Classification and labelling system
Authorities should establish classification and labelling systems and specific criteria for classifying a chemical as hazardous. The authorities should then progressively extend these systems and their application. The purpose of these systems is to ensure all chemicals are marked so as to indicate their identity and whether or not they are hazardous. For hazardous chemicals this system shall include the GHS system with specific criteria appropriate for the classification of all chemicals according to the type and degree of their intrinsic health and physical hazards and for assessing the relevance of the information required to determine whether a chemical is hazardous.
