Safe Work Australia has updated 15 model Codes of Practice to support the transition from workplace exposure standards (WES) to workplace exposure limits (WEL). The updates reflect the change to WEL terminology and include links to new air monitoring guidance.
Australia is transitioning to the WEL list. From 1 December 2026, employers must ensure that no person at their workplace is exposed to an airborne contaminant at a level above the exposure limit in the WEL list. Until the WEL list comes into effect, employers must continue to comply with the current WES list.
To ensure our guidance remains up to date and supports workplaces in preparing for the transition, Safe Work Australia has published updated versions of the following model Codes of Practice:
- Abrasive blasting
- Confined spaces
- Demolition work
- Excavation work
- Healthcare and social assistance industry
- How to manage and control asbestos in the workplace
- How to manage work health and safety risks
- How to safely remove asbestos
- Labelling of workplace hazardous chemicals
- Managing noise and preventing hearing loss at work
- Managing risks of hazardous chemicals in the workplace
- Managing risks of respirable crystalline silica in the workplace
- Preparation of safety data sheets for hazardous chemicals
- Spray painting and powder coating
- Welding processes.
