Silica Dust Monitoring Services in Perth and Western Australia
OccHygiene provides silica dust monitoring and occupational hygiene services across Perth and Western Australia. With one of Australia’s largest and most diverse mining industries — gold, iron ore, lithium, nickel, copper — as well as a major construction and resources services sector, WA businesses face significant silica exposure risks and a regulatory environment that differs meaningfully from the rest of Australia.
Our team provides expert monitoring services calibrated to WA’s specific legislative framework, from metropolitan Perth construction projects to remote mine sites across the Goldfields, Pilbara, and Kimberley.
Western Australia’s Unique Regulatory Framework
Western Australia has not adopted the national model WHS laws. This makes WA’s regulatory environment distinct from every other state and territory in Australia.
For general industry (construction, manufacturing, services), WA operates under the Work Health and Safety Act 2020 (WA) and the Work Health and Safety (General) Regulations 2022 (WA). From 31 March 2022, WA effectively aligned with most of the national WHS framework, including provisions equivalent to Chapter 8A for crystalline silica dust. WorkSafe WA is the responsible regulator.
For mining and petroleum, WA operates under the Mines Safety and Inspection Act 1994 (WA) and the Mines Safety and Inspection Regulations 1995 (WA), enforced by the Department of Mines, Industry Regulation and Safety (DMIRS) — for full detail on WA mining and quarrying silica monitoring, including DMIRS vs WorkSafe WA jurisdiction, see our mining guide. This separate framework has its own monitoring and reporting requirements that differ from the WHS general regulations.
The engineered stone ban applies in WA from 1 July 2024, consistent with the rest of Australia.
The dual regulatory framework — WHS General for surface industry, Mines Safety for mining — means WA businesses must clearly identify which legislation applies to their operation before designing a monitoring program.
WA’s High-Exposure Industries
Western Australia’s economy is built on industries that generate significant crystalline silica exposure:
- Iron ore, gold, and lithium mining — WA is Australia’s dominant mining state. Underground hard rock mining and open-cut operations in the Pilbara and Goldfields create substantial dust exposure from drilling, blasting, crushing, and haulage.
- Mineral processing — Processing facilities for gold, iron ore, and lithium typically involve crushing, milling, and conveying of silica-rich ore bodies.
- Construction in Perth — The ongoing population growth in Perth sustains a large construction industry, with residential high-rise, infrastructure, and commercial development all requiring silica monitoring.
- Stonemasons — Granite and limestone fabrication remains an active industry in WA following the engineered stone ban. Natural stone work generates significant RCS.
- Resources services — Sandblasting, maintenance work on mining equipment, and fabrication in workshops supporting the resources sector.
What Our Monitoring Service Includes
OccHygiene’s WA silica monitoring service includes:
- Regulatory scoping — Confirming whether your operation falls under WHS General or Mines Safety regulations and which specific monitoring obligations apply
- On-site personal air sampling — Full-shift personal sampling with calibrated pumps in the worker’s breathing zone
- NATA-accredited laboratory analysis — Gravimetric and XRD analysis of RCS concentrations
- Monitoring report — Written compliance report aligned with WorkSafe WA or DMIRS requirements as applicable
- FIFO site logistics — For remote mining sites, we work with your site access, FIFO scheduling, and safety induction requirements

Frequently Asked Questions
Does WA Chapter 8A apply to Perth construction sites?
WA’s WHS General Regulations align with the national WHS framework including provisions equivalent to Chapter 8A. Perth construction companies have the same core monitoring obligations as builders in other states — monitoring where exposure could reasonably exceed 50% of the WES, health surveillance, and 30-year record retention for air monitoring results (Reg 426K); health monitoring records are kept for 40 years (Reg 426Q).
Who regulates silica on WA mine sites — WorkSafe WA or DMIRS?
DMIRS regulates mining operations under the Mines Safety and Inspection Act. WorkSafe WA regulates general industry operations, including surface facilities that are not part of a mine. Some sites may have elements of both — our scoping process confirms which framework applies.
Do you service FIFO and remote WA sites?
Yes. We work with FIFO rosters and remote site access requirements. Please contact us at least 3–4 weeks before your required sampling date for remote locations to allow for scheduling, inductions, and travel logistics.
