It is ok to store water sensitive reagents (pyrophorics too) inside an explosion proof refrigerator. Make sure your reagent bottle is under nitrogen atmosphere and cap is closed properly. You may also apply a Teflon tape around the cap and use a secondary containment inside refrigerators main compartment to avoid the sliding of the reagent bottle.
I read some Protocols for Safe Use of Pyrophoric/Water-Reactive Reagents mentioned “When refrigeration of materials is required, materials must be stored in an approved explosion-proof refrigerator/freezer.” As we all know, even the explosion-proof refrigerator/freezer cannot provide dry environment.
Can you share your experience on storing pyrophoric, flammable, and water-sensitive substances such as tBuLi solution in pentanes at low temperature? Great Thanks!
