What is GHS (Globally Harmonized System)?
The United Nations Globally Harmonized System of Classification and Labelling of Chemicals, which defines common criteria for classifying physical, health and environmental hazards and communicating them through labels and Safety Data Sheets. Labels use standard pictograms, signal words (Danger or Warning), hazard statements (H-codes) and precautionary statements (P-codes). Countries adopt GHS through their own laws, sometimes selecting different revisions or building blocks.
