Demolition and removal of in-ground swimming pools — whether reinforced concrete shell or fibreglass monocoque — presents a convergence of high-risk construction work hazards that demand a documented Safe Work Method Statement before any tool is started on site. The work sequence involves draining residual water, isolating and disconnecting electrical bonding and hydraulic services, mechanically breaking up the shell with an excavator-mounted hydraulic hammer or pulveriser, segregating and removing debris, then backfilling the void with engineered fill compacted in lifts. Each stage triggers separate duties under WHS Regulation 2025, including High Risk Construction Work under section 291 categories for work in or adjacent to an excavation greater than 1.5 metres, and exposure to respirable crystalline silica generated during concrete breakup. A PCBU undertaking this work must prepare, consult on, and implement a SWMS before work commences, and must stop work if controls are not implemented as documented. This SWMS template captures the hazard chain, the hierarchy-of-control responses, and the supervisor sign-on workflow expected by regulators during a site visit.
Hazards identified
7 hazards covered, sorted by priority.
Fall from height exceeding 2 metres causing fractures, head injury, or drowning in residual water and sludge.
Chronic silicosis, accelerated lung function decline, lung cancer, and notifiable occupational disease under state health regulations.
Electrocution or arc flash injury to operators contacting reinforcement during mechanical breakup of shell.
Crush injury, traumatic asphyxia, and fatality from unsupported soil batter exceeding 1.5 metres depth.
Blunt force trauma, amputation, or fatality from contact with bucket, hammer attachment, or counterweight.
Skin and respiratory irritation, eye penetration injuries, and dermatitis from cured polyester resin particulate.
Environmental prosecution under state EPA legislation and chemical burns to workers handling residual liquids.
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Where possible, abandon-in-place the lower shell by perforating the base, removing only the upper 500mm and backfilling, eliminating deep excavation entry.
- 2Elimination — Schedule mechanical breakup only after full drain-down and chemical neutralisation is verified, eliminating worker entry into water-bearing voids.
- 3Substitution — Substitute dry concrete breaking with continuously wetted hydraulic hammering using on-tool water suppression to substitute dust-generating dry methods.
- 4Engineering — Batter excavation walls to a maximum 1:1 slope or install shoring per AS 5047 before any worker enters the void to cut reinforcement.
- 5Engineering — Fit excavator with cabin filtration rated P2 and use water cart misting at the breakup face to suppress respirable silica below the workplace exposure standard.
- 6Engineering — Lock out and tag all electrical circuits feeding pool equipment at the switchboard and verify dead with a tested voltage indicator before reinforcement is cut.
- 7Administrative — Establish a 1.5 times machine reach exclusion zone marked with bunting and enforced by a dedicated spotter in radio contact with the operator.
- 8Administrative — Conduct a documented pre-start SWMS sign-on each shift, confirming silica monitoring, exclusion zones, and emergency rescue arrangements are current.
- 9PPE — Issue P2 half-face respirators (or PAPR for sustained breakup tasks), impact safety glasses, hi-vis, steel-cap boots, and cut-resistant gloves to all crew within the work area.
- 10PPE — Provide chemical-resistant gloves and splash goggles to the worker handling residual pool chemistry and decanting neutralised water to approved disposal.
Applicable Codes of Practice
Specifies SWMS, demolition plan, service isolation verification, and exclusion zone duties for structural demolition including in-ground pool shells.
Triggers ground assessment, shoring or battering requirements, and emergency rescue planning for the pool void exceeding 1.5 metres depth.
Imposes water suppression, air monitoring, and health surveillance obligations during mechanical breakup of concrete pool shells generating respirable silica.
Governs edge protection during shell breakup and confined space classification if the partially demolished shell restricts egress or atmosphere.
High-Risk Construction Work triggered
The pool shell is a load-bearing reinforced concrete structure retaining surrounding soil; its mechanical breakup directly engages this section 291 trigger.
Mechanical hammering and pulverising of the concrete shell generates respirable crystalline silica, triggering this category regardless of duration.
