60 Modular Exposure Models for OSH Risk Assessment in Chemical Safety – MEMORA

Abstract Introduction European chemicals legislation aims to provide the best possible protection for workers when handling chemicals. The regulation of substances, mixtures and products is based on reliable risk assessments. This includes assessing workplace exposure to chemicals, which requires information on, e.g., the route of exposure (dermal/inhalation) and the level and duration of exposure. Methodology Exposure assessment requires the use of models, as workplace exposure data are often not available. The practical application of models as well as validation and comparative studies in recent years have led to the conclusion that further development of models is necessary. Key factors include a more user-friendly, transparent design of the tools and the addition of a dermal exposure module. Experiences from other BAuA projects (e.g., ETEAM and SysDEA) provide important insights for model-improvement. The MEMORA-project aims to develop a user-friendly toolbox covering both inhalation and dermal exposure assessment. Existing BAuA tools are examined and improved based on scientific findings, additional models will be included and a systematic tiered approach will be developed. Results/Conclusion During the workshop, 4 speakers will present the ongoing developments of different projects within the MEMORA-project-bundle. The aim is to develop solutions to questions that have arisen during the projects. Therefore, the presenters are interested in feedback from the participants to allow for possible adjustments to the chosen approaches. The workshop is intended to support the development of the toolbox in order to tailor it as much as possible to the needs of its users (practitioners, regulators, academics, etc.).
