I have sold/worked with dry ice for many years...If you are trying to cool ambient air, I dont see any problems. Wouldnt recommend using it directly in the wort however. But for chilling ambient air, it will work, maybe too well even

I work with dry ice on a daily basis to make cooling baths to control the temperature for various organic reactions. I wouldn't put it into my wort, since it isn't generated under sanitary conditions. You can reach almost any temperature with the correct mixture of dry ice or liquid nitrogen and the correct organic solvent. However, the average Joe can't buy most of the following solvents. Acetone would be the safest bet, but I won't be trying it or ANY of these solvents(and I don't recommend anyone else try it either).

Why can't you put it into a couple sealed plastic bags with a tube attached for the co2 to escape?

ok i am very new to brewing (never done it) but could you maybe put your boiler into a tub of dry ice as an alternative to a wort chiller? i dont really think it would be cost effective though. i dont see it as a concerne for contamination at all considering the very extreme temps and that it is C2O2 which should kill off any organisims not allowed to go dormant 1st
