Web Threading & Splicing SWMS

Web threading and splicing on web-fed printing presses is one of the most hazardous routine tasks in a print facility because it requires workers to guide substrate through multiple nip points, roller trains, and drying systems while the press operates at inching speed. Even at reduced speed, the forces generated by tensioned web and rotating cylinders are sufficient to cause entanglement injuries, severe lacerations, and fatal crush events. Flying splice systems that execute reel changes at full production speed add further risk from high-speed web movement and adhesive tape dispensing mechanisms. This SWMS template covers manual web threading, flying splice operations, and tension adjustment with controls mapped to the Managing Risks of Plant code.

Legal Requirements

section 26a binding

Yes — Plant code binding July 2026. Non-compliance is admissible as evidence of breach.

Hazards

HazardConsequenceLikelihood
Entanglement in roller nip points during web threading at inching speedFatal crush injuries, amputation, deglovingPossible
Lacerations from tensioned web edge during threading and tension adjustmentDeep lacerations to hands and armsLikely
Entrapment in flying splice mechanisms during reel change preparationCrush injuries, amputationUnlikely
Struck by reel during loading and positioning on unwind standCrush injuries, fractures, fatalityUnlikely
Manual handling injuries from reel loading and web tension adjustmentMusculoskeletal injuries, back strainLikely

Controls (Hierarchy of Controls)

Use dedicated web threading devices and ropes to avoid manual contact with nip points during threading
Ensure all personnel are clear of nip points before commencing inching mode operation
Maintain nip guards on all roller pairs and verify guard position before threading
Implement two-person procedures for web threading on multi-unit presses
Use mechanical reel handling equipment for all reel loading and positioning
Restrict flying splice speed adjustments to authorised personnel with documented competency
Install emergency stop pull cords along the full length of the web path

Recent Prosecutions

Web press entanglement — NSW$450,000

A press assistant suffered a fatal crush injury when entangled in the roller train of a web offset press during a manual threading operation. The nip guards had been removed to facilitate threading and the press was operated in inching mode without a spotter.
