Topsoil and mulch spreading is a core landscaping activity that involves the bulk delivery, placement, grading and compaction of soil, compost and mulch products prior to turf laying or planting. Work typically involves tipper truck deliveries, skid-steer loaders or mini-excavators with bucket attachments, manual barrowing and raking, and the application of pre-emergent herbicides or weed matting. While often perceived as low-risk gardening work, the activity exposes workers to mobile plant, respirable crystalline silica in dry soils, significant manual handling loads, and biosecurity risks from contaminated fill.
Under the model Work Health and Safety Act 2011 and WHS Regulation 2025 (adopted in all states and territories except Victoria, which applies the OHS Act 2004), a Person Conducting a Business or Undertaking (PCBU) has a primary duty of care under section 19 to eliminate or minimise risks to health and safety so far as is reasonably practicable. Regulation 36 requires the hierarchy of control to be applied to all identified hazards, and Part 4.1 specifically governs hazardous manual tasks — directly relevant to mulch and soil handling.
A Safe Work Method Statement is legally required where this work intersects with High Risk Construction Work as defined under Regulation 291 — particularly where spreading occurs adjacent to excavations deeper than 1.5m, near mobile plant movement areas on construction sites, or where airborne contaminants such as silica dust may reach hazardous levels. This SWMS satisfies the documentation requirements of Regulation 299 and aligns with the Safe Work Australia Code of Practice: Hazardous Manual Tasks (2011) and Construction Work CoP (2018).
Hazards identified
8 hazards covered, sorted by priority.
Silicosis, lung cancer and chronic obstructive pulmonary disease; exceeding the 0.05 mg/m³ workplace exposure standard under Regulation 49
Crush injuries or fatality from blind-spot incidents, particularly during tip-up operations and tight-area manoeuvring
Musculoskeletal disorders including lumbar disc injury, rotator cuff tears and chronic lower back pain
Fall into excavation, engulfment by collapsing spoil, or being struck by tools knocked into the void
Vehicle rollover causing operator entrapment and crush injuries to nearby workers
Tetanus, leptospirosis, legionellosis (from compost dust) or needle-stick injury
Heat exhaustion, heat stroke, dehydration and long-term skin cancer risk
Biosecurity Act breach penalties, infrastructure quarantine, and ecological damage to client property
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1ELIMINATE silica exposure where reasonably practicable by specifying pre-moistened topsoil from supplier and rejecting bone-dry loads; maintain soil moisture above 10% during spreading using site-supplied water cart or hose-down before disturbance
- 2ENGINEERING control for mobile plant: establish exclusion zones with physical barriers around tipping areas; use spotters wearing hi-vis with two-way radio contact for all reversing movements; fit reversing cameras and audible alarms compliant with AS 4742 to all loaders and tippers
- 3ADMINISTRATIVE controls including a Traffic Management Plan compliant with AS 1742.3 separating pedestrian zones from plant movement corridors, with a 3-metre minimum exclusion radius around active tipping
- 4Apply hierarchy of control to manual tasks per Hazardous Manual Tasks CoP 2011: use mechanical aids (loaders, motorised wheelbarrows, conveyor chutes) for loads over 20kg; rotate workers every 60 minutes between shovelling, raking and barrowing tasks; restrict bag lifts to two-person handling for sacks over 25kg
- 5Establish a 1.5-metre no-go zone from any open excavation edge; install temporary edge protection or covers to trenches per Regulation 306 before spreading work commences within 2m of the void
- 6Conduct ground stability assessment before each tipping operation; tipper trucks must only tip on level, compacted ground with bucket fully raised only when chassis is confirmed level by driver and spotter
- 7Issue and enforce P2 respirators compliant with AS/NZS 1716 when working with dry materials, conducting fit testing per AS/NZS 1715; provide air-purifying respirators where atmospheric monitoring indicates exposure approaching 50% of the WES
- 8Implement biosecurity controls including supplier certificates of weed-free status, wash-down of plant between sites per state DPI requirements, and rejection of any loads showing fire ant indicators in declared zones (QLD, northern NSW)
- 9Provide PPE per AS/NZS 1800 series: hi-vis vest (AS/NZS 4602.1), steel-cap boots (AS/NZS 2210.3), impact-resistant gloves, wide-brim hard hat, safety glasses (AS/NZS 1337) and SPF50+ sunscreen with reapplication schedule
- 10Implement heat stress management per Safe Work Australia Guide on Working in Heat: shaded rest breaks every 45 minutes when WBGT exceeds 28°C, mandatory hydration (600ml/hour), and work cessation thresholds documented in the site SWMS
- 11Conduct daily pre-start toolbox talks reviewing the day's spreading sequence, plant movements, weather forecast, and any new excavations or services exposed since the previous shift
- 12Maintain emergency response plan including first aid kit (AS 2675 compliant), eye-wash station, communication protocol for plant incidents, and nearest hospital route for crush or respiratory emergencies
Applicable Codes of Practice
Direct application to repetitive shovelling, raking and bag handling — establishes the risk assessment methodology and control hierarchy required under Regulation 60
Applies where spreading is part of a construction project, governing SWMS content, principal contractor duties and HRCW notification under Regulation 299
Relevant where spreading occurs near excavation edges, retaining walls or level changes exceeding 2m
Applies to operators and adjacent workers exposed to skid-steer loader and tipper engine noise above 85 dB(A)
Mandatory where deliveries occur on or adjacent to public roadways, including driveway crossovers in residential landscaping
Governs P2 respirator selection and fit testing for silica dust exposure during dry soil work
Applies to assessment of crystalline silica content in topsoils, decomposed granite and sandy fills
High-Risk Construction Work triggered
Tipper trucks, skid-steer loaders and mini-excavators operate in the same zone as ground workers raking and spreading, creating struck-by and crush exposure that triggers Regulation 291(14)
Triggered where spreading occurs over recently installed irrigation, gas or electrical services in residential and commercial landscape projects, particularly during compaction
Edge-spreading of topsoil along retaining wall footings, drainage trenches or service excavations places workers within the fall and engulfment zone of open excavations
Dry topsoils high in crystalline silica content can generate respirable dust exceeding the 0.05 mg/m³ silica WES during spreading and grading operations
Because this work falls within multiple HRCW categories under Regulation 291, a SWMS MUST be prepared before work commences (Regulation 299), kept available for inspection by an Inspector for the duration of the work, and retained for at least 2 years after a notifiable incident. The Principal Contractor must be provided with the SWMS prior to mobilisation. Failure to prepare or comply with a SWMS attracts penalties of up to $30,000 for an individual and $150,000 for a body corporate under Regulation 300.

