveness of law enforcement agencies, as well as the level of international cooperation in this area, etc. However, given the specifics of the Ukrainian economy and the country’s geopolitical location, the smuggling of goods remains a serious problem that requires a deeper analysis and an effective solution. One of the key aspects of the fight against the smuggling of goods, which became one of the main reasons for its criminalization, is its impact on filling the state budget. Illegal trade in goods deprives the state of significant financial revenues that could be directed to the development of social programs, infrastructure projects and ensuring economic growth. The loss of these resources weakens the country’s economic potential, undermines trust in state institutions, and contributes to growing social tensions. The article examines the impact of smuggling on the state’s economy, emphasizing the negative consequences for filling the state budget. Examples of significant economic losses incurred by the state due to smuggling are considered, as well as the role of customs authorities in combating this phenomenon is highlighted. A set of measures is proposed to reduce the level of smuggling, including changes to legislation, increasing the effectiveness of customs control and strengthening international cooperation.

Different subregions of monkey lateral prefrontal cortex respond to abstract sequences and their components.

Sequential information permeates daily activities, such as when watching for the correct series of buildings to determine when to get off the bus or train. These sequences include periodicity (the spacing of the buildings), the identity of the stimuli (the kind of house), and higher-order more abstract rules that may not depend on the exact stimulus (e.g. house, house, house, business). Previously, we found that the posterior fundus of area 46 in the monkey lateral prefrontal cortex (LPFC) responds to rule changes in such abstract visual sequences. However, it is unknown if this region responds to other components of the sequence, i.e., image periodicity and identity, in isolation. Further, it is unknown if this region dissociates from other, more ventral LPFC subregions that have been associated with sequences and their components. To address these questions, we used awake functional magnetic resonance imaging in three male macaque monkeys during two no-report visual tasks. One task contained abstract visual sequences, and the other contained no visual sequences but maintained the same image periodicity and identities. We found the fundus of area 46 responded only to abstract sequence rule violations. In contrast, the ventral bank of area 46 responded to changes in image periodicity and identity, but not changes in the abstract sequence. These results suggest a functional specialization within anatomical substructures of LPFC to signal different kinds of stimulus regularities. This specialization may provide key scaffolding to identify abstract patterns and construct complex models of the world for daily living.Significance Statement Daily tasks, such as a bus commute, require tracking or monitoring your place (same, same, same, different building) until your stop. Sequence components such as rule, periodicity (timing), and item identity are involved in this process. While prior work located responses to sequence rule changes to area 46 of monkey lateral prefrontal cortex (LPFC) using awake monkey fMRI, less was known about other components. We found that LPFC subregions differentiated between sequence components. Area 46 posterior fundus responded to abstract visual sequence rule changes, but not to changes in image periodicity or identity. The converse was true for the more ventral, adjacent shoulder region. These results suggest that interactions between adjacent LPFC subregions provide key scaffolding for complex daily behaviors.

Governance and policy implications of the Inflation Reduction Act: A European perspective

AbstractThis paper examines the US 2022 Inflation Reduction Act (IRA) alongside the EU's Net‐Zero Industry Act (NZIA) and Critical Raw Materials Act (CRMA) of 2023. We analyze their differential approaches to accelerating investment in clean technology, enhancing energy security and fortifying supply chains. Both regions share the objective of diminishing reliance on Chinese dominance in clean industries. The US seeks to stimulate private investment primarily via uncapped tax credits from 2022 to 2031, some of them subject to stringent domestic content requirements. The EU has reacted to the potential violation of World Trade Organization's rules and a possible green investment shift to the US In doing so, the EU is relying heavily on a regulatory strategy, with emphasis on the simplification of procedures. However, the EU's public funding model is vague and leaves details to the discretion of member states, risking fragmentation within the single market. Through the application of a dynamic computable general equilibrium model, we show that a 50% increase in demand for the IRA's uncapped tax credits could nearly triple US GDP outcomes by 2027. We highlight the contrast between the IRA's immediate fiscal incentives and the NZIA's regulatory approach, emphasising that the former are more attractive for firms.

