Binding occupational exposure limit values (OELs) of the European Commission

The announcement in the German Federal Labour Gazette (2006) No 4, p. 46, makes dynamic reference to the EU's binding occupational exposure limit values. The values in question are the atmospheric limit values for 16 substances stated in the table. The list was updated at the end of December 2017 by Directive 2017/2398 (to be transposed into national law by 17 January 2020). The binding EU occupational exposure limit values must be adopted as minimum standards by the Member States. The EU binding occupational exposure limit values are not limits (AGWs) in the sense of Section 2 (8) of the German Ordinance on hazardous substances (GefStoffV), below which acute or chronic harmful effects upon health need not generally be anticipated. They are not therefore listed in TRGS 900 technical rules for hazardous substances.

In response to a proposal by the AGS Committee for Hazardous Substances, the German Federal Ministry of Labour and Social Affairs (BMAS) has issued other assessment criteria for numerous substances for which EU occupational exposure limit values exist. Additional measures are required where these criteria are exceeded. These national assessment criteria are also stated in the table. During the definition of measures and protective measures, consideration must be given to other aspects including the provisions and requirements of the relevant substance-specific Technical Rules for Hazardous Substances (TRGS), where they exist.
