Hazardous substance labels in accordance with the GHS regulation indicate toxic and health-endangering substances. The “Globally Harmonized System of Classification and Labeling of Chemicals” (GHS) is a globally uniform labeling system with globally valid hazard symbols. Since December 1st, 2010, substances and since June 1st, 2015, mixtures must be labeled according to GHS with so-called “GHS pictogram stickers”.
