LIST OF R-PHRASES

'R-phrases' (short for 'Risk Phrases') are defined in Annex III of European Union Directive 67/548/EEC: ''Nature of special risks attributed to dangerous substances and preparations''. The list was consolidated and republished in Directive 2001/59/EC, where translations into other EU languages may be found.
These risk phrases are used internationally not just in Europe and there is an ongoing effort towards complete international harmonisation. ''(Note: missing R-number combinations indicate phrases that were deleted or replaced by another phrase.)''
