Abstract: On August 21, 2002, Employee #1 and coworkers were harvesting prunes in a Westermann Farm orchard. Employee #1 was operating a shaker harvester when the canvas wrapping around a tree trunk caused a problem with the harvester. Without turning off the unit, he rose from his seat and leaned inward between the shaker's main canopy cover and the hydraulic system. Without warning, a hydraulic bar descended, crushing Employee #1's right hand. He sustained severe fractures, as well as lacerations to several fingers. Emergency personnel transported Employee #1 to Enloe Medical Center in Chico, CA. He was later hospitalized at a San Francisco hospital for treatment.
