Railway transportation safety management must adhere to the approach of safety and prevention first. The transport of dangerous goods should be paid more attention as a particularly important part. This paper made use of fault tree analysis to research and analyze the risk factors of dangerous goods LPG which may explode in the rail transport. The analysis was made from two aspects of chemistry and physics, then the minimal cut sets and structure importance of the specific factors which may cause explosion accidents are solved, and the importance of each factor is analyzed and sorted on the calculated results. Based on the above method, measures of LPG rail transport explosion prevention were proposed.

Dangerous goods - goods which, by the nature of their physical characteristics, chemical composition, dimensions, or other specific features and nature (live animals or fish), for some reason endanger human life or health, the environment natural or general order or material goods, including those with features of the principles of humanitarianism. The transport of dangerous and oversize goods is one of the most difficult specialties in the field of goods transport in public transport, in particular in road and rail transport. Such transport is regulated by a number of legal acts that do not apply to companies carrying out tasks related to the transport of loads, the so-called neutral. The United Nations has created a closed TN directory, giving everyone a four-digit "UN number", at the same time dividing them into classes depending on the threat or the predominant threat. The provisions of the ADR agreement relate, inter alia, to the rules (requirements) for TN transport in terms of limiting the possible effects of a potential release of hazardous substances (e.g. as a result of road or rail collisions), as well as, above all, the forms and principles of preventing the possibility of such events. The transport of dangerous goods is a special type of transport and it is subject to specific legal provisions, meeting and observing a number of specific requirements. The safety of this type of transport depends on the proper organization of its transport and the maximum involvement of participants in the entire process. The organization of the transport of hazardous materials requires a comprehensive, comprehensive view of the vehicle, packaging and cargo (means of transport and packaging should be adapted to the transported goods) as well as people involved in the preparation of transport, drivers with appropriate authorizations and training, setting the route, securing this routes in terms of maintaining safety in the event of an emergency. The article offers the author's approaches to the investigation of modern challenges of dangerous and extraordinary goods transportations.

Canada’s rail transportation network is a critical part of Canada’s integrated supply chain which connects industries, consumers, and resource sectors to ports on the Atlantic and Pacific coasts. One transportation activity that is essential to most industries, especially oil and manufacturing, is the rail transport of dangerous goods (DG). Although rail transportation of DG is beneficial to Canada’s economy, not paying attention to the safe transportation of these types of goods can have irreparable effects on the economy, human lives, and the environment. Recent rail accidents, such as Lake Wabamun in 2005 and Lac-Mégantic in 2013, have shown that there is still room to increase the safety of transportation of DG by rail through improving railways’ safety management systems (SMS). As a result, investigations to increase the safety of rail transportation of DG have been started. This work is part of these initiatives focusing on enhancing railways’ SMS, particularly DG main-track train derailments. The current study applied detailed root cause analysis (RCA), the bow tie analysis (BTA), and incident databases to identify the main causes and consequences of these types of accidents (2007–2017). Then, the relationship between these factors and gaps in SMS elements were identified and the frequency of each factor was investigated. The results showed that the main gaps are related to process and equipment integrity, incident investigation, and company standards, codes, and regulations. Furthermore, some useful recommendations are presented to improve the management of each SMS element and reduce these gaps.

To provide an objective tool for assessing the risks involved in the transport of dangerous goods, a model called RISKMOD-I was developed for Transport Canada by the Institute for Risk Research. The model implements the computational aspects of a comprehensive risk assessment methodology which addresses both the quantitative and qualitative aspects of dangerous goods releases following a transport incident. This paper describes the model's implementation, data requirements, and outputs.The risk assessment model consists of an analysis of link-specific accident rates and a fault tree analysis to determine the probability of a dangerous good release of a particular type. In parallel, a series of commodity-specified damage models compute the impact areas associated with representative sizes and types of releases. The impact areas for each damage threshold are then multiplied by the population density and property exposure along each link to determine the total risk associated with a dangerous goods shipment that uses the link. This estimate of total risk can optimally be further converted into a risk cost value in monetary terms and summarized for the entire route. Both the risk and risk cost estimates are intended to be used in conjunction with other subjective analyses and performance measures to provide a comprehensive decision-making aid for risk managers. Key words: dangerous goods transport, truck and rail accidents, risk analysis.

The authors examined the scientific basis for managing environmental and economic risks in the transport of dangerous goods by rail. The importance of optimizing the monitoring of environmental safety and the organization of environmental risk management was noted. The paper presents the interrelation of the functional strategy of ensuring the reliability of the transportation process with other strategies. A new functional strategy and a schematic diagram of the environmental management system for making management decisions to optimize environmental management in railway transport have been proposed. A conceptual apparatus has been developed to identify and determine environmental risks and the principle of their management during the transport of dangerous goods by railway transport.

Fire and explosion accidents occur frequently in tankers because they transport large quantities of dangerous cargo. To prevent fire and explosion accidents, it is necessary to analyze factors that cause accidents and their effects. In this study, factors that cause fire and explosion accidents were classified using the 4M disaster analysis method, and each factor’s effect on the accident was analyzed using fault tree analysis (FTA). First, the unsafe tank atmosphere environment was identified as a primary cause of fire and explosion accidents in tankers, and the underlying causes of these accidents were investigated. The probability of underlying causes leading to primary causes was derived using an expert survey. The results showed that management and media factors had a greater impact on the unsafe tank atmosphere environment than human factors. To prevent fire and explosion accidents, it is necessary to ensure sufficient working and resting times for seafarers and compliance with procedures and work guidelines. A generalization of the results of present and future studies will enable the identification of the cause and preventive measures for fire and explosion accidents in tankers. Furthermore, this will reduce accidents in tankers and contribute to future safety management measures of ships and companies.

A shipboard fire/explosion may be occurred due to various causal factors such as actions, omissions, events or conditions. In this study, it is aimed to carry out an analysis focused on shipboard fire/explosion casualties. With this aim, the data on 127 shipboard fire/explosion casualties occurred in the Turkish Search and Rescue area, which were reported to the Main Search and Rescue Coordination Center between 2006-2015, have been analyzed. As a result of the statistical analysis (descriptive statistics), it has been observed that majority of the shipboard fire/explosion casualties were occurred on-board the Turkish flagged ships, on-board small passenger vessels/recreational vessels/private-commercial yachts among the classified ship types, in the regions of İstanbul, İzmir and Çanakkale, in the summer season, during the night-time, and in machinery spaces of the ships by described locations. It has been also observed that main events caused shipboard fires/explosion casualties were electricity contact/leakage, gas accumulation/leakage, cargo ignition, welding/hot works and other undescribed factors. Additionally, by examining the existing shipboard fire & explosion accident investigation reports of Transportation Safety Investigation Center between 2014-2020, it has been observed that the main possible causal/contributing factors for the shipboard fire/explosion casualties were related with the violations of the ISM-Safety Management System (SMS) requirements. Many previous studies in the relevant literature point out to the ISM/SMS-related causal/contributing factors as well. In conclusion, special attention should be paid to the effective implementation and continuous improvement of the ISM/SMS procedures related with shipboard fire safety for the prevention of shipboard fire/explosion casualties as well.

The amount of dangerous goods (DG) transported by rail within Canada has increased by an average of approximately 25% since 2004, with a 42.5% increase in transported fuels and chemicals between 2011 and 2017. Further, movement of DG by rail is forecasted to continue increasing. Sustainable growth in the transport of dangerous goods (TDG) by rail will require acceptable safety levels. This study provides insight into key occurrence types for TDG and their causes, to better focus on risk control strategies, including measurement and control of leading and lagging safety indicators. This work also reviews current safety performance and Canadian railway incident occurrence databases. The results of the analyses suggested that the performance against lagging indicators currently being reported is adequate, including derailments and collisions (main and nonmain track), serious injuries (including fatalities), DG leakers, and releases. Furthermore, a list of the rail accidents with the greatest number of fatalities was used to calculate a crude estimate of societal risk associated with rail transportation. According to UK Health and Safety Executive (HSE) recommendations, this analysis indicated that the estimated rail transport risks would be considered acceptable when assessed at a milepost scale. However, there are opportunities for further enhancing safety reporting, management, and performance.

Every day, products identified as dangerous goods are transported across the EU by road, rail, water and air. Currently, large quantities of different types of dangerous goods are transported by rail. The influence of random factors and events can lead to an accident resulting in a leakage of hazardous substances. These types of incidents not only threaten the safety of rail transport, but also life, environment and property. The paper defines legal framework of DGT (dangerous good transport), risks during the carriage of hazardous materials and the main advantages of the rail transport of dangerous goods, compared with other transport modes.
