(2)  Article 27 of Directive 67/548/EEC provides that the person responsible for placing dangerous substances on the market must also provide a safety data sheet. (3)  Safety data sheet information is principally intended for use by professional users and must enable them to take the necessary measures as regards the protection of health, safety and the environment at the place of work. (4)  Safety data sheets for dangerous substances and certain preparations, and their supply must comply with the provisions of Commission Directive 91/155/EEC (¥, as amended by Directive 93/112[EC (%).

(6)  Directive 1999/45/EC also introduces a requirement for preparations to be classified and labelled for their effects on the environment. (7) Tt is therefore necessary to amend Directive 91/155/EEC accordingly, as specified in Article 14(2.3) of Directive 1999/45/EC, before 30 July 2002. (8)  Article 4 of Council Directive 98/24/EC of 7 April 1998 on the protection of the health and safety of workers from the risk related to chemical agents at work (four- teenth individual Directive within the meaning of Article 16(1) of Directive 89/391/EEC) () requires employers to determine whether any hazardous chemical agents are present at the workplace, and to assess any risk to the health and safety of workers arising from the presence of those chemical agents, taking into consideration the information provided by the supplier via safety data sheets; it is therefore opportune to amend the Annex to Directive 91/155/EEC accordingly. (9) It is known from recent enforcement activities and studies in the Member States that many safety data sheets are of poor quality and do not provide adequate information for the user; one way of improving the quality of safety data sheets is to improve the guidance given to compilers of safety data sheets set out in the Annex to Directive 91/155/EEC; it is therefore oppor- tune to amend the Annex to Directive 91/155/EEC accordingly; the Commission and the Member States will consider other means by which the quality of safety data sheets can be improved further in future. (10) The measures provided for in this Directive are in accordance with the opinion of the Committee for the adaptation to technical progress of the Directives on the removal of technical barriers to trade in dangerous substances and preparations established under Article 20 of Directive 1999/45/EC, (9 O] L 131, 5.5.1998, p. 11.
