Abstract: On August 5, 2002, Employee #1, a driller/laborer, was assisting a drill rig operator and supervisor in digging pilings for new construction. The coworker was operating an LMFB-60 LoDrill with an attached Kelly Bar. The Kelly Bar had hydraulically-operated metal sleeves that telescoped down, allowing the drill operator to quickly lower a drill bit or clean-out bucket as far as 80 ft into the ground. Employee #1 was opening the gate to a clean-out bucket attached to the Kelly Bar when he propped his hand on the inner sleeve of the bar for stability. The outer sleeve slipped down, crushing the hand of Employee #1. The employee sustained multiple fractures to all of his fingers of his right hand, resulting in significant loss of function and permanent scarring.
