Abstract: At 9:00 a.m. on October 21, 2021, an employee was working from an Altec bucket truck using a Stihl top-handle climbing saw removing limbs from a pine tree. The truck was located alongside the driveway of a residence. The pine tree was approximately 90 feet tall with twin codominant stems. As he moved the bucket, the articulated "elbow" of the boom apparently became lodged on a stub limb on the tree, putting the boom under tension. A coworker on the ground yelled to warn him not to keep moving the lift but it was too late. The stub limb broke and the boom flexed, catapulting the employee out of the bucket about 30 feet onto the protective enclosure over the cab of the truck and then to the driveway. The employee was not wearing a harness or lanyard. He incurred multiple trauma from impact with the bucket truck and the ground and was killed.
