Silica Dust Regulations in Tasmania: Compliance Guide for 2026
Tasmania adopted the national crystalline silica regulations — and silica dust monitoring obligations in Tasmania are fully enforced under Chapter 8A through the Work Health and Safety (Crystalline Silica Substances) Regulations 2024, notified in the Tasmanian Gazette on 27 August 2024 and taking effect 1 September 2024. For Tasmanian employers processing concrete, stone, masonry, or any silica-bearing material, these regulations bring new and significant obligations.

Legislative Framework in Tasmania
- Primary Act: Work Health and Safety Act 2012 (Tas)
- Regulations: Work Health and Safety Regulations 2012 (Tas), as amended by the crystalline silica substances regulations (2024)
- Regulator: WorkSafe Tasmania (part of the Department of Justice)
Tasmania’s framework mirrors the national model WHS legislation and has implemented Chapter 8A in the same form as Queensland, NSW, South Australia, and the ACT.
Chapter 8A Obligations in Tasmania
All Tasmanian PCBUs whose workers process crystalline silica substances (any material containing ≥1% crystalline silica) must now:
Assess and classify the work: Determine whether processing is high-risk. Hard-rock cutting, dry grinding, drilling into concrete, and masonry demolition are typically high-risk unless controls can demonstrably reduce exposures below action levels.
Implement a silica risk control plan: If work is classified high-risk, a written risk control plan must be prepared before work begins and kept up to date. The plan must document controls, monitoring arrangements, and training status.
Provide accredited training: Workers and supervisors engaged in high-risk silica processing must complete nationally recognised crystalline silica training. Tasmania has embraced this requirement as part of a broader push to address the state’s occupational disease burden.
Conduct air monitoring: Where there is uncertainty about whether the WES of 0.05 mg/m³ is being met, monitoring must be conducted by a competent person using a NATA-accredited laboratory. Results must be retained for 30 years.
Arrange health monitoring: Workers in ongoing high-risk roles must receive baseline health checks, periodic monitoring, and exit assessments at the employer’s cost.
Engineered Stone Ban
Tasmania’s ban on processing, manufacturing, supplying, or installing engineered stone benchtops, panels, and slabs took effect 1 July 2024, in line with the national approach.
Tasmania’s Industry Context
Tasmania’s silica risk profile is shaped by its dominant industries:
Construction and civil: Significant residential and infrastructure construction, particularly in the Greater Hobart area, creates ongoing concrete cutting and grinding exposure risks. Many small and medium builders in Tasmania are still establishing their Chapter 8A compliance.
Mining and quarrying: Tasmania has a substantial mining heritage — copper, zinc, lead, gold — and active quarrying operations providing construction materials. Underground mining operations carry heightened silica risk from drill-and-blast activities in silica-bearing rock.
Dolerite and sandstone working: Tasmania’s distinctive geology — abundant dolerite, sandstone, and quartzite — means that stonemasons, landscapers, and civil earthworks contractors face silica risks from working with materials that are very high in crystalline silica content.
December 2026: What Tasmanian Employers Must Do Now
The December 2026 WEL transition is approaching. Tasmanian employers should use the time remaining to conduct baseline air monitoring, confirm the effectiveness of existing controls, and put in place the documentation required under Chapter 8A. WorkSafe Tasmania has signalled that silica compliance will be a continued enforcement priority. [Internal link: Full guide to the December 2026 WEL transition]
Frequently Asked Questions
Does Tasmania use the national WHS Act?
Tasmania enacted its own Work Health and Safety Act 2012 (Tas) modelled closely on the national WHS model laws. The crystalline silica substances regulations adopted in August 2024 follow the national Chapter 8A framework.
Who regulates silica in Tasmanian mines?
WorkSafe Tasmania regulates most Tasmanian mines under the WHS Act. Specific mining safety matters may also be subject to the Workplace Health and Safety (Mines) Regulations.
Is the silica exposure limit different in Tasmania?
No. The national WES of 0.05 mg/m³ (8-hour TWA) applies in Tasmania. There is no Tasmania-specific variation to the national limit.
