This SWMS covers the full scope of machine guarding and safeguarding activities on Australian industrial plant — routine guard inspection, interlock function testing, light-curtain alignment and blanking checks, two-hand control validation, fixed-guard installation and replacement, movable-guard interlock commissioning, adjustable-guard setup on manual machinery, presence-sensing mat testing, emergency-stop function verification, and the competent-person certification of machines following modification or major repair. It is written for maintenance fitters, production engineers, machine-safety specialists, plant supervisors, and WHS leads responsible for keeping powered plant in compliance with Part 4.5 of the WHS Regulation 2025 and the AS/NZS 4024 series of machinery-safety standards. It applies across manufacturing, food processing, timber milling, metal fabrication, printing, packaging, and any workplace that operates guarded plant with moving parts capable of causing entanglement, crushing, shearing, cutting, or ejection injuries.
Machine guarding does not sit in the Schedule 1 list of high-risk construction work categories. However, the underlying duty is every bit as binding. Part 4.5 of the WHS Regulation 2025 imposes a comprehensive duty on any PCBU with management or control of plant to manage risks associated with plant and structures, and Regulation 208 specifically requires that where access to a hazardous part of plant cannot be eliminated, the risk must be controlled by a fixed guard, an interlocked movable guard, a presence-sensing system, or — only as a last resort — administrative controls. Regulation 209 imposes additional operational-control duties, Regulation 213 imposes maintenance and inspection duties, and Regulation 214 imposes specific obligations for powered mobile plant. The AS/NZS 4024 series provides the detailed technical framework — AS/NZS 4024.1201 establishes the general risk-assessment methodology, AS/NZS 4024.1501 governs interlocking devices associated with guards, AS/NZS 4024.1102 governs two-hand control devices, and AS/NZS 4024.1801 governs the design and selection of fixed and movable guards. The 2024 enforcement record is instructive: a Queensland timber mill was fined $300,000 in December 2024 after a worker was killed operating an unguarded de-barker, and Paving Group Pty Ltd (Quantumstone) was fined $75,000 in August 2024 after a traumatic conveyor-roller injury. In both cases the regulator found that guards had been removed or not installed and no compensating administrative control was in place. Because machine guarding does not trigger a Schedule 1 HRCW category, this SWMS is not required by Section 299 of the WHS Regulation, but it remains the most defensible mechanism for documenting compliance with the Part 4.5 plant duty, for induction and training records, and for Principal Contractor due-diligence.
Hazards identified
12 hazards covered, sorted by priority.
Severe laceration, amputation, de-gloving, or fatality from clothing, hair, jewellery, or gloves drawn into rotating plant; the leading cause of Australian machine fatalities.
Fatal or permanent crush injury when hands, arms, or torso are caught between a ram and a die, between a closing guard and a fixed point, or between two moving machine elements.
Amputation of fingers, hands, or forearms from scissoring actions on sheet-metal guillotines, paper slitters, and food slicers without adequate guarding.
Deep lacerations and severance injuries from direct contact with saw teeth, food-processing blades, and bonded abrasive grinding wheels.
Fatal or permanent head and torso injury from components ejected at high velocity during turning, milling, and grinding operations with inadequate chuck guards or wheel guards.
Penetrating injury from reciprocating needles on industrial sewing, upholstery, or food-processing machinery where needle guards are missing or bypassed.
Severe friction burns and skin avulsion from contact with moving belts, abrasive wheels, and rapid-sanding drums without peripheral guards.
Contact burns during maintenance of plant that retains heat — hot-melt applicators, extruder barrels, plastic-moulding dies, and food-oven components — before cool-down is complete.
Noise-induced hearing loss and hand-arm vibration syndrome when operators work adjacent to unshrouded grinding, sawing, and pressing operations without peripheral enclosure.
Loss of the protective function, leading to operator injury during maintenance or production; the root-cause finding in a substantial proportion of Australian machine-guarding prosecutions.
Plant returned to service with a guard missing, an interlock bypassed, or a light curtain misaligned; subsequent operator injury on the next production shift.
Musculoskeletal injury from repetitive reaching through small guard openings, lifting workpieces over fixed guards, and unnatural postures imposed by poorly designed safeguarding.
