My references are not to hand, but like many things, it is an
interaction - in this case % of CO2 and time.  That is, you can allow
a lower CO2 concentration if you are able to maintain the exposure
over a longer period of time.  So the thing you'd need to know is
what sort of concentration can you get from X amount of dry ice, and
can you maintain the gas tightness in the stack for the period of
time required.
 
I'll try to remember to look up the reference later.
