Critical Analysis of Train Derailments in Canada through Process Safety Techniques and Insights into Enhanced Safety Management Systems

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.

Development of Early Warning and Evacuation System for Multi-Density Facilities in Case of Fire

Multi-density facilities with relatively large number of resident occupants and visitors can face large-scale casualties in the event of disasters such as a fire. In addition, such disasters may cause additional damage by inducing social anxiety regarding various protection measures of the buildings, such as their safety management systems. This study was aimed at developing an early warning and evacuation system to minimize casualties in multi-density facilities in case of a fire. In particular, smoke and heat detectors, which are widely used, were utilized to establish an early warning system for old multi-density facilities with relatively poor safety management systems. For the purpose of evacuation following the early warning, an online platform-based ‘Fire Safety Management’ system was established to deliver appropriate action tips to all occupants according to the four risk stages of a fire.

Safety Management for Unmanned Aviation

In Air Traffic Management (ATM), Safety Management Systems (SMS) provide the principal vehicle for implementing safety policies, practices and procedures in accordance with internationally agreed Standards. In a constantly changing operating environment, it is essential to maintain SMS effectiveness to maintain and enhance levels of ATM safety. Research at the University Politehnica of Bucharest (UPB) has analysed the major, fast-rising threats to ATM safety emerging in the field of unmanned aviation. After considering the operating environment in terms of control arrangements and unmanned vehicle types, the relationship between ATM and Unmanned Traffic Management (UTM) is examined. It is concluded that the SMS supporting ATM requires enhancement to address the risks arising from the emergence of unmanned aviation and relevant enhancement measures are therefore proposed. Further, research shows that detailed safety management arrangements to support UTM are not yet defined. Indicative SMS requirements for UTM are therefore derived and presented.

BARRIERS TO THE DEVELOPMENT OF OCCUPATIONAL HEALTH AND SAFETY MANAGEMENT SYSTEMS IN THE NIGERIAN CONSTRUCTION INDUSTRY

OHSMS has become the main part of the establishment’s lifeline and a prerequisite for its stability in the 21st century. There is a growing need for OHSMS, in its ability to solve occupational accidents and also to develop a robust relationship among the stakeholders. The mission of OHSMS has not been followed in the Nigerian construction industry. The study, therefore, explores the barriers to the development of OHSMS in the Nigerian construction industry. The study adopted a literature review of OHSMS and thereafter, 300 structured questionnaires were administered to the construction professionals in the built environment of the Nigerian nation’s Capital-Abuja. 247 of the administered questionnaires were returned, considered for the analysis of the study. The data were analysed with SPSS and excel. The findings of the study indicate that the lack of commitment of the government, inefficient regulatory authorities, and lack of expertise in the OHS activities are the major barriers to the development of OHSMS. The study recommends collaborative efforts from the construction organizations, employees, and construction professionals to support the government on the OHSMS.

ISO 22000 Certification: Diffusion in Europe

The main aim of this paper is to answer the research question, “Is the Gompertz model suitable for studying the diffusion of the ISO 22000 standard in Europe?” Forecasting models adopting the Gompertz model were developed to estimate to which extent the Food Safety Management Systems (FSMS) based on the ISO 22000 standard are expected to be implemented and certified in the European continent. To provide a forecast for the next few years, data from the diffusion of renowned ISO standards, namely, ISO 9001 and ISO 14001, were extrapolated in order to overcome the shortcoming since data concerning ISO 22000 certification was only available for the period 2007 to 2018. The results provide a cross-sectional portrayal of the European diffusion of ISO 22000 certification and suggest an interval of the estimated number of certificates issued in Europe. This research paper presents the first attempt to empirically analyze the dynamic of diffusion of the European ISO 22000 certification. A more accurate fitting with real results may be expected with further information available in the forthcoming years.

Implementation of Food Safety Management Systems along with Other Management Tools (HAZOP, FMEA, Ishikawa, Pareto). The Case Study of Listeria monocytogenes and Correlation with Microbiological Criteria

The food industry’s failure in planning and designing of and in implementing a Food Safety Management System and its foundation elements leads, in most instances, to compromised food safety and subsequent foodborne illness outbreaks. This phenomenon was noticed, worldwide, for all food processors, but with a much higher incidence in the medium- and small-sized food processing plants. Our study focuses on the importance of Food Safety Management System (FSMS), Critical Control Points Hazard Analysis (HACCP) and the Prerequisite Programs (PRPs) as the foundation of HACCP, in preventing foodborne outbreaks. For emphasis, we make use of the example of organizational food safety culture failures and the lack of managerial engagement which resulted in a multi-state listeriosis outbreak in USA. Moreover, we correlate this with microbiological criteria. Implementation of food safety management systems (ISO 22000:2018) along with incorporation of management tools such as HAZOP, FMEA, Ishikawa and Pareto have proved to be proactive in the maintenance of a positive food safety culture and prevention of cross-contamination and fraud.

Involving Moral and Ethical Principles in Safety Management Systems

Some organisations, and some individual humans, violate moral and ethical rules, whether or not they are written down in laws or codes of conduct. Corporate transgressions, as this behaviour is called, occur because of the actions of those in charge, usually bright and dedicated people. Immoral and unethical conduct can adversely affect the safety of workers, the general public and the environment. A scoping review method for a literature search is used to explore morality and ethics in relation to health and safety management. Our findings show that controlling the risks associated with misconduct and corporate transgression is not usually seen as a responsibility allocated to safety systems but is left to general management and corporate governance. The moral and ethical principles, however, can be applied in safety management systems to prevent misconduct and transgression-related safety risks. Our results show that ethical leadership, ethical behaviour, sustaining an ethical climate and implementation of an ethical decision-making process emerge as key preventive measures. The discussion presents a proposed way to include these measures in safety management systems. Conclusion and recommendations underline that unwanted behaviour and transgression risks can be brought under control, starting from a set of best practices. Not only the managers themselves but also board members, independent external supervisors and government regulators need to embrace these practices.
