From 1 December 2026, new workplace exposure limits will apply to airborne contaminants including dust, fumes, gases, vapours and mists.
The changes apply across WA workplaces where workers may be exposed, with industries including mining, construction, manufacturing and agriculture expected to be particularly affected.
WorkSafe WA is encouraging businesses to prepare now by reviewing potential exposures, existing risk assessments and control measures to ensure they remain appropriate under the updated limits.
If airborne contaminants are present in your workplace, now is the time to understand what the changes mean for your business.
