15 model Codes of Practice updated ahead of exposure limit changes
12 Nov 2026•BlueSafe Team•Source: Safe Work Australia
Safe Work Australia has revised 15 model Codes of Practice to help workplaces prepare for the move from workplace exposure standards (WES) to workplace exposure limits (WEL). The WEL list takes effect on 1 December 2026.
The revisions introduce WEL terminology and add links to new guidance on air monitoring.
From 1 December 2026, employers must ensure nobody at their workplace is exposed to an airborne contaminant above the exposure limit specified in the WEL list.
Employers must continue to meet the requirements of the current WES list until the WEL list takes effect.
Safe Work Australia’s airborne contaminants hub provides resources and guidance on WHS duties and preparing for the transition.
