Power press operation involves cyclic application of multi-tonne closing force through mechanical flywheel-clutch or hydraulic ram systems to stamp, blank, pierce, or form sheet metal components. The die zone is one of the highest-amputation-risk locations in Australian manufacturing, with historical incident data showing that the majority of severe press injuries occur during die setting, troubleshooting jams, or when guarding has been bypassed. Under WHS Regulation 2025 Part 3.2 (Plant), the PCBU must manage risks associated with plant that can crush, cut, or trap, and presses fall squarely within the registered plant design and item registration requirements of Schedules 5 and 5A. A Safe Work Method Statement is mandatory because press operation routinely triggers section 291 a high risk construction work category (powered mobile/fixed plant capable of causing crush or amputation), and because AS 4024.1601 requires documented control selection covering guarding, control reliability, and die-setting procedures before each production run.

Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Elimination — Replace manual hand-feeding with progressive die strip feed or coil-fed automation so operator hands never enter the die closing zone during normal production cycles.
- 2Elimination — Remove jammed parts only after full de-energisation and ram blocking; prohibit reach-in clearing under any powered condition without exception.
- 3Substitution — Specify hydraulic presses with controlled descent and dwell over mechanical flywheel presses for new installations where cycle time allows.
- 4Substitution — Replace open dies with fully enclosed tunnel-style or self-contained die sets that mechanically prevent finger entry to the pinch point.
- 5Engineering — Install Category 4 (AS 4024.1601) light curtains with calculated safe stopping distance, control-reliable two-hand anti-tie-down stations, and monitored guard interlocks.
- 6Engineering — Fit clutch/brake monitoring with stop-time measurement at defined intervals; press auto-disables on overrun beyond AS 4024.1601 tolerance.
- 7Administrative — Issue written die-change permit requiring authorised setter, LOTO isolation per AS 4024.1603, ram safety block in place, and supervisor sign-off before re-energising.
- 8Administrative — Restrict continuous-mode selection to keyed authorisation held by production supervisor only; log every mode change in the press operations record.
- 9Administrative — Pre-start verification of two-hand control function, light curtain alignment, and emergency stop response before first cycle each shift, recorded on the SWMS sign-on.
- 10PPE — Class 1 safety glasses or face shield for blanking work, Class 5 hearing protection where measured levels exceed 85 dB(A), and snug-fitting cuffs without loose gloves near die zone.
Applicable Codes of Practice
Mandates guarding that prevents access to moving parts, control reliability for safeguarding devices, and isolation before clearing or adjusting plant.
Specifies control category requirements for two-hand devices, light curtain stop-time calculation, and die-setting safety blocks applicable to every cycle.
Requires documented isolation, lockout, and verification of zero energy state before any die change, maintenance, or jam clearance on press plant.
Triggers noise exposure assessment, audiometric testing, and hearing protection program where press operations exceed the 85 dB(A) eight-hour standard.
High-Risk Construction Work triggered
Power press ram applies multi-tonne closing force on every stroke, creating an amputation and crushing hazard at the die zone that meets the section 291 criterion for plant capable of severe injury.
PCBU must consult workers, document the SWMS before work starts, monitor compliance, and retain records for two years (or until after an incident). Penalties for breach are substantial and indexed; current maximum follows the prevailing WHS schedule.

Worked example
At a suburban automotive component plant, a setter and operator are starting a 5,000-piece blanking run on a 200-tonne mechanical press. Before energising the machine, the supervisor pulls up the Power Press SWMS at the pre-start board and walks the two-person crew through it. They identify the live hazards for this job: amputation at the die zone, potential clutch-brake overrun, and slug ejection from the blanking station. Working through the control list, the setter confirms the light curtain is aligned and the muting zone is set only for the strip-feed pass-through, two-hand controls test as anti-tie-down compliant within the required response time, and the clutch stop-time monitor reading is within AS 4024.1601 tolerance. The die-change permit from the previous shift is closed out, ram safety block removed, and LOTO tags returned to the board. Both workers sign on to the SWMS, acknowledging single-stroke mode only — continuous mode is locked out because no supervisor key is issued for this job. Two hours into the run, a slug jams in the lower die. Rather than reach in, the operator stops the press, applies their personal lockout per the SWMS jam-clearance step, installs the safety block, and clears the slug. The supervisor notes the jam frequency on the SWMS review section and schedules a die inspection before the next shift.

Frequently asked questions
Does power press work legally require a SWMS?
Press operation in a manufacturing plant is not construction work, so the high risk construction work categories at s291 and the SWMS duty at s299 are not the source of the obligation. The duties that bite are in Part 3.2 of the WHS Regulation 2025 — r203 to r207 on guarding, control reliability and isolation before adjusting plant — together with the energy isolation duty at r188, the noise exposure standard and the primary duty of care at WHS Act s19. A documented safe system of work is required, and this template delivers it in the SWMS format your customers and auditors expect. Check separately whether your press requires plant design or item registration.
Where do press amputations actually happen?
Not during normal cycling. The incident pattern is overwhelmingly die setting, clearing a jam, and running with guarding bypassed — which is why the controls target those three moments specifically. Jams are cleared only after full de-energisation with the ram physically blocked and the operator's own lock applied; reaching in under any powered condition is prohibited outright, with no production exception. Die changes run on a written permit naming an authorised setter, with lockout to AS 4024.1603, the safety block in place, and a supervisor signature required before the press is re-energised.
Is a light curtain enough on its own?
No, and on a mechanical press it can be actively misleading. A light curtain stops the stroke that has not yet started; it does nothing about a repeat or double stroke caused by a worn clutch or brake, which closes the die while the operator's hand is still inside on what they believed was a completed cycle. The template pairs Category 4 light curtains to AS 4024.1601 — installed at a calculated safe stopping distance, with muting limited strictly to the strip-feed pass-through — with clutch and brake monitoring and periodic stop-time measurement, and the press auto-disabling on overrun beyond tolerance.
How do we stop operators defeating the two-hand controls or selecting continuous mode?
By making both physically and administratively hard rather than relying on instruction. Two-hand stations must be control-reliable anti-tie-down types, tested for response as part of the pre-start check each shift alongside light curtain alignment and emergency stop response. Continuous mode is restricted to keyed authorisation held by the production supervisor, with every mode change logged in the press operations record — so a job running single-stroke only has no key issued for it. Operators sign on to the mode they are working in, which puts the record where an investigation would look for it.
Does one template cover mechanical and hydraulic presses?
Yes. The hazard set spans both — flywheel-clutch machines bring the repeat-stroke risk, hydraulic rams bring stored-energy descent during die change, and both share the die-zone amputation hazard, slug and scrap ejection during blanking, and impact and air blow-off noise above 85 dB(A). You receive an editable Microsoft Word document, bought once, with the hazard register mapped to the hierarchy of control, a state-specific legislation schedule for all eight jurisdictions, a sign-on register and a pre-start checklist. Edit it to name your presses, tonnages, die sets and feeding method before the first brief.
