Model Code of Practice: Labelling of workplace hazardous chemicals

This model Code of Practice guides you on how to correctly label hazardous chemicals used in the workplace.

Use this Code of Practice if you make, import, supply or use hazardous chemicals.

To support the transition from workplace exposure standards (WES) to workplace exposure limits (WEL), this model Code of Practice has been amended to reflect the change in terminology to WEL. The WEL comes into effect from 1 December 2026.

Check with your regulator to find out if this Code of Practice has legal effect in your jurisdiction.
