Hello All,

 

I have a collaborator who is storing organic peroxides, solid and li quid, in a walk-in refrigerator/freezer.  They have done so for a number of years.  One of the new organic peroxides is a liquid with a low flashpoint (class IB flammable liquid).  At our facility, an y flammable liquids that require refrigeration are stored in flammable-safe refrigerators.  I have seen the walk-in refrigerator in question on a previous occasion and was not impressed by the housekeeping--spills on t he floor that had not been cleaned up, poor organization and poor lightin g.  I do not have juristiction over this space, but want to offer advice that pertains specifically to walk-in size refrigerators or cold roo ms.  I'm sure that one of the arguments that this collaborator will present is that the walk-in is large enough to offer sufficient dilu tion to prevent an LEL from developing.  Any regulations, stories , advice or help would be wonderful.  In addition, how does one address the issues that these materials are both flammable and oxidizers, when there may be storage with other flammable liquids--should there be en tirely separate storage?
