Unit 4.1 Exposure Scenarios

Unit 4.1 focuses on sovereign duties which were transferred to division 4 on the basis of chemical law regulations.

Therefore the unit's focus is on preparing and processing substance and product related dossiers under REACH- and Biocide regulations. In particular:

  • Description and assessment of workplace exposure
  • Proposal and evaluation of the effectiveness of technical, organisational and individual protections measures
  • Labelling of hazardous substances and mixtures as a part of risk communication

The unit participates in national and international committees which help fulfilling legal duties and responsibilities. For example:

  • Working groups of the German Committee on Hazardous Substances (AGS) for the development of technical rules for hazardous substances (TRGS)
  • Technical Meeting Biocides of the European Commission
  • OECD Task Force on Exposure Assessment
  • Partner Expert Groups of the European Chemicals Agency (ECHA) for the development of REACH guidance documents

Unit 4.1 closely cooperates in projects with other units of the Federal Institute for Occupational Safety and Health (BAuA) and with scientists of other institutes. These cooperation's as well as its own developments allow unit 4.1 to create the scientific and methodological basis required for fulfilling its sovereign duties. The main issues that are or have been processed in projects are:

  • Model development and validation to improve exposure estimates
  • Compiling control guidance sheets for the Easy-to-use workplace control scheme for hazardous substances (EMKG) for

    • Biocidal products
    • Hazardous substances
  • Investigations into exposure estimates and risk management measures for biocidal products, e.g.:

    • Concentrates
    • Insecticides
