ENES - the Exchange Network on Exposure Scenarios - is a collaborative network which was set up in 2011 and which brings together ECHA, Competent Authorities from the Member States and several industry organisations, such as DUCC, Cefic, Concawe and Eurometaux.
The aim of ENES is to identify good practices for preparing and implementing exposure scenarios, in order to develop an effective communication exchange between supply chain actors on the safe use of chemiclas, therefore improving the protection of human health and the environment.
All involved parties come together at ENES related events to share knowledge, techniques and approaches on what concerns REACH exposure scenarios.
Information on the developments and on the events organised in the context of ENES can be found on the ECHA dedicated website.

ECHA has published the “CSR/ES Roadmap” in July 2013.
DUCC has contributed to the drafting and is involved in the Roadmap implementation, leading and/or contributing to many of its actions.
The main objective of the activities under this Roadmap is to improve the quality of information communicated in the exposure scenarios included in the Chemical Safety Reports and in the extended Safety Data Sheets. The actions in the Roadmap are divided in five areas:
This Roadmap is the result of a collaborative effort of ECHA, eight Member States’ Competent Authorities, Cefic, Concawe and DUCC.
A Charter has also been published which is open for signature of other stakeholders, such as sector organisations and authorities.
DUCC welcomes the roadmap and intends to actively contribute to its implementation. All actors, from industry and authorities alike, will need to work together to achieve the roadmap objectives and, ultimately, safer use of chemicals through their entire life cycle.

ECHA has created a library that provides all the available use maps and exposure assessment inputs (SWEDs, SpERCs and SCEDs) prepared by sector organisations representing downstream users, as part of the CSR/ES Roadmap.
This library is frequently updated, as new information becomes available. Registrants are therefore encouraged to consult this website regularly.
On the 6 October, at the General Assembly of Cefic in Florence, a joint statement was signed by ECHA, Cefic and DUCC, which shows the commitment of these three institutions to enhancing communication in the supply chain on the use of chemicals.
The CSR/ES Roadmap Coordination Group has recognised that improving use maps is a basis for performing good quality chemical safety assessments (CSAs) and, therefore, some actions in the Roadmap are dedicated to this topic and other related topics. More concretely, since early 2014 a series of related actions 2.1., 2.2., 2.3., 2.4. and 2.5. have been merged to tackle this topic. Moreover, it has been presented and discussed during several Exchange Network on Exposure Scenarios (ENES) events.
For around two years there was a dedicated working group and some calls for testers have been launched. Thanks to the participation of many stakeholders it has been posisble to agree on a new template - the "improved" use maps template - in early 2016. A guidance document has also been issued. Ideally, all the industry associations who have developed use maps in the past will update them into this new template and, moreover, new industry associations who haven't developed any use maps so far will engage in this initiative.
More information about the "use maps package" can be found on the dedicated ECHA website.
For more information on supply chain communication and use identification visit the following websites:
REACH gives downstream users the right to communicate their uses, together with specific conditions of use, to their suppliers with a view to make their use an identified use covered in the registration dossier. Distributors should pass on the information in the supply chain.
However, REACH does not prescribe any particular format for exchanging information on uses in the supply chain. Standard processes and tools are necessary to facilitate use communication, exposure scenario development and guarantee that registration dossiers adequately address all (or as many as possible) uses of substances.
To avoid that multiple and inconsistent formats be used by different companies or different DU industry sectors for their use inventories and reporting, DUCC developed in 2009 the UseR (Use Reporting) template to assist downstream users in informing their suppliers on their uses and conditions of use, thereby assisting on the preparation of registration dossiers.
This template is a tool that DU associations and their members can use for mapping and reporting uses for their respective sectors. It has deliberately been kept simple. It contains two tables:
Each Downstream User Association is responsible for filling and updating the use information for its sector and post the corresponding tables or inventories on their respective website, so that they are readily accessible by registrants.
Based on experience gained with 2010 registrations, the UseR template has been revised in February 2012. A column has been added to the operational conditions table, which allows each company to indicate the concentration of the substance in the mixture, if considered relevant. This is a parameter that may be important when registrants are performing their chemical safety assessment, in the sense that it allows a more adequate estimation of the exposure.
In preparation of the 2013 registrations, DUCC, Cefic and Fecc have agreed to advise their members to follow the "top-down approach" regarding the use communication. For more information please see the Letter and the Fact Sheet on use communication.

The SpERCs are the Specific Environmental Release Categories. The SpERCs factsheets provide information on the operational conditions (OCs) and risk management measures (RMMs) and on the corresponding release factors to water, air, soil and waste in a downstream user sector.
The SpERCs can be used by registrants to perform the environmental exposure assessment part of their REACH chemical safety assessment.
In July 2016, a new SpERC Factsheet has been published, including explanatory notes. This new factsheet results from the discussions between industry, Member States and ECHA as part of Action 2.4. of the CSR/ES Roadmap.
For more information on the SpERCs please also visit the ECHA website dedicated to the Use Maps package.

