Abstract: 
In recent years, there has been a growing interest in smart data-driven safety management systems comparing to the traditional ones. The demand for such upgrade comes from the frequent changes in our daily life and technological innovation which introduce new causes and factors of accidents. However, the increasing amount and heterogeneity of safety-related data introduces a new demand for their proper knowledge management to use them for detecting safety-related problems and predicting them. In this paper, we discuss the ontological foundations of hazards and risks which are represented by such data. We consider their representation in safety systems, specifically in the domain of aviation safety using the STAMP model. As a result, we propose a STAMP hazard risk ontology that could help in analyzing accidents and modeling control loop failures according to the theory of STAMP. For evaluation, we tested our ontology on realistic examples in the aviation safety domain as a use-case.
