I have a acquired a very large chest freezer to use as a ale fermentation chamber. I understand the lifting in/out aspect of this, but that's not of concern to me. I was just wondering about the ventilation of the co2 from the freezer. Does any type of ventilation need to be installed or should I just not stick my head in the freezer and start breathing. Also would keeping my finished cornys (ales) in here be ok? Thanks all!
That wouldn't hurt you. A few breaths of co2 is not a concern as it is not toxic. What is a concern is if you had your head in there for more than a few moments because you wouldn't be getting oxygen.

I definitely learned the hard way (a few times) to open the chest freezer and let it "air out" a bit before sticking my whole upper half in there to wrestle a carboy out.