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Eliminate the hazard point where reasonably practicable — redesign the machine layout with remote loading, automated feed systems, or robotic material handling so that workers never reach into the danger zone during normal operation.
- 2Substitute lower-energy processes where elimination is not practicable — slower feed rates, smaller cutting tools, reduced-closing-force press programmes — to reduce the consequence of inadvertent contact.
- 3Install fixed physical guards in accordance with AS/NZS 4024.1801. Guards are bolted or riveted in place, require a deliberate tool-assisted removal, and prevent reach-over, reach-under, reach-around, and reach-through based on the safety distances tabulated in AS/NZS 4024.1801.
- 4Install interlocked movable guards with dual-channel safety relays, keyed-switch or magnetic-switch sensors, and logic designed to AS/NZS 4024.1501. Interlocks must achieve the performance level required by a task-specific risk assessment per AS/NZS 4024.1201 — typically Performance Level d (PLd) for Category 3 hazards.
- 5Install presence-sensing systems where fixed or interlocked guards are impracticable — light curtains to AS/NZS 4024.1501, safety mats, laser scanners, and two-hand controls to AS/NZS 4024.1102. Blanking and muting configurations must be documented and verified at commissioning and at each subsequent function test.
- 6Install emergency stops at every operator position within easy reach — mushroom-head pushbuttons, pull-cord systems along conveyors, and kick-bar emergency stops on food-processing plant — compliant with AS/NZS 4024.1602 and integrated with the safety-related control system.
- 7Conduct and document pre-shift interlock and emergency-stop function tests on production plant. Operators verify that each interlocked guard stops the plant on opening and that each emergency stop latches in the stopped state. Log the test in the daily production-start record.
- 8Schedule a monthly competent-person guard and safeguarding audit using a documented checklist. The audit confirms guard integrity, interlock function, light-curtain alignment, fastener condition, and the absence of bypass wiring. Non-conformances are tagged, removed from service, or locked out until corrected.
- 9Apply lockout/tagout every time a guard is removed for maintenance. No maintenance is permitted on plant with a removed guard unless the plant is fully isolated per the separate LOTO procedure and a personal danger lock is applied by every worker exposed to the hazard.
- 10Conduct a controlled restart sequence after any guard removal or safeguarding intervention. All tools and foreign objects removed from the plant envelope, all guards refitted and fasteners torqued, all interlocks function-tested, all personnel clear, and a supervised test run completed before production resumes.
- 11Competency-based operator training and written authorisation per machine. No worker operates guarded plant without a documented induction to that specific machine covering the guards, interlocks, safe-work procedure, and the correct response to a guard failure or interlock fault.
- 12Maintain a plant register listing every guarded machine with asset number, manufacturer, hazard assessment, guard and safeguarding inventory, interlock performance level, inspection schedule, and responsible competent person. The register underpins the Part 4.5 plant duty under the WHS Regulation.
- 13PPE baseline: safety glasses to AS/NZS 1337.1 for impact and chip hazards; Class 4 or 5 hearing protection per AS/NZS 1270; safety footwear to AS/NZS 2210.3; no loose clothing, jewellery, or long hair near rotating plant; cut-resistant gloves only where selected by the task risk assessment and never near rotating chucks, spindles, or rollers where entanglement is a risk.
- 14Psychosocial controls per WHS Regulation 2025 r55A-55D: realistic production targets that do not pressure operators to bypass interlocks; no production bonus schemes that incentivise safeguarding shortcuts; two-person standard for guard reinstatement and light-curtain alignment; clear escalation pathway when a guard is found defective.
- 15Daily pre-start toolbox talk covering the day's production programme, confirmed guard and safeguarding status, any machines under lockout or modified status, and any changes since the previous shift. Record attendance on the SWMS worker sign-on register.
- 16After any guarding-related near-miss, prohibited practice, or incident, conduct an immediate review before resuming work on the affected plant; update the plant register and the SWMS if any deficiency is identified, and notify the regulator within the statutory window if the incident meets the notifiable-incident threshold under Section 36 of the WHS Act.

