Two stories travel together in WHS channels: everything changes on 1 December 2026, and RCS halves to 0.025. For tunnelling dust programs, both need a clear correction. WES becomes WEL and new entries appear, including DPM as respirable elemental carbon. But the RCS value remains 0.05 mg/m³ respirable on 1 December 2026. Do not write...
Tunnelling puts people and diesel plant in the same confined air volume for long shifts.

The Heavy Vehicle National Law just had its biggest shake-up in over a decade, and it landed on 1 August 2026. If you run a transport or logistics business in NSW, Victoria, Queensland, South Australia, Tasmania, or the ACT, the rules you’ve been operating under have changed, and a documented Safety Management System is no...
