A 38-year-old trained and experienced logger was killed when he was struck by a tree.
A multi-leader radiata pine tree had been scarfed and back-cut. Only a small section of holding wood had been left.
The heads of the multi-leader appear to have been caught in a tree forward of the multi-leader and this prevented it from falling.
The tree faller walked forward to fell the tree that had prevented the multi-leader from falling. Positioned with his back to the cut-up tree, he began to make his felling cuts.
It is thought that as the tree faller was cutting the obstructing tree it moved and released the cut-up tree. The tree fell on him and he was fatally injured.
The investigation determined that the accident was caused by:
- working forward of a cut-up tree
- felling aids not being used
- scarf cut too deep with not enough holding wood left
- a failure to clear round the base of the cut-up tree. the tree faller was unable to gauge the depth of the back-cut
- the tree forward of the multi-leader should have been felled first
- the multi-leader should have been driven out with another tree.
WorkSafe New Zealand advice
