Globally Harmonized System of Classification and Labelling of Chemicals (GHS)

The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) addresses classification and labelling of chemicals by types of hazards and provides the basis for worldwide harmonization of rules and regulations used, to this end,in various sectors (transport, agriculture, workplace safety, consumer protection and environment protection). It aims at enhancing the protection of human health and the environment during the handling, transport and use of these chemicals by ensuring that the information about their physical, chemical and environmental hazards is available. The fourth revised edition includes new hazard categories for chemically unstable gases and non to flammable aerosols, as well as miscellaneous changes to further clarify some of the criteria and to improve the rationalisation of the precautionary statements.
