The issue here isn't that the stirrer is being run in the refrigerator
or that the fridge door is slightly ajar (unless there is a cut-out in
the door seal). The problem lies in the presence of flammable vapors
building up in the confined space with the stirrer as ignition source.
No flammable vapors, no problem. This is why refrigerators for chemical
storage are so expensive. They are designed to minimize contact of
flammable vapors within to ignition sources from the mechanism of the
fridge. If you need to stir something cold with a low flash point a
better alternative might be to use an ice bath or chiller.
