The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an internationally standard, managed by the United Nations, that was set up to replace the assortment of hazardous material classification and labelling schemes previously used around the world. This worker safety initiative provides chemical handlers with important hazard information.
Chemical manufacturers must reclassify their chemicals using the GHS standardised classification criteria.
People of all ages, from children to the elderly, using many different languages and alphabets, belonging to various social groups, including illiterates, come into contact with potentially dangerous products (chemicals, pesticides, etc.). GHS has created a single international hazard warning communication system using standardised colour pictograms.
