Saw, grinder, drill, press or cutting-machine accident: NSW workers compensation guide

Saw, grinder, drill, press or cutting-machine accident can occur through a blade or disc contacting the worker after kickback or loss of control and material binding, shattering or being ejected. 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 tradespeople, fabricators and construction workers and manufacturing, maintenance and workshop workers. Employment records should identify each person's task, employer and position in the work area when the incident occurred.

Medical records after a saw, grinder, drill, press or cutting-machine accident may identify hand injury and hand tendon injury. Each diagnosis should be linked to the event or exposure and to the worker's actual functional change.

After a saw, grinder, drill, press or cutting-machine accident, immediate reporting and safety records may include retain the tool, guard, disc, blade, workpiece and settings and pre-start, inspection, maintenance and modification records. These records can establish what was known at the time without requiring the worker to repeatedly recount a traumatic event.

• Work-area photographs, CCTV 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 saw, grinder, drill, press or cutting-machine accident, the first evidence to preserve includes manufacturer instructions, training and the task procedure for the actual saw, grinder, drill, press or cutting machine and guard, blade or disc condition and whether the workpiece was supported, chocked or able to bind and cause kickback. It is most useful when dates, people, equipment, duties and later medical histories tell a consistent account.

• Power state, isolation and whether clearing or adjustment was underway.
• Exclusion-zone, PPE and projectile or fragment evidence.
• Surgery, hand therapy, nerve, tendon and vision records.

Medical and psychological evidence after a saw, grinder, drill, press or cutting-machine accident may include first-aid, ambulance and early clinical histories describing the saw, grinder, drill, press or cutting-machine accident sequence and diagnosis-specific examination, imaging and specialist evidence for hand injury, hand tendon injury, hand nerve injury, eye 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 saw, grinder, drill, press or cutting-machine accident, an insurer may dispute whether the event caused tendon, nerve or eye damage beyond the initial wound and whether later grip or fine-motor limits are supported by objective findings. The written decision should be answered with evidence directed to those stated reasons.

Lacerations may require tendon, nerve or vascular repair, while eye injuries require separate assessment. Hand therapy and graded duties should match the repaired structures and functional findings. If treatment is disputed after a saw, grinder, drill, press or cutting-machine accident, the request should explain the accepted diagnosis, expected functional benefit and reasonable alternatives.

Work capacity after a saw, grinder, drill, press or cutting-machine accident may turn on grip, pinch, dexterity, vibration, two-handed control and eye protection and whether tool-free or one-handed work is actually available and safe. Proposed duties must be compared with the real task demands and the worker's ability to sustain them for the proposed hours.

Upper-limb, digital nerve, motion, amputation or vision methods may apply; surgery and scarring do not by themselves establish WPI. The accident mechanism, surgery, imaging finding or pain report alone does not establish a WPI percentage. Any WPI assessment after a saw, grinder, drill, press or cutting-machine accident occurs after stabilisation under the NSW method for the accepted body system; the accident or surgery alone does not determine a percentage.

A defective tool, disc, guard or machine may require a separate product or contractor 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 saw, grinder, drill, press or cutting-machine accident, assistance may involve separate the saw, grinder, drill, press or cutting-machine accident 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.
