This paper reports on the results of a security analysis of the European Railway Traffic Management System (ERTMS) specifications. ERTMS is designed to be fail-safe and the general philosophy of ‘if in doubt, stop the train’ makes it difficult to engineer a train accident. However, it is possible to exploit the fail-safe behaviour of ERTMS and create a situation that causes a train to halt. Thu...

Monitored and diagnosed the machinery equipment by the fault diagnosis technology can find machine malfunctions in time and prevent the equipment’s worst accident from occurring, so that it can avoid casualties, environmental pollution and enormous economic losses. Applied the fault diagnosis technology can find the potential causes in the process of producing equipment, so that eliminate poten...

Traffic accidents are one of the leading causes of fatalities in the US. An important indicator of survival rates after an accident is the time between the accident and when emergency medical personnel are dispatched to the scene. Eliminating the time between when an accident occurs and when first responders are dispatched to the scene decreases mortality rates by 6%. One approach to eliminatin...

Deployment of the air bag in a passenger vehicle accident rarely causes otologic injuries. However, sensorineural hearing loss induced by air bag deployment is extremely rare, with only a few cases reported in the English literature. A 38-year-old man involved in a traffic accident while driving his car at 40 km/hour presented with right sensorineural hearing loss and tinnitus, without associat...

The purpose of this study was: (1) to propose a classification system for the contributory factors behind major coach and bus accidents with mass casualties based on human factor analysis (HFACS); (2) identify main indicators causal factors. Based 56 official investigation reports more than 10 fatalities, qualitative content was conducted develop modified these accidents, gray correlation causa...

A study of past accidents in the chemical process industry (CPI) has been carried out. It is found that the majority (73%) of the accidents were caused by technical and engineering failures. Based on the causes of accident and types of equipment failures, five common features of accident in the CPI were identified. The analysis reveals that the contribution of the design to accidents is signifi...

In this paper, the actions less known but contributed to mitigate outcome of Fukushima accident in the light of the concept of resilience engineering are described with the emphasis on the human positive contributions. Although accident reports already published mainly focuses on finding persons to be blamed and on finding root causes, there were judgments and actions that reduced the disaster ...

This paper describes the results of an independent analysis of the primary and contributory causes of aviation accidents in Canada between 1996 and 2003. The purpose of the study was to assess the comparative frequency of a range of causal factors in the reporting of these adverse events. Our results suggest that the majority of these high consequence accidents were attributed to human error. A...

Background: The effectiveness of safety systems is critical to the realization of their goals. Thereششfore, this study was conducted to investigate the role of safety management systems on accidents and the status of safety performance indicators in a combined cycle power plant in 2011. Materials and Methods: This descriptive-analytical research was carried out in two stages in all Yazd Combin...
