Document details
Regulation
Work Health and Safety Regulation 2025 (NSW) — High Risk Construction Work (s291; SWMS s299), confined spaces (Part 4.3, entry permit) and hazardous chemicals / gas under pressure
HRCW Category
High risk construction work — inerting and purging is carried out on and in confined spaces and creates a contaminated, oxygen-deficient atmosphere (s291); a SWMS is required (s299) and a confined space entry permit under Part 4.3. An inert atmosphere is the most deceptive hazard in confined space work: nitrogen and other inert gases displace oxygen and give the body no warning, so a worker who enters or is engulfed collapses within seconds, and an unprotected rescuer dies the same way.
