OSHA does not have IAQ rules, they have workplace exposures for CO2 which is 5000ppm. Remember this is a level where harm may result.
Now many groups have recommended CO2 levels for Indoor Air. The levels recommended vary, but most are less than 1000ppm (800 sometimes) or less than 400 above background. Each situation is different and must be evaluated and unlike OSHA PEL levels, these are not harm levels, but "comfort" or "productivity" levels.

That is not your problem ,but as the CO2 increases in a confined space it will suppress the oxygen .
Normal O 20.9%
low alarm point is 19.5% anything below that and u will pass out.
