Dairy processing plant operations encompass receival of raw milk, separation, pasteurisation, homogenisation, standardisation, fermentation and packaging of fluid and cultured products. These tasks expose operators to high-temperature pasteurisers (typically 72-75°C plate heat exchangers), high-pressure homogenisers (up to 250 bar), rotating separator bowls operating above 6,000 rpm, and clean-in-place (CIP) circuits charged with caustic soda (1-4% NaOH) and nitric acid (0.5-1.5% HNO3) at temperatures exceeding 75°C. Under WHS Regulation 2025 and the harmonised model WHS Regulations, dairy processing involves multiple notifiable plant categories, hazardous chemicals above manifest quantities, and confined space entries into silos and tanks — all of which trigger the requirement for a documented Safe Work Method Statement before work commences. This SWMS provides a CIH-reviewed, state-neutral framework aligning with FSANZ Standard 4.2.4, AS/NZS 3500, and the model Code of Practice for Managing Risks of Plant in the Workplace, ensuring PCBUs discharge their primary duty of care under s19 of the WHS Act.
Hazards identified
7 hazards covered, sorted by priority.
Full-thickness chemical burns to skin and cornea, permanent vision loss, and inhalation injury from caustic aerosol exposure
Traumatic amputation, degloving injuries, fatal crush injuries, and prosecution under WHS Reg 2025 plant guarding duties
Fractures, head injuries, lost-time incidents, and back strain from falls onto stainless steel plant edges and drainage channels
Partial and full-thickness burns to hands, forearms and face requiring skin grafting and extended rehabilitation periods
Asphyxiation, loss of consciousness, fatality, and breach of WHS Reg 2025 Part 4.3 confined space permit requirements
High-pressure fluid injection injuries, eye penetration, and crush injuries from uncontrolled valve actuation during isolation failure
Cumulative musculoskeletal disorders, lumbar disc injury, and chronic shoulder impingement reducing workforce capacity
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Replace manual CIP hose make-up with fully automated, hard-piped CIP circuits using dedicated supply and return loops eliminating operator contact with caustic transfer points.
- 2Elimination — Remove the need for confined space entry by installing CIP spray balls, external sight glasses, and remote level instrumentation on all silos and balance tanks.
- 3Substitution — Substitute concentrated caustic (32% NaOH) bulk handling with pre-diluted (4%) closed-dosing systems metered by mag-flow into the CIP set, reducing splash concentration severity.
- 4Substitution — Replace tiled flooring with anti-slip resinous flooring meeting AS 4586 P5 wet pendulum classification in all wet processing and filling zones.
- 5Engineering — Install fixed interlocked guarding on separators, homogenisers and fillers compliant with AS 4024.1601, with Category 3 safety relays and dual-channel monitoring on all access doors.
- 6Engineering — Provide emergency safety showers and eyewash stations within 10 seconds travel of CIP make-up points and chemical dosing skids per AS 4775.
- 7Administrative — Implement a documented Lockout-Tagout-Tryout (LOTOTO) procedure compliant with AS 4024.1603 for all pasteuriser, separator, homogeniser and filler maintenance interventions.
- 8Administrative — Conduct daily pre-start verification of CIP chemical concentrations, pasteuriser flow-diversion valve operation, and confined space gas-test calibration recorded on the SWMS sign-on sheet.
- 9PPE — Issue chemical splash suits to EN 14605 Type 3, full-face shields with chemical goggles to AS/NZS 1337.1, and elbow-length nitrile gauntlets for all CIP interventions.
- 10PPE — Provide AS/NZS 2210.3 SRC-rated slip-resistant footwear, AS/NZS 1270 Class 4 hearing protection in filling halls exceeding 85 dB(A), and thermal gloves for hot-side maintenance.
Applicable Codes of Practice
Mandates risk assessment, guarding to AS 4024 and LOTOTO procedures for separators, homogenisers and packaging plant under WHS Reg 2025 Part 3.1.
Governs caustic and nitric acid storage, bunding, SDS access and manifest quantity reporting triggered by CIP chemical inventories above placard thresholds.
Triggered by entry into silos, balance tanks and CIP return vessels — requires entry permit, atmospheric testing and stand-by attendant under WHS Reg Part 4.3.
Integrates food safety pasteurisation verification (72°C/15s) with WHS thermal hazard controls — ensures process and worker safety are jointly verified.
High-Risk Construction Work triggered
Daily handling of caustic soda and nitric acid above 1% concentration at elevated temperature during CIP make-up and line-break interventions exceeds Schedule 1 thresholds.
Operation and maintenance of high-speed separator bowls, homogeniser plungers and packaging fillers presents entanglement and stored-energy risks captured under Schedule 1.
Continuous wet-floor operation combined with elevated walkways and tank-top access during sampling generates fall and slip exposure meeting Schedule 1 criteria.
PCBU must consult workers under s47-49, retain the SWMS for two years (or duration of any notifiable incident investigation), and review on change of plant or chemistry; penalties for Category 1 breach are substantial and indexed — current maximum follows the prevailing WHS schedule.

Worked example
At a mid-sized regional fluid milk processing plant, the morning shift supervisor convenes a pre-start brief at 05:30 ahead of a scheduled pasteuriser CIP and a filler change-over on the 2-litre HDPE line. The supervisor opens the Dairy Processing Plant Operations SWMS on the shopfloor tablet and walks the four-person crew through the hazard register, focusing on CIP caustic splash, separator entanglement during the post-CIP restart, and wet-floor slip exposure in the filling hall. The crew identifies that today's CIP set is running 3.5% caustic at 78°C and confirms the splash-suit, face-shield and gauntlet PPE matrix in the controls section. The CIP operator verifies the safety shower test tag is current and that the dosing skid interlocks are functional before signing the SWMS sign-on register. Mid-shift, the filler operator notices the in-feed guard interlock has nuisance-tripped; rather than bypassing it, she refers to the LOTOTO administrative control, isolates the line, and calls the maintenance fitter. The supervisor amends the SWMS with a handwritten dynamic risk note documenting the interlock fault, photographs it, and re-briefs the crew before restart. The completed, annotated SWMS is uploaded to the plant's WHS records system at end of shift, demonstrating live use of the document as a working risk-control tool rather than a filed compliance artefact.
