The national workplace exposure standard for respirable crystalline silica has been halved from an eight hour time-weighted average airborne concentration of 0.1 milligrams per cubic metre (mg/m3) to 0.05 mg/m3. This new workplace exposure standard takes effect in Queensland from 1 July 2020.
What it means for you
You must manage worker exposure to dust and meet your existing duties and obligations under Queensland work health and safety legislation. This means:
- using higher order controls (including elimination, engineering, isolation and substitution)
- air monitoring
- health monitoring
- training for workers
- appropriate respiratory protective equipment.