PCBU must prepare the SWMS, consult workers performing the work, retain it for the duration of the project plus two years after a notifiable incident, with penalties substantial and indexed; current maximum follows the prevailing WHS schedule.

Worked example
On a suburban knock-down-rebuild block, a two-person demolition crew arrives to remove a 9 metre concrete in-ground pool ahead of a new dwelling slab. Before the excavator is unloaded, the supervisor opens this SWMS on a tablet at the tailgate and walks through the hazard register with the operator and the labourer. They confirm the pool was drained the previous day, the pump shed has been isolated and tagged at the meter board, and a voltage tester has verified the bonding wire is dead. The supervisor identifies that the deep end measures 2.1 metres, triggering the excavation HRCW category, so the SWMS instructs them to batter the walls to 1:1 as breakup progresses and to never enter the void without a second person topside. Water suppression is set up using a poly tank and misting nozzle on the hammer face to control silica. Both workers initial the sign-on sheet acknowledging P2 respirator use and the 8-metre exclusion zone. Mid-morning, the operator strikes an unexpected steel beam at the shell base; work stops, the supervisor reopens the SWMS, adds a controlled change note for oxy-cutting and re-briefs the labourer on hot work and fume control before resuming. At shift end, the signed SWMS and change record are filed against the project for the retention period required under WHS Regulation 2025.

Frequently asked questions
Do we need a SWMS just to take out a backyard pool?
Yes, in most cases, because the scale of the job does not change the trigger. A reinforced concrete pool shell is a load-bearing structure retaining the surrounding soil, so breaking it up is demolition of an element related to the physical integrity of a structure under s291(c). A standard in-ground pool is deeper than 1.5 m at the deep end, so the void left behind is a shaft or trench under s291(g). Either one on its own makes this high risk construction work, and section 299 then requires the SWMS before work commences.
Do we have to remove the whole shell, or can we abandon it in place?
Abandon-in-place is often the lower-risk option and the SWMS treats it as the elimination control: perforate the base so the void drains, remove the top 500 mm or so of shell, and backfill with engineered fill compacted in lifts. That avoids anyone entering a deep excavation to cut reinforcement at all. Where full removal is required, nobody enters the void until the walls are battered to a maximum 1:1 slope or shored to AS 5047. Whether abandon-in-place is acceptable depends on the certifier and what is being built over it, so confirm that before pricing the method.
What has to be isolated before the hammer touches the shell?
Everything electrically connected to the pool, and that is more than the pump. Pool lights, circulation pumps and salt chlorinators are supplied circuits, and the reinforcement in the shell is usually equipotentially bonded — meaning the steel the operator is about to break is part of the electrical system. The controls require lock-out and tagging at the switchboard and verification dead with a tested voltage indicator before any reinforcement is cut. Hydraulic services are isolated and disconnected at the same time, because a charged line released under a hammer is a hazard in its own right.
Does this cover fibreglass pools, or only concrete shells?
Both. A fibreglass monocoque shell presents a different hazard picture from concrete: cutting cured GRP releases resin shards and polyester particulate rather than respirable silica, causing skin and respiratory irritation, dermatitis, and eye penetration injuries from flying fragments. The document carries that hazard separately, with impact eye protection and cut-resistant gloves specified for the crew doing the cutting. Concrete shells bring the silica pathway instead, controlled by continuously wetted hydraulic hammering with on-tool water suppression, water cart misting at the breakup face, and P2-rated cabin filtration on the excavator.
What do we do with the water and the leftover pool chemicals?
Not put them down the stormwater drain. Chlorinated pool water and acidic balancing chemicals discharged to stormwater is an environmental offence in every state, and residual chemistry sitting in the deep end also burns the skin of whoever wades in to check it. The SWMS sequences full drain-down and verified chemical neutralisation before mechanical breakup begins, so nobody is working over a water-bearing void. The worker decanting neutralised water to approved disposal wears chemical-resistant gloves and splash goggles. Getting this wrong turns a one-day demolition into a remediation problem.
