How does hazard classification work under CLP?
A substance or mixture is classified against the hazard classes in Annex I of CLP: physical (e.g. flammable, oxidising), health (e.g. acute toxicity, skin sensitisation, carcinogenicity) and environmental (e.g. aquatic toxicity). For mixtures, classification uses bridging principles, additivity formulas and cut-off values to derive the hazard from the components.
