Organic Peroxide Storage Temperatures

Organic peroxide storage temperatures must be adhered to ensure their safe storage and handling. Below we provide you with some advice to safeguard your business and employees.

  1. Follow the manufacturer’s/supplier’s recommendations for maximum and minimum temperatures required for storage and use of each type of organic peroxide you have.
  2. Higher temperatures can be hazardous since they speed up the decomposition rate of organic peroxides.
  3. Some organic peroxides must be kept at low temperatures, in refrigerators, freezers or temperature controlled stores, with that in mind you must ensure the equipment is approved and has the appropriate certification. Storage areas requiring explosion-proof equipment should be zoned accordingly and any electrical equipment ATEX certified.
  4. Ventilation should never be overlooked. Remember it can be required to “remove” peroxide decomposition products that might result from a refrigeration failure.
  5. It can be hazardous to store organic peroxides below the minimum recommended temperatures because some products can become crystallised and shock sensitive. Do not store organic peroxides which are diluted with water at temperatures below 0°C to avoid separating out the pure organic peroxide.
  6. Storage areas need monitoring and alarms that indicate when storage temperatures are higher or lower than required are a must, ideally they will “report” both locally and remotely to ensure a rapid response in the event of a failure or event.
