INC-2026-0412 · Conveyor CV-07 hand laceration
Roller change on conveyor CV-07. A fitter sustained a laceration to the left hand when the belt moved unexpectedly during maintenance. Investigation submitted: belt still energised, isolation not verified; fitter did not apply a personal lock. Corrective action: retrain the fitter on the isolation procedure. Severity coded MTI; regulator notified within 24 h.
Evidence-grounded and compliant on notification, but a single-point human-error conclusion: it omits 3 of 4 ICAM layers and its only corrective action targets the individual, not the systemic defences. Route to HSE reviewer.
