10 tips for enjoying a safe summer

Ventilation

It is of utmost importance that building ventilation is managed in accordance with the recommendations. As the virus is spread through aerosols, ventilation plays a crucial role in reducing the infection risk. It allows for indoor air renewal of classrooms and reduces the presence of these aerosols, which may be contaminated with COVID-19 by an infected person present in the room.

The CO2 content of the air should, ideally, not exceed 900 ppm and under no circumstances should it exceed the standard of 1200 ppm. To achieve this objective, key actions must be taken. These actions are described in the document “Practical recommendations for monitoring ventilation and air quality in COVID-19” prepared by the Ventilation Task Force of the COVID-19 Commissariat.

For measuring the CO2 concentration in a room, please refer to the document “Selection and use of CO2 sensors in the framework of COVID-19," also prepared by the Ventilation Task Force of the COVID-19 Commissariat.
