Product manufacturers communicate the hazards of their products with symbols added to the packaging, which adhere to the CLP Regulation (Classification, Labelling and Packaging) 1272/2008 and are applicable throughout the EU. The symbols are shown in black on a white background inside a red diamond. The goal is that, in the future, the same GHS (Global Harmonised System) marking and classification system will be used all over the world.
