It might be a problem, depending on how air tight the room is (they usually
are tight), and how much is stored in there and for how long.  I have heard
of a case where the CO2 buildup was significant and someone who went into
the room fainted.  A -70 freezer or an insulated storage box in an open
area is probably better.
