PLEASE NOTE: In March 2020, Safe Work Australia paused the release and public consultation for the workplace exposure standards (WES) review until further notice.

During this period of pause, you can continue to submit your comments for all current and previous releases via our dedicated inbox WESconsult@swa.gov.au. Please indicate the chemical/s that you are providing feedback for and whether your feedback is for yourself or on behalf of your organisation.

Information about the revised timeframes for completing the WES review will be communicated as soon as possible. Subscribe to the chemical exposure standards mailing list to say informed about the progress of the WES review.


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.

The draft evaluation reports and recommendations for the workplace exposure standards (WES) are provided for your information.

Each report includes:

  • a recommended WES value
  • information about the basis of the recommendation, and
  • a summary of the data relied upon to make the recommendation.

The recommended WES values are health-based recommendations made by expert consultants using the agreed methodology developed by Safe Work Australia, and have been independently peer reviewed.

We would like your feedback on these values, in particular, comments of a technical nature regarding:

  • the toxicological information and data that the value is based upon, and
  • the measurement and analysis information provided.

We are seeking comments of a technical nature on the draft evaluation reports and recommendations for the workplace exposure standards throughout the project.

The workplace exposure standards currently open for feedback are listed below.

Your feedback is important for Safe Work Australia Members in making recommendations to Work Health and Safety (WHS) Ministers about any changes to the workplace exposure standards. Changes to the workplace exposure standards only become mandatory once agreed by a majority of WHS Ministers and adopted in the WHS laws in the Commonwealth, states and territories.

Information about the revised timeframes will be communicated as soon as possible. Subscribe to the chemical exposure standards mailing list to say informed about the progress of the WES review.

Please contact wesconsult@swa.gov.au if you have any questions about this review.
