Outline
In order to explore the theoretical contribution and application value of gray rhino risk in the field of work safety. The connotation and extension of gray rhino theory were integrated to carry out the multi-perspective integration and thinking paradigm breakthrough of the three lines of defense research on work safety. The analysis of the connotation of work safety of gray rhino and the construction of prevention and control system were carried out according to the three parts of concept integration path analysis, scenario evolution chain deduction and three lines of defense system construction. The results show that gray rhino risk has very similar cognitive interpretation attributes and conceptual mapping relationships with work safety hazard, hidden danger and accident. The work safety of the gray rhino is influenced by both subjective construction and objective real risk factors. The accident scenario evolution chain is composed of the scenario components of "system energy-inducing-disaster-bearing performance" and the risk evolution stages of "accumulation-fluctuation-mutation". Three lines of defense for work safety are constructed from the prevention and control domain of "cognitive domain- prevention domain- control domain" and the hierarchy structure of "protection layer- governance layer- emergency layer". It provides the gray rhino theory and the risk metaphor method guidance for the study of work safety management.
