European hazard symbols


European hazard symbols for chemicals are pictograms defined by the European Union for labelling chemical packaging and containers. They are standardised currently by the CLP/GHS classification.

Chemical warning signage

Directive 92/58/EEC provides several safety signs for identifying dangerous materials and areas where they are handled and stored.

Former hazard pictograms (1967–2017)

The previous hazard symbols for chemicals, were introduced in the Directive Directive 67/548/EEC, in 1967, and required to be adopted no later than 1 January 1970. The symbols were also included as a part of Directive 1999/45/EC. The symbols were replaced from 1 December 2010 to 1 June 2017, via a gradual phaseout. After 1 June 2017, Directive 67/548/EEC symbols were no longer allowed to be used.
From 1967 to 2017, these symbols were used for labeling containers and piping systems containing dangerous substances/mixtures. These symbols could also be used to identify areas where dangerous substances/mixtures were being stored in large quantities, as an alternative to the yellow triangular Directive 92/58/EEC warning signage.
