Entanglement in rotating machinery: NSW workers compensation guide

Entanglement in rotating machinery can occur through clothing or a glove catching on a rotating shaft or spindle and a hand or limb being drawn into rollers, augers or transmission parts. The incident history should identify the task, equipment, location and sequence of events rather than relying on the job title alone.

People commonly exposed include manufacturing, agricultural and food-processing workers and fitters, cleaners and maintenance workers. Employment records should identify each person's task, employer and position in the work area when the incident occurred.

Medical records after a entanglement in rotating machinery may identify crush injury and amputation. Each diagnosis should be linked to the event or exposure and to the worker's actual functional change.

After a entanglement in rotating machinery, immediate reporting and safety records may include machine isolated without changing the relevant guard or control position and control-system, emergency-stop and operating data. These records can establish what was known at the time without requiring the worker to repeatedly recount a traumatic event.

• Guarding, lockout, maintenance and SafeWork records where applicable.
• If the facts may meet the WHS Act definition of a notifiable incident, the SafeWork notification reference, inspector correspondence and scene records, without delaying emergency assistance or other action permitted by section 39.

For a entanglement in rotating machinery, the first evidence to preserve includes machine model, attachments, modifications and workpiece and task, cleaning or jam-clearing instruction. It is most useful when dates, people, equipment, duties and later medical histories tell a consistent account.

• CCTV, witnesses and emergency-release chronology.
• Operative reports, nerve testing, therapy and prosthetic evidence.

Medical and psychological evidence after a entanglement in rotating machinery may include first-aid, ambulance and early clinical histories describing the entanglement in rotating machinery sequence and diagnosis-specific examination, imaging and specialist evidence for crush injury, amputation, nerve injury, fracture injury. A diagnosis alone may not answer causation or capacity: the records should explain the work event, symptoms, treatment and practical restrictions.

• Certificates of capacity stating functional restrictions, hours and treatment rather than only a diagnosis.
• Operative, rehabilitation and psychological records where the event caused surgery, prolonged recovery or trauma symptoms.

After a entanglement in rotating machinery, an insurer may dispute whether the machine started unexpectedly or remained energised and whether all crush, nerve, amputation and scar consequences are accepted. The written decision should be answered with evidence directed to those stated reasons.

Severe hand or limb injuries may require staged surgery, nerve repair, rehabilitation or prosthetic care. Functional evidence should address grip, dexterity, reach and endurance rather than diagnosis alone. If treatment is disputed after a entanglement in rotating machinery, the request should explain the accepted diagnosis, expected functional benefit and reasonable alternatives.

Work capacity after a entanglement in rotating machinery may turn on rotating plant, guarding, two-handed controls, dexterity and reaction time and whether alternative work removes plant exposure and matches permanent restrictions. Proposed duties must be compared with the real task demands and the worker's ability to sustain them for the proposed hours.

Limb, amputation, nerve, motion and scar ratings use specific methods and cannot be inferred from the machine type. The accident mechanism, surgery, imaging finding or pain report alone does not establish a WPI percentage. Any WPI assessment after a entanglement in rotating machinery occurs after stabilisation under the NSW method for the accepted body system; the accident or surgery alone does not determine a percentage.

Machine designer, manufacturer, modifier or maintenance contractor issues may need separate investigation. Any separate occupiers-liability, product, TPD or work injury damages issue is distinct from statutory workers compensation and depends on its own evidence and legal criteria. These issues are separate from workers compensation and depend on the particular facts.

For a entanglement in rotating machinery, assistance may involve separate the entanglement in rotating machinery mechanism from the diagnoses and identify any missing incident record and compare the insurer’s written reasons with medical, treatment and work-capacity evidence. The purpose is to identify the disputed decision and the evidence needed for the next step, not to promise an outcome.
