  1. Exposure Scenario Modifier Tool Workshop on REACH Exposure Scenarios Authority, ECHA and Industry Perspectives October 22-23, 2008 Dorte Rasmussen, DHI

  2. List of content • Background and content • Brief demonstration of IT-tool • Practical use of ’Descriptors of Use’ • Evaluation of ES-Modifier by others

  3. List of content Background and content Brief demonstration of IT-tool Practical use of ’Descriptors of Use’ Evaluation of ES-Modifier by others

  4. Focus group for tool:Formulators FORMULATORS own use uses by their customers

  5. Key use of ES-modifier 1. Harmonisation (OC’s and RMM’s) of ES’s received from different suppliers. 2. Scale the ES according to specific needs (eg. customer request) ES Substance 1 Duration: 2 hrs Ventilllation: No RMM: Mask ES Substance 2 Duration: 8 hrs Ventillation RMM: No ES Preparation Duration: ? Ventillation:? RMM: ? + = Duration: 8 hrs ES Preparation Duration: 4 hrs RMM: No Customer conditions

  6. Key OUTPUT: Calculation of RCR Risk Characterisation Ratio < 1 ≥ 1 Exposure HUMAN DNEL ES MODIFIER Exposure ENVIRONMENT PNEC Not Safe Safe

  7. Calculation of RCR Registrant data Specific Substance Specific use • Use in headlines • - LCS + usergroup • Descriptors of Use Substance Data - Eco- and Tox data - Phys-Chem data Use details(OC; RMM) Models DNEL PNEC Exposure (human) Exposure (env.) RCRhuman = ; RCRenv. = Exposure Exposure RCR < 1 PNEC DNEL SAFE USE

  8. ExposureAssessment • Default exposure models: • Ecetoc TRA • EUSES, with ERC’s (or industry specific release fractions) • COSHH-BAUA • Other models being included: • StoffenManager; RiskOfDerm

  9. Industry Headlines for a USE 1. Lifecycle stage Service Life (S) Manufacturing (M) Formulation (F) End use (U) Industry Consumer Professional 2. Usergroup Industry Professional Consumer 3. Descriptors of use (SU, PC, PROC, AC) = DoU

  10. Focus for ES-modifiertool • NOT • Company withriskassessmentexpertsorwhowillmake DU-CSR • Company participating in pan-europeanactivityregardingdevelopment of ES-concept under REACH • HOT • Formulating DU company/ Small tradingcompanyimporting from outside of EU • Basicknowledgehow to make SDS for preparations (max. 1-2 persons in HS&E department) • Noknowledgeaboutself-classfication • ES knowledgethroughnationalhelpdesks/trade organisations

  11. List of content Background and content Brief demonstration of IT-tool Practical use of ’Descriptors of Use’ Evaluation of ES-Modifier by others

  12. How to useES-modifier • Choose lifecycle stage (and user group) • Describe overall use according to DoU (Descriptors of Use) • Insert substance data (directly/plug-in)(Today ES-Modifier is substance based; future plans for preparations) • Choose models(Default models are Ecetoc TRA and EUSES) • Describe specific details of use • Make calculations and observe RCR results

  13. Action buttons Lifecycle stage + user group Substance Completeness indicator Descriptors of use (SU; PC; PROC; AC) Menu options Detailed input RCR Risk Charac. Ratio

  14. List of content Background and content Brief demonstration of IT-tool Practical use of ’Descriptors of Use’ Evaluation of ES-Modifier by others

  15. Practical use of ’Descriptors of use’ (DoU) • DoU is the main tool recommended in guidance for • the identification of use • and the headline in the ES • DoU is input parameter to exposure models • PROC => Occupational exposure calculation • PC/AC => Consumer exposure calculations • LCS+SU/PC/PROC/AC => ERC=>environmental exposure calculations • Conclusion from case studies in RIP 3.2 and various workshops: • DoU is difficult to use/not reproducible • More help is needed to find your way around in DoU

  16. SU (25) PC (41) PROC (25) AC (40) Possibility to filter DoUBranch or product specific Branch or product specific filter 1,025,000 possible combinations!

  22. Evaluation of ES-Modifier Functionality • DU Companies • DU sector groups (translation of e.g. PROC) Communication in supply chain (incl. exchange of substance data) • M/I Companies & sector groups (CEFIC) Discussion of responsibility • Authorities Validation of calculations • Experts

  23. Testing of ES-modifier • Three workshops have been held • 2 in Denmark and 1 in Holland • Participants • Industries, branch organisations - organised according to product chains

  24. Paints and adhesives Via a consultant Professional application Window Production of adhesives Raw material Distributor Brillestel Automatic application Production of paint Raw material Distributor Branch organisation Consumer

  25. Production of chemicals Chemicals trade Production of coatings, adhesives and sealants Industrial application of coatings, adhesives and sealants Professional application of chemicals Production of printing inks Industrial Printing Production of Cleaning products Cleaning services Industrial washing Production of Metal working fluids Production of Lubricants Production of packing materials Hospitals Authorities Manufacturer Downstream user, formulator Downstream user, other Importer Distributor Participants Industry sector Roles under REACH
