Myrkytystietokeskuksille tehtävän ilmoituksen muoto

The Poison Centres Notification (PCN) format structures the information on hazardous mixtures classified for health or physical hazards. This information has to be submitted to the Member States appointed bodies. The format is XML-based and defined by the requirements laid out in Annex VIII to the CLP Regulation.

The information to be submitted includes the full chemical composition, toxicological information, relevant product and mixture details including the intended use (EuPCS), in addition to the label elements such as the unique formula identifier (UFI). The PCN format aims to harmonise and ensure consistency of the information available to poison centres in cases of poisoning incidents in the EU.

The PCN format is compatible with IUCLID, a tool developed by ECHA in collaboration with the OECD, which promotes the harmonisation of chemicals data. You can find additional information about this tool on the IUCLID website.

To help with the IT implementation of this format, the following is available:

  • PCN format: the format is made available as a set of XML schema definition files (XSDs). There is also a data model that shows all relevant fields and their interconnections.
  • Part A - Preparing a PCN dossier: this document provides a technical background and offers a practical guide to the industry on how to encode, prepare and complete a dossier compliant with the PCN format. The XML content and the inner structure of the PCN format is explained in a simple manner avoiding technical details or jargons. The validation rules applied on top of the IUCLID format and the picklist elements used are also provided as a separate annexes.
  • Part B - Developers' guide to the IUCLID format: in IUCLID, the exchange of chemical information is facilitated via a zip/archive file with the extension .i6z (IUCLID 6 zip). The information can be exported from one IUCLID 6 installation and imported into another. This file contains information concerning all (inter)related IUCLID 6 entities (documents and attachments), in a well-defined and structured format. This guide explains the structure of the IUCLID file in order for developers to build other systems than IUCLID 6 which can generate this format.
  • Examples of Poison Centre Notifications are provided below:

    Note: the PCN examples, provided in i6z format are compatible with the release of IUCLID 6.3 and 6.4, respectively published in October 2018 and 2019 on the IUCLID 6 website.
