Hi Danny,
There is no time limit when the depth does not exceed 33 Ft. You can leave
for ever at 30 Ft breathing air with a decompression for safety to go back
to the surface, although decompression sickness is impossible from 33 Ft or
less.
Air is safe to a depth of 50 Feet for saturation missions up to 7 days, and
requires a decompression to go back to the surface.
I recommend you the most complete and excellent book on underwater habitats:
