Regulations extending the list of hazardous substances and preparations which must not be supplied to the public came into force in Britain on 27 November. 1
The regulations implement the seventeenth amendment of the 1976 EC Directive on the marketing and use of dangerous substances and preparations. This added some two dozen compounds - mainly chromates and benzidine-based azo dyes - to the existing EC lists of carcinogens, mutagens and teratogens, while five existing entries were deleted.
Substances on these lists must not be supplied to the general public, and they, or preparations containing them, must also be labelled with the phrase "restricted to professional users". The new regulations implement these requirements, and also contain a consolidated list of several hundred substances classified at EC level as carcinogens, mutagens or teratogens.
