Cool room and cold storage construction combines structural insulated panel installation with refrigeration plant commissioning, creating a uniquely hazardous interface between mechanical, electrical and confined-space work. Crews routinely manoeuvre heavy expanded polystyrene (EPS) or polyurethane (PUR) sandwich panels at height, charge refrigeration circuits with flammable or asphyxiant gases, and energise three-phase compressors inside partially sealed enclosures. Under WHS Regulation 2011 r291, this work meets the definition of High Risk Construction Work because it involves structural alterations, work at height, mobile plant for lifting, and the use of pressurised refrigerant systems near combustible insulation cores. A Safe Work Method Statement is mandatory before work commences and must be reviewed at every shift change, design variation, or refrigerant changeover. This SWMS template provides a CIH-reviewed, state-neutral framework that PCBUs, principal contractors and refrigeration subcontractors can edit to reflect site-specific plant, panel core type, and commissioning sequence.
Hazards identified
7 hazards covered, sorted by priority.
Rapid flame spread producing toxic isocyanate smoke, structural collapse, fatal inhalation injuries and major property loss
Asphyxiation, chemical burns to airways, cardiac sensitisation or flash fire if ignition source present
Fatal crush of torso or limbs, fractured pelvis, traumatic amputation if panel slips from lifting frame
Fatal or permanently disabling impact injuries, spinal trauma, traumatic brain injury from falls above two metres
Sudden loss of consciousness within seconds, anoxic brain injury, fatal asphyxiation without rescue plan
Third-degree burns, retinal damage, hearing loss from pressure wave, electrocution if isolation incomplete
Lumbar disc injury, cold-induced muscle strain, lacerations from sheet-metal flashing and panel edges
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Specify non-combustible mineral wool core panels at design stage to eliminate PUR/EPS ignition risk per Insurance Council of Australia FR rating guidance.
- 2Elimination — Pre-fabricate refrigeration pipework off-site and pressure-test before delivery to eliminate in-situ brazing inside the partially constructed cool room shell.
- 3Substitution — Substitute A1 classified refrigerants (e.g. R744 CO2) for A2L/A3 flammables where plant duty permits, reducing fire and asphyxiation risk profile.
- 4Substitution — Replace open-flame brazing with press-fit or induction brazing systems to remove hot work ignition sources adjacent to combustible cores.
- 5Engineering — Install fixed refrigerant leak detection with audible alarm and automatic ventilation interlock compliant with AS/NZS 5149.3 before charging plant.
- 6Engineering — Use vacuum panel lifters and engineered spreader bars rated to twice panel mass, with crane exclusion zones marked per AS 2550.1.
- 7Administrative — Implement hot work permit with 60-minute fire watch, refrigerant handling licence verification (ARC AU39), and daily pre-start sign-on against this SWMS.
- 8Administrative — Schedule leak testing and nitrogen pressure tests with confined space entry permits and standby attendant per AS 2865 when shell is sealed.
- 9PPE — Provide cut-5 gloves, safety glasses with side shields, P2 respirators during panel cutting, and arc-rated clothing (HRC 2 minimum) for switchboard commissioning.
- 10PPE — Issue insulated cold-work jackets, anti-slip footwear, and full-body harnesses with twin lanyards anchored to rated points for ceiling panel installation above 2m.
Applicable Codes of Practice
Sets refrigerant charge limits, machinery room ventilation rates and classification of occupancy that govern cool room plant selection and installation.
Specifies mechanical ventilation rates for refrigerant machinery rooms and emergency purge ventilation triggered by leak detection systems.
Defines fall prevention hierarchy applied to ceiling panel installation, condenser mounting and roof-mounted refrigeration plant access above two metres.
Triggers entry permit, atmospheric testing and standby attendant requirements once cool room shell is sealed for leak testing or nitrogen purge.
High-Risk Construction Work triggered
Commissioning three-phase compressors, condensers and switchboards requires live testing of energised refrigeration control circuits and motor starters.
Sealed cool room shells during leak testing, nitrogen purging and refrigerant charging meet the confined space definition under AS 2865.
Refrigeration circuits are charged and pressure-tested with nitrogen and flammable or asphyxiant refrigerants well above atmospheric pressure thresholds.
PCBUs must consult workers, retain this SWMS for two years after the notifiable incident period, and produce it on regulator demand; penalties are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
On a regional cold-chain distribution warehouse fitout, a refrigeration foreman runs the 6:30am pre-start brief beside a stack of 150mm PUR-core panels destined for the 1,200m³ chiller. He opens this SWMS on a ruggedised tablet and walks the four-person crew through the hazard register, pausing on combustible core ignition because hot brazing of the suction line is scheduled for 10am. Using the controls section, the crew confirms press-fit fittings have been substituted for the original brazed joints, eliminating the hot work permit requirement, and the SWMS is annotated with this design change. The leading hand verifies the vacuum lifter's current load test certificate against the engineering controls clause and marks a 4-metre exclusion zone with bollards. Each worker signs on, with the apprentice initialling next to the confined space entry control because he will be the standby attendant during the afternoon nitrogen pressure test. At 1pm a refrigerant delivery arrives earlier than planned with R454B (A2L) instead of the specified R744; the foreman pauses work, reopens the SWMS, reviews the A2L-specific ventilation and leak detection requirements under AS/NZS 5149.1, and confirms the fixed detector is commissioned before authorising the changeover. The amended sign-on captures the substitution and is retained with project records.
