The BAuA Research project F 2437 on "Derivation of occupational exposure limits for airborne chemicals - Comparison of methods and protection levels" analysed the currently used methods to derive occupational exposure limits (OELs) and analogue values in the EU and at national level in Germany. At an international workshop at the BAuA in Dortmund on 5 April 2022 (organised as hybrid event with the possibility to participate online) the authors from FoBiG (Forschungs- und Beratungsinstitut Gefahrstoffe GmbH) presented the project outcome and discussed with more than 190 participants results and conclusions. One of the major observations was that large differences exist between currently used methods for deriving such values. Discussions focused on ways to implement steps towards harmonisation of methods for deriving OELs.
