WHS Management for UV Curing Operations

Manage the dual exposure risk of formaldehyde and ozone from UV curing systems with controls mapped to incoming WELs.

UV curing technology is now standard across offset, flexographic, screen, and digital printing operations, but it introduces hazards that many printing businesses have not fully assessed. The UV curing process generates formaldehyde as a by-product of photoinitiator decomposition and ozone from UV-C radiation interacting with ambient oxygen, creating a dual chemical exposure risk. Both substances face significant WEL reductions in December 2026 — formaldehyde dropping 70 per cent to 0.3 ppm and ozone dropping 50 per cent to 0.05 ppm. UV radiation itself poses acute skin burn and eye injury risks during lamp replacement and maintenance tasks. A dedicated WHS management plan for UV curing operations is essential for any print facility running UV-equipped presses or coating systems.
