Abstract: At 11:15 a.m. on March 9, 2017, Employee #1 and Coworkers #1 and #2, employed by a lumber company, were working at the truss table. Employee #1 was assisting Coworker #1, the truss assembler, to place 2 by 4 lumber boards on the truss table. The lumber then would be assembled and moved with the ejection rollers. Employee #1 completed his task. Coworker #2 then released the pneumatic pressure valve to bring the rollers back down under the table's working surface. Employee #1's right hand was in the area of the pinch point when the guarded roller track moved downward, striking and crushing Employee #1's hand. Emergency services were called, and Employee #1 was transported to the hospital. He was treated for partial amputation of his right hand's ring finger.
