Document details
Regulation
Work Health and Safety Regulation 2025 (NSW) — High Risk Construction Work (s291; SWMS s299) and confined spaces (Part 4.3, entry permit), with the hydrogen sulphide workplace exposure standard
HRCW Category
High risk construction work — entry into a sewer, wet well or pump station is work carried out in a confined space and in or near a contaminated or flammable atmosphere (s291); a SWMS is required (s299) and a confined space entry permit under Part 4.3. Hydrogen sulphide is the dominant hazard: it forms in wastewater under septic conditions, is lethal at high concentration, and its odour fails as a warning because the sense of smell is rapidly deadened.
