“Many thanks to you for this very good training session (Ecotoxicology & CLP Webinar). The training materials are very good and well presented.” E.C.  Scientific & Technical Affairs Manager, Belgium. 

Gain a thorough overview of the substance and mixture classification for environmental hazards with this popular two-hour training webinar.

Although the focus of this webinar will be on the EU CLP, the underlying principles of classifying and labelling are also applicable for GHS. Any differences between the EU CLP and GHS will be highlighted during the session.

Throughout the session examples of classification for the respective hazard classes will be used to illustrate the theory – with the opportunity to ask lots of questions!

Webinar outcomes

    • Understand the key components of the aquatic environment and why environmental fate data is needed
    • Explain what is meant by classification and why it is important to do
    • Outline the main difference between CLP and GHS (including the GHS hazard categories which have not currently been included in CLP)
    • Explain what is meant by harmonised classification and self-classification
    • Explain what is meant by bridging principles and how these are used
    • Explain when existing mixture test data can be used and the scenario where it should not be used, and the reason for this
    • Explain the differences between aquatic acute toxicity and chronic acute toxicity hazard class and what is meant by ‘category’
    • Explain how multiplication factors (M-factors) are derived and when they should be used
    • Explain the differences between generic cut off limits, specific concentration limits and generic concentration limits and how these are used
    • Outline important considerations when choosing data for classification purposes (including the types of data which could be used)
    • Classify a substance and mixture for each of the environmental hazard classes

Who should attend

    • Regulatory affairs (chemical registration work)
    • Authors and recipients of safety data sheets (SDS)
    • Anyone involved in classification and labelling in accordance with EU CLP/GHS
    • Regulatory authorities
    • Anyone who wants to learn more about the classification and labelling process

Training resources included:

    • Training handbook complementing the webinar and including practice questions and answers to test your understanding of toxicology basics.
    • Copy of all slides used during the training
    • Copy of the live recording
    • Attendance on the two- hour live training course
    • A free 15 -minute follow up session
    • Certificate of attendance available upon request

About This Webinar

A unique feature of this training webinar is that you are encouraged to ‘raise your hand’ and put questions forward throughout the training – just as you would in a classroom environment

In order to gain maximum benefit from this webinar an introductory/basic ecotoxicology background would be useful.
