Logger and logging supervisor killed by uprooted tree.
NIOSH 2001 Nov; :1-12
An uprooted tree struck and killed a 34-year-old logging supervisor and a 33-year-old logger (the victims). The victims were part of a six-man crew using a crane to move cut timber from a slope to a road. The mobile crane, known as a "yarder," was located on the road above the slope. It was anchored by a single guyline to an uncut tree on the hillside above the road. At the time of the incident, the yarder was attempting to pull a set of logs up the slope. During two previous attempts or "turns," the logs had become hung-up on a stump. The two victims were standing near the yarder when a third "turn" was started. The logs hung-up again. The tree that was anchoring the yarder uprooted and fell toward the yarder. A co-worker working on the slope below the road (the witness) saw the tree fall toward the yarder. He yelled to a co-worker to radio for help and climbed up the slope to the road where other workers met him. Both victims were found under the uprooted tree. CPR was performed but stopped when there was no detectable response. Alaska State Troopers were notified and the bodies recovered. The victims were pronounced dead at the scene. Based on the findings of the investigation, to prevent similar occurrences, employers should: 1. Ensure that all crewmembers are capable of recognizing hazardous conditions and are authorized to stop work so that work procedures can be modified in accordance with safe logging and timber harvesting methods. 2. Ensure that all skylines and guylines are anchored to stumps; 3. Ensure that all personnel involved in rigging of cable yarding systems are trained in selecting and rigging anchor stumps.
