Inadequate Ventilation and High CO2 Levels

Inadequate ventilation can lead to the build-up of small amounts of contaminants which are difficult to identify and test, so carbon dioxide (CO2) levels are used as an indicator of adequate ventilation in a room. Carbon dioxide is released by combustion of fuels and every time we breathe. It is normally measured at 300-350 ppm (parts per million) in the atmosphere. The legal exposure limit is a

CO2 In a Classroom – Indoor Air Quality

In Austria, building legislations state that CO2 amounts in a classroom should definitely not exceed 1,400 ppm. Normal outdoor CO2 concentration is in the range of 250-400 ppm; between 400 and 1000 ppm can be found in enclosed spaces that have good air exchange (ppm means “parts per million” and measures the mass of a chemical). Upwards of 1000ppm, causes drowsiness, and beyond 2000 ppm ...
