In our article, we develop the concept of safety capital, which on the individual level includes internalized safety knowledge, behavior, and attitudes. The concept is useful both in terms of academic safety research and applied research. We strive to create a foundation for a multidisciplinary understanding of safety that is both focused on the individual and community levels. Increasing safety capital is an effective goal that is important for both structural and individual level safety. First, we open key concepts, such as safety and different forms of capital, then define the concept of safety capital, including attitudes, competence (knowledge and skills), feeling of safety, and trust. Finally, we consider how safety capital is developed and maintained. We present safety capital as its own form of capital, with elements of both cultural and social capital, which can be distinguished both as a resource of the individual, and more broadly, in society.