Polysomatic intergrowths between amphiboles and non-classical pyriboles in magnetite: Smallest-scale features recording a protracted geological history

Abstract Non-classical pyriboles (NCPs) have tetrahedral silicate chains (Ibeam) of multiplicity higher than single (pyroxene) or double (amphibole) Ibeams and are known from amphiboles in altered mafic-ultramafic complexes. NCPs, their polysomatic sequences, and inherent chain-width disorder are petrogenetic tools for interpreting igneous and metamorphic processes. Magnetite, a refractory mineral that can trap and preserve NCPs is a major constituent of iron oxide-copper-gold (IOCG) deposits. We undertook a nanoscale study to show that NCPs and amphiboles are hosted within magnetite cores from the Jatobá Ni-bearing IOCG deposit, Carajás Mineral Province, Brazil. Monoclinic amphiboles and NCPs form polysomatic intergrowths or occur as sparse inclusions along {111}magnetite. There are two chemical populations of amphiboles: Mg-Fe- and Ca-(Al)-amphiboles, the latter including Ce-bearing Mg-hornblende and (ferro)tschermakite. The occurrence contains one of the widest ranges of chain silicates ever recorded, from simple intergrowths of single to triple Ibeam zippers, including pyroxene slabs, to longer NCP polysomes up to 15-Ibeam chains. Clinojimthompsonite (Cjim) is observed for the first time within magnetite. Although no discrete polysomes could be defined, the NCP-amphibole intergrowths have compositions between Mg-Fe amphiboles and Cjim based on Ibeam averages of 2.5–2.7. Relationships between increase in the number of C and A cations from amphibole (2-Ibeam) to n chain silicates (nIbeam) are formulated as nIbeam = T(2 + n) = C(5 + 3n) = A(1 + n), n = integer. Empirical models of crystal structures, validated by STEM simulation, are shown for 4- and 5-Ibeam chain silicates. Co-crystallization of double- and triple-chain silicate structures with rhythmic intergrowths as larger blocks along b is often accompanied by rhythmic Ca-Fe zonation along a, supporting primary NCP crystallization via self-patterning during amphibole growth within magnetite in a close-to-equilibrium system. Chain-width disorder is documented from defects including planar faults, derailments, jogs, and swells. Violations of zipper termination rules indicate primary growth rather than replacement. Amphibole-NCPs inclusions support a multi-stage evolution for Jatobá magnetite. They formed during the first cycle of magnetite overprinting within a mafic/ultramafic lithology that records syn-shearing events. Subsequent formation of calcicamphiboles, including Ce-bearing species, indicate IOCG-related fluids at the onset of mineralization. (Ferro) tschermakite formed at ~7.5 kbar during high-pressure shearing is preserved during main ore deposition. The multi-stage amphibole-NCPs generations in magnetite revealed by our nanoscale study emphasize the interpretive value of magnetite for overprinting events in terranes with protracted geological histories. Analogous NCPs are likely to be abundant in magnetite from magmatic-hydrothermal deposits hosted by greenstone belts and altered mafic/ultramafic complexes. Likewise, discovery of Ce-rich hornblende provides new avenues to understand the early, alkali-calcic alteration stages of IOCG systems and models for REE incorporation into, and subsequent release from chain silicates.

Applied and expert research on fire and industrial safety of main pipelines

The article provides an analytical assessment of the consequences of violations of industrial and fire safety rules during repair work on the example of main oil pipelines. The issue is urgent due to explosions and fires, as well as staff injuries, which requires an analysis and assessment of the causes of their occurrence and reliability improvement during repair work at hazardous production facilities in Irkutsk region. The factual basis of the study is data on incidents related to the personnel training and repair sites, explosions (pops), the dynamics of the emergency situation and consequences for personnel and the economy. The study concludes that in terms of eliminating explosions and fires and minimizing their consequences, the industrial and fire safety system has not been properly developed for repair and other works at hazardous production facilities.
