European hazard symbols

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)

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.

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).

Europe standard hazard pictograms for labelling – Europe UE 67/548/EEC, 1999/45/EC
Hazard pictogram & mention, code	Substances examples
Explosive (E)	TNT, acetone peroxide, nitroglycerin, picric acid
Extremely Flammable (F+)	Hydrogen, acetylene, propane, butane, diethyl ether, carbon disulfide, acetaldehyde
Highly Flammable (F)	Ethanol, acetone, gasoline, hexamine, methanol
Oxidizing (O)	Oxygen, potassium nitrate, hydrogen peroxide, nitric acid, potassium permanganate
Toxic (T)	Sulfuric acid, TNT, Nitroglycerin, carbon disulfide, methanol, ammonia, formaldehyde
Very toxic (T+)	Prussic acid, nicotine, carbon monoxide, white phosphorus
Harmful (Xn)	Hexamine, butane, naphtha, acetaldehyde
Irritant (Xi)	Sodium hypochlorite, acetone, ethanol
Corrosive (C)	Sulfuric acid, Nitric acid, sodium hydroxide, ammonia, White phosphorus
Dangerous for the environment (N)	Sulfuric acid, turpentine, lead, mercury, Crude oil

The 'n' in Harmful (Xn) stands for the French word nocif (harmful) and the Italian word nocivo (noxious).
