What is GHS ?

GHS stands for Globally Harmonized System of Classification and Labeling of Chemicals.

The GHS is an initiative by the United Nations aiming to harmonize chemical hazard communication. This includes harmonized criteria for classification of substances and mixtures according to their physical, health, and environmental hazards, as well as harmonized hazard communication elements.

The first version of GHS was published in 2003 and updated each 2 years since.
