ECETOC Targeted Risk Assessment Tool version 3 and associated workshop
3rd May 2012, Sheraton Brussels Airport Hotel

Since its launch in 2004, the ECETOC Targeted Risk Assessment Tool has proved to be an overwhelming success and the new version 3 will be released in the coming weeks along with updated user guides to reflect the changes. At the same time, ECHA has signalled its intent to update its Chesar CSA/ES tool. In this respect, updates to the worker and consumer tools are being developed in close co-operation with ECHA, who intend to incorporate the two human health components of the TRA into the new Chesar version 2. In addition to these two components, a spreadsheet implementation of EUSES is included in the integrated part of the TRA to facilitate environmental assessments. The integrated part of the TRA is also being updated. These new versions are currently being tested against the TRAv2 and other exposure models.

In order to explain TRAv3 and update users on the difference between TRAv2 and TRAv3, the European Centre for Ecotoxicology and Toxicology of Chemicals (ECETOC) is organising a workshop to be held in Brussels 3rd May 2012. There will be an attendance fee of Euro 200 per person. TRA Tool users who would like to attend this event should register their interest by completing the form at https://www.ecetoc.org/ecetoc-trav3-workshop-register-interest-in-attending. The workshop is likely to prove very popular so the available places will be issued on a first come “ first served basis. Further details on the TRA Tool can be found at https://www.ecetoc.org/tra.
