Release 7 closed on Friday 6 December 2019. 

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 8 November 2019 and will close on 6 December 2019.
