Exposure Scenarios and the Chemical Safety Report
Course coordinator:Alex PaulPrincipal: Chemical Regulatory Services, Yordas Group, UK
Lead Trainer: Neil Hunt (Senior Regulatory Scientist)Dr Neil Hunt leads the Yordas chemical exposure team and has authored Chemical Safety Reports for a number of substances as part of REACH registration, including UVCB, inorganic and highly toxic substances. He also provides training to both registrants and downstream users in how to both write and implement exposure scenarios and extended safety data sheets.Having completed a Masters Degree in Environmental Management and Consultancy at Lancaster University, he has worked for Yordas Group (ex-The REACH Centre) for over 8 years. In addition to exposure assessments, he specializes in the areas of chemical characterization and REACH Authorisation.Senior Regulatory Scientist: Neil HuntSenior Regulatory Specialist, Yordas Group, UK
- General Introduction to Risk Assessment and how it can be applied to the use of substances
- How hazard assessment of a substance is done under REACH
- Exposure Scenarios - How the life cycle of a substance is described under REACH using Exposure Scenarios and Contributing Scenarios. This section will introduce the Use Descriptor system and the tools used to calculate exposure.
- Exercise 1- Using Use Descriptors to define your use of a substance
- Risk Management - How risk from exposure to a substance can be calculated and a conclusion reached whether risk is acceptable or not. Which risk management measures are available to a registrant or downstream user to reduce risk?
- Discussion of the formats of Extended Safety Data Sheets and Exposure Scenarios that a recipient may receive.
- Obligations under REACH of Producers of Extended Safety Data Sheets
Proving compliance with Exposure Scenarios
- The obligations of recipients of an Extended Safety Data Sheet. Are all your uses covered and what to do if they are not?
- Exercise 2 - Assessing whether your use is covered by a supplied eSDS
- If uses are covered how can compliance with Exposure Scenarios be proven?
- Use of measurement, scaling and exposure modelling tools to prove compliance
- Exercise 3: Using scaling to prove compliance
Exposure Scenarios for substances be applied to mixtures?
- How can the techniques used within Exposure Scenarios for substances be applied to mixtures? This section will look at the output of the ENES project, covering both the “top-down” and “bottom-up” approaches proposed. The concepts of SUMIs, SWEDs and Lead Component will be introduced.
- Exercise 4: Identifying Lead Components in a mixture and the information that should be included in a mixture Exposure Scenario
- Conclusions and final remarks
Event wrap up and final Q&A
