Accident Investigation Summary
Summary Nr: 126008770 Event: 08/12/1999Employee Killed When Struck By Post-Tensioning Device
On August 12, 1999, Employee #1 was operating an Owatonna post-tensioning device, model B, serial # 333487D, at 5,600 psi on a concrete slab. He was releasing the pressure on the 1/2 in. cable that ran through the concrete slab when the concrete fractured and the post-tensioning device lost its base footing. Employee #1 was bending over the device when it jackknifed up and struck him in the head. Although he was wearing a hard hat, he was killed. Causal factors of the accident were (1) the failure of the concrete, despite the fact that it had been strength-tested and was apparently strong enough to tolerate this operation; and (2) the improper position taken by Employee #1 in leaning over the device, which placed him in the danger zone should the machine fail.
