Yep.. . But... As % CO2 goes up you could potentially displace the O2 in the air. CO2 doesnt harm you, but the lack of O2 sure can. Experience for many has proven that this wont be an issue in a cooler in a car, as it'll take a long while for the CO2 to completely sublimate and no car will be airtight for that long.

You see this with liquid nitrogen, traveling in a car or storing in a small area without a Dewar could be deadly, despite N2 being completely inert and technically as "harmless" as CO2.

Then there's the question of will the offgas even be enough to cause a problem, which is, as you said, no.


Sorry. Slow morning.
