Workplace Exposure Standards (WES) are airborne concentrations of certain chemicals that must not be exceeded. These limits help protect workers from harmful exposure.

You may be aware that, from 1 December 2026, Safe Work Australia (SWA) is replacing the current Workplace Exposure Standards (WES) list with the Workplace Exposure Limits (WEL) list.

While limits for most chemicals will remain unchanged, some may have a WEL introduced, removed, increased or reduced.

To understand the impact this may have on Victorian businesses, WorkSafe has engaged Nous Group (Nous) to undertake a regulatory impact statement (RIS) to estimate costs, benefits, and any unintended impacts.

We invite you to take part in a short online survey which should take only take 15 to 20 minutes to complete.

The survey asks about how you currently manage airborne contaminants and gives you a chance to share your feedback on the changes. Survey responses are anonymous.

The survey closes at 5pm on 17 August 2025.
