GHS (Globally Harmonized System)

GHS stands for the “Globally Harmonized System” of classification and labeling of chemicals. GHS defines and classifies the hazards of chemical products and communicates health and safety information on labels and safety data sheets. The goal is that the same set of rules for classifying hazards, and the same format and content for labels and safety data sheets (SDS) will be adopted and used around the world.
