Proposal for a #CitizenScience project:

• Take a mobile CO2 meter with you in various locations
• Post your measurements on Twitter
• Add the hashtag #covidco2

It would be interesting to reach people who, for example, work in a meat processing company (or other typical SSE locations) to participate. Then we finally could find out whether those cooled rooms (or those fitness centers, or classrooms,...) contain too much exhaled air.

#CovidCO2
In a cinema with room for 94, but only 5 spectators. It was ventilated with 100% fresh outside air. CO2 concentration never exceeded 600 ppm. (...which I noticed afterwards on the graph because the film was way too beautiful to keep an eye on that meter)

#CovidCO2 News on Belgian TV: ventilation of classroom was tested with CO2 measurements. Opening windows for 15 min. now and then? Not enough at all! Indoor air expert @GeertBellens rightly recommends continuous opening of windows or continuous ventilation.hln.be/video/test-kla…

New guidelines for schools in Belgium include:
• Classroom doors and windows must be wide open.
• Equip classrooms with CO2 meters. Schools will receive support and information regarding the purchase of a CO2 meter.
