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
