Hazard Pictograms (symbols)

Under the Classification, Labelling and Packaging (CLP) regulations [1] new international hazard pictograms came into effect in 2009 replacing the European symbols (see below).

The CLP regulations replaced the Chemicals Hazard Information and Packaging for Supply (CHIP) regulations [2].  The CLP regulation adopts the United Nations’ Globally Harmonised System on the classification and labelling of chemicals (GHS) across all European Union countries.

*Following Brexit, the EU CLP Regulation is retained in Great British law, as GB CLP Regulation and use of the Globally Harmonised System (GHS) of classification and labelling of chemicals will continue with amendments.
