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.

Last spring our heating system malfunctioned and temperatures rose to
over 100 degrees.  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.

Does anyone have procedures or guidelines for temperature control in
chemistry labs or chemical storage facilities and is willing to share
plans, i.e. in the event of an HVAC failure?  

Has anyone had an event where the temperature in one of these places
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

Thank you,
