Webinar: ECHA Chem – Exploring the ECHA website to help with classification of substances and mixtures

    Webinar Overview

    We have come to accept that there is a wealth of information at our fingertips to help us find details on chemical substances thanks to the internet for these resources, the European Chemicals Agency (ECHA) database is perhaps the largest and most comprehensive source of information on substances in the World.

    The layout and format of ECHA Chem is different to the older website that is being wound down. Sometimes it also seems there is too much information, but there are also limitations of the data.

    So, the challenge is to be able to use the website efficiently to find the information we need, and to be confident that what we have found is indeed reliable. There is also the danger of falling down the rabbit hole of hyper-links and references and getting in so deep that we have forgotten what we set out to look for. Do we need to check every single data entry for a registered substance, or just look at summary information?

    This is the first of two planned webinars exploring the information held in ECHA Chem. In this event, we will be looking at the classification of substances to review the existing data that may be presented as ‘harmonised’, or ‘industry’ generated, and then whether based on REACH Registrations or CLP Notifications.

    We need to have confidence in the quality of information presented and how to judge reliability of data. And if this is all the information we can find, do we accept it when preparing our own safety data sheets (SDSs) or classifying chemicals?

    Key Takeaways

    • Navigating ECHA Chem.
    • Considering different types of CLP Classification.
    • REACH-based data.
    • Is the majority always right?

    Why Attend?

    To be able to make informed decisions on potential hazards of substances used on their own or in mixtures and to be able to manage risk, as well as communicate the findings on SDS, it is essential to be confident in the source of information being used.

    Data reliability impacts:

    • Authoring SDS and CLP labels for substances and mixtures;
    • Transport classification and labelling;
    • COSHH assessments and workplace safety;
    • Research and development of new products.
