The guideline for the safe storage of packaged hazardous substances, the Hazardous Substances Publication Series 15 (PGS 15), was revised in 2025 and adopted by the Administrative Environmental Council.

The 2021 version of PGS 15 remains the prescribed version. Click here for the full announcement.
