Occupational exposure to optical radiation in the context of a possible EU proposal for a directive on optical radiation

Occupational exposures to optical radiation are reviewed in the context of a possible EU proposal for a Directive on Optical Radiation. The impact of using available international guidelines for limiting exposure is discussed. Critical groups are identified and observations made on developing technologies. A significant exposure for many people at work comes from the sun. It is unlikely that engineering controls will be effective in managing exposure to this source. However, many other sources of exposure can be controlled at manufacture, potentially reducing the burden on employers. There are a number of potential exposure situations, particularly relating to the use of light emitting diodes, where exposure data is not available. (author)
