This paper proposes an amendment of the classification of safety events based on their controllability and contemplates the potential of an event to escalate into higher severity classes. It considers (1) whether the end-user had the opportunity to intervene into the course of an event, (2) the level …

Background: This paper presents the findings of a pilot research survey which assessed the degree of balance between safety and productivity, and its relationship with awareness and communication of human factors and safety rules in the aircraft manufacturing environment. Methods: The study was carried …

In the aviation sector, the variability in the appreciation of safety risk perception factors and responses to risk behaviours has not been sufficiently studied for engineers and technicians. Through a questionnaire survey, this study investigated differences amongst professionals and trainees across …

The objective of the study described in this paper is to define safety metrics that are based on the effectiveness of risk controls. Service providers define and implement such risk controls in order to prevent hazards developing into an accident. The background of this research is a specific need of …

Risk management is considered as the core process of an effective safety management system for identifying hazards and assessing risks. However, recent fatal hull loss accidents appear to have resulted from a combination of factors, none of which can alone cause an accident or even a serious incident. …

Current practice regarding risk assessment contemplates the severity and likelihood of risks and employs the use of matrices where these factors are classified and cross-referenced to evaluate risk levels. Depending on the adequacy and reliability of data, the likelihood is estimated with quantitative …

For five decades complex socio-technical systems have been studied in an attempt to understand and prevent the occurrence of accidents. In this paper, the authors define a concept for a System Complexity metric, comprising the total of all direct interactions between the system elements and the tools …

Safety investigations fall under the typical definition of a project since they have definite start and end dates and offer a specific end-product, meaning the safety recommendations which must be considered by the respective stakeholders as a means to improve the safety of daily operations. The scope …

Safety culture has been a topic of discussion in safety literature in the past three decades. Since its first mentioning after the Chernobyl accident much have been written about what fosters a positive safety culture within organizations. The Aviation Academy of the Amsterdam University of Applied Sciences …

This paper introduces the AVAC-SMS maturity metric and its accompanying tool which were developed in the frame of a research project with the aim to suggest new safety metrics, especially for Small-Medium Enterprises (SMEs). The metric is based on the ICAO Safety Management Manual, it was designed by …
