Summer is coming!🌞
In preparation for the Summer when cool air from the air-cond would be needed, be sure to follow the COVID-19 preventive guidelines! 🤙
Ventilation
Common Principle 1
The risk of infection may increase if the indoor air stays for a long time as the AC is in use. So, ventilate often to let in fresh air from outside.
When air conditioner (AC) is on, indoor air is recirculated and droplets can spread to further distance. Use AC with caution for ventilation and air flow.
Air Flow
Common Principle 2
Avoid the air conditioned air from being directed straight to people. Keep the wind at low speed.
At Indoor Public Facility
- Close the window and use air conditioning, but ventilate more than once every 2 hours.
- When ventilating, natural ventilation is preferred. Open multiple windows for cross ventilation.
- In the case of mechanical ventilation rather than natural ventilation, set the amount of inflow from the outside air to the maximum.
- In the case that mechanical ventilation is set as default, apply natural ventilation in parallel whenever possible.
- Caution when using an electric fan while AC is running. It may cause internal air recirculation.
- Air conditioner filters should be properly maintained according to the equipment manual.
- When cleaning or replacing the air conditioner filter, use basic protective measures such as masks and gloves. Follow personal hygiene practices, such as washing hands.
When using AC in a closed facility where ventilation is not possible:-
- Reinforce that all visitors wear masks.
- Disinfect frequently (at least once a day).
- Control entry and exit with precaution. Prevent people who developed symptoms from accessing the place.
In an epicenter with a large number of COVID-19 patients, facilities without ventilation options should avoid using air conditioner.
To prevent the spread of COVID-19, please follow the safety guidelines in this Summer!
