The Health and Safety at Work (Hazardous Substances - Modified Application of Controlled Substance Licence Requirements for Specified Class 1 Substances) Safe Work Instrument 2023 and the 2025 amendment specify licensing requirements for certain class 1 (explosive) hazardous substances.
Principal SWI
Amendment SWI
Consolidated safe work instruments
When a principal SWI is amended, WorkSafe also publishes a consolidated SWI. This makes it easy to see all the requirements set by a SWI, including any amendments, in a single place.
Although a consolidated SWI is a useful summary, it is not the official version of the SWI.
Key points
- A consolidated SWI combines the principal (original) SWI with any later amendments.
- Unlike the principal SWI and the amended SWI, which are both a form of legislation, a consolidated SWI is for reference only and has no official status.
- The consolidated SWI is based on the law at the time that the SWI was consolidated.
