Just be careful not to store oxidizers like ether in a refrigerator routinely. It won't be cold enough to prevent formation of peroxides but it could be cold enough to cause them to come out of solution. That would be bad.

We have since installed window A/C units in our two storerooms that could be affected by high temperatures. They are set to a constant temperature. Our building and heating system are old and don't always maintain a constant temperature in all the labs, so sometimes the A/C and heater run simultaneously, but it keeps our storage rooms cool (while heating the labs). We also have a flammable refrigerator that we store several chemicals in, and could be used to temporarily store others if needed.

Has anyone had an event where the temperature in one of these places that neared or exceeded 100 deg. F and is willing to share the experience? Or what you would do in such an event? Any thoughts on relying on flammable storage refrigerators for contingency planning? Thank you, Marjorie Markopoulos EHS Specialist Wright State University marjorie.markopoulos**At_Symbol_Here**wright.edu
