Quick answer: Grinding work commonly requires one or more SWMS because it involves serious hazards including disc shatter, kickback, sparks, silica and metal dust, noise, vibration, and eye injury. The specific SWMS you need will depend on the type of grinder used, the material being ground, the location of the work, and whether sparks or dust create fire, explosion, or health risks on or near the worksite.
Last reviewed: June 2026 by the BlueSafe Technical Team. Reflects current Australian WHS requirements.
Grinding is one of the most common activities across construction, fabrication, and maintenance work in Australia, and it is also one of the most frequently under-documented. A grinder in the right hands with the right controls is a practical and efficient tool. Without adequate hazard controls and a clear safe work method, grinding can cause severe eye injuries, disc shatter fatalities, fires, and long-term lung disease from silica or metal dust exposure. Understanding which SWMS documents apply — and why — helps ensure the work is planned, authorised, and carried out safely.

When does grinding work need a SWMS?
Under Australian WHS legislation, a SWMS is required for High Risk Construction Work (HRCW) on a construction project. Grinding work can trigger HRCW requirements in several ways.
Work at height
Where grinding is performed from a ladder, scaffold, EWP, or elevated platform above 2 metres, the falls over 2 metres HRCW trigger applies. The SWMS must address the fall prevention and work positioning controls relevant to the specific access method, as well as the additional risks of operating a grinder in a restricted or elevated position.
Confined spaces
Grinding inside a confined space — such as a tank, vessel, duct, or excavation — triggers both the confined space HRCW category and significant additional risks. Sparks can ignite accumulated gases or vapours, and dust and fumes can rapidly exceed safe concentration limits in a confined space. Grinding in or near a confined space generally requires a confined space entry permit in addition to a SWMS.
Risk of fire or explosion
Where grinding sparks could reach flammable materials, liquids, dusts, or gases, the risk of fire or explosion must be addressed through a formal hot work permit process. Many principal contractors treat spark-generating work as a HRCW trigger in its own right based on site fire risk assessments, regardless of whether the model WHS Regulations formally classify it as HRCW.
Silica-generating materials
Grinding concrete, masonry, engineered stone, or other silica-containing materials is not itself a HRCW trigger in the traditional sense, but the workplace exposure standards for respirable crystalline silica (RCS) — and the significant penalties now applying to silica dust management failures — mean that any grinding work on silica-containing materials requires documented controls. A dedicated Silica Dust SWMS is increasingly expected by principal contractors as a condition of site entry for work involving these materials.
Note on jurisdiction
Requirements vary across states and territories. Victoria operates under separate WHS legislation to the model WHS framework used in NSW, Queensland, South Australia, Western Australia, Tasmania, the ACT, and the Northern Territory. Duty holders should check applicable regulations and codes of practice for their jurisdiction before commencing grinding work.
Common hazards in grinding work
Grinding generates a combination of hazards that workers, supervisors, and safety managers need to understand in full. The SWMS set for a grinding job should address all applicable hazards, not only the most obvious ones.
- Disc shatter and fragmentation — an incorrect, damaged, or over-speed disc can shatter at high velocity, causing severe or fatal injuries to the operator and bystanders
- Kickback — a grinder can kick back violently if the disc binds, catches, or contacts an unexpected surface; this can result in lacerations, crush injuries, or loss of control
- Sparks and fire — grinding metal generates sparks that can travel several metres and ignite flammable materials, including timber framing, insulation, fuel, dust, and paper
- Silica dust — grinding concrete, masonry, or engineered stone releases respirable crystalline silica particles that, when inhaled, can cause irreversible silicosis, lung cancer, and other serious diseases
- Metal dust and fumes — grinding certain metals such as stainless steel, chrome-coated materials, or zinc-coated surfaces generates toxic metal fumes that require specific respiratory controls
- Noise — angle grinders typically operate above 90 dB(A), and sustained exposure without hearing protection causes permanent noise-induced hearing loss
- Vibration — prolonged use of handheld grinders causes hand-arm vibration syndrome (HAVS), a progressive condition affecting blood vessels, nerves, and joints
- Eye and face injury — sparks, disc fragments, and grinding debris are a primary cause of eye injuries in construction and fabrication settings
- Entanglement — loose clothing, gloves not suited to grinding work, or jewellery can become entangled in the rotating disc or wheel
- Electrical hazards — damaged cords, inadequate RCD protection, and use of incorrect extension leads create electrocution risk with mains-powered grinders
- Heat and burns — workpieces and grinding sparks can cause contact burns; some grinding operations also generate significant heat in the tool or workpiece
Key controls for grinding work
The SWMS set for grinding work should document controls across the following areas. These are not exhaustive — site-specific conditions may require additional controls.
Disc and wheel selection
Using the correct disc or wheel for the material and the grinder is a fundamental control. The disc must be rated for the grinder's maximum RPM, must be appropriate for the material (cutting, grinding, or flap disc), and must be free from damage, cracks, or contamination. A disc or wheel must never be used on a grinder that exceeds its rated speed.
Guarding
The grinder guard must be in place and correctly positioned before use. Removing or repositioning the guard to improve access is a common cause of disc shatter injuries and is not an acceptable work practice. Where the task genuinely cannot be completed with the guard in place, the task method should be reconsidered, not the guard.
RCD protection
All mains-powered electric grinders should be connected through a residual current device (RCD). On construction sites, RCD protection is typically required for all portable power tools. The SWMS should document RCD use and confirm that tools are tested and tagged in accordance with the applicable standard.
Dust control and on-tool extraction
Where grinding generates silica or other hazardous dust, on-tool extraction is the preferred primary control. Vacuum systems with H-class filtration are commonly used for concrete and masonry grinding. Wet grinding methods can also be used where the task permits. Respiratory protective equipment (RPE) is a supplementary control and should not be treated as a substitute for on-tool extraction.
