This study aims to improve the reliability of emergency safety barriers by using the subjective safety analysis based on evidential reasoning theory in order to develop on a framework for optimizing the reliability of emergency safety barriers.

The emergency event tree analysis is combined with an interval type-2 fuzzy-set and analytic hierarchy process (AHP) method. In order to the quantitative data is not available, this study based on interval type2 fuzzy set theory, trapezoidal fuzzy numbers describe the expert's imprecise uncertainty about the fuzzy failure probability of emergency safety barriers related to the liquefied petroleum gas storage prevent. Fuzzy fault tree analysis and fuzzy ordered weighted average aggregation are used to address uncertainties in emergency safety barrier reliability assessment. In addition, a critical analysis and some corrective actions are suggested to identify weak points in emergency safety barriers. Therefore, a framework decisions are proposed to optimize and improve safety barrier reliability. Decision-making in this framework uses evidential reasoning theory to identify corrective actions that can optimize reliability based on subjective safety analysis.

A real case study of a liquefied petroleum gas storage in Algeria is presented to demonstrate the effectiveness of the proposed methodology. The results show that the proposed methodology provides the possibility to evaluate the values of the fuzzy failure probability of emergency safety barriers. In addition, the fuzzy failure probabilities using the fuzzy type-2 AHP method are the most reliable and accurate. As a result, the improved fault tree analysis can estimate uncertain expert opinion weights, identify and evaluate failure probability values for critical basic event. Therefore, suggestions for corrective measures to reduce the failure probability of the fire-fighting system are provided. The obtained results show that of the ten proposed corrective actions, the corrective action “use of periodic maintenance tests” prioritizes reliability, optimization and improvement of safety procedures.

This study helps to determine the safest and most reliable corrective measures to improve the reliability of safety barriers. In addition, it also helps to protect people inside and outside the company from all kinds of major industrial accidents. Among the limitations of this study is that the cost of corrective actions is not taken into account.

Our contribution is to propose an integrated approach that uses interval type-2 fuzzy sets and AHP method and emergency event tree analysis to handle uncertainty in the failure probability assessment of emergency safety barriers. In addition, the integration of fault tree analysis and fuzzy ordered averaging aggregation helps to improve the reliability of the fire-fighting system and optimize the corrective actions that can improve the safety practices in liquefied petroleum gas storage tanks.

This paper aims to explore how big data analytics (BDA) emerging technologies crossed with social media (SM). Twitter can be used to improve decision-making before and during maritime accidents. We propose a conceptual early warning system called community alert and communications system (ComACom) to prevent future accidents.

Based on secondary data, the authors developed a narrative case study of the MV Wakashio maritime disaster. The authors adopted a post-constructionist approach through the use of media richness and synchronicity theory, highlighting wider community voices drawn from social media (SM), particularly Twitter. The authors applied BDA techniques to a dataset of real-time tweets to evaluate the unfolding operational response to the maritime emergency.

The authors reconstituted a narrative of four escalating sub-events and illustrated how critical decisions taken in an organisational and institutional vacuum led to catastrophic consequences. We highlighted the specific roles of three main stakeholders (the ship's organisation, official institutions and the wider community). Our study shows that SM enhanced with BDA, embedded within our ComACom model, can better achieve collective sense-making of emergency accidents.

This study is limited to Twitter data and one case. Our conceptual model needs to be operationalised.

ComACom will improve decision-making to minimise human errors in maritime accidents.

Emergency response will be improved by including the voices of the wider community.

ComACom conceptualises an early warning system using emerging BDA/AI technologies to improve safety in maritime transportation.

The purpose of this paper is to present observations on the National Human Rights Commission report on the emergency medical services (EMS) with special reference to Uttaranchal, India.

The paper presents observations of road accidents in Uttaranchal between 2002 and 2003.

Some of the major causes of medical emergencies are road accidents, fall, burns, poisoning, drowning, suicides and attempted suicides and violence of various types. Along with this, natural disasters are a major medical emergency care. According to an estimate there is one accident in every two minutes in India. For every trauma related death, there are many injured and disabled persons. The male age group of 15‐40 years is the most affected by trauma. The cost of trauma is terms of direct costs and loss in terms of productive life is astronomical. The sudden increase in the length, breadth and kinds of roads and an exponential growth in the number and quality of transports and commuters is going to need an extremely well co‐ordinated response system. This by the very complexity of the task involved will have to be a multidisciplinary agency under a unified command. As Uttaranchal enters the fifth year of its existence the various components which would tend to aggravate the existing situation are only too apparent. Connectivity of habitats through road construction, already a top priority activity, is going to be intensified further. Exponential growth in several services sector, all leading to tremendous pressure on the existing roads and infrastructure, resulting in accidents.

The paper presents a road map for the establishment of EMS.

The purpose of this paper is to describe research, the objective of which was the development of models, methodologies, and tools for the realization of the multimedia platform for emergency management in technological systems.

This objective was achieved through the operationalization of the following major tasks: the theoretical research on the specific characteristics of emergency management system structure and processes; definition of educational structures, processes, and subjects for emergency management; development of models and software tools for the analysis of emergency development; development of information (web) services to support the collaborative decision making.

A model of multimedia platform for emergency management in technological systems has been developed, which defines emergency services with appropriate information infrastructure, the structure and characteristics of the interoperability system and their mutual communication.

Further research should result in: the concrete structure and processes of virtual organisation for emergency management in technological systems; software for the support of collaborative decision making; models for emergency management education and training based on multimedia technologies. The limitations are primarily related to model implementation, since there are no suitable emergency databases.

