Part 1: Introduction to CLP/GHS and why classification is important

    This will cover the underlying principles of classification and labelling for environmental hazards. It will also look at where the key differences between CLP and GHS occur and the reason for this.


    Part 2: Hazard classes and categories

    The environmental hazard classes which need to be considered for classification and labelling purposes are identified and explained. Data source and reliability will also be included (that is, useful sources of data and things to consider when using data for classification purposes). Other topics to be discussed include:

    • Environmental hazards
    • Aquatic toxicity (acute and chronic)
    • Hazards to the ozone layer

    Part 3: The classification process

    This section will look at the way in which classification is undertaken, and will cover:

    • Harmonised classification vs Self-classification - where information on harmonised classifications is found and how it should be used, and what is meant by self-classification and how this is accomplished.
    • Application of the hazard class criteria for classification - how the hazard criteria should be applied and points to consider. In addition, for mixtures, the use of existing data, bridging principles and concentration limits and calculation methods
    • Multiplication factors (M-factors) and how these should be used
