List A chemicals should be tested for peroxide formation before using or discarded after 3 months.
* Indicates a peroxide former when stored as a liquid monomer.
| Chloroprene *
List B chemicals should be tested for peroxides before distillation or evaporation and tested for peroxide formation or discarded after 1 year.
|Diethylene glycol dimethyl ether (diglyme)|
|Other secondary alcohols|
List C chemicals should be tested for peroxide formation or discard liquids aftter 6 months; and gases after 1 year.
** Can form explosive levels of peroxides if stored as a liquid. When stored as gas, peroxide accumulation may cause autopoly- merization.
