Abstract: In order to improve accuracy and timeliness of safety information cognition, to further optimize safety behaviors and promote system safety management. Firstly, safety information feedback was defined from perspectives of feedback nature and communication studies, and its connotations were studied. Secondly, a model of safety information feedback principle was established based on information processing process, namely acquisition, analysis and utilization of information. Finally, on the basis of such feedback principle, a safety information feedback failure mechanism model was constructed building on event chain principle, and possible influence factors of system failure in process were analyzed. The results show that safety information feedback is an effective way to adjust system's safety structure, safety function and safety behavior, and studies on its failure mechanism will provide new ideas for improvement of system safety.

Key words: safety information feedback, failure mechanism, safety information cognition, feedback principle, information processing
