Module 20, The Extended SDS Understanding Exposure Scenarios
When hazardous substances are registered under REACH, it is necessary to make an assessment of risk for known uses of the substance and resulting mixtures to ensure that the uses for which are ‘suitable’ and risk can be managed. As part of this, exposure estimates resulting from scenarios of use are part of the chemical safety report (CSR) and the results of the CSR need to be communicated onwards to downstream users.
The SDS is the primary tool for communication and it is now necessary to identify these uses and describe the scenarios of use that have been considered when registering substances. This extended SDS is now required for registered hazardous substances and as they filter down the supply line, the findings will need to be taken into account by those preparing mixtures.
The exposure scenario (ES) for each of the uses identified in Section 1 of the SDS therefore needs to be part of the extended SDS and needs to be readable and relevant for the anticipated users (customers). The level of detail will reflect the degree of hazard and the knowledge of the recipient.
This course, delivered live, online over two consecutive mornings, aims to cover the principles of exposure assessment and the extended SDS, linking the technical concepts covered in Module 53 with regulatory and practical requirements. By responding to feedback to give more time to this topic, some of the data and scientific issues have been moved to Module 53 thus allowing Module 20 to include more in depth examination of example ES and a chance to prepare parts of the ES using CSRs or other sources of information.
Who Should Attend
The module is designed for those involved in chemical safety assessment and communication, within the context of product stewardship and with a particular focus on supply regulations, including REACH. Those receiving or preparing extended SDS will benefit.
Those attending should already understand the broad concepts of chemical supply legislation, including REACH, and also understand the science of data assessment including physico-chemical data, basic toxicology and basic ecotoxicity, as well as good working knowledge of the SDS. An understanding of the principles of DNELs and PNECs will also be of help.
Please note this Module is not suitable for newcomers to this area. It is recommended that delegates have previously attended Module 15 'Advanced Preparation of SDSs’ or Module 53 ‘Chemical Safety Assessment – The Science And Theory For Risk Characterisation’ or have similar experience in writing SDSs and in reading/understanding CSRs.
Benefits Of Attending?
Attendance on this module will ensure that you are up to date with the requirements for the production of Extended SDS. To ensure the most effective training with optimum involvement in participative exercises, there will be a limit of 14 on the number of students.
IOSH members are entitled to include this module in their continuing professional development records.

- Workplace exposure – industrial and professional
- Exposure to general public including secondary exposure through food and water
- Use of default data and guidance
- Overview of requirements document
- Practical review of template(s) including CSR templates
- Practical review of formatting and content
- Communication through supply chain
- Practical attempts at preparing ES and determining if level of exposure is acceptable
- Risk Management Measures
The training will be given by Mark Selby of Denehurst Chemical Safety Ltd. Mark had many years’ experience with a major test house before setting up his own business and runs the very successful CHCS modules on ecotoxicology, advanced SDS writing and Exposure Scenarios.
EU Exit Of The UK
The departure of the UK from the EU does not impact on the either the importance of the assessment of hazard and exposure, the SDS or the legal requirements. The formatting and content of the SDs is set by United Nations GHS and the UK will follow these requirements.
At the time of preparing these notes, it is unknown whether the UK will remain fully aligned and remain part of the REACH and CLP system, but even if reverting to UK-CHIP and UK-REACH, the principles will remain the same.
We will deliver this training using online training software, which we have used successfully for other CHCS training courses. You can use the software, free-of-charge on Windows, Macs, smartphones and tablets.
The sessions will run live and delegates can interact with the tutor and other delegates using their device microphone. The tutor will use a PowerPoint presentation, just as they would in face-to-face training. We will provide you with copies of the presentation and all other supporting documentation in advance of the training, by email.
“Engaging course leaders tried to make content more relevant to all attendees’ industries”
“Focuses on ‘useful’ info. Good overview of ESDS and also on mixture ES’s. Liked trying to translate CSR to ES’s for ESDS. Definitely have a better awareness as I head back to the office.”
“Good use of examples. Lots of discussion between presenter and participants”
“Good presenter, relaxed style, took questions easily and gave time to queries”
"Very easy to understand, explained all key concepts very well."
CHCS Training Courses are only available to CHCS members and members of our partner organisations listed below.
If you aren't a member of CHCS we'd be pleased to welcome you to the Society, and then you may register for training courses (and other CHCS member-only events). You can JOIN US by completing the form on this website.
Our online courses are priced at £275.00 (+VAT). However, we also offer a discount price of £250.00 (+VAT) for booking taken up to 6 weeks before the course date.
If you are a CHCS member, use your CHCS login details, then click on the "REGISTER" button shown on the right-hand-side of the screen. You will then be able to access either the Discount or Full-Price rate depending on the date.
You can pay online using your credit card, or have an invoice sent to you for payment by credit card or bank transfer. However, we only accept Credit Card payments for any registrations made within 5 weeks of the date of the course
