Accident Causation Theory

An accident is defined as an accident resulting in injury, death, loss, or damage to property or property and an undesirable situation (safety.ILO, 2011). The accident happened more deeply, led to the wrong place beyond the old cliche, bad luck, fate, omnipotent work, or at the wrong time. But in today's scientific world, there is no fate or divine work, a series of social problems caused by unfavorable events. Preventing accidents without knowing accidents is a very difficult task and research in the field of accident phenomena is quite diverse, but there has always been a fundamental problem, the cause of the accident.

In many respects, Reason's "Swiss cheese" accident causal relationship model revolutionized the general view of accident causes. Unfortunately, that is just a theory and there is little detail on how to apply it in a real environment. In other words, in this theory, at least in the context of everyday work, we do not define what "hole of cheese" is. Ultimately, we need to know what these system failures or "holes" are in order to identify them during incident investigation or to better detect and correct them before they occur .

The Swiss cheese model is a powerful model to study the causal relationship of whole body accidents. This article will help you to understand and critically compare the two models. The first part of the study is the introduction of the two models. In Part 2, we will analyze how to analyze the causes of accidents using the Sunrise nuclear power plant accident as a model. In this part, we introduce the fact of the accident first, then introduce usual accident theory and Swiss cheese model.

The initial view of the accident cause is the concept of a single event. The focus of this concept is that accidents are caused by a single event. This simple model illustrates the pursuit of the "cause" of the event. You can solve the problem by finding scapegoat and caring for scapegoat. This concept is most widely recognized and not the most complicated. Common people and media often use this concept when asking "causes of accidents". In the concept of single events, incidents can not be treated as a series of processes or events. Because "real" reasons are obvious and visible, it fails to identify or pursue factors that could lead to accidents. It is rare that the reason for emphasizing human behavior is rarely determined
