UV lamp maintenance on printing and curing presses involves the inspection, replacement, cleaning, and decontamination of medium-pressure mercury-vapour, gallium iodide, and iron-doped UV-C lamps fitted to sheet-fed offset, flexographic, and web-press curing stations. The work routinely exposes maintenance technicians to non-ionising ultraviolet radiation, residual surface temperatures exceeding 600°C immediately after shutdown, mercury and metal-halide vapours if a lamp ruptures, and high-voltage electronic ballasts and lamp drivers operating at 400–800V. Each of these hazards requires specific engineering, administrative, and PPE controls before the task can proceed safely.
Under the model Work Health and Safety Act 2011 and the WHS Regulation 2025, a Person Conducting a Business or Undertaking (PCBU) must manage risks to health and safety so far as is reasonably practicable. Part 4.1 of the WHS Regulation 2025 imposes specific duties for managing risks from non-ionising radiation, while Part 4.7 governs hazardous chemicals — relevant to mercury vapour exposure following lamp rupture. ARPANSA Radiation Protection Series 14.1 sets the occupational exposure limits for UV-C radiation that the SWMS controls must achieve.
A Safe Work Method Statement is legally required where the task constitutes High Risk Construction Work under Schedule 3 of the WHS Regulation, and is strongly recommended as a primary risk control for any maintenance task involving energised electrical work, hazardous chemicals, and non-ionising radiation. This SWMS documents the hazards, controls, and verification steps required to comply with sections 19 and 20 of the WHS Act and to demonstrate due diligence under section 27.

High-Risk Construction Work triggered
Lamp drivers, ballasts, and HV ignitor circuits operate at 400–800V and retain stored capacitor energy after isolation, requiring tested de-energisation and capacitor discharge before any conductive contact with lamp terminals
Where this work is carried out as part of construction work, Schedule 3 of the WHS Regulation 2025 classifies it as High Risk Construction Work and a SWMS must be prepared before the work commences (Regulation 299). The SWMS must be available for inspection by the regulator, kept until the work is completed, and retained for at least 2 years if a notifiable incident occurs. Failure to prepare a compliant SWMS attracts penalties of up to $7,500 for an individual or $36,000 for a body corporate under the model WHS Regulation.

Worked example
A maintenance technician at a Melbourne label-printing facility is rostered to replace a failed 200 W/cm gallium-doped UV lamp on the third curing station of a flexographic press. Before commencing, the technician opens this SWMS at the press, signs the worker register, and walks through the pre-start checklist with the production supervisor. The press is shut down, the lamp driver is isolated at the local distribution board, locked out with a personal padlock and danger tag, and tested for dead at the lamp connector with a verified two-pole voltage tester. A 25-minute cooldown is observed and confirmed with an IR thermometer reading 41°C on the quartz envelope. The technician dons a UV-rated face shield, long cotton sleeves, and lint-free cotton gloves, erects an opaque UV barrier around the curing station, and removes the lamp using the manufacturer's cradle tool to prevent drop-and-rupture. The new lamp is wiped with isopropyl alcohol to remove any handling residue, installed, and the housing closed. After re-energisation, a controlled test-fire is performed with all interlocks verified and the area ventilated for ozone clearance before production resumes. The completed SWMS, sign-on register, and isolation certificate are filed in the plant maintenance system as evidence of due diligence under section 27 of the WHS Act.

Frequently asked questions
Do I need a SWMS for routine UV lamp replacement, or only for major overhauls?
A SWMS is mandatory under Regulation 299 whenever the work meets the definition of High Risk Construction Work — which includes work on or near energised electrical services. Even routine lamp changes involve isolation of high-voltage lamp drivers and exposure to non-ionising radiation, so most PCBUs implement a SWMS for every lamp maintenance task as a matter of due diligence under section 27 of the WHS Act, regardless of whether construction-work classification strictly applies.
What PPE is required when handling UV-curing lamps?
At minimum, a UV-rated face shield meeting AS/NZS 1338.1 with appropriate shade for UV-C wavelengths, lint-free cotton gloves for lamp handling, long-sleeve cotton or Nomex clothing covering exposed skin, and safety footwear. If the lamp is suspected of rupture, add a P2 respirator rated for mercury vapour and nitrile outer gloves, and follow the mercury spill response procedure.
How do I respond to a ruptured lamp releasing mercury vapour?
Immediately evacuate the area, isolate the press, and ventilate for at least 30 minutes. Don respiratory protection rated for mercury vapour, use a mercury spill kit containing sulfur powder or proprietary absorbent to capture droplets, and seal all contaminated material in a labelled mercury waste container. Notify the WHS manager and arrange disposal through a licensed hazardous waste contractor. A notifiable incident report to the regulator may be required if anyone required medical treatment.
Can a non-electrical maintenance technician change a UV lamp?
Lamp replacement itself is generally a mechanical task, but the isolation and verification of de-energisation of the lamp driver and ballast must be performed by, or under the direct supervision of, a person competent in low-voltage electrical isolation in accordance with AS/NZS 4836. State electrical licensing requirements determine whether a licensed electrician must perform the isolation step. The SWMS clarifies the competency split between mechanical and electrical components of the task.
How is this SWMS customised for our specific press and facility?
The DOCX template is fully editable. You add your company branding, the press make and model, lamp wattage and dopant chemistry, isolation point identifiers, site-specific access arrangements, and the names and signatures of the workers consulted under Regulation 300. The hazard register and controls are pre-populated to a CIH standard but should be reviewed against your specific equipment and any manufacturer service bulletins.
How often should this SWMS be reviewed?
Regulation 302 of the WHS Regulation 2025 requires that a SWMS be reviewed and revised if the work changes, control measures are revised, a notifiable incident occurs, or a HSR requests review. As best practice, we recommend an annual review and any time a press, lamp type, or ballast model is changed.