Worked example
Daniel runs a four-person landscaping crew contracted to a Class 1a residential builder in Western Sydney. The job involves spreading 45m³ of screened topsoil and 18m³ of hardwood mulch across a 600m² rear yard, with stormwater pits and a 1.8m-deep retaining wall footing trench still open along the eastern boundary. Before the tipper arrives, Daniel uses this SWMS to brief his crew at the pre-start meeting, identifies the open trench as a HRCW Category 5 trigger, and installs star-picket-mounted mesh barriers 1.5m from the trench edge. He confirms the topsoil supplier has provided a moisture certificate above 12% and a weed-free declaration meeting NSW Biosecurity Act requirements. When the tipper arrives, Daniel acts as spotter using a two-way radio while the driver reverses to the tipping point on the level driveway pad. Crew members wearing P2 respirators, hi-vis and steel caps remain in the designated safe zone behind the mesh barrier until tipping is complete and the truck has departed. The skid-steer operator then spreads bulk material while ground crew rotate every 60 minutes between raking, screeding and water-cart hose-down duties. Daniel's signed SWMS, sign-on register and daily pre-start checklist are filed in the site shed and a copy emailed to the Principal Contractor — satisfying his Regulation 299 obligations and providing defensible documentation in the event of a SafeWork NSW inspection.

Frequently asked questions
Do I really need a SWMS for spreading mulch and topsoil — isn't it just gardening?
If your work occurs on a construction site, involves powered mobile plant operating near workers, takes place near excavations deeper than 1.5m, or generates airborne dust exceeding the workplace exposure standard, it triggers High Risk Construction Work under Regulation 291 and a SWMS is legally mandatory under Regulation 299. Most commercial landscaping packages on builder-managed sites meet at least one of these triggers. Penalties for non-compliance reach $30,000 for individuals and $150,000 for companies.
Is silica really a risk in topsoil? I thought that was a stonemason issue.
Many Australian topsoils, decomposed granites and sandy fills contain crystalline silica concentrations between 5% and 80%. When dry material is disturbed by loaders, rakes or wind, respirable crystalline silica becomes airborne and can exceed the 0.05 mg/m³ workplace exposure standard set under Regulation 49. Safe Work Australia's 2024 silica guidance specifically identifies landscaping and earthworks as exposure scenarios requiring control.
Does this SWMS work in all Australian states and territories?
Yes. The document is built on the model WHS Act 2011 and WHS Regulation 2025 framework adopted in NSW, QLD, SA, WA, TAS, ACT, NT and the Commonwealth jurisdiction. The included state-specific legislation schedule notes the equivalent provisions under the Victorian OHS Act 2004 and OHS Regulations 2017 so the SWMS can be applied across all jurisdictions with minor local references.
How often do I need to review and update this SWMS?
Under Regulation 299(2), a SWMS must be reviewed and revised whenever there is an indication that control measures are not effective, before any change to the work that could create a new hazard, after a notifiable incident, or when a HSR requests a review. As best practice we recommend a documented review every 12 months, before each new project mobilisation, and after any near-miss involving the activities covered.
Can I edit the document to suit my specific job?
Yes — the SWMS is supplied as a fully editable Microsoft Word file. Regulation 299 actually requires that a SWMS be specific to the workplace and the way the work is to be carried out, so site-specific customisation is mandatory rather than optional. The template includes prompt fields for site address, principal contractor, plant items, emergency contacts and crew names.
What if I'm a sole trader with no employees — do I still need this?
Yes. Under section 19 of the WHS Act, a PCBU duty applies to sole traders, and the HRCW SWMS requirement under Regulation 299 applies regardless of business size. Additionally, principal contractors and head builders will routinely require a current SWMS as a condition of site induction before allowing you to commence work.
