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.
