ABSTRACT
Communities have had to make concerns when and how schools serving students in schools and campus should re-open against temporary closure to slow the spread of COVID-19 virus. Apart from continuing COVID-19 health protocols for all students, teachers and staffs, technology support needed for air circulation disinfection in crowded and inadequately ventilated space like a classroom. This study examines the impact of using UVC tools and combine with evidence-based source control practices, whether refine indoor air quality to best minimize exposure risk to COVID-19 for staff and students. This study found airborne disinfection can be solved through UVC irradiation with measured radiation 7,31 mW/cm2 since previous published research only need 5 mW/cm2 at least one second. The recommendation from this study, government need to raise public policy for education institutions to apply ultraviolet germicidal irradiation (UVGI) chamber to cut-off virus airborne transmission by circulating and disinfect indoor air during in-class activities all day long.
