Using rope access for job within the inside the utility leg platform.
All work conducted on night shift.
The root cause of this incident comes down to failure to identify the hazard (tight access and abrasive concrete wall) and failure to consider that the harness may rub against the wall (job planning and risk identification).
There were occasions when the hazard could have been identified by parties involved:
Recommend regular site surveys
Better hazard awareness and understanding by all
Pre-use equipment checks before each shift
Regular communication with all staff involved
