Industrial additive manufacturing using Selective Laser Sintering (SLS), Selective Laser Melting (SLM) and industrial Fused Deposition Modelling (FDM) printers introduces a unique convergence of hazardous energy sources, respirable powders and thermal decomposition products that are not present in conventional CNC or subtractive workshops. Metal powders such as titanium, aluminium and stainless steel are pyrophoric and explosible at concentrations above their Minimum Explosible Concentration, while polymer powders generate ultrafine particulates that penetrate deep into the respiratory tract. Class 4 fibre and diode lasers used in SLM and SLS systems emit invisible near-infrared radiation capable of causing instantaneous retinal burns and skin necrosis. Under WHS Regulation 2011 r291 and the harmonised 2025 amendments, a documented Safe Work Method Statement is mandatory because this work involves multiple Schedule 1 high-risk categories operating concurrently — hazardous chemicals, plant with non-guarded energy sources, and confined-space build chambers. A SWMS is the only mechanism that legally evidences hazard identification, control selection and worker consultation before powder handling, build initiation or post-process depowdering commences.
Hazards identified
7 hazards covered, sorted by priority.
Deflagration or explosion causing fatal blast trauma, severe thermal burns, structural damage and prosecution under WHS Reg r361
Permanent retinal photocoagulation, corneal burns, full-thickness skin necrosis within milliseconds of exposure to direct or specular beam
Metal fume fever, occupational asthma, pulmonary fibrosis and confirmed Group 1 carcinogen exposure from hexavalent chromium and nickel oxides
Spontaneous ignition causing localised fire, severe hand and facial burns, and secondary dust explosion propagation through extraction ductwork
Rapid loss of consciousness without warning at oxygen levels below 19.5%, fatal anoxia within minutes, no olfactory warning signs
Partial and full-thickness burns to hands and forearms requiring skin grafting, lost-time injury and notifiable incident under r699
Lumbar disc injury, chronic musculoskeletal disorder and workers compensation liability under WHS Reg Part 4.2 manual task provisions
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Replace pyrophoric fine metal powders with coarser >45 micron grades or shift selected geometries to wire-arc DED where dust cloud risk is eliminated entirely.
- 2Elimination — Decommission unattended overnight builds in occupied buildings; relocate SLM cells to dedicated fire-rated enclosures with no human occupancy during operation.
- 3Substitution — Substitute reactive titanium/aluminium powders with stainless or tool-steel alternatives where mechanical performance specification allows, reducing explosibility class from St3 to St1.
- 4Engineering — Install Class 1 laser enclosures with dual-redundant interlocks compliant with AS/NZS IEC 60825.1, beam-stop verification and key-controlled service access.
- 5Engineering — Provide ATEX-rated wet vacuum depowdering stations, conductive grounded benches (<10⁶ ohm) and inert-gas glove boxes for powder transfer below MEC threshold.
- 6Engineering — Fit continuous oxygen depletion monitors set at 19.5% alarm and 18% evacuation, interlocked to extraction and audible/visual annunciators per AS 1668.2.
- 7Administrative — Mandatory Hot Work Permit, powder-handling permit and laser-safety officer sign-off before any build chamber opening, with two-person rule during depowdering operations.
- 8Administrative — Competency verification via documented training in AS/NZS IEC 60825.14 laser safety, dust explosion awareness (HB 211) and SDS review for every powder batch.
- 9PPE — Flame-resistant antistatic coveralls (EN 1149-5), nitrile inner plus leather outer gloves, AS/NZS 1337.1 laser safety eyewear matched to wavelength and optical density.
- 10PPE — P3 powered air-purifying respirator with HEPA cartridge for depowdering tasks, face-fit tested annually per AS/NZS 1715, plus AS/NZS 2210.3 safety footwear with antistatic soles.
Applicable Codes of Practice
Mandates Class 4 laser enclosure standards, interlock integrity and Laser Safety Officer appointment directly applicable to SLM and SLS beam delivery systems.
Requires hazardous zone classification (Zone 20/21/22) around powder handling, sieving and depowdering stations, dictating ATEX equipment selection and ignition control.
Establishes SDS review, manifest quantities and emergency planning duties for metal powders classified as flammable solids under the GHS.
Applies to hot work, post-process heat treatment and metal powder bed fusion as an allied thermal process requiring fire watch and combustible clearance.
High-Risk Construction Work triggered
Fine metal and polymer powders below 500 microns meet the definition of hazardous chemicals with explosibility class St1–St3 under GHS classification.
SLM and SLS systems use 200W–1kW fibre and CO2 lasers exceeding Class 3B/4 thresholds capable of causing immediate permanent injury.
Build chamber venting and depowdering releases respirable metal condensate, ultrafine particulates and pyrolysis products exceeding workplace exposure standards.
PCBU must consult workers, retain the SWMS for the duration of the work plus two years post-incident, and produce on inspector request — penalties are substantial and indexed, with the current maximum following the prevailing WHS schedule.

Worked example
At a mid-sized contract additive manufacturing bureau producing titanium aerospace brackets, the morning shift supervisor convenes a pre-start brief at 0645 in front of the SLM 280 cell. She opens this SWMS on the workshop tablet and walks the three-person crew through the hazard register, pausing on the pyrophoric powder line item because today's build uses a freshly opened Ti-6Al-4V batch with finer particle size distribution than the previous lot. The operator confirms the grounding strap continuity reading on the depowdering glovebox is below 10⁶ ohms, ticks the engineering control as verified, and signs the SWMS sign-on sheet. Mid-shift, the oxygen depletion alarm in the printer room briefly chirps at 19.7% during an argon top-up. Rather than silencing it, the operator pauses the build via the e-stop, evacuates to the muster point and refers back to the SWMS — which directs that any O2 reading below 19.5% requires LSO clearance before re-entry. The Laser Safety Officer attends, confirms the leak source at the regulator union, isolates the supply, and the SWMS is annotated with the deviation. The crew re-signs the document before resuming depowdering in P3 PAPR and antistatic coveralls, demonstrating the SWMS functioning as a live field control rather than a filed document.
