Where CAS 87-86-5 appears: every table entry that prints it among its identifiers, in the newest version of each act this record holds, and every recorded change to those entries. Many entries name a group of substances and print no number, so absence here is not absence from the law. Not legal advice.

Transitional provisions: By way of derogation until 31 December 2008 France, Ireland, Portugal, Spain and the United Kingdom may chose not to apply this provision to substances and mixtures intended for use in industrial installations not permitting the emission and/or discharge of pentachlorophenol (PCP) in quantities greater than those prescribed by existing legislation: (a) in the treatment of wood. However, treated wood shall not be used: inside buildings whether for decorative purposes or not, whatever their purpose (residence, employment, leisure), for the manufacture and re-treatment of: (i) containers intended for growing purposes; (ii) packaging that may come into contact with raw materials, intermediate or finished products destined for human and/or animal consumption; (iii) other materials that may contaminate the products mentioned in (i) and (ii); (b) in the impregnation of fibres and heavy-duty textiles not intended in any case for clothing or for decorative furnishings; (c) by way of special exception, Member States may on a case-by-case basis, permit on their territory specialised professionals to carry out in situ and for buildings of cultural, artistic and historical interest, or in emergencies, a remedial treatment of timber and masonry infected by dry rot fungus (Serpula lacrymans) and cubic rot fungi. In any case: (a) Pentachlorophenol used alone or as a component of mixtures employed within the framework of the above exceptions must have a total hexachlorodibenzoparadioxin (HCDD) content of not more than two parts per million (ppm); (b) these substances and mixtures shall not: be placed on the market except in packages of 20 litres or more; be sold to the general public. 3. Without prejudice to the implementation of other Community provisions concerning the classification, packaging and labelling of dangerous substances and mixtures, the packaging of substances and mixtures covered by paragraphs 1 and 2 shall be marked clearly and indelibly: Reserved for industrial and professional use. This provision shall not apply to waste covered by Directives 91/689/EEC and 2006/12/EC. |
