After a bunch of great replies on flammable refrigerators, I have two follow-up questions.

question 1: A colleague asked me to inquire what the general selection criteria are for deciding which chemicals should be stored in a fridge vs. on the unrefrigerated shelf (I suppose this isn't necessarily a safety question). For those that should be refrigerated, what spec should determine that it should be in a flammables refrigerator and not a regular one?  Is it a flash point cutoff or something else?

question 2: The NMR solvents under consideration are CDCl3, d6-DMSO and d4-methanol.  Should these even be in a fridge? Should these specific solvents be in a flammables fridge?

Thanks so much for all of the help!
