Bark Blower Truck Operations SWMS
Bark blower truck operations covers high-volume mulch placement via hose, projectile hazard zones, eye and respiratory protection during application, and traffic management for street-side mulch supply.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Bark blower truck operations involve pneumatically conveying mulch, compost or erosion control media through a 75–100mm hose at velocities exceeding 30 m/s for placement onto garden beds, batters, revegetation sites and street verges. The work combines mobile plant operation, high-velocity material projection, manual hose handling, and roadside exposure to live traffic — a hazard profile that triggers multiple High Risk Construction Work categories under WHS Regulation 2025 Schedule 1. A documented SWMS is mandatory under WHS Regulation 2025 r299 before work commences, must be developed in consultation with workers per s47, and must remain available for inspection for the duration of the work. The combination of pressurised delivery, dust generation, and shared road corridors means generic landscaping procedures are insufficient — task-specific controls for projectile zones, respiratory protection and traffic management are required.
Hazards identified
7 hazards covered, sorted by priority.
Corneal laceration, globe rupture, permanent vision loss; PCBU liable under WHS Act s32 reckless conduct provisions
Hypersensitivity pneumonitis, occupational asthma, farmer's lung; notifiable illness under WHS Act s37
Fatal pedestrian impact injuries; failure to comply with AS 1742.3 traffic control plan duties
Blunt force trauma to face, fractured limbs, soft-tissue crush injuries to hose handler
Crush injuries, amputation from rotating auger, fatality from reversing collision under r214 plant duties
Lumbar disc herniation, rotator cuff tears, cumulative musculoskeletal injury claims under r60
Permanent noise-induced hearing loss; breach of WHS Regulation 2025 r56 exposure standard
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Eliminate manual hose work near live traffic by completing bark placement during off-peak road closures arranged with the local council under AS 1742.3.
- 2Elimination — Eliminate bystander projectile risk by establishing and barricading a 10-metre exclusion zone around the discharge nozzle before pressurising the system.
- 3Substitution — Substitute high-dust dry bark with pre-moistened or coir-blended media where specification allows, reducing airborne particulate generation at the nozzle.
- 4Substitution — Substitute manual hose handling with a remote-controlled nozzle articulating arm on jobs exceeding 50m³ daily throughput where plant is available.
- 5Engineering — Install hose-end deflector shrouds and ensure auger interlock guards on the loading hopper comply with AS 4024.1 machinery safety requirements.
- 6Engineering — Use truck-mounted variable message signs, flashing amber beacons and water-filled barriers conforming to AS 1742.3 Section 4 for kerbside traffic separation.
- 7Administrative — Conduct pre-start SWMS sign-on briefing identifying the day's exclusion zone, spotter positions, and emergency hose-kill switch location with all crew.
- 8Administrative — Rotate hose operators every 45 minutes to manage manual handling fatigue and limit noise exposure dose under r57 health monitoring obligations.
- 9PPE — Issue P2 respirators fit-tested per AS/NZS 1715, sealed wraparound impact eyewear to AS/NZS 1337.1, and Class 5 hearing protection to AS/NZS 1270.
- 10PPE — Mandate high-visibility day/night garments to AS/NZS 4602.1 Class D/N, steel-cap boots to AS/NZS 2210.3, and impact-rated gloves for all hose handlers.
Applicable Codes of Practice
Triggers PCBU duty under r203–r214 to identify plant hazards, guard rotating augers, and provide operator competency for the blower truck unit.
Mandates traffic guidance scheme, signage taper distances and trained traffic controllers whenever the truck operates within or adjacent to a trafficked carriageway.
Governs P2 respirator selection, fit-testing frequency and storage for crew exposed to organic dust and fungal spores during bark discharge.
Requires noise assessment of the blower unit under r56, audiometric testing per r58, and hearing protector selection where exposure exceeds 85 dB(A) LAeq,8h.
High-Risk Construction Work triggered
The bark blower truck is self-propelled diesel mobile plant operating on construction and roadside sites with reversing, articulation and auger loading hazards.
Pneumatic conveyance pressurises the hose line to project mulch at high velocity, creating stored-energy and projectile hazards consistent with the category criterion.
The PCBU must prepare the SWMS before work starts, consult workers per s47–s49, retain it for the duration of the work plus two years after a notifiable incident, with penalties substantial and indexed; current maximum follows the prevailing WHS schedule.
Who this is for

Worked example
A two-person crew arrives at a suburban arterial road verge to place 40m³ of pine bark across a 180-metre median strip refurbishment for a council streetscape contract. The supervisor opens the Bark Blower Truck Operations SWMS on the tablet at the truck tailgate and walks the operator and traffic controller through the hazard register. They identify that the live two-lane traffic flow elevates the struck-by risk and select the engineering control combination of truck-mounted arrow board, water-filled barriers tapered per AS 1742.3 Figure 4.6, and a dedicated traffic controller positioned 60 metres upstream. The operator confirms his P2 respirator fit-test is current and that wraparound eyewear and Class 5 earmuffs are donned before the auger is engaged. Both workers sign the SWMS sign-on sheet acknowledging the 10-metre projectile exclusion zone and the emergency hose-kill location at the truck cab. Mid-task, a sudden cross-wind begins carrying bark dust toward a pedestrian footpath. The supervisor pauses work, returns to the SWMS, and applies the documented dynamic control — repositioning the discharge angle and activating the moisture injection system to suppress airborne particulate. The amendment is noted on the SWMS revision log, re-briefed to the crew, and work resumes with the updated control in place.
