I can remember reading some warning about using dry ice in the
refrigerator or freezer (for an emergency), but I can't remember what
the danger was. Something about the evaporating gas doing something???
Anyone know?
TIA

There was a thread about dry ice here a whiles back, IIRC Sheldon (or
somebody) said that dry ice will freeze and then shatter plastic, etc.
(this was in response to someone asking if they could keep dry ice in a
cooler...). Best to wrap the dry ice in newspapers or whatever to keep
it from contact with interior surfaces...

The gas dealie I know nothing about...

Handle dry ice with gloves. (if it's wrapped heavily in newspaper, you
may can skip this if you handle it gingerly)

It gives off carbon dioxide gas, which is heavier than air and can
suffocate you if in a confined space -- a very small risk if you are at
all careful.

And don't put the dry ice in a strong, tightly sealed container because
it will build up enough pressure to burst the container (perhaps violently)

Best regards,
Bob

Thanks, Gregory and zxcvbob !

Actually dry ice will *freeze* the skin, no burning whatsoever.

Actually it is a burn. A burn is caused by heat travel across an area
separated by two extremely different temperatures. In the case of dry
ice the heat travels from the flesh, across the skin layer, and into
the dry ice. Dry ice is very cold and the heat transfer is rapid,
causing a true burn.

Until you thaw ..... then it burns and blisters like hell.

No, no burning, freezing is not burning... could be blistering but
usually not... typically there isn't any thawing, at those low temps
cell wall integrity is completely demolished, all water is driven out
(kind of like a miniature snow storm) and the flesh simply falls off.
