of 29 May 1990
on the minimum safety and health requirements for work with display screen equipment (fifth individual Directive within the meaning of Article 16 (1) of Directive 87/391/EEC)
THE COUNCIL OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Economic Community, and in particular Article 118a thereof,
Having regard to the Commission proposal ( 1 ) drawn up after consultation with the Advisory Committee on Safety, Hygiene and Health Protection at Work,
In cooperation with the European Parliament ( 2 ),
Having regard to the opinion of the Economic and Social Committee ( 3 ),
Whereas Article 118a of the Treaty provides that the Council shall adopt, by means of Directives, minimum requirements designed to encourage improvements, especially in the working environment, to ensure a better level of protection of workers’ safety and health;
Whereas, under the terms of that Article, those Directives shall avoid imposing administrative, financial and legal constraints, in a way which would hold back the creation and development of small and medium-sized undertakings;
Whereas the communication from the Commission on its programme concerning safety, hygiene and health at work ( 4 ) provides for the adoption of measures in respect of new technologies; whereas the Council has taken note thereof in its resolution of 21 December 1987 on safety, hygiene and health at work ( 5 );
Whereas compliance with the minimum requirements for ensuring a better level of safety at workstations with display screens is essential for ensuring the safety and health of workers;
Whereas this Directive is an individual Directive within the meaning of Article 16 (1) of Council Directive 89/391/EEC of 12 June 1989 on the introduction of measures to encourage improvements in the safety and health of workers at work ( 6 ); whereas the provisions of the latter are therefore fully applicable to the use by workers of display screen equipment, without prejudice to more stringent and/or specific provisions contained in the present Directive;
Whereas employers are obliged to keep themselves informed of the latest advances in technology and scientific findings concerning workstation design so that they can make any changes necessary so as to be able to guarantee a better level of protection of workers’ safety and health;
Whereas the ergonomic aspects are of particular importance for a workstation with display screen equipment;
Whereas this Directive is a practical contribution towards creating the social dimension of the internal market;
Whereas, pursuant to Decision 74/325/EEC ( 7 ), the Advisory Committee on Safety, Hygiene and Health Protection at Work shall be consulted by the Commission on the drawing-up of proposals in this field,
HAS ADOPTED THIS DIRECTIVE:
