A Systemic Control Model for Covid-19 Outbreak from a Safety Engineering Perspective

Reducing the consequences of the Covid 19 outbreak requires a systematic approach. The most effective way to prevent this disease is to cut off the virus transmission chain. In this letter, a systemic model for the management of the Covid 19 crisis is presented based on the bow-tie analysis model and the concept of Layers of Protection Analysis from the perspective of safety engineering. In this model, in order to reduce the patientchr('39')s entry into the hospitals, five layers of defense have been introduced to effectively manage the disease transmission chain. In addition to maintaining the health of citizens, the implementation of this model will improve the health of healthcare workers by reducing the burden of patient admission to hospitals.
