Blown or loose-fill cellulose insulation installation involves pneumatically conveying treated paper-based fibre through hoses into ceiling cavities, wall cavities and crawl spaces using a mechanical blower unit. The work is classified as High Risk Construction Work under WHS Regulation 2011 r291 because installers routinely access confined ceiling crawl spaces, work near energised wiring and recessed downlights, and are exposed to elevated airborne dust concentrations including cellulose fibre, ammonium sulphate or borate fire retardants, and historical contaminants disturbed during entry. A Safe Work Method Statement is mandatory before work commences and must be developed in consultation with workers under WHS Act s47, kept available for inspection on site, and reviewed whenever controls fail or conditions change. This template addresses the full task sequence — pre-entry inspection, blower setup, hose management, cavity navigation and post-work decontamination — and aligns controls with the hierarchy under WHS Regulation r36.
Hazards identified
7 hazards covered, sorted by priority.
Electrocution, arc flash burns, fatal cardiac arrest, or ignition of cellulose causing structural ceiling fire and occupant fatality
Fall from height onto floor below causing spinal injury, multiple fractures, traumatic brain injury or death
Acute respiratory irritation, hypersensitivity pneumonitis, histoplasmosis, mesothelioma latency, and chronic occupational lung disease
Heat exhaustion, syncope, rhabdomyolysis, cardiovascular collapse and loss of consciousness in confined space without rescue access
Acute lumbar disc injury, rotator cuff tears, chronic musculoskeletal disorders and permanent vocational impairment
Whip injury from disconnected coupling, eye injury from blown debris, and falls caused by hose snag at hatch
Disorientation, loss of cavity navigation reference points, increased fall risk and respiratory protection seal failure
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where loose-fill is specified purely for thermal performance, substitute the design with externally applied batt or rigid board insulation accessed from outside the cavity, removing crawl space entry entirely.
- 2Elimination — Isolate and lock out the entire roof-space electrical circuit at the switchboard before entry, eliminating live contact risk under AS/NZS 3000 clause 2.3 isolation requirements.
- 3Substitution — Substitute borate-treated cellulose for ammonium-sulphate formulations to reduce acute respiratory irritation and corrosivity to metal fixtures, per safety data sheet selection under WHS Reg r328.
- 4Engineering — Install temporary LED task lighting and crawl boards spanning joists across the full work path so installers never bear weight on plasterboard sheeting between joists.
- 5Engineering — Use blower units fitted with variable-speed control and hose-end shut-off trigger so discharge can be stopped instantly if the operator loses footing or visibility.
- 6Engineering — Provide forced cavity ventilation using a portable extraction fan ducted to outside air, reducing airborne dust and lowering cavity temperature during the task.
- 7Administrative — Conduct pre-entry asbestos and hazardous material assessment per the Code of Practice: How to Manage and Control Asbestos in the Workplace before any pre-2004 ceiling cavity entry.
- 8Administrative — Implement a two-person buddy system with external standby observer, radio communication, scheduled rotation every 30 minutes, and documented heat-stress monitoring against BoM forecast.
- 9PPE — Issue P2 half-face respirators with fit-testing per AS/NZS 1715, disposable Type 5 coveralls, safety glasses to AS/NZS 1337.1, nitrile gloves and knee pads for sustained kneeling.
- 10PPE — Upgrade to powered air-purifying respirator (PAPR) with P3 filter for cavities exceeding 35°C or where dust visibility falls below one metre during continuous discharge phases.
Applicable Codes of Practice
Work in a confined ceiling cavity with risk of fall and electrical contact triggers mandatory SWMS preparation, consultation and on-site availability.
Sets the duty to provide crawl boards, edge protection at hatches, and fall arrest where joist spacing or ceiling fragility creates a fall-through risk.
Mandates fit-testing, filter selection for nuisance and hazardous dust, and supervisor training before P2 or PAPR units are issued to installers.
Requires pre-entry assessment of pre-2004 ceiling cavities for asbestos-containing dust before any disturbance by blown insulation installation activity.
High-Risk Construction Work triggered
Sealed ceiling cavities with single restricted access hatch, limited ventilation and accumulating dust meet the confined space definition under WHS Reg r5.
Installers routinely encounter live ceiling wiring, recessed downlight transformers and junction boxes concealed beneath existing insulation during cavity navigation.
Standard residential ceiling cavities sit above a 2.4m floor, and fall-through of plasterboard between joists exceeds the 2 metre threshold.
PCBU must prepare, consult workers on, and retain the SWMS for the duration of the work plus two years after a notifiable incident; penalties for non-compliance are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
On a suburban single-storey weatherboard retrofit under a state energy efficiency rebate, the two-person crew arrives to blow 250mm of cellulose into a 1960s ceiling cavity accessed through a 600x600 manhole in the hallway. At the pre-start brief on the tailgate, the supervisor opens this SWMS on a tablet and walks the installer through each hazard line. They confirm the switchboard has been isolated and tagged because the SWMS lists concealed wiring as a HIGH priority item, and they identify two recessed downlights from the floor plan that require IC-rated covers before discharge. The SWMS prompts an asbestos pre-check — the supervisor inspects the cavity with a torch from the hatch, sights vermiculite-free fibreglass batts, photographs the cavity and signs off the assessment row. Both workers fit-test their P2 respirators against the AS/NZS 1715 control listed, don Type 5 coveralls and sign the consultation register on page four. Thirty minutes into discharge the installer radios that cavity temperature is climbing and visibility has dropped below one metre. The standby observer refers back to the SWMS PAPR trigger threshold, halts work, swaps the half-face for a PAPR unit, and amends the live SWMS record with the control change, time and reason before resuming.
