• Description:
  During February 1999, a 62-year-old self-employed tree trimmer died after falling 35 feet from the bucket of a boom truck and landing on the frozen ground. The 2-piece hydraulic lift arm was in an extended vertical position when a hydraulic safety valve on the main hydraulic cylinder snapped off, causing the lift arm to collapse and the bucket to immediately fall to the ground. The victim rode with the bucket and was thrown out of the bucket after it hit the ground. The man died shortly thereafter from hepatic rupture and internal bleeding. Recommendations based on our investigation are as follows: 1. Hydraulic fittings should be designed to withstand the stress and fatigue encountered in normal use. 2. Engineering interventions should be developed to prevent boom lift fall in case of hydraulic failure.
