Dry Ice Hazard

[Melissa Melan]

We "keep" our dry ice in a -80 chest freezer.  It lasts a while but not
indefinitely and so the CO2 tends to collect down in the bottom of the freezer.
Fortunately we don't keep cell culture samples in there (i.e. no pH worries)
but if you don't remember to hold your breath when reaching for something down
in the bottom of the freezer....you could be in for a suffocating suprise.
