The correct way to open 2020!
The end of the long Spring Festival holiday is approaching day by day, and people will embark on their return to work like a tide. Nowadays, during the epidemic period of the new coronavirus pneumonia, how should office workers protect themselves in the daily office environment? How should the office environment reduce cross-contamination? OU University brings the three magic weapons of "Ventilation-Disinfection-Self-Protection" to give you some advice.

Ventilation is one of the most effective ways to prevent respiratory infectious diseases. Natural ventilation is preferred. Places with windows that can be opened, including relatively closed spaces such as offices, canteens, and conference rooms, should open doors and windows as much as possible to maintain good indoor ventilation. Intermittent ventilation is possible, but the cumulative ventilation time per day is not less than 2 hours; if natural ventilation is poor, forced ventilation means (such as split air conditioners, exhaust fans, etc.) can be used to exchange indoor and outdoor air.
Open windows to ventilate and breathe fresh air
Disinfection—Reduce cross-contamination
After returning to work after the Spring Festival holiday, it is particularly important to disinfect office facilities. Computer keyboards and mice are regularly disinfected with 75% alcohol.
