UV Lamp Maintenance SWMS

UV lamp maintenance in printing facilities involves direct exposure to UV radiation, residual ozone and formaldehyde, high-voltage electrical components, and surfaces at temperatures exceeding 400 degrees Celsius. Lamp replacement, reflector cleaning, and power supply servicing require workers to access areas of the press that are normally enclosed and shielded during operation. The WEL reductions for formaldehyde to 0.3 ppm and ozone to 0.05 ppm arriving in December 2026 mean that even residual concentrations present during maintenance activities will require atmospheric verification before and during work. This SWMS template covers UV lamp inspection, replacement, reflector cleaning, and power supply maintenance with controls mapped to applicable codes of practice.

Legal Requirements

regulation

WHS Regulation 2025 Part 7.1 — Hazardous Chemicals; Part 5.2 — Plant; Part 4.5 — Electrical

hrcw category

Hazardous chemical exposure, work near energised electrical installations

section 26a binding

Yes — Both codes binding July 2026. Non-compliance is admissible as evidence of breach.

Hazards

Hazard	Consequence	Likelihood
UV radiation exposure from unshielded lamps during inspection and replacement	Photokeratitis (arc eye), UV skin burns, long-term skin cancer risk	Possible
Ozone and formaldehyde inhalation from residual atmospheric contamination	Respiratory irritation, pulmonary oedema, chronic respiratory disease	Possible
Electrical shock from high-voltage UV lamp power supplies	Electrocution, cardiac arrest, electrical burns	Unlikely
Thermal burns from lamp assemblies and reflectors at operating temperature	Second and third degree burns	Possible
Mercury exposure from broken UV lamps containing mercury vapour	Acute mercury poisoning, chronic neurological damage	Unlikely

Controls (Hierarchy of Controls)

Allow UV lamp assemblies to cool to below 60 degrees Celsius before commencing maintenance — verify with infrared thermometer

Conduct atmospheric monitoring for ozone and formaldehyde before entering UV curing enclosures

Implement lockout-tagout on UV lamp power supplies before any maintenance work begins

Provide UV-blocking safety glasses (AS/NZS 1337.1) and long-sleeved clothing for UV protection

Use mercury spill kits and documented mercury clean-up procedures for broken lamp incidents

Ensure adequate ventilation of UV curing enclosures during and after maintenance work

Restrict UV lamp maintenance to trained personnel with documented electrical competency

Recent Prosecutions

UV radiation workplace exposure — Victoria$165,000

A worker sustained severe UV burns to exposed skin and photokeratitis after a UV curing system was operated with a defective shutter mechanism that allowed radiation exposure during a press stoppage. The employer had not maintained the shutter interlock system.
