Silica Dust Regulations in Victoria: WorkSafe VIC Requirements for 2026
Victoria has a silica regulatory framework that differs meaningfully from every other Australian state — and silica dust monitoring under Victoria’s OHS framework has its own specific character — and in several respects, it sets a higher bar. WorkSafe Victoria operates under the Occupational Health and Safety Act 2004 (VIC) rather than the national WHS model legislation, meaning Victorian employers have a distinct compliance landscape to navigate.
Crucially, WorkSafe Victoria has adopted a recommended exposure target below the national WES — and if you’re in high-risk industries like construction, stone fabrication, or civil works, that difference matters.

Victoria’s Distinct Legislative Framework
Unlike Queensland, NSW, South Australia, Tasmania, and the ACT — which all operate under the model Work Health and Safety Act — Victoria retains its own standalone occupational health and safety legislation:
- Primary Act: Occupational Health and Safety Act 2004 (VIC)
- Regulations: Occupational Health and Safety Regulations 2017 (VIC)
- Regulator: WorkSafe Victoria
This means that while Victoria has broadly aligned with the national Chapter 8A crystalline silica framework in terms of outcomes, the specific regulatory instruments are different, and the guidance materials issued by WorkSafe Victoria have their own authority and character.
WorkSafe Victoria’s Lower Recommended Exposure Target
This is the detail most Victorian employers don’t know: while the national WES for respirable crystalline silica is 0.05 mg/m³ (8-hour TWA), WorkSafe Victoria recommends reducing worker exposures to below 0.02 mg/m³ as an 8-hour TWA.
This recommended target — at 40% of the national legal limit — reflects Victoria’s precautionary approach to RCS exposure. It’s not a legally binding requirement in the same way the WES is, but WorkSafe Victoria inspectors use it as a benchmark for assessing whether a PCBU is taking reasonably practicable steps to minimise exposure. In practice, if your monitoring results come back between 0.02 and 0.05 mg/m³, WorkSafe Victoria may still consider your controls inadequate.
For Victorian employers investing in silica controls, the appropriate design target is 0.02 mg/m³ — not 0.05 mg/m³.
High-Risk Crystalline Silica Work in Victoria
WorkSafe Victoria defines high-risk crystalline silica work as processing of a crystalline silica substance where the concentration of crystalline silica is equal to or greater than 1%, and the processing is likely to generate respirable crystalline silica dust. This covers:
- Dry cutting, grinding, drilling, or crushing concrete, masonry, stone, or silica-containing soil
- Processing engineered stone (now banned — see below)
- Sandblasting with silica-containing abrasives
- Tunnel boring, underground drilling and blasting in silica-bearing rock
Crystalline Silica Hazard Control Statement
Victorian employers who engage workers in high-risk crystalline silica work must prepare a crystalline silica hazard control statement before that work commences. This document must:
- Identify the specific high-risk tasks
- Document the control measures to be used for each task
- Specify the training requirements
- Describe the air and health monitoring arrangements
WorkSafe Victoria provides templates and guidance for completing the control statement. Inspectors check for this document on site visits to construction, quarrying, and demolition operations.
The Engineered Stone Ban in Victoria
From 1 July 2024, the manufacture, supply, processing, or installation of engineered stone benchtops, panels, and slabs is banned in Victoria. Engineered stone typically contains 90%+ crystalline silica — far higher than natural stone or concrete — and its processing generated some of the worst silicosis case clusters ever documented in Australia.
Stone fabrication workshops and kitchen/bathroom renovation businesses must not process engineered stone. WorkSafe Victoria conducts active compliance checks and has prosecuted businesses found processing engineered stone after the ban date.
Air Monitoring Requirements in Victoria
Victorian employers must conduct air monitoring for respirable crystalline silica in any workplace where there is a risk of exposure — which includes, for practical purposes, any site where concrete is being cut, ground, drilled, or demolished; any quarry or extractive industries operation; and any stone fabrication or tile manufacturing facility.
Monitoring must be conducted by a competent person with appropriate qualifications, training, and experience. WorkSafe Victoria guidance aligns with the national position: a certified occupational hygienist using a NATA-accredited laboratory is the accepted standard for defensible compliance monitoring.
Where monitoring results show exposures at or above 0.05 mg/m³, immediate action to improve controls is required. Where results fall between 0.02 and 0.05 mg/m³, WorkSafe Victoria expects progressive improvement in controls — simply meeting the national WES is not considered to represent best practice in Victoria.
Health Monitoring in Victoria
Employers responsible for high-risk crystalline silica work must arrange health monitoring for affected workers. Victoria’s health monitoring obligations require:
- A baseline assessment before commencement of high-risk work
- Periodic monitoring at intervals appropriate to exposure level — typically 12 months for ongoing significant risk
- Exit monitoring when workers cease high-risk work
- Health monitoring records kept for 40 years (Regulation 426Q under the national framework; Victoria applies equivalent retention periods under OHS Regulations)
Health monitoring records are the property of the worker and must be provided to them. Workers can also report health concerns directly to WorkSafe Victoria.
The December 2026 WEL in a Victorian Context
Victoria will align with the national WEL transition from December 2026 despite using its own legislative framework — WorkSafe Victoria will update its guidance and regulatory approach accordingly. For Victorian employers, the practical implication is to treat the current period as a final opportunity to establish baseline monitoring data under the current (slightly less prescriptive) framework.
Given WorkSafe Victoria’s already-recommended target of 0.02 mg/m³, employers in Victoria who have not yet achieved that level of control will face increasing regulatory scrutiny as the WEL transition approaches. [Internal link: Guide to the December 2026 WEL and how to prepare]
Frequently Asked Questions
Does Victoria use the WHS Act or its own OHS Act?
Victoria uses its own Occupational Health and Safety Act 2004 (VIC) — it has not adopted the national model WHS legislation. This means the specific regulations and guidance documents are Victorian-specific, even where the outcomes align with national standards.
What is the Victorian silica exposure target?
WorkSafe Victoria recommends reducing exposure to below 0.02 mg/m³ (8-hour TWA) — significantly below the national WES of 0.05 mg/m³. While the national limit remains the legal standard, WorkSafe Victoria treats 0.02 mg/m³ as the benchmark for reasonably practicable exposure reduction.
Is the crystalline silica hazard control statement mandatory in Victoria?
Yes. Victorian employers who engage workers in high-risk crystalline silica work must prepare a crystalline silica hazard control statement before work commences. This is a WorkSafe Victoria requirement and is checked by inspectors during site visits.
Can engineered stone be processed in Victoria?
No. The manufacture, supply, processing, and installation of engineered stone benchtops, panels, and slabs has been prohibited in Victoria since 1 July 2024.
