On May 2, 2006, a 23-year-old logger, working as a chaser, was killed when a yarder tipped over and crushed him. The crew was setting up the yarder on a new logging corridor and was in the process of tightening the guylines. The chaser and the siderod (site foreman) worked together to spool the guylines onto guyline drums at the rear of the yarder. The chaser worked on the deck of the yarder on the top two drums, while the siderod worked from the ground on the bottom two drums. As the fourth and final guyline was being spooled, the siderod heard a coworker yelling, and saw the man motioning with his arm over his head, indicating the yarder was going over. He took off running and just made it past the tracks when the yarder toppled backward over the steep hillside. Still on the deck of the yarder, the chaser ran toward the cab, but did not manage to get inside before the yarder went over. The yarder operator inside the cab emerged with minor injuries. CAUSE OF DEATH: Blunt force injuries. RECOMMENDATIONS: 1. Manufacturers should provide enhanced guidance for setting up yarder towers. 2. Extra precautions should be implemented whenever loads approach the tower's maximum capacity. 3. Operators need to consider leaving guyline locking dogs out during initial spooling of the guylines. 4. New loggers should be trained to stay alert for hazards and be prepared for sudden emergencies.
