Globally Harmonized System of Classification and Labelling of Chemicals (GHS, Rev.5)

Globally Harmonized System of Classification and Labelling of Chemicals (GHS, Rev.5)

The GHS addresses classification of chemicals by types of hazard and proposes harmonized hazard communication elements, including labels and safety data sheets. It aims at ensuring that information on physical hazards and toxicity from chemicals be available in order to enhance the protection of human health and the environment during the handling, transport and use of these chemicals.


The GHS also provides a basis for harmonization of rules and regulations on chemicals at national, regional and worldwide level.


The sixth revised edition of the GHS contains various new or revised provisions including, inter alia, a new hazard class for desensitized explosives and a new hazard category for pyrophoric gases; miscellaneous provisions intended to clarify the criteria for some hazard classes (explosives, specific target organ toxicity following single exposure, aspiration hazard and hazardous to the aquatic environment); additional information to be included in the Safety Data Sheets (section 9); revised and further rationalized precautionary statements and a new example in Annex 7 addressing labelling of small packagings.