The platform can be used by: industrial companies, companies that provide building maintenance, public services, insurance companies, educational institutions, local authorities (by an adequate upgrade of models and software).

This paper presents the information flow identified in emergency management and the structure of a multimedia platform which, by creating favourable environment for collaborative decision making, enables effective and efficient emergency management in technological systems, as well as emergency management education and training.

Doctors and nurses in three accident & emergency (A&E) departments were interviewed about the feasibility of screening for hazardous drinking as well as the provision of minimal or brief interventions. They were also asked about a more comprehensive approach to alcohol‐related problems that would involve liaising with other services. The feasibility of a comprehensive approach to excessive alcohol consumption is considered. Quantitative data revealed that computerised A&E records did not accurately portray the prevalence of alcohol‐related attendance.

Malaysia plans to be a fully developed and industrialized country by year 2020. Malaysia has achieved good progress in the industrial sector. The industrial sector is operating plants and factories using and storing hazardous substances in quantities exceeding the threshold quantities. The plants that are dealing with hazardous substances exceeding the threshold quantity are classified as major hazard installations (MHIs). Some MHIs are located in heavily populated areas. Experience shows that MHIs pose a risk to the workers and the neighbors of the plants. Malaysia has taken the preventive measures to protect the workers and the public. The preventive measures have been taken through establishment of authorities to set major hazard control regulations, enforcing the regulations, assessing the safety reports and emergency plans, conducting audits and accident investigations. This paper reviews, in brief, the international regulations and guidelines of major hazard control. The paper also reviews the Malaysian experience of major hazard control.

Ambulance personnel face a diversity of stressful events that could be potentially traumatic, putting their health and well-being at risk. The purpose of this paper is to explore, from this group perspective, sources of stress, coping strategies and support measures.

The authors interviewed 14 ambulance workers of Portuguese Red Cross local structures from the north of Portugal. Data were analyzed according to thematic analysis procedures.

The authors identified three themes: operational and organizational factors, control and predictability; anticipating scenarios, focusing on procedures and dealing with reactions; and from undervalued support to support as routine. Dealing with human lives, the unpredictability of calls and working under pressure are the main sources of stress, causing, in some of them, insomnia, fatigue, anxiety and intrusive thoughts. Road accidents, situations involving children and cardiac arrest are the most distressing events. During events, they cope focusing on technical procedures, but after them they prefer to talk with colleagues and seek support from family and friends. All participants emphasize the inexistence of structured support measures.

It is important to develop support measures tailored to ambulance personnel’s needs, leading to enhancements of theirs work performance, health and well-being.

Contrarily to most of the studies that explore mostly PTSD and/or burnout, the authors explored, from the perspective of professionals, other dimensions such as sources of stress, coping strategies and support measures, adopting a qualitative approach, which has been rarely used.

With increasing complexity of construction projects and new construction processes and methods are adopted, more safety hazards are emerging at construction sites, requiring the application of the modern risk management methods. As an emerging technology, digital twin has already made valuable contributions to safety risk management in many fields. Therefore, exploring the application of digital twin technology in construction safety risk management is of great significance. The purpose of this study is to explore the current research status and application potential of digital twin technology in construction safety risk management.

This study followed a four-stage literature processing approach as outlined in the systematic literature review procedure guidelines. It then combined the quantitative analysis tools and qualitative analysis methods to organize and summarize the current research status of digital twin technology in the field of construction safety risk management, analyze the application of digital twin technology in construction safety risk management and identify future research trends.

The research findings indicate that the application of digital twin technology in the field of construction safety risk management is still in its early stages. Based on the results of the literature analysis, this paper summarizes five aspects of digital twin technology's application in construction safety risk management: real-time monitoring and early warning, safety risk prediction and assessment, accident simulation and emergency response, safety risk management decision support and safety training and education. It also proposes future research trends based on the current research challenges.

This study provides valuable references for the extended application of digital twin technology and offers a new perspective and approach for modern construction safety risk management. It contributes to the enhancement of the theoretical framework for construction safety risk management and the improvement of on-site construction safety.

Emergency services are critical for high‐quality healthcare service provision to support acute illness, trauma and disaster response. The greater availability of emergency services decreases waiting time, improves clinical outcomes and enhances local community well being. This study aims to assess United States (US) acute care hospital staff's ability to provide emergency medical services by evaluating the number of emergency departments and trauma centers.

Data were obtained from the 2003 and 2007 American Hospital Association (AHA) annual surveys, which included over 5,000 US hospitals and provided extensive information on their infrastructure and healthcare capabilities.

US acute care hospital numbers decreased by 59 or 1.1 percent from 2003 to 2007. Similarly, US emergency rooms and trauma centers declined by 125, or 3 percent. The results indicate that US hospital staff's ability to respond to traumatic injury and disasters has declined. Therefore, US hospital managers need to increase their investment in emergency department beds as well as provide state‐of‐the‐art clinical technology to improve emergency service quality. These investments, when linked to other clinical information systems and the electronic medical record, support further healthcare quality improvement.

This research uses the AHA annual surveys, which represent self‐reported data by individual hospital staff. However, the AHA expends significant resources to validate reported information and the annual survey data are widely used for hospital research.

The declining US emergency rooms and trauma centers have negative implications for patients needing emergency services. More importantly, this research has significant policy implications because it documents a decline in the US emergency healthcare service infrastructure.

This article has important information on US emergency service availability in the hospital industry.
