Insulated Sandwich Panel Installation SWMS

Insulated sandwich panel installation involves lifting and fixing large-format composite panels — typically a polyisocyanurate, polyurethane, mineral wool or expanded polystyrene core sandwiched between profiled steel skins — to structural framing for cold rooms, food processing facilities, warehouses and industrial cladding. Panels are commonly 6–12 metres long, awkward to handle in wind, and must be installed at height using scissor lifts, boom lifts or scaffold. The work exposes workers to falls from height, crush injuries from swinging panels, cuts from sheet metal edges, and — critically — combustible core materials that present a serious fire risk during hot work and after installation.

Under the Work Health and Safety Regulation 2025 (NSW), this work is high risk construction work under section 291 because it involves a risk of a person falling more than 2 metres, structural work requiring temporary support, and the use of powered mobile plant. Section 299 requires a Safe Work Method Statement to be prepared before the work commences, in consultation with workers under section 47. Controls follow the hierarchy in section 36, prioritising elimination of work at height where feasible.

Control measures

Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.

1. 1Eliminate work at height where possible by pre-assembling panel modules at ground level and lifting complete sections into position using engineered lifting frames.
2. 2Substitute combustible core panels with non-combustible mineral wool core panels where the building classification, insurer requirements or FRL demands it; verify core type against manufacturer CodeMark certification before delivery.
3. 3Engineer fall protection through perimeter edge protection, scaffold with handrails, or elevating work platforms selected and used in accordance with AS 2550.10 and AS/NZS 1418.10; where these are not reasonably practicable, use a travel-restraint or fall-arrest system compliant with AS/NZS 1891.1 and AS/NZS 1891.4 with a documented rescue plan.
4. 4Engineer safe lifting using purpose-built panel clamps, vacuum lifters or spreader beams rated for the panel mass and length; lifting gear inspected and tagged in accordance with AS 2550.1 and the manufacturer's instructions.
5. 5Provide temporary bracing and propping to panels immediately upon placement and before releasing lifting equipment, in accordance with the structural engineer's temporary works design; do not leave panels unrestrained overnight.
6. 6Establish exclusion zones beneath and around lifting operations using hard barriers and spotters; suspend lifting operations when wind speed exceeds the manufacturer's or EWP's rated limit (typically 10 m/s) measured with an on-site anemometer.
7. 7Eliminate hot work adjacent to combustible panel cores wherever possible; where unavoidable, implement a hot work permit system with fire watch, extinguishers, non-combustible barriers to expose foam core, and post-work monitoring for a minimum 60 minutes.
8. 8Control silica and isocyanate exposure by using shadow-vac cutting tools with on-tool extraction (H-class), wet cutting for masonry penetrations, and by prohibiting flame cutting or grinding of foam cores; provide RPE selected under AS/NZS 1715 and AS/NZS 1716 (minimum P2, half-face reusable for silica tasks).
9. 9Separate powered mobile plant from workers on foot using physical exclusion barriers, high-visibility clothing to AS/NZS 4602.1, spotters with two-way radios, and a traffic management plan; verify overhead powerline clearances under the SafeWork NSW Code of Practice: Work Near Overhead Power Lines.
10. 10Provide cut-resistant gloves rated to AS/NZS 2161.3, safety eyewear to AS/NZS 1337.1, safety footwear to AS/NZS 2210.3 and hard hats to AS/NZS 1801 as final-layer PPE.
11. 11Verify all workers hold a current General Construction Induction (White Card, CPCCWHS1001), EWP licence or Yellow Card as applicable, and high-risk work licences for any crane or forklift operation.
12. 12Consult with workers on the SWMS under section 47 of the WHS Act 2011 (NSW), sign on all personnel before work commences, and review the SWMS under section 302 of the WHS Regulation 2025 (NSW) whenever controls change, an incident occurs, or the work method is modified.

High-Risk Construction Work triggered

Worked example

A cladding subcontractor is engaged to install 8.4-metre mineral-wool-core sandwich panels to the walls and ceiling of a new 2,400 m² cold storage facility in Eastern Creek, western Sydney. The work involves a 19-metre diesel scissor lift and a 17-metre telehandler with a panel clamp attachment. Workers install panels at heights ranging from 3 m to 11 m over a six-week program. Before mobilising, the site supervisor prepares this SWMS, identifies a high risk construction work category under section 291, and consults the four-person install crew under section 47 of the WHS Act. A structural engineer's temporary bracing detail is attached. When high winds are forecast mid-program, work is suspended, the anemometer trigger is documented, and the SWMS is reviewed under section 302 before the crew resumes with a revised lifting sequence.
