The 1990s and Onward

Although the Swiss cheese model is fundamentally a linear accident trajectory model that leans heavily on the concept of safety barriers, these analytic subtleties postdate its inception and evolution. And, as commented almost two decades after the first installment came out: the Swiss cheese model has an indisputable value as a means of communication, as a heuristic explanatory device. It has had a significant influence on the understanding of accidents, and therefore also on the practical approach to accident analysis and prevention. It has successfully been applied as a means of accident analysis and proactive measurements, although the level of resolution does not go as far as for other models.Reason, Hollnagel, & Pariès (2006, p. 21)

Annually, millions of occupational accidents occur in the world and cause considerable losses to countries and organizations. Understanding the causes of these accidents will lead to the implementation of better strategies to prevent their reoccurrence [1]. In other words, understanding why accidents occur and how to prevent their reoccurrence is an essential part of improving safety in any industry. Accidents that may seem to be unfortunate incidents (putting something in the wrong place at the wrong time) can be seen as the result of a chain of failures and mistakes. To improve safety, conducting investigations plays a major role in efficient safety management and is fundamental to learning from accidents [2]. Accident analysis is the core aspect of accident investigation and includes the method of connecting different causes in a procedural way. One of the most important steps in accident analysis is the conscious selection of the accident analysis method. This is because these methods are based on various models developed by the advances in the science of safety over the past century. New insights into accidents have resulted in the development of novel models and methods. The following factors or criteria are used to compare and select accident analysis methods: the method should be easy to understand and apply, guidance material should be available and clear, the method should present a graphical format for the output, the method should be valid (correspondence between the analysis findings and reality) and consistent (a reliable method should facilitate the agreement between results and different assessors), etc. [3–10].

Accident analysis is an essential tool for developing prevention policies. Recently, organizations have tried to collect reliable occupational injury data so that measures can be instituted to prevent similar occupational accidents for jobs such as cooks, moving helpers, waste collectors or hotel employees [1–6].
