Whenever possible, place the CO2 gadget at eye level and not directly next to windows or people.
- Green light (< 1’000 ppm): good indoor air quality, no need to action
- Yellow light (1’001 ppm – 1’600 ppm): intermediate indoor air quality, trigger ventilation or open windows
- Red light (> 1’600 ppm): bad indoor air quality, trigger ventilation at high level or open all accessible windows

Reduce the risk of virus infection in classrooms
Ventilate indoor spaces regularly and thoroughly - this is recommended by the Federal Environment Agency to reduce the risk of Sars CoV-2 infection. This announcement is particularly relevant in view of the fact that the school has started again at full class size. For this reason, the supply of fresh air in the classrooms should also be as high as possible, regardless of other protective measures such as keeping minimum distances or wearing a mouth-and-nose cover. After all, droplets and tiny aerosol particles should play a decisive role in the transmission of Sars-CoV-2. Especially the aerosol particles that are produced when breathing, coughing, speaking and sneezing can float in the air for hours or days, according to current knowledge. Consistent ventilation can significantly reduce the risk of infection, but cannot provide 100% protection.
