A 42-year-old skid worker received a serious injury when a log swung round in an arc and hit him. His ribs were fractured and lungs punctured.
The skidder operator released the drag of five logs. The skid worker was unable to release two of the logs. He signalled the operator to pull these logs forward and back off.
The skidder operator tensioned the rope backed up over the logs and strops. He then drove forward and turned the machine, causing a log to strike a stationary log which swung and hit the worker, who was moving forward to unhook the logs.
The investigation determined that the:
- skidder operator did not follow the signals given
- skid size was too large and resulted in the machine turning to move away from the released drag.
WorkSafe New Zealand advice
- Ensure signals are followed.
- Drive directly forward until all chain strops are unhooked and free of the logs.
- If for any reason the machine must turn to proceed from a released drag, the skid worker must be positioned clear of any log that may swing.
