SWMS variants reference your state’s WHS legislation. Instant download after payment.
Concrete slab pours for residential and commercial floor slabs combine multiple high-risk activities into a single time-pressured operation. Crews simultaneously manage formwork integrity, reinforcement positioning, pump line or chute discharge, mechanical vibration, screeding and power-trowel finishing — often while wet concrete is curing on a fixed clock. Under WHS Regulation 2025, slab pours trigger High Risk Construction Work obligations through manual handling of heavy components, exposure to respirable crystalline silica from cement dust and cutting, and work in or adjacent to formwork that could fail under hydraulic load. A documented Safe Work Method Statement is mandatory before work commences, must be developed in consultation with workers performing the task, and must be available at the workplace for the duration of the pour. This SWMS covers the full pour sequence from pre-pour formwork sign-off through to curing handover, aligning with Safe Work Australia's Construction Work Code of Practice and the Managing Risks of Hazardous Chemicals Code.
Hazards identified
7 hazards covered, sorted by priority.
Catastrophic crush injuries, entrapment in wet concrete, fatal asphyxiation, structural damage and project shutdown investigation
Accelerated silicosis, lung cancer, irreversible chronic obstructive pulmonary disease and notifiable occupational disease claims
Acute lumbar disc injury, chronic musculoskeletal disorders, rotator cuff tears and long-term workers' compensation liability
High-velocity strikes causing fractures, eye loss, chemical burns from cement slurry and traumatic head injury
Alkaline chemical burns, allergic contact dermatitis, corneal damage and permanent skin sensitisation to chromates
Ankle fractures, puncture wounds from exposed starter bars, falls into formwork voids and head injuries
Hand-arm vibration syndrome, Raynaud's phenomenon, peripheral nerve damage and notifiable occupational disease over time
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Specify pre-cast or tilt-up panels where design permits, removing the wet pour and associated silica, formwork and manual handling hazards entirely from the site.
- 2Elimination — Eliminate on-site dry-cutting of screed rails and edge boards by ordering pre-cut lengths from the supplier, removing the dominant silica dust generation point.
- 3Substitution — Substitute bagged cement handling with bulk silo or ready-mix truck delivery so workers never break powder bags, dramatically reducing respirable crystalline silica exposure at source.
- 4Substitution — Substitute petrol poker vibrators with low-vibration electric or pneumatic units rated below 2.5 m/s² to reduce hand-arm vibration exposure during compaction.
- 5Engineering — Engage a qualified engineer to design and certify formwork to AS 3610.1 for hydraulic pressure, bracing and props before any pour commences on the slab.
- 6Engineering — Use on-tool water suppression or H-class HEPA vacuum extraction on any concrete saw, grinder or screed rail cut to control silica below the workplace exposure standard.
- 7Administrative — Conduct a documented pre-pour formwork sign-off, toolbox talk and SWMS review with every worker; rotate vibrator and trowel operators on 20-minute cycles to limit vibration dose.
- 8Administrative — Establish exclusion zones around pump lines, post pour-sequence maps, and require radio communication between pump operator, hose handler and screeder throughout the discharge.
- 9PPE — Issue P2 respirators fit-tested to AS/NZS 1715, alkali-resistant nitrile gauntlets, rubber concreters' boots, safety glasses to AS/NZS 1337 and high-visibility long-sleeve clothing.
- 10PPE — Provide barrier cream, anti-vibration gloves to AS/NZS 2161.3, hearing protection rated SLC80 25+ during vibration and power-trowel operations, and immediate eyewash stations within 10 metres.
Applicable Codes of Practice
Mandates engineered design, inspection and sign-off of formwork systems before pour, directly addressing the hydraulic collapse hazard during slab discharge.
Establishes the SWMS preparation, consultation and review duties for High Risk Construction Work including work in or adjacent to formwork.
Sets exposure standard of 0.05 mg/m³ eight-hour TWA, air monitoring triggers and health surveillance obligations for cement dust and cutting tasks.
Requires documented fit-testing, training and maintenance program for P2 respirators worn during silica-generating slab pour and finishing operations.
High-Risk Construction Work triggered
Cast-in-situ slab pours involve placing structural concrete elements whose failure during placement or curing would compromise building structural integrity and worker safety.
Concrete pump trucks, agitator trucks reversing to chute position and power trowels operate within the worker zone throughout the placement sequence.
Handling bagged cement, cutting screed rails and dry-grinding cured surfaces release respirable crystalline silica above the prescribed workplace exposure standard.
PCBUs must prepare the SWMS in consultation with workers before work starts, review it after any incident or method change, and retain records for two years (or the duration of any notifiable incident investigation). Penalties for non-compliance are substantial and indexed; the current maximum follows the prevailing WHS penalty schedule.

Worked example
On a mid-morning pour of a 180 m² suspended commercial floor slab in a regional industrial estate, the leading hand opens the printed SWMS at the site shed for the pre-start brief. He walks the four-person crew and the pump operator through hazards 1, 2 and 4 — formwork collapse, silica dust and pump line whip — using the document's hazard register, then points to the controls list and assigns roles: one worker fit-tested in his P2 respirator handles the cement bag top-up at the pump hopper, another operates the low-vibration electric poker on 20-minute rotation, and the screeder confirms his rubber boots and nitrile gauntlets are on. Each worker signs the SWMS sign-on register, recording their licence numbers and acknowledging the formwork engineer's certificate posted alongside. Forty minutes into the pour, the pump line blocks. The supervisor halts discharge, references the pump line whip control on page three of the SWMS, clears the exclusion zone to ten metres, and only restarts once the hose handler confirms via radio. After the pour, he annotates the SWMS with the deviation, signs the dated amendment line, and stores the document in the site safety file for the mandatory two-year retention period.
