Abstract: At 10:00 a.m. on November 14, 2019, Employee #1 and a coworker, a forklift operator, were working on a commercial construction project. Employee #1 was removing bolts from a bin jack attached to a 6,300 lbs., (center ring for the roof of a digester tank). The coworker lowered the center ring section of a large digester tank to a Jib of a fully extended, JCB 512 rough terrain, forklift and Employee #1 then placed himself under the galvanized center ring of the 6,300 lbs. ring. As Employee #1 pried on the bin jack to remove a bolt, the bolt finally became free and the rough terrain forklift center and outer ring then fell on and crushed Employee #1 on the concrete floor below. The coworker then worked to try to move the boom and the ring off of Employee #1; however, after being crushed by the weight of the steel ring, Employee #1 then sustained fatal injuries to the chest and head and was killed.
