Use the Chart below for reference on CO2 levels and the exposure effects.
|CO2 Levels||Exposure Effects|
|250 to 350 ppm||Background (normal) outdoor air level.|
|350 to 1,000 ppm||Typical level found in occupied spaces with good aire exchange.|
|1,000 to 2,000 ppm||Level associated with compliants of drwsiness and poor air.|
|2,000 to 5,000 ppm||Level associated with headaches, sleepiness, and stagnant, stale, stuffy air. Poor Concentration, loss of attention, increased heart rate and slight nausea may also be present.|
|> 5,000 ppm||Exposure may lead to serious oxygen deprivation resulting in permenant brain damage, coma and even death|
