12 Hazardous substances basics WHAT ARE THE CLASSIFICATION CRITERIA FOR HAZARDOUS SUBSTANCES? The number of hazardous substances with diverse properties and characteristics is manifold and poses corresponding risks. For this reason, the labelling of hazardous materials has been standardised worldwide and implemented in Europe through the CLP Regulation. GHS (Globally Harmonized System of Classification, Labelling and Packaging of Chemicals): Globally uniform system for classifying chemicals and labelling them on packaging and in safety data sheets. The labelling methods for hazardous substances that applied in the EU until 2015 have been replaced. In the GHS, hazard pictograms replaced the hazard symbols with their hazard designations; where appropriate with a common signal word („Caution“ or „Danger“). In combination with the Hazard and Precautionary Statements, the pictograms provide information about ››› the type and severity of the hazard (H-phrases (Hazard Statements) as well as additional EUH-phrases (special hazards)) and ››› the differentiated safety instructions for prevention, reaction, storage and disposal of the hazardous substances (P-phrases (Precautionary Statements)). O (EG) 1272/2008 CLP (Regulation on Classification, Labelling and Packaging of Substances and Mixtures): The regulation is the European implementation of the worldwide GHS system and is equally and directly valid in all member states. Adaptation to technical and scientific progress are made periodically. These adaptations are mainly concerned with corrections to terminology and additions to the list of harmonised classification and labelling of dangerous substances in Annex VI: Acute toxicity – Category 1, 2, 3 Corrosive – Category 1 Flammable – Category 1, 2, 3 Flammable (oxidising) – Category 1, 2, 3 Explosive Compressed gases Hazardous to the environment Hazardous to waters Harmful to ozone layer Acute toxicity – Category 4 Corrosive – Category 2 Skin sensitising Targeted organ toxicity – Category 3 CMR – Category 1A, 1B, 2 Respiratory sensitising Targeted organ toxicity – Category 1, 2 Aspiration hazard Please observe local legislation and regulations. Hazard pictograms according to GHS/CLP The EU CLP Regulation is still applicable to the UK and has been retained in GB law as GB CPL. This means that Great Britain continues to adopt GHS, independently of the European Union.
