All registration dossiers of Precious Metals cyanides have been registered and can be submitted by co-registrants.. The maintenance of these dossiers will start in 2018.

The identified uses of the precious metals cyanides substances registered by the EPMF have been covered in Exposure Scenarios (ES) when needed. These Exposure Scenarios are not only a requirement for the REACH registration dossiers but must also be communicated down the supply chain to downstream users (DU) via the Extended Safety Data Sheets (eSDS).

Once a DU has received the eSDS, they need to:

  • Check whether it covers their use
  • Check whether the conditions of safe use correspond to the operational conditions and risk management measures implemented at their site.

This section of the website has been developed to assist in the communication along the supply chain. It provides to all EPMF members but also downstream users and potential new co-registrants with the most recent list of identified uses and versions of existing DU ES extracted from the chemical safety reports (CSR) of precious metals cyanides covered by the EPMF.

You will find below the list of identified uses (and Exposure Scenarios when relevant) by substance.

 Potassium dicyanorgentate uses
 Potassium dicyanoaurate uses
 Silver cyanide uses

If your use is not covered or if you need more information, please do not hesitate to  contact us.
