Abrasive blasting is one of the highest-risk surface preparation activities in Australian workplaces, exposing operators and bystanders to respirable crystalline silica (RCS), toxic fume from coatings such as lead, chromate or isocyanate-based paints, high-velocity media impact, and confined space atmospheres inside blast cabinets, tanks and pressure vessels. This Safe Work Method Statement covers both open-air and enclosed abrasive blasting operations, including media selection (garnet, slag, glass bead, steel grit), blast pot and deadman valve management, nozzle wear inspection, supplied-air respirator (Type CE) fitting, WES-compliant dust suppression, and the safe handling and disposal of spent media which is classified as a regulated waste under most state EPA frameworks.
Under the Model Work Health and Safety Act 2011 and WHS Regulation 2025, abrasive blasting is captured by Part 7.1 (Hazardous Chemicals) and Part 4.5 (Confined Spaces), and where conducted on a construction site is High Risk Construction Work under Regulation 291. The Safe Work Australia Code of Practice: Abrasive Blasting (2021) is an approved code under section 274 of the WHS Act and is admissible in proceedings as evidence of what is reasonably practicable. The Workplace Exposure Standard for respirable crystalline silica was reduced to 0.05 mg/m³ (8-hour TWA) and respirable dust remains 3 mg/m³ — both require atmospheric monitoring and air-monitoring records under Regulation 50.
A SWMS is legally required before this work commences. Failure to prepare, comply with or make the SWMS available constitutes a Category 3 offence under section 33 of the WHS Act, with penalties up to $60,000 for an individual PCBU and $300,000 for a body corporate. This document satisfies Regulation 299 content requirements and is structured to be reviewed and signed on by all workers prior to task commencement.

High-Risk Construction Work triggered
Abrasive blasting liberates RCS (a Schedule 14 sensitiser and Group 1 IARC carcinogen), lead, chromium VI and other toxic substances from substrates and coatings, meeting the definition of work involving hazardous chemicals under Regulation 291(d)
Blasting inside enclosed blast cabinets, storage tanks, pressure vessels, ship holds and pipework satisfies the Regulation 5 confined space definition — restricted entry/egress, designed for limited occupancy and at risk of becoming a hazardous atmosphere from displaced oxygen and dust loading
Because this work is High Risk Construction Work under Regulation 291, a SWMS MUST be prepared before work commences (Reg 299), made available to the principal contractor on request, kept until work is complete (and 2 years if a notifiable incident occurs), reviewed when controls fail or work changes, and stopped immediately if not being followed. Failure attracts penalties up to $6,000 (individual) or $30,000 (body corporate) under Regulation 300, with Category 1–3 offences under WHS Act ss.31–33 escalating to $300,000 / $1.5M / 5 years imprisonment for reckless conduct.

Worked example
A protective coatings crew is contracted to strip and recoat a 30-year-old water storage tank at a regional council depot in NSW. The existing primer tests positive for lead at 4,800 ppm, and internal blasting will occur inside the 6 m diameter steel tank — a confined space. Before mobilisation, the site supervisor downloads this SWMS, populates the project header with the council site address and SafeWork NSW notification reference, and amends the media section to specify garnet 30/60 mesh (silica-free) at 700 kPa nozzle pressure. The hazard register's lead-fume entry is reviewed and confirmed applicable; the confined-space entry permit template is issued for each shift. On day one the crew holds a pre-start toolbox using the worker sign-on register — the blaster, pot tender and stand-by attendant each acknowledge the SWMS in writing. Atmospheric monitoring is conducted by a licensed occupational hygienist on the first full shift; results show RCS at 0.012 mg/m³ and respirable lead at 0.018 mg/m³, both below WES. When the breathing air CO monitor alarms at 12 ppm mid-shift due to a forklift operating near the compressor intake, work stops, the SWMS is reviewed, the intake is relocated 20 m upwind, and the incident is logged. Health monitoring blood-lead samples are collected at week 2 and week 6 per Schedule 14, and spent garnet contaminated with lead is drummed, TCLP tested, and consigned to a licensed waste facility — paperwork retained for the council's regulated-waste audit trail.

Frequently asked questions
Is silica sand still legal to use as a blasting abrasive in Australia?
No. The use of abrasives containing more than 1% free crystalline silica is prohibited for abrasive blasting in all Australian jurisdictions, consistent with the Safe Work Australia Code of Practice: Abrasive Blasting (2021) and ILO Convention 148. Approved substitutes include garnet, slag (copper or coal), glass bead, steel shot/grit, ceramic and plastic media. This SWMS is built around silica-free media selection.
Do I need a confined space entry permit for a blast cabinet?
Yes, where the cabinet meets the Regulation 5 definition of a confined space — restricted entry, not designed for human occupancy and capable of developing a hazardous atmosphere. Most walk-in blast rooms and large industrial cabinets qualify. The SWMS includes a permit-to-work template and references Part 4.5 of the WHS Regulation, which requires atmospheric testing, a stand-by person and a documented rescue plan before entry.
What is the current Workplace Exposure Standard for respirable crystalline silica?
The WES for RCS was reduced to 0.05 mg/m³ as an 8-hour time-weighted average, effective from the SWA review. Air monitoring must be conducted in accordance with AS 2985 by a competent person, and results must be retained for 30 years under Regulation 50. Workers exposed at or above half the WES (action level) require health monitoring under Schedule 14.
Can I use this SWMS for both open blasting and enclosed blast booths?
Yes. The document is structured to cover open-air abrasive blasting (with exclusion zones, containment screens and bystander controls) and enclosed operations including blast cabinets, walk-in rooms and confined-space vessel work. State-specific clauses for NSW, VIC, QLD, WA, SA, TAS, ACT and NT are included so the SWMS is valid across Australia.
How often must this SWMS be reviewed?
Under WHS Regulation 300, a SWMS must be reviewed whenever control measures are revised, the work changes, a notifiable incident occurs, or an HSR requests review. We recommend at minimum a 12-month review cycle and immediate review on any change to media type, substrate coating, or compressor configuration. Free legislation updates are provided for 12 months from purchase.
Does purchasing this SWMS make my company compliant on its own?
No. A SWMS is a planning document — compliance requires that the controls described are actually implemented, that workers are consulted and trained, and that the SWMS is signed on before work and stopped if controls fail. The PCBU must also maintain a hazardous chemicals register, conduct air and health monitoring, and verify worker competency. This document gives you a defensible, auditor-ready foundation.
