Peroxide Formers - Questions


I would like to know how folks are handling peroxide formers.   Some background on my program is that we have 2 lists.   Group A – we require disposal after 3 months from opening (i.e. Sodium amide).  And Group B – we require disposal 12 months after opening and 24 months after receipt (whichever comes first) (i.e. ether, THF…etc.).  

Specifically, I would like to know what folks do for the following:

1.      A researcher identifies a peroxide former is past the expiration date.  What do they do?

a.       Call EHS

b.      Do you have date ranges that then trigger EHS.   For example, if THF is 1 year past its required disposal date then do they call EHS.   But if the date is within 1 year past the disposal date then they follow normal waste disposal guidelines.

2.      What are your timeframes for requiring folks to contact EHS?

a.      Group A

b.      Group B

3.       Do you have timeframes for when EHS would consider the material a “High Hazard” and call in a High haz waste contractor?

4.      Or, do you rely on visual cues and knowledge of the specific chemical.

Your feedback is appreciated.    Thanks