Hot work permit
Where grinding is carried out in an area with fire risk, a hot work permit must be obtained before work commences. The permit process involves assessing the fire risk of the area, removing or protecting combustibles, confirming fire suppression equipment is available and accessible, and arranging a fire watch during and after the work. The duration of the fire watch after grinding ceases is typically a minimum of 30 to 60 minutes, depending on the fire risk assessment outcome.
PPE for grinding
As a minimum, grinding work typically requires safety glasses with side shields or a full face shield, hearing protection (earmuffs or earplugs rated to the noise level), appropriate gloves (anti-vibration gloves where vibration exposure is significant), and leather or protective footwear. RPE appropriate to the dust or fume type is required where airborne contaminants are generated. Cotton or wool clothing is preferred; synthetic materials can ignite from grinding sparks.
Other documents you may need
A SWMS is not the only document that should be in place for grinding work. Depending on the job scope and site, the following supporting documents may also be required or expected.
| Document | When typically needed |
|---|---|
| Site-specific risk assessment | Before commencing grinding in non-standard conditions — elevated work, confined spaces, or areas with significant fire or dust risk |
| Hot work permit | Where grinding sparks could reach flammable materials, gases, or dusts — typically required by the principal contractor or site manager |
| Pre-use inspection record | Before each shift or each time a grinder is set up — confirms disc condition, guard position, RCD connection, and cord integrity |
| Tool and equipment register | Site record confirming that all grinders have been tested and tagged in accordance with AS/NZS 3760 |
| Silica dust control plan | Where regular grinding on silica-containing materials is carried out — documents the hierarchy of controls, exposure monitoring arrangements, and health surveillance obligations |
| RPE selection and fit record | Where respiratory protective equipment is required — confirms that the correct RPE has been selected for the contaminant type and that users have been fit tested where required |
| Toolbox talk record | Pre-start safety discussion covering the specific grinding hazards, controls, and emergency arrangements for that work location |
| Confined space entry permit | Where any grinding is to be carried out inside a confined space — separate from and in addition to the SWMS |
Example scenario
A construction crew is carrying out concrete grinding and weld dressing on a commercial fit-out project. The scope involves grinding back a concrete floor slab for surface preparation before coating, dressing welds on structural steel connections, and cutting bolt holes in a masonry wall adjacent to a storage area containing flammable cleaning products.
For this job, the crew should consider having in place:
- A Grinder SWMS covering the general safe use of grinders across all tasks on site
- An Angle Grinder SWMS covering the portable angle grinder operations for weld dressing and cutting
- A Silica Dust SWMS covering the concrete and masonry grinding tasks, including on-tool extraction setup, RPE selection, and exclusion zone around the dust-generating work area
- A Hot Work SWMS covering the weld dressing and cutting work near the storage area
- A Hot Work Permit obtained from the site manager before any spark-generating work commences near the flammable storage area, with a fire watch in place for the required period after work ceases
- A Power Tools (Electric) SWMS confirming RCD protection, tool inspection, and tagging requirements for all electric grinders on site
- Pre-use inspection records for each grinder used, completed at the start of each shift
- A toolbox talk record covering the silica dust controls, hot work arrangements, and the fire watch procedure for the day's work
This combination gives each major hazard its own clear documentation while the site risk assessment and hot work permit address the site-specific conditions.
Frequently asked questions
Does grinding work require a SWMS?
It depends on the context. Grinding on a construction project can trigger High Risk Construction Work requirements where the work involves risk of falling more than 2 metres, work in confined spaces, or work in areas where sparks could cause fire or explosion. Even where HRCW is not formally triggered, grinding generates serious hazards — disc shatter, kickback, silica dust, fire, and eye injury — and a documented safe work method is generally expected by WHS regulators and principal contractors across Australia. Where grinding work is part of a principal contractor's scope, most sites require SWMS to be in place and consulted before work commences regardless of the formal HRCW classification.
Do I need a separate SWMS for silica dust when grinding concrete or masonry?
Yes, in most cases. Grinding concrete, masonry, or stone generates respirable crystalline silica (RCS), which is a known cause of silicosis, a serious and irreversible lung disease. A dedicated Silica Dust SWMS documents the specific controls for that hazard — including on-tool extraction, wet suppression, RPE selection, and health monitoring obligations — and keeps those controls clearly visible and separate from the general grinding procedure. Many principal contractors now require silica-specific documentation as a condition of site entry for any work involving silica-generating materials, and WHS regulators have significantly increased enforcement activity in this area in recent years.
When does grinding require a hot work permit as well as a SWMS?
A hot work permit is typically required when grinding is carried out in an area where sparks could contact flammable or combustible materials, fuel sources, dusts, or gases. Common examples include grinding near fuel lines, in roof spaces with insulation, near paint or solvent stores, in confined spaces, or on construction sites with exposed timber framing or cladding. The SWMS documents the work method and controls; the hot work permit is an additional site-level authorisation confirming that the area has been assessed and approved for spark-generating work at that specific time. Both documents serve different purposes and are generally required together where fire risk is present.
Can one SWMS cover all types of grinding?
Not usually. Angle grinding, bench grinding, and engineering grinding and linishing each have distinct hazard profiles, equipment requirements, and control measures. A single generic grinding SWMS may not adequately cover the specific risks of each task — for example, angle grinding involves kickback and disc shatter risks from a portable, handheld tool that differ significantly from the nip point, entanglement, and wheel dressing risks associated with a fixed bench grinder. Using purpose-built SWMS for each major grinding activity typically produces more specific, usable documents that workers can actually refer to on the job and that principal contractors will accept as adequate documentation.
