UV radiation exposure during welding, Subproject 3 "Requirements for protective components during welding"

Project number: F 2422 Institution: Federal Institute for Occupational Safety and Health (BAuA) Status: Ongoing Project Planned end: 2019-08-31


In a study recently published by the German Welding Society (DVS) entitled "Macroeconomic and sectoral added value from production and application of joining technology in Germany and Europe", therein, a number of about 260,000 welders in Germany in 2011 was mentioned. In Europe, this number counts even one million.

Exposure limit values for incoherent optical radiation are given in the German "Artificial Optical Radiation Occupational Safety and Health Ordinance (OStrV)". Within the scope of a risk assessment the OStrV also applies to the UV exposure for several different welding procedures. As a result, exposure limit values can be exceeded within seconds and protective components have to be used. But up to now, no normative requirements or even a protection concept for protective components have been developed. This project will deal with these deficits, solve them and give recommendations as well as assistance for the design of secure and healthy working environments.

Based on spectroradiometric data, one goal is to modify the existing requirements to protective components with regard to normative regulations. It is of high impact to perform this modification in view of usability and wearing comfort to ensure acceptance among welders.

Measurements on materials for walls and protective equipment will yield in important information for companies so that these will be able to further develop their products with regard to the purpose of safety and health at work places.
