Model Code of Practice: Confined spaces

This model Code of Practice guides you on working in a confined space.

Use this Code of Practice if you:

• manage or control work in a confined space
• design, manufacture or supply plant or structures that include a confined space.

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.
