PLEASE NOTE: In March 2020, Safe Work Australia paused the release and public consultation for the workplace exposure standards (WES) review until further notice. Public feedback resumed on 1 February 2021 with Release 15: paraffin wax to zirconium compounds. This release will be open on our consultation platform, Engage until 30 July 2021. Please indicate the chemical/s that you are providing feedback for and whether your feedback is for yourself or on behalf of your organisation. 

The public feedback process for releases 2 to 14 closes on 1 February 2021. For the latest information please continue to visit Engage.
