European hazard symbols

From Wikipedia, the free encyclopedia

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

GHS hazard pictograms[edit]

  • 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)

Former hazard pictograms (1999–2007)[edit]

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 § References).

Oxidizing (O) Oxygen, potassium nitrate, hydrogen peroxide, nitric acid, potassium permanganate
Toxic (T) Sulfuric acid, TNT, Nitroglycerin, carbon disulfide, methanol, ammonia, formaldehyde
