The pictograms for labelling chemical products have changed. Prevent workplace injury and diseases by learning more about the pictograms. Chemical products are used every day at work - not just in factories, but also in construction work or in offices - in things like cleaning products, paints, etc. The European Union’s 2009 classification, labelling and packaging (CLP) regulation introduced new warning pictograms. The diamond-shaped pictograms indicate the nature of the hazard(s) associated with the use of a hazardous substance or mixture. On labels, the pictograms are accompanied by signal words, hazard statements, and precautionary statements, as well as product and supplier information.
