European hazard symbols

The Hazard symbols for chemicals are pictograms defined by the European community for labeling chemical packagings (for storage and workplace) and containers (for transportation). They are standardized currently by the CLP/GHS classification.

CLP & ADR / GHS hazard pictograms

European hazard sign, saying Corrosive (CLP/GHS) [GSH05])
  • The European Union CLP Regulation (for "Classification, Labelling and Packaging") was introduced through the European directives (EC) N°1272/2008. It is based on the GHS system, to secure for physical, health and environement hazards.

See main article GHS hazard pictograms, that lists also some Europe-specific hazard statements (EUHxxx) besides the standard GHS Hazard phrases (H) and Precautions advices (P).

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