Ventilation is the best prevention for the spread of COVID-19!
According to World Health Organization(WHO), changing 30% of indoor air for an hour reduces the risk of infection to 1/20. When our health authorities determine whether close contacts should be quarantined, indoor ventilation and mask-wearing are considered important criteria.
University Ventilation Rules
ㅇ When people stay indoors continuously, it is a rule to always leave windows and doors open. (Lecture rooms, offices, cafeteria, library, study rooms, meeting rooms, etc.)
ㅇ Ventilate for at least 10 min. every hour. (Ventilation for 5 min every 30 min. is more effective)
ㅇ Open both windows and doors in a diagonal direction for outdoors air to push the indoors air out faster.