Worked example
A food manufacturer in Dandenong operates 23 pieces of guarded plant across three production cells — dough mixers, conveyors, wrappers, depositors, ovens, and packaging lines. The WHS lead implements this SWMS to structure the monthly competent-person audit required under Part 4.5 of the WHS Regulation. Each audit follows the checklist: guard integrity verified, fastener torque confirmed, interlock function tested by opening each movable guard against running plant, light curtains verified by breaking the beam at each guarded zone, emergency stops tested, bypass wiring inspected, and signage legibility confirmed. In the March audit, the dough-mixer hinged guard interlock fails the function test — the mixer continues running with the guard open. The lead tags the machine, applies a lockout, and removes it from service. A maintenance fitter replaces the failed magnetic switch, restores the safety circuit, function-tests the interlock, verifies the dual-channel logic, and recertifies the machine. The audit outcome is recorded in the plant register, the training team is notified, and the SWMS is referenced at the next daily pre-start toolbox talk. The mixer is released for production after a supervised test run.

Frequently asked questions
Does machine guarding require a SWMS under the WHS Regulation?
Not automatically. Machine guarding does not appear in the Schedule 1 list of high-risk construction work categories that trigger the mandatory SWMS requirement under Section 299. However, Part 4.5 of the WHS Regulation imposes a comprehensive plant duty that requires documented controls, inspection, and maintenance. A SWMS is the most defensible mechanism for evidencing compliance and underpinning operator training, and is often required by Principal Contractors and procurement teams on industrial and food-manufacturing sites regardless of the Schedule 1 position.
What is the difference between a fixed guard, an interlocked movable guard, and a presence-sensing system?
A fixed guard is bolted or riveted in place and requires a deliberate tool-assisted removal; it is the preferred engineering control under AS/NZS 4024.1801. An interlocked movable guard opens routinely for production access but triggers a stop function when opened, compliant with AS/NZS 4024.1501. A presence-sensing system — light curtain, safety mat, laser scanner — detects a worker approaching the hazard and stops the plant without any physical barrier, and is used where loading or unloading prevents fixed guarding. The hierarchy under the 2023 Plant Code of Practice is fixed guard first, interlocked movable guard second, presence-sensing third.
Do I need to apply lockout every time I open a guard?
For routine production access through an interlocked movable guard, the interlock itself provides the protective stop and lockout is not required for each opening. For maintenance, cleaning, fault finding, or any task that requires the worker to place hands or body inside the machine envelope beyond the guard, full lockout per the separate LOTO procedure is mandatory. The distinction is between routine operator access and maintenance access.
What performance level is required for my interlocks?
The performance level follows from a risk assessment per AS/NZS 4024.1201. For most Category 3 hazards — entanglement, crushing, shearing, cutting on powered industrial plant — Performance Level d (PLd) with dual-channel architecture is the typical outcome. PLe is required for the highest-severity scenarios such as press brakes and guillotines. A competent person must conduct the risk assessment and document the resulting performance-level requirement before interlock selection.
What did the December 2024 Queensland timber-mill and August 2024 Quantumstone prosecutions establish?
The $300,000 fine against the Queensland timber mill followed a fatality on an unguarded de-barker where the worker was performing maintenance without lockout and without any compensating control. The $75,000 fine against Paving Group Pty Ltd (Quantumstone) in SA followed a traumatic conveyor-roller injury where a lower roller guard had been removed without replacement. Both cases confirm that Australian courts treat missing guards and missing safeguarding as serious category-2 WHS offences even where the worker is not killed, and that industrial-manslaughter prosecution is available where a guarding failure causes a fatality.
Is this SWMS compliant with the 1 July 2026 Section 26A changes?
Yes. From 1 July 2026, 34 approved Codes of Practice become legally binding under Section 26A of the amended WHS Act. This SWMS cites the currently-approved Codes that will become binding — Managing the Risks of Plant in the Workplace, Safeguarding of Machinery and Plant (state codes), Managing Electrical Risks, and Managing Noise — and aligns with the AS/NZS 4024 series of technical standards. No amendment is required for the 2026 transition; review is recommended whenever plant modifications introduce new hazards or change the interlock performance-level requirement.
