Organic Peroxides: Safe Working Practices

Organic peroxides are a group of carbon based compounds that contain two oxygen atoms joined together. The double oxygen makes them incredibly useful but also incredibly dangerous if not handled and stored correctly.

Following recommended guidance on storing organic peroxides can reduce the number of fires or explosions that are associated with thermally unstable compounds.

Below we provide guidance on safe working practises when dealing with them.

Best Practise Methods

  • Separately list all of the organic peroxide materials you use within your organisation
  • Provide staff with access to the Safety Data Sheets (SDS) for all of the organic peroxides stored and used on site
  • Check the reactivity data and storage requirements sections of the SDS for details of incompatible issues
  • Ensure relevant members of staff understand all of the hazards (fire/explosion, health, corrosiveness, chemical reactivity) of the materials used
  • Create a response plan so staff know how to handle emergencies (fires, spills, personal injury) involving the organic peroxides you work with
  • Wear the appropriate level of Personal Protective Equipment (PPE)
  • Practice good housekeeping, personal cleanliness and equipment maintenance
  • Follow the health and safety guidance as applicable to your role

Organic Peroxide Storage Temperatures

    • Follow the manufacturer’s recommendations on the maximum and minimum storage and use temperatures and take note of the SADT
    • It’s good practice to mark the recommended storage temperature range along with the date that the product was received and first opened on each container of organic peroxide

 

Storage Containers

  • Store organic peroxides in suitable, labelled containers. Only store organic peroxides in containers that the chemical supplier/manufacturer recommends (repackaging can be very dangerous) and make sure all containers are suitably and clearly labelled
  • Always inspect/physically check all incoming containers of organic peroxide to ensure that they are undamaged and properly labelled and always reject any that are defective
  • Protect containers against impact or other physical damage, when storing, transferring or using them and don’t use combustible pallets, such as wood
  • Handle containers safely to avoid damaging them
  • Keep containers closed when not in use
  • Never return unused or contaminated organic peroxides to their original containers
  • Return unopened containers to the proper storage area and opened containers to a dispensing or premixing area at the end of the day

 

Handling Organic Peroxides

  • Store, handle and use organic peroxides in well-ventilated areas and away from incompatible materials
  • Eliminate all ignition sources (sparks, smoking, flames, hot surfaces etc.)
  • Keep the minimum amounts possible (no more than one day’s supply) in the work area
  • Dispense organic peroxides carefully, using compatible equipment, into acceptable containers
  • Do not grind or subject organic peroxides to any type of friction or impact
  • Be careful when performing operations such as distillations or separations that concentrate organic peroxides

Key Points

  • Adhere to the information on your SDS
  • Ensure relevant staff are trained in the correct storage and handling of Organic Peroxides
  • Create a robust emergency response plan
  • Follow manufacturer or supplied advise about safe storage and handling temperatures
  • Store organic peroxides in appropriate, labelled containers
  • Transport carefully
  • Store in well ventilated areas
  • Keep minimum amounts possible in work area
  • Treat with the highest care
