Abstract: At about 1:30 p.m. on July 10, 2006, Employee #1, a full-time employee of a company that manufactured reinforced concrete pipe, was removing the three pins of a three-way hoisting chain from the top lid of a 16-ft and 3.25-in. high, 36-in. diameter steel core, located in the casting department of the facility. Employee #1 was standing on the outer cage of the core during removal of the pins and as he removed the final pin, the top lid shifted downward to set itself in place. Employee #1's left hand slipped from the pin housing due to oil on the pins and his glove, and he fell about 11 ft to the concrete floor. He sustained a compound fracture of his right wrist and broken bone injuries of his left ankle. He was hospitalized. .
