European hazard symbols

• The European Union CLP Regulation (for "Classification, Labelling and Packaging") was introduced as EC Regulation 1272/2008. It is based on the GHS system, to secure for "physical, health and environment hazards".

ADR European hazard sign, meaning highly flammable (33) — gasoline (1203)

• The European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) fixed harmonised pictograms for transportation. Vehicles carrying dangerous goods have to be fitted with orange signs, where the lower number identifies the substance, while the upper number is a key for the threat it may pose. See former pictograms below.

Europe 1999 – 2007

The hazard symbols for chemicals were defined in Annex II of Directive 67/548/EEC. A consolidated list with translations into other EU languages was found in Directive 2001/59/EC (See the links section).
