Hazmat-Controlled Demolition SWMS
Demolition of buildings with multi-hazmat contamination — lead paint, PCB ballasts, asbestos, contaminated soil. Includes hazmat survey, sequenced removal of hazmats before structural demolition, segregated waste streams.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Hazmat-controlled demolition involves the staged dismantling of structures contaminated with multiple hazardous materials — typically lead-based paint, PCB-containing fluorescent ballasts and capacitors, friable and bonded asbestos, and contaminated surrounding soils. The work begins with a Division 6 hazardous materials survey, progresses through sequenced source removal under licensed conditions, and only then permits structural demolition with segregated waste streams tracked to EPA-licensed receivers. Because this work simultaneously triggers multiple High Risk Construction Work categories under Schedule 1 of the WHS Regulation 2025 — including work involving asbestos, demolition of load-bearing elements, and exposure to hazardous chemicals — a Safe Work Method Statement is mandatory before any work commences and must be reviewed at each phase transition. The SWMS must be developed in consultation with workers, signed by all persons performing the work, kept accessible at the site, and retained for the statutory period (or longer where a notifiable incident occurs).
Hazards identified
7 hazards covered, sorted by priority.
Mesothelioma, asbestosis, and lung cancer with 20-40 year latency; PCBU prosecution under WHS Reg 2025 Part 8.7
Blood lead elevation, neurotoxicity, reproductive harm; mandatory health monitoring under WHS Reg 2025 s415
Dermal absorption, hepatotoxicity, persistent environmental contamination, EPA notifiable spill obligations triggered
Worker exposure to lead, hydrocarbons, heavy metals; offsite migration breaching NEPM 1999 assessment levels
Crush injuries, fatal entrapment, secondary release of contaminated dust into breathing zones across the site
Reclassification of entire load as hazardous waste, EPA infringement, six-figure disposal cost escalation
Heat exhaustion, heat stroke, dehydration-induced collapse compounded by reduced PPE doffing frequency
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where structurally viable, retain and refurbish rather than demolish; eliminate the hazmat disturbance pathway entirely by adaptive reuse of the existing envelope.
- 2Elimination — Remove all identified hazardous materials (asbestos, PCB ballasts, lead paint, contaminated soil) under licensed conditions before any structural demolition commences, eliminating combined exposure.
- 3Substitution — Replace dry mechanical stripping of lead paint with chemical gel strippers or infrared paint removers that suppress dust generation at the source.
- 4Substitution — Substitute high-energy demolition (ball, explosive) with low-energy deconstruction using shears and nibblers on contaminated elements to reduce fibre and dust liberation.
- 5Engineering — Establish full negative-pressure enclosures with HEPA-filtered extraction (minimum -5 Pa) for Class A asbestos removal areas per the Code of Practice 2021.
- 6Engineering — Deploy continuous atomised water misting, wheel-wash bays, and perimeter wind fencing to suppress and contain contaminated dust migration from the work zone.
- 7Administrative — Issue a phase-gated demolition sequence permit signed by the supervisor at each transition (survey → asbestos → lead → PCB → soil → structure), with hold points verified by clearance certificates.
- 8Administrative — Conduct daily pre-start SWMS reviews, exposure monitoring per AS 3640, biological health monitoring for lead, and toolbox briefings before any change to scope, plant or substrate.
- 9PPE — Mandate Class P3 full-face powered air-purifying respirators, disposable Type 5/6 coveralls, nitrile under-gloves with chemical over-gloves, and decontamination via three-stage shower unit.
- 10PPE — Provide cooling vests, mandated rest-water-shade cycles, and buddy-system observation when ambient WBGT exceeds 28°C to manage PPE-induced heat load.
Applicable Codes of Practice
Mandates licensed Class A removal, enclosure design, air monitoring, and clearance certification before any demolition of asbestos-containing structures proceeds.
Requires demolition plan, hazmat survey, sequenced removal of hazardous materials, and structural engineer sign-off before load-bearing elements are disturbed.
Governs PCB and lead handling, register maintenance, exposure standards under WHS Reg 2025 Schedule 10, and health monitoring triggers for Schedule 14 substances.
Specifies fit-testing, P3 filter selection, and PAPR maintenance regime required under WHS Reg 2025 s44 for workers in contaminated demolition zones.
High-Risk Construction Work triggered
The final phase removes load-bearing columns, slabs and walls after hazmat strip-out, directly engaging Schedule 1 Category 5 criteria.
Sequenced removal of friable and bonded ACM from the structure is an inherent disturbance activity captured by Schedule 1 Category 10.
Excavators, skid steers and tipper trucks operate continuously within the demolition footprint alongside workers undertaking hazmat handling and segregation.
PCBU must prepare, consult workers on, and retain the SWMS for the statutory period; penalties for Category 1 reckless breaches are substantial and indexed annually under the prevailing WHS penalty schedule.
Who this is for
- →Licensed demolition contractors on contaminated commercial sites
- →Class A asbestos removalists managing combined-hazmat strip-outs
- →Principal contractors on brownfield redevelopment projects

Worked example
On a four-storey 1970s commercial office demolition in a metropolitan CBD, the site supervisor opens the pre-start brief at 6:45am by walking the crew through the Hazmat-Controlled Demolition SWMS at the site shed. The hazmat survey register identifies vermiculite insulation in the ceiling void (Level 3), PCB ballasts across all original light fittings, lead paint on the structural steel, and elevated lead-in-soil readings along the eastern boundary. Using the SWMS hazard matrix, the supervisor confirms today's scope is Phase 2 — PCB ballast removal — and walks through the sequenced controls: isolation and lockout of the distribution board, double-bagging of intact ballasts into UN-approved containers, and immediate spill kit deployment if any capacitor ruptures. Each worker signs the SWMS sign-on register, confirms P3 PAPR fit-test currency, and dons Type 5/6 coveralls at the clean-side decontamination unit. Mid-task, a labourer reports a fractured ballast leaking oil onto the slab. The supervisor halts the area, references the SWMS escalation flowchart, isolates a 3-metre exclusion zone, deploys the PCB spill kit, and amends the SWMS dynamic-risk addendum on the tablet — re-briefing the crew before resuming. The amended SWMS is countersigned and retained with the project hazmat file for the statutory minimum period.
