Worker Fatality During Trench Box Dismantling

A work crew was on location to dismantle a high arch trench box and then transport the disassembled box from one project work site to another. The disassembly process did not follow the manufacturer's instructions for the safe removal of the strut support pins holding the box together. Consequently, when the last strut support pin was removed from the box, it collapsed, causing a support arch to strike and fatally injure a worker.
