We typically go with the pass/fail method as well. If peroxide forming solvents have not been tested within their recommended testing period (per the SDS, Prudent Practices, etc), we treat them as if they contain peroxides. We once found a can of isopropyl ether that had been sitting around for years, and no peroxides were detected (this was evaluated by our waste vendor’s “high haz” team). We’ve also found relatively “young” ether that did test positive. Never know what you’ll find hidden away, so I like to fall on the side of caution when handling these.

Does anyone have a testing program in which peroxide forming chemicals are tested?  If so, what methodology are you using?  Do you have a threshold value for disposal, and is it for all peroxide formers or are there different thresholds specific to certain chemicals?

 

Thanks for your help.
