Safety cases embody arguments that demonstrate how safety properties of a system are upheld. Such cases implicitly document the barriers that must exist between hazards and vulnerable components of a system. For safety certification, it is the analysis of these barriers that provide confidence in the safety of the system. The explicit representation of hazard barriers can provide additional ins...
Introduction: Hospital preparedness for accidents and disasters is vital in maintaining and promoting community health. However, the country's hospitals are not well prepared for disasters. The hospital safety index (HIS) was 42% in Iranian hospitals in 2014. This study aims to investigate the HSI in Iranian hospitals in 2020 and to provide solutions to improve it. Methods: This cross-sectiona...
Background and aim: hazardous materials transport is one of the most important problems in developing countries. The accidents involving the fleet of hazardous materials transport can have irreparable consequences. The study was aimed to present safety performance assessment pattern of road trucks with risk assessment approach. Methods: This is a descriptive study. In this study, the Accidents...
In response to a weight of evidence that patients are frequently harmed as a result of their care, there have been concerted efforts to make healthcare safer, with health systems across the globe investing significant resources in policies and programmes designed to reduce adverse events. Yet, despite extensive efforts, improvements in safety have proved difficult to sustain and spread, with st...
Nowadays the active traffic management is enabled for better performance due to the nature of the real-time large data in transportation system. With the advancement of large data, monitoring and improving the traffic safety transformed into necessity in the form of actively and appropriately. Per-formance efficiency and traffic safety are considered as an im-portant element in measuring the pe...
Cyber-physical systems tightly integrate physical processes and information and communication technologies. As today’s critical infrastructures, e.g., the power grid or water distribution networks, are complex cyber-physical systems, ensuring their safety and security becomes of paramount importance.Traditional safety analysis methods, such as HAZOP, are ill-suited to assess these systems. Furt...
Introduction: Today, organizations need an integrated management system (IMS) to achieve global standards regarding the environment and employees. And one of the important goals of an integrated management system is to eliminate or reduce disasters to an acceptable level of organization. Therefore, in this study, we try to measure the efficiency of deployment of this system on safety performanc...
Introduction: The weaknesses of traditional hazard analysis methods lead to their inefficiency to utilization for modern socio-technical systems. System Theoretic Process Analysis (STPA), which is in the category of systematic analysis methods, has a powerful logic to identify hazards in such systems,as a suitable alternative method. This study aimed to analyze hazards associated with extinguis...
Background and Aim: The analysis of patients’ safety clinical indicators is considered as one of the safety improvement instruments. Therefore, the present study is aimed to analyze the indices of safety clinical services in selected hospitals of Tehran University of Medical Sciences (TUMS). Materials and Methods: The present descriptive-analytical study was conducted in 11 TUMS hospitals in...
