CO2 In the Classroom |

In addition to indoor pollutants, studies also found that carbon dioxide levels rose in sealed classrooms throughout the day. While humans can learn to adapt to high levels of CO2 over long periods (for example, in a submarine) over short periods, even moderate increases in CO2 will result in children who are tired, have headaches or cannot concentrate.

Carbon Dioxide (CO2) Safety Program

Carbon dioxide (CO2) is a “sleeper hazard;” very little information outside scientific literature has been published to help facilities understand CO2 health effects and control CO2 exposures. This Carbon Dioxide Safety Program is designed to fill this gap. Breathing concentrations of 30% CO2, even with 70% oxygen, leads to unconsciousness in 30 seconds Your facility may have been doing ...

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 ...

Carbon dioxide -based control is an excellent means to control ventilation automatically based on the need in premises where the number of occupants varies. The carbon dioxide -based control identifies when people enter the premises and enhances the efficiency of ventilation almost steplessly. This way, ventilation is not too efficient when there are only a few people present in the classroom ...

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
