Abstract

In order to give a more scientific definition of safety, combining the basic hypothesis of bounded rationality of human beings in economics, the whole emergence feature of the system science, and the objectivism and constructivism in epistemology, the attributes and characteristics of safety were thoroughly analyzed from four dimensions of basic hypothesis, system theory, epistemology and restrictive conditions. A new definition of safety was proposed: safety is a state in which a system is protected from unacceptable risks in a given context. Based on this, the connotation and extension of the new safety definition were analyzed. The results show that the essence of safety is risk acceptability, that the safety research is to find a method to determine the acceptable risk and establish acceptable risk criteria which conform to the national conditions of China, and that in the process of research, we should take the system as the research object, establish a suitable bounded rationality model, and takes into account the influence of social construction factors. © 2021 China Safety Science Journal
