  1. 1. Peroxide Formers
  2. 2. • Keep away from light • Test for peroxides prior to distillation for Class B • Purchase with inhibitor for Class C compounds • Minimize exposure to O2, except in presence of inhibitor • Keep diethyl ether in steel cans b/c iron is peroxide inhibitor • Record Date of Receipt • Record Date of Opening
  3. 3. Class A – High Hazard Class B – Concentration Peroxides Class C – Autopolymerizers 3 months 3 months 12 months 12 months or 24 hours without inhibitor 6 months AFTER OPENING AFTER RECEIVING
  4. 4. Class A – High Hazard Class B – Concentration Peroxides Class C – Autopolymerizers Isopropyl Ether Diethyl Ether THF Isopropanol Butadiene Styrene Vinyl Chloride Complete list and more information can be found at : Information on Peroxide-Forming Compounds from Vanderbilt University Medical Center
