Hello All,

 

I have a collaborator who is storing organic peroxides, solid and liqu id, 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 fl ashpoint (class IB flammable liquid).  At our facility, any flammable liquids that require refrigeration are stored in flammable-safe refrigerato rs.  I have seen the walk-in refrigerator in question on a previous oc casion and was not impressed by the housekeeping--spills on the floor that had not been cleaned up, poor organization and poor lighting.  I do no t have juristiction over this space, but want to offer advice that pertains specifically to walk-in size refrigerators or cold rooms.  I'm sure t hat one of the arguments that this collaborator will present is that t he walk-in is large enough to offer sufficient dilution to prevent an LEL f rom developing.  Any regulations, stories, advice or help would be won derful.  In addition, how does one address the issues that these mater ials are both flammable and oxidizers, when there may be storage with other flammable liquids--should there be entirely separate storage?

 

regards,
