Overview
Safe Work Australia is evaluating the Workplace exposure standards for airborne contaminants to ensure they are based on the highest quality, contemporary evidence and supported by a rigorous scientific approach.
We would like your feedback on the draft evaluation reports and recommendations. In particular comments of a technical nature are sought about:
the toxicological information and data that the recommended workplace exposure standard is based upon, and
the measurement and analysis information provided.
For more information on other chemicals and their release dates, please see the release schedule.
Comments are open from Friday 11 October 2019 and will close on 8 November 2019.
