UV radiation stress in welding, Subproject 1 "Determination of UV exposure during welding"

Project number: F 2368 Institution: Federal Institute for Occupational Safety and Health (BAuA) / Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA) Status: Completed Project

Description:

In a study by the German Welding Society (DVS) "Macroeconomic and sectoral value added from the production and application of joining technology in Germany and Europe" about 260,000 welders were named for the year 2011 in Germany, nearly a million were named for Europe.

Binding limits are set in the Regulation on the protection of workers from the hazards of artificial optical radiation (OStrV), compliance within the scope of risk assessment must be examined. This also applies to the UV exposure during welding.

For a thorough risk assessment, the available data on UV radiation emission of various welding processes is insufficient. In addition, the actual exposure time is particularly important. Information on the exposure time is also insufficient, so far.

For this purpose experimental studies in a welding Technical Education and Research Institute and in establishments have to be carried out, taking into account the radiation relevant parameters.

From this, a model for the calculation of the UV radiation emission should be developed and be validated on the practical usefulness by measurements in factories.
