A detailed overview of ecotoxicology with a close look at CLP and GHS

The European Regulation (EC) No 1272/2008 on classification, labelling, and packaging of substances and mixtures (often called CLP) is based on the United Nations Globally Harmonised System (GHS) and came into force in January 2009.

Although the focus of this webinar will be 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.

To gain maximum benefit from this webinar it would be useful to have some basic knowledge of ecotoxicology.

Note: Throughout the session examples of classification for the respective hazard classes will be used to illustrate the theory – therefore to gain maximum benefit from this webinar it would be useful to have some basic knowledge of ecotoxicology, as well as a pencil, some paper, and a calculator.

Attendees will learn how to:

  • Explain the what is meant by classification and why it is important to do
  • Outline the main difference between CLP and GHS (including the HS 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 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 mixture for each of the environmental hazard classes
