Building and pre-purchase inspections require licensed inspectors to enter confined subfloor cavities, traverse pitched roof structures, and assess structural elements that may be compromised, contaminated, or carrying live services. This work is classified as High Risk Construction Work under WHS Regulation 2011 r291 when conducted at heights exceeding two metres or within confined spaces, triggering mandatory SWMS preparation before work commences. Inspectors routinely encounter brittle roofing substrates, friable asbestos in pre-1990 dwellings, biological contaminants in subfloor voids, and degraded structural members that may collapse under load. The combined exposure profile — falls, respiratory hazards, manual handling in restricted postures, and electrical contact — makes this one of the higher-risk inspection disciplines in the residential and commercial property sector. A documented, signed, and worker-consulted SWMS is required under WHS Reg 2011 r299–r300 before any inspector accesses a roof void, cavity, or subfloor, and must be reviewed at each new dwelling type.
Hazards identified
7 hazards covered, sorted by priority.
Fatal or catastrophic fall injuries including spinal fracture, traumatic brain injury, and multi-organ trauma requiring lifelong care
Mesothelioma, asbestosis, and lung carcinoma with 20-40 year latency and no curative treatment available
Electrocution, cardiac arrest, severe burns, and arc-flash injuries from unexpected energised conductors
Asphyxiation, loss of consciousness, and entrapment requiring emergency confined-space rescue response
Leptospirosis, histoplasmosis, hantavirus, and severe allergic respiratory sensitisation requiring hospitalisation
Crush injuries, falls through ceilings, and impact trauma from collapsing structural members and debris
Lumbar disc injury, rotator cuff strain, and chronic musculoskeletal disorders affecting career longevity
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Use drone photogrammetry or pole-mounted inspection cameras for roof and high-cavity assessment to eliminate physical access to brittle or pitched surfaces wherever feasible.
- 2Elimination — Refuse entry to subfloor voids with standing water, visible asbestos debris, or sub-600mm clearance and document refusal in the inspection report.
- 3Substitution — Substitute direct asbestos sampling with visual presumptive identification and recommend a licensed asbestos assessor under WHS Reg r422 rather than disturbing suspect material.
- 4Engineering — Install temporary anchor points compliant with AS/NZS 1891.4 and use a full-body harness with energy-absorbing lanyard for all roof access above two metres.
- 5Engineering — Use a calibrated 4-gas atmospheric monitor (O2, CO, H2S, LEL) before and during subfloor entry per AS 2865 confined space requirements.
- 6Administrative — Conduct documented pre-inspection hazard walk of the property exterior, identify roof material, age indicators, and access points before any elevated or cavity entry.
- 7Administrative — Implement a buddy system with external standby person, two-way radio communication, and 15-minute check-in intervals during subfloor or roof void entry.
- 8Administrative — Restrict inspection duration to maximum 20 minutes in confined subfloor spaces with mandatory rest and rehydration breaks documented on the SWMS sign-on sheet.
- 9PPE — Wear P2 disposable respirator (upgrade to P3 half-face for suspected asbestos), disposable Type 5/6 coveralls, nitrile gloves, and safety eyewear for all void entry.
- 10PPE — Use Class 1 electrical-rated safety footwear, head-torch with hands-free operation, knee pads, and high-visibility long-sleeve workwear for all subfloor and roof activities.
Applicable Codes of Practice
Mandates written SWMS before any work at height over two metres or in confined spaces typical of subfloor and roof void inspection.
Sets the hierarchy of fall controls including anchor systems, edge protection, and competency requirements for inspectors accessing pitched roof structures.
Defines atmospheric monitoring, entry permit, and rescue planning obligations applicable to subfloor cavities with restricted egress and ventilation.
Triggers presumptive asbestos identification duties and prohibition on disturbing suspect ACM during inspections of buildings constructed before 1990.
High-Risk Construction Work triggered
Roof access on residential and commercial buildings routinely exceeds two metres from eaves to ground, triggering mandatory fall-risk SWMS.
Subfloor cavities and sealed roof voids meet the confined space definition with restricted egress, limited ventilation, and potential atmospheric hazards.
Roof and subfloor voids contain live wiring, junction boxes, and unearthed metal services that inspectors contact during structural and pest assessment.
PCBU must prepare, consult workers on, and retain the SWMS for two years after work concludes; penalties for Category 1 breaches are substantial and indexed, with current maximum following the prevailing WHS schedule.

Worked example
On a Tuesday morning a building inspector arrives at a 1972 weatherboard cottage scheduled for pre-purchase inspection. Before unpacking equipment, the inspector opens the SWMS on a tablet at the bonnet of the vehicle and walks through the pre-start brief with the trainee assisting that day. They identify three Schedule 1 HRCW triggers from the document — roof access above two metres on a corrugated metal pitch, a 550mm subfloor void with single access hatch, and visible knob-and-tube wiring in the gable end. Referring to the control hierarchy in the SWMS, they elect to deploy the pole-camera for the upper roof slope (elimination), and reduce the subfloor inspection to a documented visual entry of 15 minutes with the trainee acting as standby person at the access hatch with a two-way radio. Both sign on to the SWMS digitally. Twenty minutes into the subfloor entry, the inspector identifies loose-fill insulation overhead that may contain asbestos. Following the SWMS adjustment trigger, the inspector exits immediately, upgrades from P2 to P3 respirator, marks the area as no-further-entry on the inspection report, and recommends a licensed asbestos assessor in the written client report. The SWMS amendment is logged with time, reason, and signature before any further work continues on site.
