Tree trimmer dies after 40-foot fall in aerial bucker - Virginia.
Morgantown, WV: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, FACE 97-12, 1997 Oct; :1-3
A 29-year-old male tree trimmer (the victim) died after falling 40 feet with the aerial bucket from which he was working. The victim was trimming trees in a powerline right-of-way while working from an aerial bucket mounted on a log skidder. A ground man, facing away from the victim, was picking up the fallen limbs when he heard a snapping sound similar to that of a limb breaking. When the ground man turned, he saw that the bucket's extended boom had broken, 5 feet from its base, and had fallen to the ground. The victim, tied off to the anchor point in the bucket, had fallen to the ground inside the bucket. The ground man immediately alerted the supervisor, who summoned the rescue squad from a radio in the company truck. The rescue squad arrived within 10 minutes and transported the victim to the hospital, where he was pronounced dead by the attending physician. NIOSH investigators concluded that, to prevent similar incidents, employers should ensure that machine operators perform daily maintenance checks on machinery before beginning operations. Additionally, manufacturers should explore alternative methods of mounting after-market boom apparatus to machinery that would place the least amount of stress on the apparatus' components, and evaluate the materials used in the manufacture of these components.
