The aim of the article is to show the transformations in the implementation of safety content in secondary schools. The problem situation was considered in the cognitive category, hence the theoretical research methods such as analysis, synthesis, inference and abstraction were used. The curriculum of this subject currently implemented with the program introduced in the school year 1989/90 was analyzed. The research results show that over the decades, strictly defensive education has gradually given way to education in favor of broadly understood security, resulting in the broadening of the cognitive perspective. This dependence allowed us to conclude that in the praxeological design of safety education processes, it determines the organization, forms and conditions of the classes. Thus, the content on designing the process of education for safety, contained in 1989, also appears today. Despite the passage of time, they still seem to be up-to-date and needed.
