Abstract: On January 10, 2002, Employee #1 was standing on the ground, next to a drilled "pier" foundation hole top casing. Employees were using a round steel pipe for temporary shoring and concrete forms. Another employee was operating a Grove 50-ton Hydraulic crane, Model number RT75S, Serial number 23246. The crane was positioned to extract the steel top casing from the ground. The crane operator, who was inexperienced, lowered the boom without laying out additional wire rope on the whip line. The headache ball two-blocked at the boom tip, parting the line, which allowed the ball to free fall and strike Employee #1 on the shoulder. The operator was not trained for this equipment and tested positive for marijuana. Employee #1 was hospitalized with a fractured left shoulder and ribs.
