Most workplaces contain artificial optical radiation sources and Directive 2006/25/EC lays down minimum health and safety requirements regarding exposure of workers to such sources. The European Commission non-binding guide to good practice for implementing Directive 2006/25/EC pinpoints applications posing minimal risk and provides guidance on others. It sets out an assessment methodology and outlines measures to reduce hazards and check for adverse health effects. This publication will be available in printed format in English, French and German and in electronic format in all other EU official languages. A CD containing 22 language versions (Catalogue number: KE-32-11-704-1X-Z, ISBN 978-92-79-19829-8) is also be available.