The SCEDs are the Specific Consumer Exposure Determinants. The SCEDs are being developed by some sector organisations to transparently document the way that their products are commonly used by consumers.
The SCEDs factsheets will document typical conditions of use of consumer products, expressed in a form that can be fed into the commonly applied exposure assessment tools.
This project was initiated in 2012 and later has been integrated in the "CSR/ES Roadmap", as action 2.5..
Currently, two sector associations have already published their SCEDs: Concawe and A.I.S.E./FEA. Other sectors (CEPE and FEICA) are working to make their SCEDs publicly available around Summer 2016.
Discussions within DUCC had already been initiated, but following the publication of the CSR/ES Roadmap in July 2013, DUCC has committed to lead the Roadmap actions 4.4.B and 5.1 on Downstream User sector approaches to generating safe use information for mixtures, i.e. the “bottom-up” approaches which are based on the sector use maps.
The general principles of this approach had already been incorporated in the ECHA Guidance for Downstream Users since 2013 but further discussion on the details and templates was needed. Therefore, DUCC has initiated a comprehensive discussion on a template to present safe use advice information for mixtures, in an easy to read format for the end-users – such template has been named SUMI, Safe Use of Mixtures Information.
The SUMIs are based on the information coming from the SWEDs, the Sector-specific Worker Exposure Descriptions, which are the focus of action 2.3.A of the CSR/ES Roadmap.
In May 2015 the SUMI template has been presented at ENES 8 – click here for more information.
In December 2015 DUCC published an explanatory document on “Sector Specific approaches towards developing and communicating information for the safe use of mixtures” which includes also the SUMI template.
A template for the SWEDs has been published in early 2016. The SWEDs will contain information on operational conditions and risk management measures for activities carried out by workers.
In 2016 and 2017 the DUCC membershave been busy with the publication of their sector-specific SUMIs and respective SWEDs, as well as with the creation of the corresponding Chesar files.
The SWED/SUMI approach in brief:
They define conditions of safe use of mixtures for workers (industrial and professional end-users)
The SWEDs can be used by the registrants as input information to perform the Chemical Safety Assessment (both in a new registration in 2018 or in an update of a registration dossier)
The SUMIs are a communication format for downstream communication. The formulator will attach it to the Safety Data Sheet of the mixture, when appropriate

The ESCom standard for the exchange of exposure scenario (ES) data between IT systems has been developed to enable consistent and harmonised communication of ES information throughout the supply chain. ESCom is a package consisting of:
The ESCom package is one action of the CSR/ES Roadmap – action area 3.

Upon receiving an ext-SDS, i.e. a Safety Data Sheet with a REACH registration number and at least one Exposure Scenario attached, the downstream user needs to check if his uses and conditions of use, as well as the intended uses and the uses that he has been made aware of, are covered by the supplier’s exposure scenario(s).
In order to do so, the downstream user needs to check not only the titles of the Exposure Scenarios and Use Descriptors, but also the Operational Conditions (OC) and Risk Management Measures (RMM).
There are several options for the downstream user when his use is not covered, one of them being to notify ECHA and to complete a DU CSA/CSR.
The following documents provide more details on this topic:
Related to this topic, ECHA has published a report explaining how the information in the downstream user reports is being used - this was the objective of Action 4.6 of the CSR/ES Roadmap, to increase the understanding of how authorities can use downstream user reports.
Under REACH, Downstream Users (DU) should not place on the market substances as such, in mixtures or in articles if they have not been duly registered by the relevant manufacturers or importers (unless they are specifically exempted from registration).
For many substances, a chemical safety report (CSR) will have to be submitted as part of the registration dossier: exposure scenarios (ES) covering the various identified uses will have to be generated and communicated to downstream users via safety data sheets (SDS), as applicable.
Before REACH, manufacturers, importers, downstream users and distributors were already required to compile and supply a Safety Data Sheet at the first delivery of a dangerous substance or mixture (previously named "preparation"). REACH took over that existing duty in its Article 31 (requirements for the Safety Data Sheets) and in Annex II (guide to the compilation of Safety Data Sheets).
Safety data sheets contain information on the hazards of the substance or the mixture, as well as information on the recommended risk management measures to adequately control any risks to health and environment. In addition, for all those substances for which a chemical safety assessment (CSA) is required and that are classified as hazardous, the relevant exposure scenarios shall be annexed to the Safety Data Sheet.
This obligation to annex exposure scenarios to the SDS has to be fulfilled by:

Under REACH, for many substances a chemical safety assessment (CSA) will have to be performed and a chemical safety report (CSR) will have to be submitted as part of the registration dossier.
There are some existing tools which can help on this task:
