Safety first

and environmental conservation for PERGAN out of responsibility

Organic peroxides are highly reactive chemicals. Therefore, they are - determined by national and international regulations - to some extent as dangerous materials (flammable, may cause fire and partly able to explode). The manufacturing, transport, storage, handling and last but not least disposal of organic peroxides requires strict precautions. We have made considerable investments into safety to eliminate risks, avoid faults and protect people and the environment from becoming endangered. Naturally, we provide our customers with support in any kind of safety, handling, or storage issue.

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.


SADT (Self Accelerating Decomposition Temperature)
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 polyethylene containers we can supply certain initiator formulations in re-usable stainless steel IBCs. This type of packaging offers obvious ecological benefits as well as gains in terms of logistics by creating automated and faster handling.
