From 17 November 2025, the workplace exposure standard (WES) for Aluminium (welding fumes) will be reduced from 5 mg/m³ to 1 mg/m³ (as an 8-hour time weighted average). This reduction brings the WES for aluminium welding fumes in line with the existing WES for welding fumes (not otherwise cl

Safe Work Australia is seeking feedback on a proposal to reduce the Aluminium (welding fumes) workplace exposure standard (WES) from 5mg/m³ to 1mg/m³. 

Safe Work Australia is consulting on the proposed workplace exposure limits (WEL) for 9 chemicals (benzene, chlorine, copper, formaldehyde, hydrogen cyanide, hydrogen sulphide, nitrogen dioxide respirable crystalline silica, titanium dioxide).

Safe Work Australia is seeking feedback on the impacts of proposed workplace exposure limits for 9 chemicals. The consultation aims to gather information on the economic, social and health impacts of the proposed exposure limit for each chemical.

Work health and safety (WHS) ministers have agreed to the new WEL list and a harmonised transition period ending on 30 November 2026. This change comes after extensive work and consultation to revise the Workplace exposure standards for airborne contaminants (WES).
