Civil-grade water tankers (water carts) are deployed on earthworks, haul roads, quarry pads and bulk excavation sites to suppress respirable crystalline silica and nuisance dust generated by mobile plant, hauling and wind erosion. Operating a 10,000–30,000 litre articulated or rigid water cart constitutes High Risk Construction Work under WHS Regulation 2011 r291 because it involves the use of mobile plant in proximity to workers, traffic interaction on shared haul roads, and work that may disturb or contaminate live surfaces near excavations. A documented Safe Work Method Statement is mandatory before the task commences, must be developed in consultation with operators and ground crew under s47–48 of the WHS Act, and must remain accessible on site for the duration of the activity. This SWMS template addresses tanker pre-start, spray pattern management, haul road interaction, slip/saturation control and silica exposure verification across all eight Australian jurisdictions.
Hazards identified
7 hazards covered, sorted by priority.
Fatal crush or run-over injury; coronial inquest, PCBU prosecution and Category 1 reckless conduct charge under s31
Operator entrapment, fatal cabin intrusion; mobile plant duty breach under WHS Reg r213 with ROPS verification failure
Secondary collisions, articulated truck jackknife, downhill runaway; multiple plant damage and worker injury claims
Accelerated silicosis, lung cancer, compensable dust disease; exceedance of 0.05 mg/m³ WES under WHS Reg r49
High-pressure water injection injury, eye trauma, hose whip strike to ground crew within 15-metre arc
Crush fatality or plunge into excavation; breach of r215 mobile plant separation and reversing controls
Lumbar strain, fall from tank walkway (>2m); notifiable incident under WHS Act s37 if hospitalisation results
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where dust source can be sealed (bitumen primer, polymer crust, vegetation), eliminate water cart passes entirely on completed pads and inactive stockpile faces.
- 2Elimination — Remove all non-essential personnel from the active watering corridor by establishing a tanker-only exclusion zone signposted at each haul road intersection.
- 3Substitution — Substitute potable water with approved hygroscopic dust suppressant (calcium chloride or lignosulfonate) on haul roads to extend cycle time and reduce tanker movements by 60–70%.
- 4Engineering — Fit tanker with reversing camera, 360° proximity radar, ROPS/FOPS-certified cabin, internal anti-slosh baffles and amber/blue strobes compliant with AS 4602.1 high-visibility plant marking.
- 5Engineering — Install positive shut-off on spray bar and rear cannon with deadman control in cab so spray cannot continue if operator is incapacitated or exits the cabin.
- 6Engineering — Maintain haul road crossfall and apply water at calibrated rate (typically 0.5–1.5 L/m²) using flow-metered spray bars to prevent over-saturation and tracked slurry runoff.
- 7Administrative — Conduct documented pre-start inspection, sign-on to this SWMS, two-way radio channel confirmation with haul truck operators, and JSA review at shift change and after rain events.
- 8Administrative — Schedule watering passes against haul truck cycles using a traffic management plan compliant with AS 1742.3, with positive communication before entering loading or tipping zones.
- 9Administrative — Air monitoring for respirable crystalline silica per AS 2985 quarterly and after method change, with results communicated to workers under WHS Reg r50 health monitoring duty.
- 10PPE — Operators and ground crew wear AS/NZS 1801 hard hat, AS/NZS 4602.1 day/night hi-vis, AS/NZS 2210.3 steel-cap boots, AS/NZS 1337.1 eye protection and P2 respirator when exiting cab in active dust.
Applicable Codes of Practice
Mandates hierarchy of control application and consultation when selecting dust suppression method and tanker exclusion zones under r36 risk management.
Sets duties for mobile plant inspection, operator competency, ROPS/FOPS verification and traffic management around water carts under WHS Reg r203–r214.
Required signage, speed control and positive communication for water tanker operation on haul roads shared with public or contractor traffic.
Triggers air monitoring, health surveillance and engineered suppression duties when tanker is used to control respirable crystalline silica exposure.
High-Risk Construction Work triggered
A water cart is powered mobile plant operating on civil sites alongside workers, haul trucks and graders, directly invoking the r291(n) HRCW criterion.
Tanker operates on live haul roads and frequently accesses public road interfaces for fill, exposing operator and crew to traffic interaction risks.
Tank lid access and walkway use above 2m height during fill creates fall-from-height exposure captured under associated HRCW fall and access criteria.
PCBUs must prepare, consult workers on, and retain this SWMS for the duration of the work plus two years after a notifiable incident; penalties for Category 1 breaches are substantial and indexed, with the current maximum following the prevailing WHS schedule.
Who this is for

Worked example
On a regional highway upgrade earthworks package, the day-shift water cart operator arrives for a 6:00 am pre-start brief held at the site office demountable. The supervisor opens this SWMS on the tablet and walks the operator and two ground crew through the seven listed hazards. Overnight rain has saturated the southern haul road, so the crew flags hazard 3 (haul road saturation) as the live risk and agrees the tanker will only water the northern alignment until the southern pad dries — a control selection straight from the engineering tier of the SWMS. The operator confirms reversing camera, radar and rear cannon deadman are functional on the pre-start checklist, signs on to the SWMS sign-on register, and confirms UHF Channel 12 with the four articulated dump truck operators. At 10:30 am a survey crew arrives unannounced near the tipping face; the spotter halts the tanker, the supervisor returns to the SWMS, adds the surveyors to the exclusion-zone briefing, has them sign on, and re-confirms positive radio communication before watering resumes. The SWMS is re-signed at the post-lunch restart after the wind shifts and a P2 respirator control is escalated for the ground crew working near the loading face.
