To support compliant use of the five authorised ADCR chromate substances, ADCR has developed several supporting documents.
On this page you will find Exposure Scenarios, several flow charts, and later in 2025, additional guidance documents will be published.
ADCR has developed the Exposure Scenarios to be placed in annex of the Safety Data Sheet (SDS) for Chromium Trioxide (CT), Dichromium Tris(Chromate) (DtC), Potassium Dichromate (PD), Sodium Chromate (SC) and Sodium Dichromate (SD).
Depending on the authorised use, Application Holders and Downstream Users will have to identify the appropriate Exposure Scenarios (ES) to be annexed to their SDS, delete the non-relevant uses in the overview table (page 3) and the corresponding ES in the core document. The introductory section (pages 1 and 2) should be kept as an introduction of the annex.
Currently, only the English versions are available but translations into several other EU languages are being prepared and will be published (likely in April 2025)

ADCR has produced two recordings and published them on YouTube: ADCR Consortium - YouTube.
Overview of obligations in EC implementing Decisions for ADCR Authorisations and ADCR - How to execute at a site | Ensure compliance with granted ADCR Authorisations
The slides used for the overview recording is provided as a pdf:
Overview of obligations in EC implementing decisions for ADCR Authorisations
The overview recording, provides information on the ADCR Authorisations, and walks through the implementing decisions in high level detail.
The second recording, presents two guidance flow charts for ensuring compliance with the required conditions of the ADCR EU REACH Authorisations and the guidance flow chart on feasibility studies (see below)
ADCR has developed a guidance flow chart to support compliance with the conditions found in the implementing decisions. ADCR T1 EU Implementing conditions guidance flow charts 11032025.
A flow chart is also developed to give guidance on the feasibility studies, where required from the implementing decisions. ADCR T1 EU feasibility study guidance flow charts 21022025.
To support downstream users ADCR has developed flow charts to support identification of the relevant REACH Authorisation Number for each use and substances.

The UK Health and Safety Executive have useful information and advice on how to Commission your local exhaust ventilation (LEV) system, presented in their topics page on Local exhaust ventilation (LEV): workplace fume and dust extraction. There is much useful information presented, which is to a large extent also applicable for an EU site.
The ADCR Consortium developed an ADCR FAQ Document (pdf version 26 March 2025, replaces previous version of 16 August 2024) answering many questions related to the current applications and supply chain questions.
In July 2024 ADCR provided a Factual Communication providing concise information on the submitted ADCR dossiers. As Authorising Decisions have now been provided, the Factual Communication is not as relevant anymore.
