Concrete grinding, scarifying and polishing operations generate respirable crystalline silica (RCS) dust at concentrations that routinely exceed the workplace exposure standard of 0.05 mg/mΒ³ (8-hour TWA) by orders of magnitude when performed dry without engineering controls. Cured concrete typically contains 20β40% crystalline silica by mass, and mechanical abrasion fractures quartz crystals into the sub-4 micron respirable fraction that penetrates deep into alveolar tissue, causing silicosis, lung cancer, COPD, and autoimmune disease. This SWMS addresses surface preparation grinding, diamond polishing, scarifying, and edge grinding using planetary grinders, hand-held angle grinders, and walk-behind machines.
Under the model Work Health and Safety Act 2011 and WHS Regulation 2025, a Person Conducting a Business or Undertaking (PCBU) must prepare a SWMS before commencing High Risk Construction Work involving crystalline silica dust (HRCW Category 19, Regulation 291). Regulation 49 requires elimination or minimisation of airborne contaminants so far as is reasonably practicable, and Regulation 50 mandates that the workplace exposure standard for RCS is not exceeded. The 2024 amendments following the engineered stone prohibition strengthened silica controls across all silica-containing materials including concrete.
This SWMS satisfies Regulation 299 SWMS content requirements and incorporates the Safe Work Australia Code of Practice: Managing the risks of respirable crystalline silica from engineered stone in the workplace (2024) and the Working with silica and silica containing products COP. It documents H-class vacuum extraction, wet suppression, respiratory protection programmes meeting AS/NZS 1715:2009, air monitoring under Regulation 50, and health monitoring obligations under Regulations 368β378.

High-Risk Construction Work triggered
Grinding, scarifying, and polishing of cured concrete mechanically fractures quartz crystals into the respirable fraction (<4 Β΅m aerodynamic diameter). Concrete contains 20β40% crystalline silica by mass, and these tasks are explicitly identified in the SWA Silica COP as RCS-generating activities. HRCW Category 19 was introduced through the 2024 model WHS Regulation amendments and applies regardless of dust control measures used.
Because this work is HRCW under Regulation 291, a SWMS must be prepared before work commences (Reg 299), kept available for inspection (Reg 301), reviewed if controls are revised or after an incident (Reg 302), and the work must be stopped if not conducted in accordance with the SWMS (Reg 303). Failure to prepare a compliant SWMS attracts penalties up to $7,200 (individual) or $36,000 (body corporate) per offence under the model Regulations, and may constitute evidence of failure to discharge the primary duty under s.19 of the WHS Act with Category 1β3 offence exposure.

Worked example
Diamond Floors Pty Ltd is engaged to grind and polish 1,800 mΒ² of concrete in a new Sydney distribution centre over 10 shifts. Before mobilisation, the site supervisor downloads this SWMS, populates the company details, project address, and assigns the planetary grinder operator (Jamal) and edge grinder operator (Priya). At the pre-start, Jamal verifies the Husqvarna PG820 is connected to the H-class Pullman 2400W vacuum with green airflow indicator, and Priya confirms her PAPR battery and HE filter cartridge meet AS/NZS 1716. Both operators have current quantitative fit-test certificates and have completed silica awareness training recorded in the SWMS appendix. On day three, the principal contractor's WHS advisor conducts an inspection and requests the SWMS, air monitoring results, and health monitoring records. Diamond Floors produces the document showing personal sampling results from day one (Jamal 0.018 mg/mΒ³, Priya 0.024 mg/mΒ³ β both below WES with PAPR providing additional margin), the signed daily sign-on register, and Priya's pre-employment HRCT report. The advisor accepts the controls as adequate. When Priya later moves to edge grinding in a stairwell with reduced ventilation, the SWMS review trigger under Reg 302 is invoked β the supervisor amends controls to add portable HEPA air scrubber and re-briefs the team, documenting the change before recommencement.

Frequently asked questions
Does this SWMS cover both wet and dry concrete grinding methods?
Yes. The SWMS prioritises wet suppression as the preferred control under the hierarchy but provides full controls for dry grinding using H-class vacuum extraction where wet methods are not practicable (e.g. polished concrete final passes, electrical equipment proximity, sloped surfaces). Both methods include the same RPE, air monitoring, and health monitoring requirements.
Is air monitoring legally required for every concrete grinding job?
Under Regulation 50, air monitoring is required when there is uncertainty about whether the workplace exposure standard is exceeded, or whether monitoring is necessary to determine risk to health. For concrete grinding β a known high-exposure task β most regulators expect baseline personal monitoring to validate controls, with periodic repeat monitoring (typically annually or when methods change). The SWMS includes a monitoring schedule template.
Who needs health monitoring and how often?
Any worker who is at significant risk of exposure to RCS above the WES, or whose work is reasonably likely to result in adverse health effects, requires health monitoring under Regulation 368. For concrete grinders this typically means pre-employment baseline (HRCT, spirometry, occupational history, respiratory questionnaire) and biennial review by a registered medical practitioner with experience in occupational lung disease. Records must be retained for 30 years.
Can a P2 disposable mask be used for concrete grinding?
A P2 half-face respirator (protection factor 10) is only adequate for short-duration, well-controlled tasks where measured exposures with engineering controls in place remain below 0.5 mg/mΒ³ (10Γ WES). For most production grinding, edge work, or any dry grinding, a PAPR (PF 50) or full-face P3 is required. Selection must follow AS/NZS 1715 and be based on actual measured exposures β the SWMS includes a selection matrix.
How does this SWMS differ from a generic concrete works SWMS?
Generic concrete SWMS typically address formwork, pouring, and finishing hazards but lack the specific RCS controls, monitoring obligations, RPE programme detail, and health surveillance required under HRCW Category 19. This SWMS is purpose-built for grinding/polishing operations and references the SWA Silica COP, AS/NZS 1715/1716, and AS/NZS 60335.2.69 with operational detail that satisfies regulator expectations following the 2024 silica reforms.
Is this SWMS compliant in all Australian states and territories?
Yes. The document is built on the model WHS framework adopted by NSW, QLD, SA, TAS, ACT, NT, and the Commonwealth. Victoria operates under the OHS Act 2004 and OHS Regulations 2017 and Western Australia under WHS Act 2020 β both have equivalent silica and construction provisions. The included state legislation schedule maps the duties to each jurisdiction's specific section numbers and regulatory body (SafeWork NSW, WorkSafe Vic, WorkSafe WA, etc.).
