All emergency areas were routinely disinfected three times daily. For air disinfection, the resuscitation room and buff zone were disinfected by hypochlorous acid atomization, and the other areas were disinfected by man-machine coexistence ultraviolet-C (UV-C) disinfection panel lights. The equipment, facilities, and floor surfaces were wiped or mopped with disposable wipes or towels soaked with 1,000 mg/L chlorine disinfectant. The toilet was sprayed with chlorine disinfectant of the same concentration.
For areas where COVID-19 exposure was found, terminal disinfection was performed in the entire area. The air was disinfected using an intelligent disinfection robot that automatically walked around the clinic area spraying hydrogen peroxide at an action concentration of 8–12 g/m3. Floor disinfection was performed by spraying with 2,000 mg/L chlorine disinfectant for 30 minutes before cleaning. Other surfaces of equipment and facilities were disinfected with disposable hydrogen peroxide wipes. Following terminal disinfection, sampling was carried out to assess environmental safety. The main ED reopened after negative PCR tests were reported for all staff, visitors, and the environment.
