CO2 Levels Chart | |
CO2 Levels | Exposure Effects |
250-350 ppm | Background (normal) outdoor air level. |
350-1,000 ppm | Typical level found in occupied spaces with good air exchange. |
1,000-2,000 ppm | Level associated with complaints of drowsiness and poor air. |
2,000-5,000 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 permanent braindamage, coma and even death. |
