Want to learn how to classify and label substances/mixtures (CLP/GHS)  in a live streaming classroom?


This brand new live streaming training class (6 hours – split over three sessions) is perfect for anyone who wishes to avoid the current problems and cost of travelling but wants something more substantial than a webinar or eLearning course.

Broken into three separate 2-hour sessions this live streaming class provides a thorough introduction into classification and labelling substances and mixtures in accordance with CLP/GHS.  It is also useful if you simply want to refresh existing skills.

This live streaming class will cover all hazard classes and the classification criteria for substances and mixtures. Worked examples and set exercises will be provided during the session to help reinforce the learning.


Small group sizes and live discussions

In order to ensure optimal involvement/interaction between the trainer and delegates, there will be only a limited number of places available for each course.

Furthermore, all delegates are encouraged where possible, to use a headset/microphone so they can interact (i.e. ask/answer questions) with the other delegates and trainer.


What will be covered in each session

SESSION 1 – Introduction and classification of physical hazards for substances and mixtures (2 hours)

Session 1A – Introduction 

  • The roles and obligations under GHS / CLP with regards to classification and labelling
  • Hazard classes, categories, hazard statements and precautionary statements
  • Outline the additional hazard classes which may be used in different regions of the world when implementing GHS.

Session  1 B – Classification of a substance and mixture

  • Useful data sources of data and assessment of data reliability, including specific mixture test data.
  • Harmonised versus self-classification and minimum classifications with examples
  • Use of bridging principles for classification purposes.
  • Additivity principle (including what is meant by non-additivity)
  • Concentration limit/cut off values/ calculation method

Session 1C – Classification for Physical Hazards  (Substances and mixtures)

In each case, definitions, testing approach and criteria for classification are covered.

  • 2.1 – Explosives
  • 2.2- Flammable gases
  • 2.3 Aerosols
  • 2.4  Oxidizing gases
  • 2.5 Gases under pressure
  • 2.6 Flammable liquids
  • 2.7 Flammable solids
  • 2.8 Self-reactive substances and mixtures
  • 2.9 Pyrophoric liquids
  • 2.10 Pyrophoric solids

Set examples and exercises will be used to illustrate the theory.


SESSION 2 – Classification of substances and mixtures (2 hours)

Session 2A – Classification for Physical Hazards  (Substances and mixtures)

In each case, definitions, testing approach and criteria for classification are covered.

  • 2.11 Self-heating substances and mixtures
  • 2.12 Substances and mixtures which, in contact with water emit flammable gases
  • 2.13 Oxidising liquids
  • 2.14 Oxidising solids
  • 2.15 Organic peroxides
  • 2.16 Corrosive to metals
  • 2.17 Desensitised explosives

Session 2B  – Classification for Health Hazards  (Substances and mixtures)

In each case, definitions and criteria for classification are covered.

  • 3.1 Acute Toxicity
  • 3.2 Skin corrosion/Irritation
  • 3.3 Serious eye damage/eye irritation
  • 3.4 Respiratory or skin sensitization

Set examples and exercises will be used to illustrate the theory.


SESSION 3 – Classification for health and environmental hazards                (2 hours)

Session 3A  – Classification for Health Hazards  (Substances and mixtures)

In each case, definitions and criteria for classification are covered.

  • 3.5 Germ cell mutagenicity
  • 3.6 Carcinogenicity
  • 3.7 Reproductive toxicity
  • 3.8 Specific target organ toxicity – single exposure
  • 3.9  Specific target organ toxicity – repeated exposure

Set examples and exercises will be used to illustrate the theory.

Session 3B – Classification for environmental hazards  (substances and mixtures)

  • Explain why classification is primarily based on the aquatic compartment.
  • Which test organisms are used and why (trophic levels).
  • How and why data related to rapid degradability and bioaccumulation is used in classification.
  • Hazard classes and categories for environmental hazards.
  • The purpose of the safety net classification (chronic category 4).
  • Explain the purpose of M factors and how these are used.
  • The approach that is taken to using the criteria for classification for acute and chronic aquatic effects respectively (substances and mixtures).
  • Explain when test data on the mixture may be used for classification.
  • Explain what is meant by the summation method and how it is used.

Set examples and exercises will be used to illustrate the theory.
