European Organic Peroxide Safety Group (EOPSG)

PERGAN is a member of EOPSG and with this brochure we would like to give you a deeper insight in safe handling and transport operations of Organic Peroxides in road and sea transport. The described procedures and equipment, supplementary to the legal requirements, represent the standard practices of the authors of this guide.


Storage Temperatures

Organic Peroxides are more or less stable products that decompose under the influence of heat. To prevent a loss of quality during storage it is important that the recommended maximum storage temperature is not exceeded and the minimum storage temperature not breached.


The SADT is the lowest temperature at which a self accelerating decomposition may occur. This temperature must be avoided at all costs.

Emergency temperature

The emergency temperature is derived from the SADT. It is the temperature at which emergency actions have to be taken.

Control Temperature

The control temperature is also derived from the SADT. The control temperature is the maximum temperature at which the product can be transported safely.


The transport of organic peroxides classified UN 3111 to UN 3120, as well as Azo compounds under UN 3234 and 3236 has to be temperature controlled.


As an alternative to our standard cardboard box, pail, drum and polyethylene container, we can supply certain initiator formulations in reusable stainless steel IBC (up to 1.25m³ volume). Packaging in IBCs offers obvious ecological benefits as well as gains terms of logistics by allowing automated and faster handling.

Packing scheme

Here you can see the form-fitting and appropriate standard packaging scheme by choosing the pallet size CP1, CP2 and CP3 and the type of packaging.
