Chromium trioxide
NOTE TO THE READER
In 2012, a group of more than 150 companies came together to form the Chromium Trioxide REACH
Authorization Consortium (CTAC). The sole purpose of this consortium is the joint development of
the documentation required to submit REACH authorisations for several Chromium Trioxide uses.
All the companies included in this application are SMEs (small enterprises) that were founding
members of the CTAC, actively participating and providing data for the development of the file
relating to the use of chromium trioxide in hard chrome plating - along with 90 other companies
specifically interested in this use-.
As a result of the work carried out under the CTAC, this Chemical Safety Report (CSR) was
completed in April 2015. It includes a Generic Exposure Scenario (GES) with a number of conditions
of use and risk management measures that lead to an exposure estimation directly associated with a
Socio-economic Analysis (SEA) which shows that the benefits of continuing to use the substance
greatly outweigh the non-use scenario.
In order to demonstrate that the conditions of use developed in applicants' facilities are carried out
within the limits and boundaries set by the Generic Exposure Scenario, and that the exposure remains
at the lowest threshold possible through the use of best industry practices, this CSR has been
completed and refined with specific information for each installation for which authorisation is
sought.
