organic peroxide storage

Safe storage of organic peroxide

Organic peroxides are thermally unstable substances or mixtures which may give rise to exothermic self-accelerating decomposition under certain conditions. Organic peroxides and their mixtures may violently decompose with a high combustion rate generating a very high heat flux. Depending on the thermal stability organic peroxides may require in addition temperature controlled storage facilities. 

National and regional legislation is typically regulating the storage of organic peroxides.  In those regulations organic peroxides are assigned to different storage groups depending on the burning behavior (speed and heat generation) and sometimes on transport classification. The required measure for storing organic peroxides according to the legislation is typically depending on the assigned storage groups. 

For storing organic peroxides in the correct manner, please obey local, regional and national regulations and contact your local competent authorities.

Regulations and standards (national)

  • Germany: TRGS 741

  • France: official texts can be found on the Aida-Ineris website. They include the nomenclature for classified installations for environment protection defining the quantity thresholds for regulatory constraints, the regulatory order of March 20th 2007 defining the risk groups, and the regulatory orders of November 6th 2007 and November 10th 2008 for installations submitted respectively to authorization and declaration.
