В статье рассматривается глобальная интегрированная информационная система ИМО (Global Integrated Shipping Information System - GISIS) как инструмент для формирования суточных распределений навигационных аварий. Показана недостаточность и ограниченность подобной информации, представленной в источниках, и необходимость в ее наличии для проведения исследований, касающихся предотвращения навигационных аварий и человеческого фактора. Обоснована методика формирования суточного распределения навигационных аварий с использованием GISIS. Выявлено и решена проблема «нулевого часа», связанная с отсутствием указания в отчетах о расследовании аварий времени, когда она произошла. На основе информации, содержащейся в GISIS, сделаны выборки по каждому виду инициирующих событий (навигационных аварий) по каждому часу суток за 10 лет и составлены суточные распределения аварий, которые дали возможность принять гипотезу о детерминированности столкновений, посадок на мель, навалов и опрокидываний судна временем суток с пиком на первые два часа. Сформулирован ряд содержательных выводов о причинах вида полученных распределений. The article discusses the Global Integrated Shipping Information System (GISIS) as a tool for the formation of daily distributions of navigation accidents. The insufficiency and limitation of such information presented in the sources is shown, and the need for its availability for conducting research related to the prevention of navigational accidents and the human factor. The method of forming the daily distribution of navigation accidents using GISIS has been substantiated. Identified and resolved the "zero hour" problem related to the absence of an indication in the accident investigation reports of the time when it occurred. Based on the information contained in the GISIS, samples were made for each type of initiating events (navigation accidents) for each hour of the day for 10 years and daily distributions of accidents were compiled, which made it possible to accept the hypothesis of the determinism of collisions, groundings, contacts and capsizes of the ship by time with a peak for the first two hours. A number of meaningful conclusions about the reasons for the form of the obtained distributions are formulated.

Abstract Intellectualization is regarded as the future mainstream development trend of the automobile industry. The automation level of intelligent vehicles is relatively low so far, and the road traffic system will be in a mixed state of non-autonomous vehicles and vehicles with different levels of automation for a long time. Therefore, the road traffic system will be more complex with more diverse accidents. This paper analysed the characteristics and causal factors of intelligent vehicle accidents. Based on the problems existing in investigation, analysis and liability identification of intelligent vehicle accident, the study proposed a preliminary accident investigation framework and method, summarized the key points of accident analysis from the perspectives of technical defects, information security and passive safety, and specified the liability subjects for intelligent vehicle accidents and their corresponding legal liability. The results from this study contributed to the development of intelligent vehicle accident investigation and disposal, and provided the reference for the improvement of vehicle safety and accident prevention.

Abstract This article focuses on failure analyses of aircraft components from a metallurgical and materials engineering standpoint, which considers the interdependence of processing, structure, properties, and performance of materials. It discusses methodologies for conducting aircraft investigations and inspections and emphasizes cases where metallurgical or materials contributions were causal to an accident event. The article highlights how the failure of a component or system can affect the associated systems and the overall aircraft. The case studies in this article provide examples of aircraft component and system-level failures that resulted from various factors, including operational stresses, environmental effects, improper maintenance/inspection/repair, construction and installation issues, manufacturing issues, and inadequate design.

Abstract By utilising data from official sources, a statistical analysis was made on the elevator accidents that occurred in China during the period 2002 to 2019 on five aspects namely elevator type, occurrence stage, casualty’s identity, accident type and accident causes. The main purpose is to use the frequency and correlation among related factors to evaluate crucial causes, and to prevent similar accidents among technicians and users. Based on the statistical results and discussion, some proposals were put forward to the management of the responsible authorities for accident investigation and prevention of similar elevator accidents in the future.

Abstract. Situational awareness is a concept increasingly used in aircraft accident investigation reports. We analyzed 94 general aviation accidents in which situational awareness was mentioned by the National Transportation Safety Board investigator to determine factors that are significantly more often associated with fatality. We found a consistent use of the situational awareness concept, mainly applied to situations in which aircraft inadvertently collided with each other, with other man-made objects, and with various kinds of terrain. A significantly higher proportion of fatal accidents occurred during nighttime, in instrument meteorological conditions, or low visibility conditions. In addition, flights occurring during the cruise phase or in combination with spatial or geographical disorientation proved most often fatal.

Documenting lab activity promotes safety, provides data useful in safety analysis and planning and creates a paper trail that can be used as evidence of compliance with local, state and federal regulations. Whether in academia or industry, the chemical laboratory must operate in compliance with a large number of regulations. Laboratory records play a large part in incident and accident investigation. Records and documents should be created with very specific goals in mind. They should be designed to meet these goals, preferably by those who ultimately will use them and be “standardized,” as much as possible. They should be subject to change control and retained for a prescribed period of time under conditions that will maintain their integrity. Having approved, written standard operating procedures (SOPs) in place for routine laboratory unit operations provides lab management with another way to leverage safety at the bench level.

Governments should create IT accident investigation boards for the exact same reasons they have done so for ships, railroads, planes, and in many cases, automobiles. Denmark got its Railroad Accident Investigation Board because too many people were maimed and killed by steam trains. The UK's Air Accidents Investigation Branch was created for pretty much the same reasons, but, specifically, because when the airlines investigated themselves, nobody was any the wiser. Does that sound slightly familiar in any way?

Introduction: Today, accident investigation and analysis is an important component of safety programs in preventive measures. Incident investigation involves collecting all the information and actual interpretations of an incident, analyzing information to find out the causes of the incident, and writing an incident report. Methods: This descriptive-analytical article was conducted to determine the most important criteria for investigating and selecting the techniques of accident investigation as well as analyzing and selecting the best method of accident analysis in the events of the power plant industry. In this research, previous research studies were studied and expert opinions were collected with regard to the most important criteria for choosing a specific accident analysis method. Later, the 4 accident analysis methods was applied in a special power plant accident and the decision matrix was designed based on the strengths and weaknesses of the model formation. Finally, these four methods were prioritized using the Topsis decision-making method. Results: The key factors in investigating the main criteria for selecting an incident analysis method included the ability to understand the sequence of events in the model, identifying the root causes, descriptiveness and ability to provide reasons for managers and specialists, the need for technical experts, and the time criterion. The TRIPOD BETA method was selected as the best method for analyzing the power accidents. Conclusion: The TRIPOD BETA method was introduced as the most effective method for investigating power plant accidents.
