The Federal Aviation Administration (FAA) has been developing the Integrated Safety Assessment Model (ISAM) to provide a baseline risk assessment for the National Airspace System and to evaluate the safety impact of proposed changes to the system. ISAM consists of a set of event sequence diagrams and underlying fault trees for various accident scenarios. In the current model, all basic events i...

In aviation, it is common to have several aircraft operating in similar conditions uneventfully, yet another aircraft, following suit, experiences an accident in the same conditions. With the same information available to crews of both aircraft, conditions can quickly change leading to an accident for one, while the other crews land safely. Should this situational ambiguity be the cause of the ...

The quest to explain and understand the cause of accidents is both ever-present ongoing amongst safety science community. In an attempt advance theory accident causation, researchers have recently formalised a set ‘15 systems thinking tenets’ that cover conditions characteristics work are believed contribute accidents. purpose this study was identify tenets across range different using Accident...

China has a large vehicle base, uneven road conditions, and the highest rate of traffic accidents in world. Particularly on long downhill sections expressway tunnels mountainous areas with harsh geographical are densely distributed, once accident occurs, consequences serious, which poses threat to people’s lives property. This paper mined analyzed data collected by project Baoding section Zhang...

Abstract From 2016-2018 there were 120 fuel station accidents in Indonesia. Fuel may harm not only workers but also the public. Major stations have caused multiple fatalities and injuries. Various research regarding has been done, on role of community preventing is limited. Therefore, studying cause effect essential. The study aims to collect accident information determine impact, cause, possib...

The pipeline spanning is triggered by the unevenness of seabed. cyclic fatigue loadings from subsequent scouring make be prone to failure which can cause loss integrity and even catastrophic accident. However, probabilistic modeling a free subsea challenging task due its dynamic characteristics uncertain information. This paper proposes methodology that could capture uncertainty time dependence...

Traffic accidents occurring are one of the most important issues that cause loss life and property people. With increasing population, number vehicles in use creates traffic density. For this reason, studies aimed at reducing vital importance. In study, a total 3833 fatal injured occurred between 2010-2017 Şişli district were analyzed with help geographical information systems Kernel density me...

Many things can cause traffic accident, including the driver behaviour. Aggressive drivingbehaviour is associated with risk of accident. driving behaviour usuallypredicted by external factors, such as other driver’s attitude or gesture that could trigger anger.However, aggressive also be shown in a situation where there no otherdriver, for example when someone drive high speed an empty traffic....

Ischemic heart disease (CHD) is one of the most common diseases circulatory system, which main cause death in Ukraine. The purpose this study was to analyze incidence, disability, mortality from ischemic disease, its individual nosological forms adult population evacuated 30 km zone Chernobyl nuclear power plant post-accident period, taking into account age at date accident, sex and time after ...
